Description

Items with fasteners

This creation relates to an article having a face fastener, and more particularly to an article having a face fastener comprising male and female mold portions that can contact each other face to face.

Japanese Patent Application Publication No. 2007-44139 discloses a mold portion for a so-called face fastener, revealing that by using features related to size ratio and density (see technical solution 1 of the document), various problems (one of which is suppressing pilling of underwear) can be solved when attaching absorbent materials to underwear.

Japanese Patent Application Publication No. 2004-522538 also relates to a male mold portion of a face fastener, disclosing that the male mold portion of the face fastener is gentle on the skin by means of features related to aspect ratio (see technical solution 1 of that application). That application discloses that the bristles are manufactured from a polymer with a volumetric flexural modulus of 48 MPa to 207 MPa (see paragraph 0063, technical solution 4 of that application).

[Problem to be Solved in the Creation] When fasteners are installed on an item by sewing, the male mold part may unintentionally come into contact with a napped surface of the item's constituent material other than the female mold part (e.g., the surface of the fabric around the female mold part). If this contact is repeated many times (e.g., dozens, hundreds, or thousands of times), it may cause the surface of the item's constituent material to become napped, and the male mold fitting element may become stuck in the napped thread (also known as filament), thus damaging the appearance of the item's constituent material.

Furthermore, the design premise of the male mold part is for repeated snapping with the female mold part. Therefore, it is not possible to specifically design the male mold engagement element to suppress the fuzzing of the surface of the material.

As explained above, it is essential to ensure the reliable engagement of the female mold and male mold parts, while also preventing the male mold part from unintentionally contacting areas of the item prone to pilling, which could lead to pilling. [Technical Solutions]

The creator of this work conducted in-depth research on the above phenomenon and found that one of the reasons was that the threads (also known as filaments) on the napped surface of the material of the item were knocked and loosened by the mold-fitting components, which led to the following creation.

The invention comprises an article having a male mold and a female mold portion and at least one article constituent material, wherein the male mold and female mold portion are fixed to different positions on the article in a manner that allows them to contact each other, and the at least one article constituent material has a napped area that the male mold portion can at least partially abut against, and the male mold portion includes a group of male mold engaging elements, which are arranged in a two-dimensional manner and include two or more male mold engaging elements that each have a top surface that can abut against the napped area, and each of the group of male mold engaging elements or the two or more male mold engaging elements comprises the same polymer material, which has a flexural modulus of 800 MPa or less, or 500 MPa or less, or 450 MPa or less.

In several embodiments, the aforementioned master mold portion comprises a group of coils formed by inverting individual coils as a group of master mold engaging elements, forming a woven or knitted structure in the aforementioned napped area, wherein each unit structure of the woven or knitted structure is tilted. The woven or knitted structure may comprise a pile group formed by two-dimensionally arranged pile ends. The maximum number of unit structures that each of the aforementioned top surfaces can abut may be 9 or less, 7 or less, or 5 or less. The minimum number of unit structures that each of the aforementioned top surfaces can abut may be 2 or more, or 3 or more.

In several embodiments, the polymer material has a flexural modulus of 100 MPa or 150 MPa or higher.

In several embodiments, the aforementioned mold engaging element includes a rod and at least one protrusion projecting from the rod, the top surface being formed as a curved surface.

In several embodiments, the top surface has a length and width in the direction in which the at least one protrusion projects from the rod, and a short width in a direction orthogonal to it. The short width is less than 2/5 (or more than 1/5) of the spacing between the male mold engaging elements or rows of male mold engaging elements in that direction. The short width may fall within the range of 0.3 to 0.9 mm (or within the range of 0.45 to 0.75 mm).

In several embodiments, the arrangement density of the aforementioned group of mold-fitting elements falls within the range of 20 to 100 elements/ ^cm² .

In several embodiments, at least one of the article components is a composite material with a napped fabric formed on the surface of the soft layer. The article can be a diving suit, sportswear, clothing, a bag, or a similar garment. [Creative Effect]

According to one aspect of this creation, it is possible to suppress the fuzzing of the fuzzy surface of the material used to make an item.

