Description

CLAMPING SYSTEM FIELD OF THE INVENTION The present invention relates to fastening systems. Specifically, the present invention relates to receiver components for use in conjunction with suitable coupling components in a fastening system. This invention was developed in accordance with a joint research agreement between The Procter & Gamble Company and Mitsui Chemicals Inc.

BACKGROUND OF THE INVENTION Adjustable mechanical clamping systems can be used in a wide variety of applications. For example, such indexable fastening systems may be used to connect a portion of a disposable absorbent article to another portion of said disposable absorbent article. In general, the mechanical fastening systems comprise a receiver / female component and a coupling / male component. In some mechanical fastening systems, the coupling member comprises a plurality of hook elements, and the receiving component comprises a plurality of loop elements. When they are fastened, generally, the hook elements are interlocked with the elements with clips so that a connection is formed between the coupling components and the receiver components. Non-woven fabric wefts are known in the industry as materials potentials to be used as the female component. Generally, a female non-woven fabric component comprises a plurality of polymeric fibers. Some portions of these fibers may be joined together by inter-fiber linkages to form a web having sufficient unbound fibers available or unbound portions of bonded fibers and web integrity. The bonds between fibers, generally, are formed by melting portions of fibers together through, for example, heat, pressure or sound (ie, ultrasonic) energy. In some processes a pair of heated calendering rollers can be used to create these inter-fiber bonds. Generally, one of the calender rolls comprises a plurality of projections extending outwardly from its outer surface. A constant force is generally applied to one of the calender rollers in such a way that as the nonwoven fabric web passes between the calendering rollers, the projections apply pressure to the nonwoven fabric web. In the place where the pressure is applied, generally, at least one bond between fibers is created. In general, the nonwoven webs to be used as receiving components are not completely bonded, for example 100% bond between fibers. Since the joints between the fibers generally produce the bonded areas that can not be coupled with a coupling component, by attaching the nonwoven fabric web completely, a low yielding receptor component can be obtained. Therefore, the projections extending outwardly from the outer surface of the calender roll are generally separated in such a way that a particular bonding pattern is created in the non-woven fabric. In addition, it may be desirable for the unattached areas to be large and open, such that when a hook of the coupling component is placed, a non-bonded fiber or an unbonded portion of a bonded fiber becomes available for coupling the hook. Without However, a bonding pattern that results in large open unbonded areas may have a low resistance in the transverse direction to the machine due to the reduced amount of inter-fiber bonding in unbonded areas. To compensate for this, some binding patterns can produce completely enclosed areas, for example, fully bonded fibers that surround unbound fibers. However, a bonding pattern that produces fully bonded fibers surrounding unbonded fibers can reduce the likelihood that there is some unbonded fiber available to which a hook of a coupling component can be attached. further, the bonding pattern can negatively affect the quality of the joints between fibers. For example, since conventional bonding patterns do not completely unite the nonwoven web, the pressure applied to the web as it passes through the calender rolls may fluctuate. In some cases, pressure fluctuations may generate higher pressures at some fiber-binding sites and lower pressures at other fiber-bonding sites. Higher pressure can produce excess bonding or even cutting through the fibers (and this weakens the resulting frame). The lower pressure can result in a reduction in the percentage of bonded area that is formed, compared to the desired percentage for the bond area; in a resistance to the minor union; and / or in a lower quality of the union. In addition, the lower pressure can result in reduced resistance in the cross machine direction. Accordingly, there is a need to provide a fastening system that includes a receiving component with a bonding pattern that reduces the pressure fluctuations experienced by the receiving component during processing and that at the same time maintains a sufficient number of non-fiber areas. joined or unattached portions of bonded fibers.

Description The fastening systems manufactured in accordance with the present invention comprise receiving components that can reduce the pressure fluctuations that may occur when manufacturing the receiving component. Specifically, the receiver components manufactured in accordance with the present invention comprise a binding pattern that can reduce the pressure fluctuations experienced by the receptor component during processing. In addition, a receiving component made in accordance with the present invention can maintain a sufficient area of unbound fibers or unbound portions of bonded fibers such that the receiving component can be used with suitable coupling components in a fastening system.

