Description
Technical Field
One aspect of the present invention relates to adhesive backings (adhesive backings) and laminated composites.
Background
A pressure-sensitive adhesive interlining (i.e., a pressure-sensitive adhesive interlining in which a pressure-sensitive adhesive for bonding a fabric is adhered to a base fabric) is known, which is used for preventing a shape from collapsing when sewing a garment to improve shape retention and workability (for example, patent document 1). For thick and heavy clothing (heavy clothing), a lightweight and soft type pressure-sensitive adhesive interlining having a bulky texture is required. To cope with such a demand, for example, the following means are employed: a method for manufacturing a pressure-sensitive adhesive interlining by improving the structure of a fabric used as a base fabric by designing a knitting structure, relatively thickening the yarn count, or raising the surface; alternatively, a nonwoven fabric having a bulky feeling may be used instead of the fabric used as the base fabric, and a binder for bonding the fabric may be attached to the nonwoven fabric itself to produce the fusible interlining.

Problems to be solved by the invention
However, the former method described above cannot provide a sufficient volume feeling. In the latter conventional method, although a certain volume feeling can be obtained, the texture (hand) becomes hard by using an adhesive, and flexibility is impaired.
It is therefore an object of one aspect of the present invention to provide a bonded liner and laminated composite that has a voluminous feel, yet is lightweight (lightweight) and soft in texture.
Means for solving the problems
An adhesive liner according to one aspect of the present invention includes: a base fabric (ground fabric) having a first surface and a second surface opposite to the first surface and having an adhesive portion made of resin formed on the first surface, and a nonwoven fabric integrally laminated on the second surface of the base fabric; wherein the value of the thickness of the composite of the base fabric and the nonwoven fabric divided by the grammage (basis weight) of the composite is 15 to 100.
In the pressure-sensitive adhesive interlining having such a configuration, since the volume feeling is ensured by using the nonwoven fabric, a voluminous feeling can be obtained which is light in weight and in which the value obtained by dividing the thickness of the composite of the base fabric and the nonwoven fabric by the grammage of the composite is 15 to 100, as compared with a method of attempting to ensure the volume feeling by designing the knitted structure of the base fabric itself, relatively thickening the yarn number, raising the surface, or the like. Further, since the base fabric is provided with the fabric-bonding adhesive, the nonwoven fabric itself does not have the fabric-bonding adhesive attached thereto, and therefore, the soft texture can be maintained. As a result, a lightweight and soft adhesive interlining having a voluminous feel can be obtained.
In the adhesive interlining according to one aspect of the present invention, the ratio of the thickness of the composite to the thickness of the base fabric may be 10 or more and 150 or less. In the pressure-sensitive adhesive sheet having such a structure, the nonwoven fabric can have a voluminous feel, and therefore a softer texture can be obtained.
An adhesive liner according to one aspect of the present invention includes: a base fabric having a first surface and a second surface opposite to the first surface, and having a bonding portion made of resin formed on the first surface, and a nonwoven fabric integrally laminated on the second surface of the base fabric; the ratio of the thickness of the composite of the base fabric and the nonwoven fabric to the thickness of the base fabric may be 10 to 150.
In the pressure-sensitive adhesive interlining having such a configuration, since the bulk feeling is ensured by using the nonwoven fabric, it is possible to obtain a voluminous feeling which is light in weight and in which the ratio of the thickness of the composite to the thickness of the base fabric is 10 to 150, compared with a method in which the bulk feeling is ensured by attempting to adopt a method of designing a knitted structure for the base fabric itself, relatively thickening the yarn number, raising the surface, or the like. In addition, since the nonwoven fabric itself does not have a binder for bonding fabrics attached thereto, the soft texture can be maintained. As a result, a lightweight and soft adhesive interlining having a voluminous feel can be obtained.
In the adhesive interlining according to one aspect of the present invention, the nonwoven fabric may be arranged in a state of being entangled (entangled) with the second surface of the base fabric. In the pressure-sensitive adhesive interlining having such a configuration, when the base fabric and the nonwoven fabric are integrally laminated, the bulky feeling of the nonwoven fabric can be maintained as compared with the case of using a pressure-sensitive adhesive.
In the adhesive backing according to one aspect of the present invention, the value of the thickness of the composite divided by the grammage of the composite may be 20 or more and 90 or less. As a result, a pressure-sensitive adhesive sheet having a softer texture can be obtained.