The following description, with reference to the diagrams, explains the non-limiting embodiments and features of this invention. When the item is clothing worn on the body, the inner side faces the body, and the outer side faces away from the body. When the item is not worn on the body, the inner and outer sides can be redefined according to the item's main characteristics. For example, when the item is a bag, its storage space is a primary characteristic; therefore, the inner side faces the space towards the storage space, and the outer side faces away from the storage space.

Figure 1 shows an article 1 as a non-limiting example, specifically the collar of a diving suit, including male and female mold parts 3 and 4, and at least one article material 2. Article 1 is a diving suit, and its article material 2 is the fabric part of the diving suit, but is not necessarily limited to this. Article material 2 may be a composite material with a napped woven or knitted structure (e.g., pile fabric) formed on the surface of a soft layer.

To elaborate further, a diving suit is made by sewing together multiple sheets of fabric of a specific thickness (3 mm, 5 mm, etc.) that provide both waterproofing and insulation. The fabric may have a soft layer such as a porous rubber sponge layer, and an epidermal layer formed (e.g., bonded or embedded) on one or both sides. The epidermal layer may contain woven or knitted structures for good contact with human skin and is sometimes referred to as a jersey layer. Woven or knitted structures are typically napped fabrics, but other fabrics are also possible. Of course, diving suit fabric is sometimes used in other items besides diving suits.

The male and female mold parts 3 and 4 are so-called face fasteners, fixed to different positions on the item 1 in a manner that allows them to contact each other. Specifically, they are located on both sides of the zipper extending from the collar to the waist of the diving suit. As described below, a napped area 5 is formed on the fabric around the female mold part 4, and the male mold part 3 can at least partially abut against this napped area 5. Furthermore, the napped area 5 does not need to be formed on the outside of the fabric part; it can also be formed on the inside of the fabric part. Since the fabric part is soft, it is foreseeable that the male mold part 3 will abut against the fabric part on the back side of the female mold part 4 (i.e., the inside of the fabric part).

The male mold portion 3 can be manufactured by general injection molding using an upper and lower mold assembly, or it can be manufactured using a mold wheel with forming cavities on its outer peripheral surface and an extruder. The female mold portion 4 can be manufactured from multiple threads using an automatic loom (e.g., knitted). Of course, there is no limitation on the number of male and female mold portions 3 and 4 included in article 1.

Looking at Figures 1 and 2 from the front, the male mold part 3 (e.g., by sewing, joining, etc.) is fixed to the inner surface of the fabric part 2a on the left side of the zipper, and the female mold part 4 (e.g., by sewing, joining, etc.) is fixed to the outer surface of the fabric part 2b on its right side. When putting on or taking off the wetsuit, the user cannot clearly see behind themselves. Therefore, as shown in Figure 2, the male mold part 3 is sometimes shifted to the right side of the female mold part 4 and pressed against the napped area 5 of the fabric part 2b. To release this state, the user pulls the fabric part 2a away from the fabric part 2b and presses it back against the fabric part 2b. This process can be repeated once to achieve the state shown in Figure 1 from Figure 2; otherwise, it requires further repetition. As a result, the male mold part 3 will repeatedly press (or apply pressure) against the napping area 5. Repeatedly performing this operation over a long period of time will cause the napping area 5 to nap.

The mold part 3 will be explained below. For ease of explanation, the mold part 3 is defined with a height direction D1, a front-to-back direction D2, and a horizontal direction D3. As will be explained below, the height direction D1 is consistent with the direction in which the mold engaging element 32 rises from the first base layer 31. The front-to-back direction D2 is a direction orthogonal to the height direction D1 and is consistent with the direction in which the protrusion 32b protrudes from the rod 32a (therefore, it may be the opposite direction between rows of the mold engaging element 32). The horizontal direction D3 is a direction orthogonal to both the height direction D1 and the front-to-back direction D2.