As illustrated in Figure 1A, a fastening system 10 made in accordance with the present invention may comprise a coupling component. 12 and a receiver component 100. The coupling component 12 may comprise a plurality of hooks 14 extending outwardly from a mating surface 16. The receiver component 100 may comprise a plurality of looped fibers (not shown) capable of becoming entangled with the plurality of hooks 14 of the coupling component 12. Some examples of suitable coupling components are considered below. The fastening system 10 can be used in various commercial and consumer articles that can benefit by having the fastening system of the present invention. Some examples of articles in which the fastening system of the present invention may be used include disposable absorbent articles, body wraps, wrappers and industrialized connections for abrasive pads, medical products and the like. As illustrated in Figure 1 B, the receiver component 100 made in accordance with the present invention may comprise a plurality of tie lines, a tie zone 130 and a plurality of consecutive track regions. In some embodiments, the receiver component 100 may comprise a first link line 10, a second link line 112 and a third link line 114. Modes having more than three link lines and less than three link lines are contemplated. . In some embodiments, the first tie line 110 may be located adjacent a first terminal edge 151 and the second tie line 112 may be located adjacent the first tie line 110. In some embodiments, the third tie line 114 may be located adjacent a second terminal edge 152 and the second joint line 112. In some embodiments, the first terminal edge 151 and the second edge The terminal can extend from a first longitudinal edge 170 to a second longitudinal edge 172 in a direction generally parallel to a lateral axis 162. As illustrated, in some embodiments, the first connecting line 110, the second connecting line 112 and the third Binding line 114 may extend in a first direction 1222 from a first longitudinal edge 170 to a second longitudinal edge 172 of the receiving component 100. In some embodiments, the first direction 1222 may be generally parallel to the lateral axis 162. The first longitudinal edge 170 and the second longitudinal edge 172 may extend between the first terminal edge 151 and the second terminal edge 152 in a direction generally parallel to a longitudinal axis 160. The receiver component 100 also comprises the attachment zone 130. The attachment zone 130 circumscribes more of a line of union. For example, as illustrated, the joint zone 130 may circumscribe the first joint line 10 and the second joint line 1 12. In some embodiments, the joint zone 130 may comprise a rectangle that comes in contact with the points. outermost of the first connecting line 1 10 and the outermost points of the second connecting line 1 12. In some embodiments, the outermost points of the first connecting line 1 10 are the points of said first joining line 1 10 which are closer to the first terminal edge 151, closer to the first longitudinal edge 170 and closer to the second longitudinal edge 172. Similarly, in some embodiments, the outermost points of the second joint line 12 are the points of said second joining line 1 12 which are closer to the second terminal edge 152, the first longitudinal edge 170 and the second longitudinal edge 172. In some embodiments, the third connecting line 14 and overlap in the junction zone 130 adjacent a second boundary 134 of the junction zone 130. In some embodiments, some additional bond lines may overlap in the junction zone 130 adjacent to a first junction. limit 132 or second limit 134. A plurality of consecutive passing regions 140, 142, 144 and 146 may be located within junction zone 130. A pass region comprises a portion of receiver component 100, and is used to analyze the joined area and the total area of the portion of the receiving component 100 within that passing region. An advantage of the pass regions with shorter lengths 175 is that practically more data points can be collected in the junction lines. The greater number of data points can increase the accuracy of calculating the variability in the binding area of the receiver component 100. The accumulated lengths 175 of the pass regions 140, 142, 144 and 146 are equal to the length of the zone of junction 130. Each pass region 140, 142, 144 and 146 comprises a portion of the first junction line 110 or of the second junction 112. In some embodiments, some of the consecutive pass-through regions 140, 142, 144 and 146 may comprise portions of additional tie lines that overlap in the junction zone 130 adjacent the first terminal edge 151 or the second terminal edge 152. For example, since the third tie line 114 overlaps the junction zone 130, the pass region 146 may further comprise a portion of the third tie line 114. At least one track region comprises a portion of the first tie line 110 and the second tie line 1. 12. For example, as illustrated, in some embodiments two pass regions, i.e., 142 and 144, comprise a portion of the first junction line 110 and the second junction line 112. Depending on the sizes of the pass regions, one or more pass regions may comprise portions of more than one junction line. Modalities comprising more than four pass regions and fewer than four pass regions are contemplated. Since the pass regions 140, 142, 144 and 146 are consecutive, each pass region shares a boundary with an adjacent pass region. For example, pass region 140 shares a boundary with pass region 142. Similarly, pass region 144 shares a boundary with pass region 142. However, pass regions 140, 142, 144 and 146 are arranged in such a way that the odd pass regions (first and third), for example, 140 and 144 do not share a limit. In addition, the pass regions 140, 142, 144 and 146 are arranged in such a way that the even pass regions (second and fourth), for example, 142 and 146, do not share a limit. The consecutive passing regions 140, 142, 144 and 146 are rectangular and extend from the first longitudinal edge 170 to the second longitudinal edge 172 of the receiving component 100. The consecutive passing regions 140, 142, 144 and 146 have a width 177 which can be equal to a width of a web of fibrous material that the receiving component can comprise. The width 177 may be generally parallel to the lateral axis 162. In some embodiments, the pass regions 140, 142, 144 and 146 may have the length 175 which is equal to a contact length 250 (illustrated in Figure 2B) between rollers. calandradores. In some embodiments, the pass regions 140, 142, 144 and 146 may have the length 175 which is less than the contact length 250 (illustrated in Figure 2B). In some embodiments, the length 175 may be from about 0.1 mm to about 1.2 mm or any individual number within the range. The length 175 may be generally parallel to the longitudinal axis 160. Each of the pass regions 140, 142, 144 and 146 comprises the length 175 which is equal to the length 175 of adjacent pass regions. Further, as illustrated, in some embodiments the pass region 140 may share the first boundary 132 with the junction zone 130. Also, in some embodiments, the pass region 146 may share the second boundary 134 with the junction zone. 130 Each pass region 140, 142, 144 and 146 comprises a joined area that is defined by the junction pattern. The percentage joined area in a pass region is a measure of the junctions between fibers within the pass region. Specifically, the percentage joined area is determined by calculating the area of the junctions between fibers within a given pass region, dividing said area by the total area in the pass region and multiplying by 100. The joined areas of the pass regions 140 , 142, 144 and 146 may vary. The variability of the number of joined areas between the pass regions 140, 142, 144 and 146 can be determined by comparing a value of the closest area of a pass region with a value of the less bound area of another pass region. A relationship between the most united area and the least united area between two pass regions is known as the junction relationship. In some embodiments, the binding ratio is greater than or equal to about 1 and less than about 20 or any individual number within the range. In other embodiments, the binding ratio is greater than or equal to about 1 and less than or equal to about 10. In other embodiments, the binding ratio is greater than or equal to about 1 and less than or equal to about 3. In some embodiments in which the union relation is 1, there may not be a value of the most united area or the least united area. In this case, the value of a joined area can be divided by the value of another joined area. The sum of the joined areas of each individual pass region can result in the accumulated joined area. The sum of the total areas of each individual pass region can provide the total accumulated area. By dividing the accumulated unit area by the total accumulated area, in some embodiments the total area of joint area 130 can be obtained and, in other embodiments, the total area of receiver component 100.

As illustrated in Figures 2A and 2B, the tie lines, for example, 110 (illustrated in Figure 1 B), 112 and 114, of a receiver component 100 (illustrated in Figure 1) can be obtained in some embodiments by a calendering system 200. The calendering system 200 may comprise a pair of calender rollers 202 and 204 that create a gripping line therebetween. The outer surface of the calender roll 202 or the calender roll 204 may comprise projections (not shown) that extend outwardly from its outer surface. In general, these projections create bonds between fibers in a web of fibrous material 275 as the web of fibrous material 275 passes through the grip line. The receiver component 100 (illustrated in Figures 1A and 1B) may comprise a portion of the web of fibrous material 275. The web of fibrous material 275 may pass through the calender rolls 202 and 204 in a direction generally parallel to the axis longitudinal 160 (illustrated in Figure 1 B) of the receiver component 100 (illustrated in Figures 1A and 1B). Specifically, the longitudinal axis 160 (illustrated in Figure 1B) of the receiver component 100 (illustrated in Figures 1A and 1B) may be, generally, parallel to a machine direction of the calendering system 200. The calender rollers 202 and 204 may rotate in the direction of arrows 280 and 281 (illustrated in Figure 2B), respectively. In some embodiments, calender rolls 202 and 204 can be heated. The calender rollers 202 and 204 can provide energy to the web of fibrous material 275 as the web of fibrous material 275 passes through the nip. In addition, in some embodiments a force 240 can be applied to the calender rolls 202 and 204 in such a way that pressure is applied to the web of fibrous material 275 as it passes through the grip line. The force 240 that can be applied to the calender rolls 202 and 204 is described below.

The contact between surfaces of the calender rolls 202 and 204 can define the contact length 250. The contact length 250 is defined by a portion of the calender roll 202 and a portion of the calender roll 204 which are in contact with the web of fibrous material. 275 (illustrated in Figure 2A) as the web of fibrous material 275 (illustrated in Figure 2A) passes through the grip line. In some embodiments, the contact length 250 can be determined by the hertzian equation included below. The hertzian equation assumes that calender rolls 202 and 204 are made of homogeneous and isotropic material and also assumes the validity of Hooke's law. Other assumptions include that calender rolls 202 and 204 have equal diameters; that the calender rollers 202 and 204 are made of a material having the same elastic modulus; and that the width 220 of the calender rollers 202 and 204 is at least equal to the width 177 (illustrated in Figure 1 B) of the pass regions. The contact length 250 can be obtained by the following equation: where X is half the width of the contact area 250; R is the radius of the calender roller 202 or 204 in millimeters; F is the force applied in Newtons / mm; E is the elastic modulus of the material of the calender rollers 202 and 204; L is the width of the calender rollers 202 and 204 (identified with the number 220); Y u is the Poisson relation. When the calendering rollers do not have equal diameters, an experienced in the industry can derive the above equation taking into account the different diameters of the calendering rollers. When the calendering rollers are not made of materials having equal elastic moduli, one skilled in the industry can derive the above equation by taking into account the different elastic moduli of the calendering rollers. In some modalities, when the calender rolls are made of steel, the elastic modulus E can be equal to 210,000 N / mm2, the Poisson ratio can be 0.3 and the applied force F can be from about 0.03 Nm to about 0.15 Nm (30 N / mm at approximately 150 N / mm). As mentioned above, X is equal to half the contact length 250. Therefore, by multiplying X by two the contact length 250 is obtained. In some embodiments, the contact area 250 can be approximately 0.1 mm at approximately 1.2 mm or any individual number within the range. In some embodiments, the contact area 250 may be from about 0.7 mm to about 1.0 mm. An advantage of the present invention is that due to the relationship between the most bonded area and the least bound area of the present invention the pressure fluctuations during the calendering process can be reduced. For example, when the variation of the junction areas between pass regions of the conventional receiver components is greater than 2000%, the variation of the contact area of the calender rollers that produce these joined areas is also greater than 2000%. Therefore, if the force applied to the calender rolls is constant, the variation of the pressure applied to a web of fibrous material as it passes through the Calendering rolls grip line is also greater than 2000%. In conventional receiver components, pressure fluctuations may be greater than 2000% when some pass regions comprise a 0% area, thus producing an infinite ratio between the most bonded area and the least bound area. The bound zero percent area can occur, for example, when a first junction line and a second junction line are separated by a finite distance in a direction generally parallel to the longitudinal axis of the receiving component that is the same as at least the length from a passing region. In another example, pressure fluctuations greater than 2000% may also occur when there is too much overlap or very little overlap between tie lines. The overlap between tie lines is considered in more detail with respect to Figure 3. With regard to the process, pressure fluctuations greater than 2000% can cause instabilities in it. For example, extreme pressure fluctuations can cause premature failure of the projections on the calender rollers. In terms of product / material performance, pressure fluctuations greater than 2000% are also generally undesirable. For example, a pass region having a 0% area attached may provide low shear capacity and potentially bad results in resilience. Specifically, since a smaller number of loose fiber ends are bonded within this region of passage, it is possible for lint to be detached during multiple opening and closing cycles with suitable coupling components. Also, the pass regions having a 0% area attached can reduce the resistance in a direction parallel to a lateral axis of the receiver component. In some embodiments, the lateral axis of the receptor component may be associated, in many cases, with the direction of shearing. For example, when the receiver component is adjusted, the lateral axis thereof may be generally parallel to the shear direction. For example, with reference to Figure 8A, when the component is fastened, the shearing forces can act along a primary shearing direction 775 which is generally parallel to a lateral axis of a receiving component 740. When there is no overlap between adjacent bond lines, the material of the receptor component between adjacent bond lines is free to move with the applied shear force. In contrast, when it overlaps between tie lines causes pressure fluctuations greater than 2000%, the concentration of bonding sites between fibers in the overlap region will generally result in a low holding capacity. For example, as mentioned above, the coupling components generally can not couple receiving components in the joined areas. In addition, pressure fluctuations greater than 2000% can also produce a variable bonding quality, as previously considered. When the pressure fluctuations are greater than 2000%, the joints between fibers in the pass regions of less bound areas undergo a higher pressure than the pass regions of more joined areas and, that higher pressure, can produce holes. Also, inter-fiber junctions in the pass regions of more joined areas may experience a lower pressure than the pass regions of less bound areas and may produce fewer inter-fiber junctions due to the lower pressure. Specifically, the lower pressure, in some cases, can simply compress the fibers instead of actually joining them. As illustrated in Figure 2C, a receptor component 30 was manufactured in accordance with the present invention and some defects were produced, Examples, 32, 34, 36, 38, 40 and 42. The binding ratio in the receptor component 30 was approximately 1.8. It is believed that when the ratios are approximately 20 or less there may be an acceptable number of defects. Nevertheless, when the binding ratios are greater than 20, an unacceptable amount of defects in a receiving component can occur and, therefore, said relationship may be outside the range of the present invention. In contrast, in the case of conventional receiver components, a receiver component manufactured in accordance with the present invention reduces pressure fluctuations to a percentage less than about 2000%. The reduction in pressure fluctuation, in part, is achieved by ensuring that a binding area of the receptor component comprises a plurality of pass regions which, individually, have a finite number of joined areas. In addition, the pass regions of the receiver components manufactured in accordance with the present invention comprise percentages of bonded areas that reduce pressure fluctuations to a percentage of less than about 2000%. There are several factors that can influence the relationship between the most united area and the least united area. Some factors include the overlap of the lines of union, in some modalities, the angle of orientation of the lines of union, the space of the lines of union and, in some modalities, the orientation of the lines of union during the processing. The orientation of the bond lines during processing is considered in more detail with respect to Figure 6. As illustrated in Figure 3, the overlap 320 is a distance between a first reference line 302 and a second reference line 304 In some embodiments, the overlap 320 is generally parallel to the longitudinal axis 160 and generally parallel to a second direction 1223. In some embodiments, the first line of and reference 302 may be drawn between two more internal points 308 and 310 on the first junction line 110 and may be, generally, parallel to the lateral axis 162. In some embodiments, the second reference line 304 may be drawn between two more internal points 312 and 314 of the second junction line 112 and can generally be parallel to the lateral axis 162. In some embodiments, the innermost points 308 and 310 of the first junction line 110 may be the points closest to the second junction line 112. Similarly, in some embodiments, the innermost points 312 and 314 of the second junction line 112 may be the points closest to the first junction line 110. When the first junction line 110 does not intersect the second line reference 304 and when the second junction line 112 does not intersect the first reference line 302, there is no overlap between the first junction line 110 and the second junction line 112. In addition, Figure 3 illustrates a space 330, an orientation angle 350, a spacing between bond lines 370 and a thickness of the bond line 360. In some embodiments, the space 330 may be the smaller interval after which a periodic function acquires the same values. As illustrated, in some embodiments, the space 330 may be a distance from a first peak 332 of the third junction line 114 to a second peak 334 of the third junction line 114. In embodiments in which the first Union line 110 and second junction line 112 are similar to third junction line 114, space 330 can be identified similarly for first junction line 110 and second junction line 112. An angle is also shown of orientation 350, wherein a portion of the first junction line 110 intersects the first reference line 302. The separation between junction lines 370 is the distance between the first and second junction lines 110 and 112. For example, in some embodiments, the separation between tie lines 370 can be measured from the innermost point 308 of the first line of junction 110 to the outermost point 372 of the second junction line 112. In some embodiments, the outermost point 372 of the second junction line 112 may be the point closest to the third junction line 114. In some embodiments , the spacing between tie lines 370 can be, generally, parallel to the longitudinal axis 160. Any suitable spacing can be used. For example, the spacing 370 between the bond lines may be from about 1 mm to about 20 mm or any individual number within the range. In another example, the spacing 370 may be from about 3 mm to about 18 mm. In another example, the spacing 370 may be from about 6 mm to about 12 mm. Similarly, any suitable joint line thickness 360 may be used. For example, in some embodiments, the thickness of the bond line 360 may be from about 0.2 mm to about 5 mm or any individual number within the range. In some embodiments, the thickness of the bond line 360 may be from about 0.5 mm to about 2 mm. In some embodiments, the thickness of the bond line 360 may be from about 1 mm to about 1.5 mm. Any suitable space 330 can be used with the present invention. For example, in some embodiments, the space 330 may be from about 1 mm to about 20 mm or any individual number within the range. In some embodiments, the space 330 may be from about 1.5 mm to about 15 mm. In some embodiments, the space 330 may be from about 5 mm to about 12 mm. The effect of the overlap of the lines of union in the relation between the most united area and the least united area is illustrated in Table I. Table I contains prophetic examples, and all the calculations contained in Table I are based on a pattern of zigzag joint line similar to the union line pattern illustrated in Figure 1.

Table I.

As shown in Table I and as previously considered (see Example 3), when the overlap of the lines of union is equal to zero, the relationship between the most united area and the least united area can be, in some cases infinite In contrast, in the embodiments of the present invention, the overlap between the first tie line 110 (illustrated in Figure 1) and the second tie line 112 (illustrated in Figure 1) is finite. As shown, see Examples 1 and 4, as the overlap increases, the relationship between the most united area and the least bound area decreases. The thickness of the bond lines can influence the overlap. For example, in Table I, as the thickness of the bond lines decreases, the overlap between the bond lines may decrease in a similar manner (see Examples 1 and 2). In addition, the thickness of all the joining lines in a pattern can be modified as desired to adjust the total percentage of the joined area of the joint pattern. Similarly, the separation of the bond lines can influence the overlap. For example, in Table I, as the separation between the lines of union increases, the overlap between the lines of union decreases (see Examples 1 and 4, 2 and 5). The effect of the orientation angle 350 on the relation between the most united area and the least bound area is illustrated in Table II. Table II contains prophetic examples, and all the calculations contained in Table II are based on a zigzag bond line pattern similar to the bond line pattern illustrated in Figure 1.