The male mold portion 3 has a first base layer 31 and a group of male mold engaging elements G32, which are arranged in a two-dimensional manner on the surface of the first base layer 31. The first base layer 31 and all the male mold engaging elements 32 are integrally formed from the same polymer material and are integrally continuous. The first base layer 31 is typically formed with a fixed thickness, but it can also be locally thinned. The first base layer 31 is fixed to the inner surface of the fabric portion 2a by sewing, bonding, welding, etc., and each of the male mold engaging elements 32 of the group of male mold engaging elements G32 protrudes from the fabric portion 2a (e.g., towards the inward side).

A group of male mold engaging elements G32 are arranged in a two-dimensional pattern, specifically in M rows × N columns, where M and N represent natural numbers greater than 2 (see Figure 3). Typically, the group of male mold engaging elements G32 are arranged in a two-dimensional pattern with a density ranging from 20 to 100 elements/ ^cm² . When the density is less than 20 elements/ ^cm² , it may be difficult to obtain sufficient peel strength and shear strength of the article 1 achieved by engaging with the female mold part 4. When the density exceeds 100 elements/ ^cm² , there is a risk of fraying in the fraying area 5.

Furthermore, the peel strength is defined as the force required to pull one of the engaged male mold portion 3 and female mold portion 4 away from the other in a plane perpendicular direction (e.g., to peel one end of the male mold portion 3 away from the female mold portion 4). The shear strength is defined as the force required to cause one of the engaged male mold portion 3 and female mold portion 4 to shift in position from the other in a plane direction.

Figure 3 illustrates a total of 9 male mold engaging elements 32 arranged in 3 rows × 3 columns, but the number is only illustrative. Figure 3 shows the _column direction D and the _row direction D, which can be referenced as needed. The male mold engaging elements 32 are arranged in _{the row} direction D, forming a receiving space for the coil 43 of the female mold portion 4 between adjacent male mold engaging elements 32. The male mold engaging elements 32 are arranged in the _column direction D, forming a space that allows the coil 43 to approach the male mold engaging elements 32.

Each mold engagement element 32 is a hook-shaped element whose engagement direction is defined in one direction in the circumferential direction of the element. Each mold engagement element 32 includes: a rod 32a, which stands on the surface of the first base layer 31; and at least one (typically a single) protrusion 32b, which protrudes from the rod 32a (e.g., the top of the rod 32a) along the surface at a height away from the surface of the first base layer 31. By protruding from the rod 32a by the protrusion 32b, a space SP1 is formed between the protrusion 32b and the surface of the first base layer 31, so that the coil 43 can engage with the protrusion 32b.

Referring to Figures 4 to 6, the mold engagement element 32 has a top surface 35, a rearward (front-rear) back surface 36, a front surface 37 (front-rear) front surface 38, and a concave surface 39. The front surface 37 rises substantially vertically from the surface of the first base layer 31. The back surface 36 includes an inclined surface that approaches obliquely forward (towards the front surface 37) as it rises from the surface of the first base layer 31. Therefore, the rod 32a has a gradually decreasing front-rear length as it leaves the first base layer 31. This helps to improve the flexibility of the mold engagement element 32.

The top surface 35 has two curved surfaces extending forward and backward from the highest position furthest from the first base layer 31, gradually approaching the first base layer 31. These two curved surfaces combine to form an arched curved surface. The top surface 35 can also be a flat surface, such as a flat surface parallel to the plane on which the first base layer 31 is disposed, but from the viewpoint of soft contact with the napped area 5, a curved surface is preferred. When viewing the engaging surface (a group of engaging elements G32) of the mold part 3 from the height direction, it can be observed that in each engaging element 32, its top surface 35 and its back surface 36 are adjacent in the front-back direction.

The boundary between the top surface 35 and the front surface 38 is located within plane L5. The boundary between the top surface 35 and the back surface 36 is located within plane L4. Both planes L4 and L5 are orthogonal to the plane containing the first base layer 31. The settings for each male mold engaging element 32 can be referred to the following description. In front view 5, plane L5 is located away from the leftmost male mold engaging element 32. When the plane (not shown) orthogonal to the plane containing the first base layer 31 is moved to the right toward the male mold engaging element 32, this plane is at the position where it first contacts the protrusion 32b of the male mold engaging element 32. Next, plane L6 is set to be parallel to the plane containing the first base layer 31 and includes the contact point P6 between plane L5 and the male mold engaging element 32. Plane L4 is positioned at the intersection point P7, which includes plane L6 on the side opposite to the contact point P6, where it intersects with the male mold engaging element 32.

Furthermore, the front end face 38 is a curved surface extending obliquely upwards towards the surface of the first base layer 31. The concave surface 39 is formed to a depth suitable for engaging with the engaging element (coil) of the female mold. The concave surface 39 is located on the opposite side of the top surface 35, which helps to soften the protrusion 32b.

The male mold engaging element 32 has sides 96 and 97 (see Figure 4) that define its width in the transverse direction D3. Typically, sides 96 and 97 are located in planes orthogonal to the transverse direction D3, and the male mold engaging element 32 has a fixed width, facilitating easy disengagement of the male mold engaging element from the forming cavity of the mold wheel. The male mold engaging element 32 may have auxiliary protrusions 33 on both sides of the rod 32a in the transverse direction D3, but the auxiliary protrusions 33 may be omitted. By providing the auxiliary protrusions 33, the mechanical strength of the male mold engaging element 32 can be improved, and the connection with the first base layer 31 can also be strengthened. The auxiliary protrusion 33 is formed to be lower in height than the rod 32a, thus ensuring sufficient flexibility of the male mold engaging element 32. Furthermore, in Figure 4, planes L1, L2, and L3 are provided at the center of the width of the male mold engaging element 32.

The male mold engaging element 32 can also be mushroom-shaped, with the engaging direction not limited in the circumferential direction of the element. A mushroom-shaped male mold engaging element may have, for example, a rod and a head. The rod has a circular, elliptical, or polygonal cross-sectional shape. The head is connected to the top of the rod and has a circular or elliptical top surface. The top surface of the head can be a flat surface or a curved surface.

Referring to Figures 7 to 10, the mold portion 4 and the napped area 5 will be further explained. The mold portion 4 is fixed to the fabric portion 2b by sewing, bonding, welding, etc. The mold portion 4 has a second base layer 41 and a group of coils G43 as one of a group of mold engaging elements. The group of coils G43 is formed by inverting each coil 43 on the surface of the second base layer 41. The group of coils G43 may be randomly formed (see Figure 7) or regularly formed (see Figure 8), or may be a combination or mixture of both. When the group of coils G43 is regularly formed, similar to a group of male mold engaging elements G32, the coils 43 may be arranged in a two-dimensional pattern with a density ranging from 20 to 100 coils/ ^cm² . Furthermore, the coil 43 may have the same height as the male mold engaging element 32. This ensures that the male mold engaging element 32 is smoothly hooked onto the coil 43. "Same" means a difference within ±5% of a specific value.

Figure 8 shows the master mold portion 4, which has regular loops 43. Each loop 43 is formed by bundling together a plurality of threads (filaments). Pairs of loops 43 in a V-shape are continuously formed along the weft direction, and the pattern is also replicated in the warp direction. Other knitting structures can also be used.

Figure 9 shows the woven or knitted structure exposed in the pileable area 5, specifically the pile group G6 formed by the two-dimensional arrangement of piles 6. The piles 6 are composed of multiple strands of yarn loops. The unit structure of the woven or knitted structure, specifically the piles 6, is tilted, which is different from the loops 43. Therefore, in this state, the male engagement element 32 will hardly hook onto the piles 6. However, if the male engagement element 32 is repeatedly pressed against the piles 6, the piles 6 are knocked and released, and the piles 6 or their constituent yarns easily stand up from the tilted state to an inverted state, becoming a state in which the male engagement element 32 can hook. As a result, as shown on the right side of Figure 10, the male mold engaging element 32 hooks onto the pile 6 or its constituent lines 59, and the pilling becomes obvious, which may lead to deterioration of the appearance of the fabric. Furthermore, although the pile 6 is located further away from the female mold part 4 when viewed from the male mold part 3, it does not solve the problem.