Table II. For the examples included above, the orientation angle 350 (illustrated in Figure 3) is changed by a zigzag joining pattern similar to the joining pattern illustrated in Figure 1. As shown, the orientation angle 350 (illustrated in Figure 3) it was modified from about 75 degrees to about 45 degrees and, at the same time, an overlap of about 2.5 mm was maintained for most of the examples. So that in most of the examples the degree of overlap is equal, line separation was also modified for each orientation angle 350 (illustrated in Figure 3). In some examples, the space and thickness of the bond line were kept constant. In Example 6, the orientation angle is 75 degrees, and thus the lowest total percentage of bound area, 20.7%, is obtained in comparison with the other examples in Table II. Without wishing to be limited by theory, it is believed that because the overlap remains constant at about 2.5 mm, this low percentage of bound area is the consequence of the line spacing of 18.7 mm, the line thickness of 1 mm and the 9.3 mm space. As shown in Example 7, with an orientation angle of 65 degrees, while maintaining the overlap to 2.5 mm, the total percentage of bonded area can increase up to 24.1% at a line spacing of 9.8 mm. By reducing the orientation angle of Example 6 by about 10 degrees, the ratio between the most bonded area and the least united area of 1.53 to 1.07 can be reduced. In accordance with the present invention, in some embodiments, the orientation angle 350 may be from about 45 degrees to about 75 degrees or any individual number within the range. In other embodiments, the orientation angle 350 may be from about 55 degrees to about 65 degrees. In other embodiments, the orientation angle 350 may be from about 60 to about 65 degrees. Example 11 illustrates, in a particular embodiment, how it can be done so that the relation between the most bonded area and the least bound area is equal to 1.0 for a zigzag bond line pattern similar to that illustrated in Figure 1. In Some modalities, so that the relationship between the most united area and the least united area is equal to approximately 1.0, the thickness of the union line is adjusted in the areas in which the union lines do not overlap. Based on the parameters and relationships of those parameters considered in the present, the modification of at least one of the parameters or a relation between parameters is contemplated to obtain the relation of approximately 1.0 between the most united area and the least united area. The effect of space on the relationship between the most united area and the least united area is illustrated in Table III. Table III contains prophetic examples, and all the calculations contained in Table III are based on a zigzag junction line pattern similar to the junction line pattern illustrated in Figure 1.

Table III.

At an equal percentage of the total bonded area, the ratio between the most bound area determined and the least bound area is 1.07 for a space equal to about 7. For example 13, the overlap may be about 1.9 mm. Based on the data in Table III, in some embodiments, the space may be from about 5 mm to about 1 1 mm or any number within of the range. In other embodiments, the space may be from about 6 mm to about 8 mm. In other embodiments, the space may be approximately 7 mm. As illustrated in Examples 17-20, the separation of the bond line can be adjusted so as to influence the total bound area. In some embodiments of the present invention, the total joined area may be from about 10% to about 50% or any individual number within the range. In other embodiments, the total percentage of the bound area may be from about 20% to about 30%. In other embodiments, the total percentage of the bound area may be from about 20% to about 25%. In other embodiments, the total bonded area may be less than about 40% while the bonded area in any pass region is less than about 60%. In other embodiments, the total bonded area may be less than about 30% while the bonded area in any pass region may be less than about 50%. In other embodiments, the total bonded area may be from about 20% to about 30% while the bonded area in any pass region is less than about 40%. As mentioned above, the data in Tables I, II and III are based on zigzag bond line patterns similar to the bond line pattern illustrated in Figure 1. However, an industry expert can calculate the values of the parameters listed in Tables I, II and III for any given joint line pattern or variations thereof. For simple geometries, for example, which consist of straight, angulated and connected lines, the values illustrated in Tables I, II and III can be calculated using the geometric and trigonometric relationships of the straight and angled straight lines, as is done for the patterns of union line illustrated previously. For more complex patterns, for example, those illustrated in Figures 4A-4C or tie line patterns including shapes such as the shapes of Figures 5B-5E, the values of Tables I, II and III can be obtained by analysis of computer image. In computerized image analysis, the binding pattern in question is digitized in such a way that a color contrast can be measured reliably to determine the locations of the joined and unattached areas. For example, the unattached areas may be represented by white pixels and the areas joined by black pixels. To determine the percentage of the bound area, the number of pixels representing a bound area can be calculated and compared to the number of pixels representing an unattached area. Similarly, space, overlap, joint line thickness, orientation angle, and line separation can also be measured by computerized image analysis. In addition, any data or trend considered with respect to Tables I, II and III is applicable to the analyzed union line patterns, for example, zigzag pattern. Consequently, any data or trend considered with respect to Tables I, II and III may be invalid for other tie line patterns. As illustrated in Figures 4A-4C, the overlap between adjacent tie lines can be obtained in several different ways. For example, as illustrated in Figure 4A, a receiver component 400A made in accordance with the present invention may comprise a first junction line 41 OA and a second junction line 412A. The first junction line 41 OA and the second junction line 412A may individually comprise a plurality of repeating units 51 OA. In some embodiments, the repeating units 51 OA of the first junction line 41 OA and the second junction line 412A may overlap one another by extensions 520 which generally extend in a direction parallel to longitudinal axis 160 from each repeating unit 51 OA. Also, as illustrated, in some embodiments, the first and second joining lines 41 OA and 412B may comprise extensions 520 extending in a direction generally parallel to the longitudinal axis 160 between repeating units 51 OA. In some embodiments, the extensions 520 may extend at an angle with respect to the longitudinal axis 160. In some embodiments, the extension angle 1350 (illustrated in Figure 4C) may be greater than about 0 degrees to less than about 180 degrees or any individual number within the range. In other embodiments, the extension angle 1350 (illustrated in Figure 4C) may be from about 30 degrees to about 150 degrees or less. In still other embodiments, the extension angle 1350 may be from about 60 degrees to about 120 degrees. In some embodiments, the extension angle 1350 of all tie lines may be similar. In some embodiments, the extension angle 1350 may vary between the joining lines of a joining pattern. In addition, in some embodiments, the extension angle 1350 may vary between repeating units 510A. In other embodiments, as illustrated in Figure 4B, a receiver component 400B manufactured in accordance with the present invention may comprise a first link line 410B and a second link line 412B. Similarly, the first junction line 410B and the second junction line 412B can comprise a plurality of repeating units 510B having extensions 520. The extensions 520 of the repeating units 510B can be configured similarly to extensions 520 of the repeating units 510A. In addition, as illustrated in Figure 4B, the bond lines of the present invention are not limited to rectilinear repeat units 510A. For example, as illustrated, in some embodiments, the connecting lines they may comprise a plurality of repeating units 51 OB comprising curvilinear segments. As illustrated, the repeating units 51 OB have a sinusoidal shape. Some examples of other repeating units are illustrated in Figures 5A-5E. In some embodiments, the extensions 520 of Figures 4A and 4B may be, as illustrated, straight lines. However, the extensions may comprise any suitable form. For example, in some embodiments, the extensions 520 may comprise the shapes of rectangles, circles, triangles, rhomboid structures, trapezoidal structures, any suitable polygonal shape, curvilinear lines, angled lines, serpentine lines, combinations thereof, or the like. In other embodiments, the extensions 520 may comprise aesthetic designs, for example, a graphic or children's graphics. The graph can be any suitable image or visual images. The graphic may include pictorial symbols or images that include, but are not limited to, photographs, drawings, prints or any other suitable material used to create pictorial symbols or images. The pictorial symbols or images can include an image of a child, an anthropomorphic image of an animal or object, images of cartoons that include characters from well-known cartoons, images of logos of well-known brands or similar or images of characters created especially for associate them with the commercial implement, symbols that include, but are not limited to, arrows, indications or movement, and the like, and combinations of these. Children's graphics and charts are considered in U.S. Patent Publication. no. 2005 / 0129743A1, U.S. Patent Publication. no. 2005 / 0125923A1 and U.S. Patent Publication. no. 2005 / 0125877A1. It has been found that in some embodiments pass regions comprising portions of more than one junction line may have joined areas greater than the pass regions comprising a portion of a single junction line. The bonded area of the pass regions comprising portions of more than one junction line can be reduced by any suitable means. For example, as illustrated in Figure 4D, the first link line 10 or the second link 112 may comprise a plurality of link sites 460 which, in some embodiments, may approximate a line. The plurality of attachment sites 460 may be located in the overlap 320 between the first junction line 110 and the second junction line 1 12. In some embodiments, the plurality of junction sites 460 within the overlap 320 may define an area less united, than a continuous bond line in the overlap, thereby reducing the amount of joined area in the overlap 320. The plurality of bonding sites 460 may comprise any suitable form known in the industry. As illustrated in Figure 5A, a receiver component made in accordance with the present invention may comprise a junction line that includes a plurality of repeating units 510A. In some embodiments, the repeating unit 510A may comprise an open geometric shape comprising rectilinear lines forming a first leg 517 and a second leg 519 of the repeating unit 510A. As illustrated in Figure 5B, in some embodiments, the repeating unit 51 OA may comprise rounded edges 529 connecting the first leg 517 and the second leg 519 of the repeater unit 51 OA. The rounded edges 529 may be located in a similar manner between adjacent repeating units. As illustrated in Figure 5C, the repeating unit 51 OA may comprise flat edges 530 connecting the first leg 517 to the second leg 519 of the repeater unit 51 OA. The flat edges 530 may be located in a similar manner between adjacent repeating units. As illustrated in Figure 5D, in some embodiments, the repeating unit 51 OA may comprise a plurality of corrugated edges 512 and 514 that define the limit for the first leg 517 and the second leg 519. In embodiments in which the tie lines comprise a plurality of repeat units with corrugated edges, the thickness of the joint line can be determined by measuring the thickness of the repeat unit 51 OA in at least 10 places and determining, from there, the average thickness. Furthermore, as illustrated in Figure 5E, in some embodiments, the repeating unit 51 OB may comprise a plurality of sinusoidal shaped edges 516 and 518. The repeating units 51 OA and 51 OB of the present invention may comprise any form or combination of appropriate forms. In some embodiments, a tie line of the present invention may comprise different repeat units within the tie line. In other embodiments, the repeating units in a first junction line may be similar while a second junction line comprises a repetition unit different from the repetition units in the first junction line. As mentioned above, the orientation of the junction lines during processing can also affect the relationship between the most united area and the least bound area. In a receiver component made in accordance with the present invention, a longitudinal axis of the receiver component can generally be parallel to a machine direction during processing. In some embodiments, the resulting tie lines may extend from the first longitudinal edge 170 (illustrated in Figures 1 B and 3) to a second longitudinal edge 172 (illustrated in Figures 1 B and 3). In contrast, as illustrated in Figure 6, in some embodiments, a receiver component 1000 made in accordance with the present invention may comprise a first link line 1010, a second link line 1012 and a third link line 1014. In some modalities, the first line of union 1010, the second junction line 1012 and third junction line 1014 may extend from a first terminal edge 1151 to a second terminal edge 1152 of receiver component 1000 in a first direction 1224 that is generally parallel to a longitudinal axis 1060. Receiving component 1000 may comprising a junction zone 1030 circumscribing a junction line closest to a first longitudinal edge 1 170 and a junction line closest to a second longitudinal edge 1172 and any junction line therebetween. For example, as illustrated, the junction zone 1030 may circumscribe the first lines of junctions 1010, the second junction line 1012 and the third junction line 1014. Modes are contemplated in which the receiver component comprises more than three junction lines. union and less than three union lines. The junction zone 1030 comprises a plurality of pass regions 1040, 1042, 1044, 1046, 1048, 1050 and 1052. The plurality of pass regions 1040, 1042, 1044, 1046, 1048, 1050 and 1052 may comprise lengths and widths similar to the pass regions considered above. As illustrated, in some embodiments, each pass region of the plurality of pass regions 1040, 1042, 1044, 1046, 1048, 1050 and 1052 may comprise a portion of the first junction line 1010, a portion of the second line of junction 1012 and a portion of the third junction line 1014. Similar to the pattern of the junction line illustrated in Figure 1 B, in the pattern of the junction line of Figure 6, each pass region has a finite amount of united areas. The first link line 1010 can overlap the second link line 1012 and the second link line 1012 can overlap the third link line 1014. However, as opposed to the overlap 320 (illustrated in Figure 3) of the receiver component 100 (illustrated in Figures 1 and 3), the overlap 1020 of the receiver component 1000 can be generally parallel to the axis 1062. Similarly, the second joining line 1012 can overlap the third joining line 1014. The overlap 1020 can be the distance between a third reference line 1565 and a fourth reference line 1575. In some embodiments, the overlap 1020 may be, generally, parallel to a second direction 1225. In some embodiments, the third reference line 1565 may be, generally, parallel to the longitudinal axis 1060. Similarly, in some embodiments, the fourth reference line 1575 it may be, generally, parallel to the longitudinal axis 1060. The third reference line 1565 may extend from the first terminal edge 1151 to the second terminal edge 1152 and may intersect the innermost points of the first junction line 1010. The innermost points of the first junction line 1010 are those points that are closer to the second junction line 1012. The fourth reference line 575 can extending from the first terminal edge 1151 to the second terminal edge 1152 and may intersect the outermost points of the second joining line 1012. With reference to the overlap 1020 between the first junction line 1010 and the second junction line 1012, the points The outermost of the second junction line 1012 are those points of the second junction line 1012 that are closer to the first junction line 1010. A receiving component of the present invention can be configured in several different ways. For example, in some embodiments, the receiving component may comprise a web of fibrous material, such as a woven web, a web of non-woven web or any combination thereof. In some embodiments, the process described with respect to Figures 2A and 2B can be used to create joins between loose fibers of a non-woven fabric, thereby creating a web of non-woven fabric. In other embodiments, the process can be used to provide a supplementary bond to a nonwoven fabric web that is already slightly bonded. Also, in In some embodiments, the supplementary connection can join the non-woven fabric web to a support structure. For example, the nonwoven fabric web can have an initial bonded area of about 10% to about 20% and, subsequently, can be attached to a backing layer using the bonding patterns of the present invention. The resulting receiver component can have a larger area than the initial joined area. The support layer may comprise any suitable support layer known in the industry. For example, the support layer may include films or non-woven fabric webs. Modalities are contemplated in which the receptor component is attached to a disposable absorbent article by the bonding patterns of the present invention. For example, the receiving component may be attached to a lower canvas of a disposable diaper. An advantage of attaching a receptor component to an underlying support layer using the binding patterns of the present invention is that, in some embodiments, no adhesive is required. For example, in certain embodiments, when a calendering system is used as described with respect to Figures 2A and 2B, the bonding pattern of the present invention can be used to join a receptor component and a backing layer without adhesive. In certain embodiments, the initial joined area of a receiver component may not be measurable. Specifically, in embodiments in which the receiving component comprises a web of non-woven fabric having hydroentangled or punched fibers, an initial bonded area may not be determined. However, these nonwoven webs can be used in a receptor component and can be attached to underlying support layers by the binding patterns of the present invention.