In this embodiment, a group of male mold engaging elements G32 includes two or more male mold engaging elements 32, each having abutment against the top surface 35 of the napping area 5. Furthermore, each of the group of male mold engaging elements G32 or the two or more male mold engaging elements 32 comprises the same polymer material having a flexural modulus of 800 MPa or less, 500 MPa or less, or 450 MPa or less. This suppresses the hooking of the male mold engaging elements 32 onto the unit fabric of the woven or knitted fabric as described above. Frankly, the male mold engaging elements 32 are sufficiently softened compared to ordinary male mold engaging elements (e.g., Comparative Example 2 below). This prevents the woven or knitted fabric unit structure from being easily knocked open due to the contact of the male mold engagement element 32, especially its top surface 35, thus avoiding the deterioration of the surface condition of the fabric portion 2b. Preferably, the polymer material has a flexural modulus of 100 MPa or 150 MPa or higher, thereby ensuring sufficient engagement with the coil 43 of the female mold engagement element. Furthermore, the flexural modulus is measured based on JIS K 7171. Polyester elastomers can be used as examples of polymer materials. In addition, polypropylene, polyethylene, polypropylene-polyethylene block copolymers, vinyl chloride, polyacetal, polyamide, elastomers, etc., can also be used as additions or alternatives.

Based on the dimensions of each plane of the male mold portion 3 and the female mold portion 4, or their relative positional relationship, it is not necessarily the case that all the male mold engaging elements 32 of a group of male mold engaging elements G32 abut against the roughened area 5 on their top surface 35. Therefore, the arrangement of a partial assembly of male mold engaging elements 32 of a group of male mold engaging elements G32 abutting against the roughened area 5 is also a hypothetical scenario. Nevertheless, from the perspective of design or manufacturing efficiency, it is typical that each male mold engaging element 32 of a group of male mold engaging elements G32 is formed with the same shape and the same size.

The maximum number of woven or knitted piles 6 that each top surface 35 can abut (in the pile-forming area 5) can be 9 or less, 7 or less, or 5 or less. In this case, the load on each pile 6 can easily reach a relatively significant level, the piles 6 are easily hooked, and the mold engagement element 32 is easily hooked. Therefore, it is particularly advantageous to use the mold part 3 of this invention. Furthermore, the pile 6 is a non-limiting example of a unit structure of woven or knitted fabric (the same applies below).

The minimum number of piles 6 that each top surface 35 can abut can be more than 2 or more than 3. The load in each pile 6 is distributed, thereby suppressing the hooking of the pile 6.

Based on the above two conditions, the number of velvets 6 that each top surface 35 can abut falls within the range of 2 to 9, specifically 2 to 7 or 2 to 5.

The top surface 35 may have a length and width W2 in the front-to-back direction D2 and a short width W1 in the lateral direction D3. The length and width W2 are defined between the two planes L4 and L5 mentioned above. The short width W1 is defined between the two parallel planes containing the side surfaces 96 and 97 (see Figure 4). The short width W1 is less than 2/5 of the spacing P1 between the common mold engagement elements 32 or the rows of common mold engagement elements in that direction (see Figure 4), and optionally more than 1/5 of the spacing P1. In this way, in relation to general woven or knitted structures, it is easy to facilitate controlling the number of piles that each top surface 35 can abut within a reasonable range. This design can suppress the influence on the arrangement density of the male mold engagement element 32 and various properties (peel strength, shear strength) of the face fastener, and also allows for easy adjustment of the area of the top surface 35. Furthermore, as in Embodiment 4 below, it can also promote the improvement of various properties (peel strength, shear strength) of the face fastener. The peel strength is preferably 2.0 N/cm or higher, but can also be a higher value. The shear strength is preferably 5.0 N/cm² ^or higher, but can also be a higher value.

Typically, the spacing P1 falls within the range of 0.3 mm to 4.0 mm, or 1.5 mm to 2.5 mm. Alternatively, the width falls within the range of 0.3 to 0.9 mm, or 0.45 to 0.75 mm. The length falls within the range of 0.5 to 1.5 mm, or 0.7 to 1.2 mm.

The aspect ratio (W1/W2) can be 0.2 or higher, or 0.4 or higher. Intentionally increasing the width will also increase the aspect ratio. However, if the aspect ratio is too large, it will be difficult to smoothly engage with the coil 43 of the female mold engagement element (for general opening sizes). Therefore, the aspect ratio should preferably be 1.8 or lower, or 0.7 or lower.

It should be clarified that in rows of adjacent male-shaped engaging elements 32 in the horizontal (column) direction, the protrusions 32b protrude in opposite directions from the rod 32a, but this is not necessarily the case. It is not limited to a single row; two rows can also be used as a unit to reverse the protrusion directions. The items are not limited to diving suits; they can also be sportswear, clothing, or bags. [Example]

The male mold portions of Comparative Examples 1 and 2 and Examples 1-3 were pressed against the napped areas of the same pile fabric 1000 times under the same load, and the degree of napping in the napped areas was observed. Except for Comparative Example 1, the male mold engaging elements were all hook-shaped as shown in the figure, arranged as illustrated. The pile density of the pile fabric was approximately 5000 piles/ ^cm² . Comparative Example 1: Instead of hook-shaped elements, a male mold portion made by cutting monofilament loops was used as the male mold engaging element. Polyamide with a bending modulus of 2800 MPa was used as the polymer material for the male mold portion. The arrangement density of the male mold engaging elements was 60 pieces/ ^cm² . Comparative Example 2: A male mold portion manufactured using polypropylene with a flexural modulus of 1800 MPa as the polymer material. The density of the male mold engagement elements is 39.2 elements/ ^cm² . The width and length of the top surface are 0.3 mm. The length and length of the top surface are 1.05 mm. Example 1: A male mold portion manufactured using polyester elastomer with a flexural modulus of 490 MPa as the polymer material. The density of the male mold engagement elements is 39.2 elements/ ^cm² . The width and length of the top surface are 0.3 mm. The length and length of the top surface are 1.05 mm. Example 2: A male mold portion manufactured using polyester elastomer with a flexural modulus of 290 MPa as the polymer material. The density of the male mold engagement elements is 39.2 pieces/ ^cm² . The width and shortest dimension of the top surface is 0.3 mm. The length and width of the top surface are 1.05 mm. Example 3: A male mold portion is manufactured using a polyester elastomer with a flexural modulus of 162 MPa as the polymer material. The density of the male mold engagement elements is 39.2 pieces/ ^cm² . The width and shortest dimension of the top surface is 0.3 mm. The length and width of the top surface are 1.05 mm.

As shown in Figure 11, compared with Comparative Examples 1 and 2, fuzzing in the fuzzing area was suppressed in Examples 1-3. A particularly favorable improvement was observed near the flexural modulus of 490 MPa in Example 1. Based on this result, it can be inferred that the ideal flexural modulus is below 500 MPa or less, and more preferably below 450 MPa or less. Comparing with Example 2, it can be inferred that the flexural modulus is further preferably below 300 MPa or less. Furthermore, a comparison between Comparative Example 2 and Example 1 suggests that even if the flexural modulus falls within the range of 500 MPa to 800 MPa, a certain degree of effectiveness can be achieved.

In Embodiment 4, the width-to-length ratio of the top surface of the male mold engaging element is doubled compared to Embodiment 2. In Embodiment 5, the width-to-length ratio of the top surface of the male mold engaging element is doubled compared to Embodiment 3. The spacing P1 remains constant. As shown in Figure 12, fuzzing is further suppressed. As shown in Figure 13, peel strength and shear strength are also improved. Comparing Embodiments 4 and 5, it can be seen that the following two conditions are useful: the bending modulus is below 300 MPa, and the width-to-length ratio falls within the range of 0.3–0.9 mm or 0.45–0.75 mm. The characteristics of the width-to-length ratio can also be understood by using the aspect ratio (W1/W2).