As mentioned above, a receiver component manufactured in accordance with the present invention may comprise a nonwoven fabric web. In some embodiments, the nonwoven fabric web may comprise a fiber layer. In other embodiments, the nonwoven fabric web may comprise more than one layer of fibers. Any suitable nonwoven fabric weave can be used. For example, a suitable nonwoven fabric may comprise fibers made of polypropylene, polyethylene, polyester, nylon, cellulose, polyamide or combinations of such materials. The fibers of a material or the fibers of different materials or combinations of materials may be used in the first or second non-woven fabric. Illustrative nonwoven fabric materials include spunbond, spunbond-spunbond-spunbond (SMS), spunbond-spunbond-meltblown-spunbond (SMMS), carded, cast by blown and the like. Especially acceptable non-woven fabrics include high-stretch carded non-woven fabrics (HEC) and deep-activated polypropylene non-woven fabrics (DAPP). Any process known in the industry can be used to manufacture the non-woven fabrics. The non-woven fabric may comprise fibers that are mechanically bonded, including fibers that are needle punched or hydroentangled. Other bonding processes suitable for producing a nonwoven fabric for use in the present invention are spunbonding, thermobonding, bonding by various types of chemical bonding, such as latex bonding, with powder and the like. In certain embodiments, the basis weight of the non-woven fabric may be in the range of about 10 g / m2 to about 100 g / m2 or any individual number within the range. In other embodiments, the basis weight of the non-woven fabric may be in the range of about 25 g / m2 to about 80 g / m2. In still other embodiments, the basis weight of the non-woven fabric may be in the range of about 30 g / m2 to about 50 g / m2. The fibers may be of any suitable size and shape. Some examples of suitable cross-section shapes include circular shape, elliptical (with or without extensions with lobe shape), rectangular, triangular, rhomboid, trapezoidal, any polygon or similar. In addition, in some embodiments, the cross-sectional shape may include a plurality of lobes. For example, a cross sectional shape may include three lobes, that is, it may be trilobed. Modes are contemplated that have more than three lobes and less than three lobes. In some embodiments, the fibers may be hollow. For example, the fibers may be hollow crimped fibers. The fiber can be any suitable denier. For example, in some embodiments, the fiber may have a denier of about 1 to about 10 or any individual number within the range. In some embodiments, the denier of the fibers may range from about 1 to about 8. In other embodiments, the denier of the fibers may range from about 1 to about 5. In addition, in some embodiments, the non-woven fabric webs of the present invention may comprise fibers made of polypropylene, polyethylene, polyolefins, bicomponent fibers or any combination thereof. In addition, the crimped composite fiber (hereinafter referred to simply as a composite fiber or a laminate of nonwoven fabric made therefrom) can be used in accordance with the present invention. The crimped composite fiber may comprise a first propylene polymer and a second propylene polymer. The first and the second propylene polymer can be arranged to occupy practically separate areas in the cross sections of the composite fibers and to extend continuously in the length direction. In some modalities, the first and second propylene polymer, individually, form at least a part of the peripheral surface along the length direction of the composite fiber. In some embodiments, as illustrated in Figure 9A, a composite fiber 1500 may be a composite fiber of the parallel type, wherein a first propylene polymer 1502 and a second propylene polymer 1510 extend parallel in the length direction of the composite fiber. , such that each propylene polymer, first 1502 and second 1510, forms about 50% of a peripheral surface 1520 of the composite fiber 1500. The first propylene polymer 1502 and the second propylene polymer 1510 can be arranged in any suitable configuration with the which is obtained a curl in the resulting fiber 1500. For example, in some embodiments, as illustrated in Figure 9B, the second propylene polymer 1510 may form a cross-type pattern within the first propylene polymer 1502 which is distributed asymmetrically within the first propylene polymer. In some embodiments, as illustrated in Figure 9C, the second propylene polymer 1510 may be completely surrounded by the first propylene polymer 1502, such that the first propylene polymer 1502 comprises approximately 100% of the peripheral surface 1520 of the composite fiber. 1500. The second propylene polymer 1510 may be distributed asymmetrically within the first propylene polymer 1502 in such a way that a curl is obtained in the resulting fiber 1500. In some embodiments, the first propylene polymer 1502 and the second propylene polymer 1510 may be in a parallel orientation such that an opening 1530 is formed between the first propylene polymer and the second propylene polymer. This configuration can be similar to a hollow fiber. In addition, modalities are contemplated in which the second polymer propylene 1510 comprises any percentage greater than about 50% of the peripheral surface 1520 of the composite fiber 1500. In addition, embodiments are contemplated in which the second propylene polymer 1510 comprises any percentage less than about 50% of the peripheral surface 1520 of the fiber Composite 1500. Likewise, the first propylene polymer 1502 may be configured similarly to the second propylene polymer 1510 and vice versa. Modes are contemplated in which the fibers are crimped in such a way that they form loops or helical structures. In some embodiments, the melting point of the first propylene polymer 1502 as measured by differential scanning calorimetry (DSC) can be at least 15 ° C higher than the melting point of the second propylene polymer 1510. In some embodiments, the melting point of the The first propylene polymer 1502 may be from about 15 degrees C to about 60 degrees C, or any number within the range, greater than the melting point of the second propylene polymer 1510. In addition, in some embodiments, the weight ratio measured between the first propylene polymer 1502 and the second propylene polymer 1510 may be from about 50/50 to about 5/95 or any ratio within the range. In some embodiments, the weight ratio can be from about 40/60 to about 10/90 or any ratio within the range. In some embodiments, the weight ratio can be from about 30/70 to about 10/90 or any ratio within the range. In some embodiments, a method that can be used to determine the weight ratio between the first propylene polymer 1502 and the second propylene polymer 1510 can be fractionation by elution with temperature increase (TREF). For example, weight relationships can be determined using a T-150A cross-fractionation chromatograph manufactured by Mitsubishi Chemicals Corporation; an infrared spectrometer 1 ACVF 3.42 micrometers at 135 degrees C manufactured by Miran; and a TREF column with an inner diameter of 4 mm and a length of 150 mm. Other steps may include the use of an o-dichlorobenzene eluent (ODCB) at a flow rate of 1.0 ml / min, a sample concentration of 30 mg / 10 ml-ODCB and a sample volume of 500 microliters. Other conditions may include cooling the sample from 135 degrees C to 0 degrees C in 135 minutes then maintaining the sample at 0 degrees C for 60 minutes. The fractionation steps may include 0, 20, 40, 50, 60, 75, 80, 83, 86, 89, 92, 95, 98, 101, 104, 106, 108, 11, 12, 14, 1 16, 1 18, 120, 122, 125, 130 and 135 degrees C. A resulting elution curve can be divided with a perpendicular line (perpendicular to the x axis) in a valley between two peaks. The perpendicular line can create a first portion and a second portion of the elution curve. The first portion may comprise the area under the curve to the right of the perpendicular line while the second portion may comprise the area below the curve to the left of the perpendicular line. The weight ratio between the first propylene polymer and the second propylene polymer can be calculated as a function of the ratio between the first portion and the second portion. In some embodiments, the melt-fluid index (MFR) of the first and second propylene polymer measured in accordance with the specification of ASTM D1238 (MFR: measurement temperature 230 ° C, load 2.16 kg) (second propylene polymer / first propylene polymer) can be from about 0.8 to about 1.2 or any individual number within the range. In some embodiments, the melt flow rate may be about 0.9 to approximately 1.1. In some embodiments, the area ratio between the first propylene polymer and the second propylene polymer in the cross section of the composite fiber may be approximately the same as the weight ratio. For example, in some embodiments, a ratio between the cross-sectional area of the first propylene polymer and the cross-sectional area of the second propylene polymer may be from about 50/50 to about 5/95 or any ratio within the range. In some embodiments, the ratio may be from about 40/60 to about 10/90 or any ratio within the range.

The longitudinal edges 675A and 675B may extend, generally, parallel to a longitudinal centerline 690 of the disposable absorbent article 600 The first waist edge 650 and the second waist edge 651 may extend, in general, p rails to a lateral center line 680 of the disposable absorbent article 600. The disposable absorbent article 600 may also comprise leg elastics 631 which may be located adjacent the longitudinal edges 675A and 675B. The disposable absorbent article 600 may also comprise a first waist member 602 and a second waist member 604. The first waist member 602 or the second waist member 604 may be elastically extensible. As illustrated, in some modalities, the first waist member 602 may be disposed adjacent the first waist edge 650. In some embodiments, the second waist member 604 may be disposed adjacent the second waist edge 651. Generally, the first waist member 602 or the second waist member 604 they can be under tension before joining them to the disposable absorbent article 600. Thus, when at least a portion of the tension applied to the first waist member 602 or the second waist member 604 is released, a portion of the disposable absorbent article 600 attached to these can be undulated. This waviness of the disposable absorbent article 600 may allow the first waist member 602 or the second waist member 604 and the disposable absorbent article 600 to expand and contract around a wearer's waist, thus providing more comfort and better fit to the wearer. user. Some examples of suitable waist members 602 and / or 604 include those described in U.S. Pat. no. No. 4,515,595, U.S. Pat. no. 5,151, 092 and U.S. Pat. no. 5,221, 274. Although disposable diapers are generally made to have two waist elastics, one in the first region and the other in the second region, the diapers can be manufactured with a single waist elastic. The disposable absorbent article 600 may also comprise external folds 632 and internal folds 652 to improve containment of liquids and other body exudates. Each elasticated external fold 632 may include several different embodiments to reduce leakage of body exudates into the leg regions.

Alternatively, in some embodiments, the disposable absorbent article 600 may comprise a pair of side panels that are located in the second region of waist 638 and a pair of side panels that are located in the first waist region 636. In some embodiments, the side panels 628 may form a portion of the leg openings when the disposable absorbent article 600 is adjusted. The side panels 628 can form a portion of the leg openings that would be placed on an outer surface of a user's leg. A crotch region 610 of the disposable absorbent article 600 together with the first waist region 636 and the second waist region 638 may form a portion of the leg openings, which would be disposed on an inner surface of the wearer's leg. In some embodiments, the side panels 628 may be elastically extensible. The disposable absorbent article 600 further comprises a fastening system 640 that joins at least a portion of a first waist region 636 with at least a portion of a second waist region 638, preferably to form the leg openings and for the waist. The fastening system 640 also works with the waist member (s) 602 or 604 to maintain lateral tension in order to hold the disposable absorbent article 600 in place around the wearer's waist. The fastening system 640 may comprise coupling components 642 which, in some embodiments, may be located in the side panels 628. The fastening system 640 may comprise also a receiver component 644 which, in some embodiments, is located in the first waist region 636. As illustrated in Figure 7C, in other embodiments, the fastening system may include a plurality of fastening components in the side panels 628 For example, as illustrated, the side panel 628 may comprise the coupling component 642 which, in some embodiments, may include a plurality of coupling elements. In addition, in some embodiments, the side panel 628 may also comprise a receiver component 1475 positioned opposite the coupling component 642. An advantage of this arrangement is that the coupling component 642 may be coupled to the receiver component 644 (illustrated in FIG. Figure 7A) that is attached to the first waist region 636 or can be attached to the receiver component 1475 of the other side panel 628. As illustrated in Figure 7A, the receiving component 644 is located in the disposable absorbent article 600 in such a way that the overlap of the bond lines 1375 is generally perpendicular to the primary shear direction 775. As illustrated in Figure 7A, the primary shear direction 775 is an expected force during use that generally occurs once that the disposable absorbent article 600 is adjusted. In some embodiments, the receiver component 644 may be located adjacent the first waist edge 650 in the first waist region 636 on a surface of the disposable absorbent article 600 facing outwardly. In other embodiments, the receiver component 644 may be located adjacent the second waist edge 651 in the second waist region 638.

In some embodiments , the receiver components 644 may be located in the side panels 628 and the coupling component may be located in the first waist region 636. In some embodiments, the receiving component 644 may comprise a plurality of distinct elements. Any suitable coupling element 642 can be used in the present invention. An example of a suitable coupling element 642 comprises a hook fastening material. The hook fastener material can mechanically engage fibrous elements of the receiving element 644 to provide a secure closure. A hook fastening material, in accordance with the present invention, can be manufactured from a wide range of materials. The materials include nylon, polyester, polypropylene or any combination of these or other materials as known in the industry. A suitable hook fastener material comprises several coupling elements projecting from a base, such as the material commercially available under the name of Scotchmate ™ N °. FJ3402, distributed by Minnesota Mining and Manufacturing Company of St. Paul, Minn., Alternatively, the coupling elements can take any form, such as hook, "T", mushroom or any other form, as is known in the industry. . An illustrative hook fastener material is that described in U.S. Pat. no. 4,846,815. Another hook fastener material comprises an arrangement of tines formed of thermoplastic material. Hot melt thermoplastic adhesives, in particular hot melt adhesives made of polyester and polyamide, are particularly suitable adhesives for forming the tips of the hook fastener material. In some embodiments, the tines can be manufactured using a modified rotogravure printing process by printing the thermoplastic material when it is cast on a substrate in different units, cutting the material in such a way as to allow stretching of a portion of the thermoplastic material before cutting. , and letting the material melt stretched "freeze" to produce the tines. This hook fastener material and the methods and apparatus for manufacturing such hook fastener material are developed in detail in European Patent Application no. 0 381 087. The fastening system 640 may be the primary fastening system for joining the first and second waist regions 636 and 638. However, the fastening system 640 may be used alone or together with other fastening means, such as fasteners of tongue and groove, tape fasteners, snaps, buttons, and the like, to offer different fastening characteristics. For example, the fastening system 640 may provide the disposable absorbent article 600 with a means for disposing of the article 600 that holds it in a suitable configuration for disposal. In addition, the secondary fastener means may provide the disposable absorbent article 600 with a means for adjusting the fit or may increase the strength of the connection between the first waist region 636 and the second waist region 638. The fastening system 640 may be presumed in a container, such that the caregiver or the user can pull the disposable absorbent article 600 out of the container. Alternatively, the fastening system 640 may be peeled off in the package, such that the caregiver or the user adjusts the fastening system 640 while placing the disposable absorbent article 600. In yet another embodiment, a package may comprise disposable absorbent articles 600. presujetados and detached for the convenience of the carer or the user. Figure 8A illustrates a disposable absorbent article 700 comprising a fastening system 740. The fastening system 740 comprises a first coupling component 760A located in a first side panel 728A and a second coupling component 760B located in a second side panel 728B .

The first coupling component 760A and the second coupling component 760B can be coupled to the receiver component 644 when adjusting them. The receiver component 644 may comprise a plurality of tie lines 718 created in accordance with the present invention. Each plurality of tie lines 718 may comprise ridges and valleys. As mentioned earlier, the receiving component 644 may be located in the disposable absorbent article 700 such that the overlap between the bond lines is generally perpendicular to the primary shearing direction 775. Therefore, the receiving components of the present invention are manufactured in a manner similar to the receiver component 100 (illustrated in Figures 1 B and 3) may be located in the disposable absorbent article 700 such that the lateral axis 162 (illustrated in Figures 1 B and 3) of the receiving component is generally parallel to the primary shearing direction 775. Alternatively, the receiving components of the present invention fabricated similarly to the receiving component 1000 (illustrated in Figure 6) may be located in the disposable absorbent article 700 such that the longitudinal axis 1060 of the receiving component is generally parallel to the primary direction of shearing 775. The primary direction Shear 775 is defined by forces during use. Specifically, when the disposable absorbent article 700 is fastened, the first side panel 728A and the second side panel 728B exert a force on the receiver component 644. The force may be caused, in part, by the elastomeric material of the side panels, if these are elastically extensible. In addition, the user or caregiver can produce the shearing forces during the placement of the disposable absorbent article 700. Figure 8B illustrates a disposable absorbent article 702 comprising a fastening system 740. Similar to the previous disposable absorbent article, the the first coupling component 760A and the second coupling component 760B can be coupled to the receiver component 644 when they are fastened. The receiver component 644 may comprise a first plurality of tie lines 722 and a second plurality of tie lines 720. A portion of each first plurality of tie lines 722 overlaps a portion of each adjacent tie line. Similarly, a portion of each second plurality of tie lines 720 overlaps a portion of each adjacent tie line. The first plurality of connecting lines 722 may be at such an angle as to provide a user with a visual indication of the location at which the first coupling component 760A is to be adjusted. In addition, the second plurality of connecting lines 720 may be at an angle such as to provide a user with a visual signal of the location at which the second coupling component 760B is to be adjusted. In some embodiments, the holding angles 1250 may be from about 0 degrees to about 45 degrees or any individual number within that range. In other embodiments, the clamping angle 1250 may be from about l or degrees to about 25 degrees. In other embodiments, the clamping angle 1250 may be from about 15 degrees to about 20 degrees. The clamping angle 1250 of the first plurality of tie lines 722 can be determined by straight line approximations for each joint line within the joint pattern of the first plurality of tie lines 722. A tie line can be considered as a part of the first plurality of junction lines 722 when a portion of that junction line overlaps some portion of another junction line within the first plurality of junction lines 722. The straight line approximations for each junction line within the first plurality of union lines 722 they can be averaged to determine a first orientation line 1253 for the first plurality of attachment lines 722. The intersection between the first orientation line 1253 and a longitudinal axis 770 of the disposable absorbent article 702 defines the attachment angle 1250. The same analysis can performed for the second plurality of tie lines 720. Disposable absorbent articles may comprise many components, elements, members, etc. and they can be manufactured in various ways. For example, the upper canvas 622 (illustrated in Figure 6) and the lower canvas 624 (illustrated in Figure 6) may have a length and width generally greater than those of the absorbent core 626 (illustrated in Figure 6). Upper canvas 622 (illustrated in Figure 6) and lower canvas 624 (illustrated in Figure 6) can extend beyond the edges of absorbent core 626 (illustrated in Figure 6), thus forming the periphery of the disposable absorbent article. 600 (illustrated in Figure 6).

The lower canvas or any portion thereof may be elastically extensible in one or more directions. In one embodiment, the lower canvas may comprise an elastic structural film ("SELF") frame. An elastic structural film web is an extensible material that exhibits an elastic-like behavior in the direction of elongation without the use of additional elastic materials and is described in more detail in U.S. Pat. no. 5,518,801. In alternate embodiments, the lower canvas may comprise elastic films, foams, strands or combinations of these or other suitable materials with non-woven fabrics, or synthetic films. An absorbent core suitable for use in the present invention may comprise any absorbent material that is generally compressible, conformable, that does not irritate the user's skin and is capable of absorbing and retaining liquids, such as urine and other body exudates. . In addition, the configuration and construction of the absorbent core can also be varied (eg, the absorbent core (s) may have gauge zones variable, hydrophilic gradients, super absorbent gradients, or acquisition zones of lower average density or lower average basis weight; or may comprise one or more layers or structures). Illustrative absorbent structures suitable for use as an absorbent core are described in U.S. Pat. num. 4,610,678, 4,673,402, 4,834,735, 4,888,231, 5,137,537, 5,147,345, 5,342,338, 5,260,345, 5,387,207 and 5,625,222.

Test methods: Determination of the bound area of a receptor component: Sample Preparation 1. Sufficient absorbent articles representative of the retail packing of the absorbent article are selected to perform all required tests. The receiving components of each absorbent article are removed from the articles. Suitable methods include cutting the receptor components to separate them from the articles. 2. Allow each sample to equilibrate in a controlled environment. The environmental parameters are: 22 degrees C ± 2 degrees C, 50% relative humidity ± 10% relative humidity. Samples are placed in these conditions at least 24 hours before the test. 3. A sample is secured to a flat surface. The sample is secured to the flat surface in such a way that the sample is completely located on the flat surface. The sample is secured to the flat surface with a tape, such as the Scotch Removable Magic Tape ™ tape manufactured by 3 ™. 4. The joint zone is identified in accordance with the description of the joint zone included herein. 5. Pass regions within the junction zone are identified in accordance with the description of the pass regions included herein. Each pass region has a length equal to the contact area between the calendering rollers. Each pass region has a width equal to the width of the frame with which the receiver component is manufactured. When the measurement of the area of contact between calender rollers, the length of the contact zone is divided by 0.25 and rounded to the nearest whole number. The quotient is the number of pass regions within the junction zone. The regions of pass have the same length. The united area within each pass region is measured and the joined areas of the pass region are recorded as Bi, where i = 1 to n where n is the total number of pass regions. The bonded area is measured to the nearest 0.01 mm2. The total area of each pass region is measured and the total area of the pass region Si is recorded, where i = 1 to n where n is the total number of pass regions. The total area is measured to the nearest 0.01 mm2. From the collected data, it is calculated: a) The union relation: i) The pass region that has the least united area is identified and registered as Bi, min. ii) The pass region with the most united area is identified and registered as Bi, max. iii) The binding ratio = Bi, max / Bi, min. b)% of area joined in each pass region: i) Percentage of area joined for each pass region = 100 * Bi / Si. c) Total% of united area: i) The accumulated unit area is calculated, Bt = sum of Bi, in where i = 1 to n. i) Calculate the total accumulated area, St = sum of Si, where i = 1 to n. Ii) Total percentage of united area = 100 * Bt / St. As mentioned above, the areas can be measured using straight line measurements and geometric / trigonometric relationships. Alternatively, computerized image analysis can be used for patterns of more complex bond lines.

Determination of the amount of curls in a fiber: The amount of curls was measured in accordance with the procedure explained below. It should be mentioned that with the exception of the procedure indicated below, the measurements were made in accordance with the specification of JIS L1015. First, lines with a spatial separation of 25 mm were formed on a glossy paper with a uniform surface. The two ends of each fiber were carefully removed from the non-woven fabric before thermal compression treatment with an engraving roller in such a way that the curls were not deformed and were applied on the paper mentioned above with a relaxation of 25 ± 5% for spatial separation. Each test piece mentioned above was applied to the plate of the curling test instrument, and after removing the paper the distance between plates (spatial distance) (mm) during the initial load (0.18 mN x tex number shown) was verified. The number of existing curls was counted, the number of curls was determined by distance of 25 mm and the mean value was used 20 times. To determine the number of curls, the total of peaks and valleys was counted and divided by 2.