In the adhesive backing according to one aspect of the present invention, the value of the thickness of the composite divided by the grammage of the composite may be 30 to 80. As a result, a pressure-sensitive adhesive sheet having a softer texture can be obtained.
In the adhesive interlining according to one aspect of the present invention, the ratio of the thickness of the composite to the thickness of the base fabric may be 10 or more and 70 or less. As a result, a pressure-sensitive adhesive sheet having a softer texture can be obtained.
In the adhesive interlining according to one aspect of the present invention, the ratio of the thickness of the composite to the thickness of the base fabric may be 15 to 60. As a result, a pressure-sensitive adhesive sheet having a softer texture can be obtained.
In one aspect of the present invention, a laminated composite material includes: a base fabric having a first surface and a second surface opposite to the first surface, and a nonwoven fabric integrally laminated on the second surface of the base fabric; wherein the value of the thickness of the composite of the base fabric and the nonwoven fabric divided by the grammage of the composite is 15 to 100.
In the laminated composite material according to one aspect of the present invention, the ratio of the thickness of the composite of the base fabric and the nonwoven fabric to the thickness of the base fabric may be 10 or more and 150 or less.
In one aspect of the present invention, a laminated composite material includes: a base fabric having a first surface and a second surface opposite to the first surface, and a nonwoven fabric integrally laminated on the second surface of the base fabric; wherein the ratio of the thickness of the composite of the base fabric and the nonwoven fabric to the thickness of the base fabric is 10 to 150.
In the laminated composite material having such a structure, for example, a material in which an adhesive resin is disposed is simply bonded to a surface of the laminated composite material opposite to the surface on which the nonwoven fabric is disposed, whereby a light-weight and soft adhesive base material having a voluminous feel can be obtained.

Here, the term "intermingled" refers to a state in which the fibers forming the base fabric 3 and the fibers forming the nonwoven fabric 11 are entangled with each other.
The base fabric 3 is a woven fabric, for example, a fabric woven by using warp and weft in the case of a woven fabric. The warp and weft of the base fabric 3 may be made of crimped yarn. Examples of crimped yarns include false twist textured yarns. The false twist textured yarn is a textured yarn processed by a false twisting machine. The false twist textured yarn is a mainstream of crimp textured yarn, and is also called false twist yarn.
The base fabric 3 may be any material and structure as long as it has strength necessary for lining. Examples of the material include natural fibers such as cotton, hemp, silk and wool, regenerated fibers such as rayon and cuprammonium, semisynthetic fibers such as acetate and triacetate, synthetic fibers such as nylon, polyester, acrylic, urethane, polypropylene, polyethylene and polyvinyl chloride, and filaments of nylon fibers, polyester fibers or acrylic fibers are preferable. Examples of the cloth weave include a fabric (plain weave, twill weave, satin weave, etc.), a knit, and the like made of the above-mentioned material. In the present embodiment, the grammage (basis weight) of the base fabric 3 is 7 (g/m)2)～150(g/m2) About 8 (g/m) is preferable2)～120(g/m2) More preferably 8 (g/m)2)～100(g/m2). The thickness T2 of the base fabric 3 is about 0.050(mm) to 1.00(mm), preferably 0.060(mm) to 1.00(mm), and more preferably 0.07(mm) to 1.00 (mm).
The lower resin portion 4 is formed of resin R1. Examples of the resin R1 include polyurethane, acrylic, polyamide, polyester, polyethylene, EVA-based resin, PVA-based resin, and the like. The lower resin portion 4 is formed in a circular shape in plan view. The lower resin portion 4 is provided for favorably adhering the adhesive resin portion 5 formed of the resin R2 to the base fabric 3.
The resin R1 is more preferably a thermally crosslinkable resin crosslinked by heat. Examples of the thermally crosslinkable resin include resins obtained by adding an epoxy crosslinking agent to acrylic or polyurethane, and particularly preferred is a resin to which N-methylolacrylamide is added from the viewpoint of washing durability in the spent stage. The resin R1 may further contain at least one of a polymerization initiator, a crosslinking agent, a pigment, a dye, a drying inhibitor, and another modifier, if necessary.
The lower resin portion 4 is provided in a dot shape by a method of transferring onto the first surface 3a of the base fabric 3 with a roll screen or the like, and is fixed by subsequent bonding with heat or the like. The dot diameter of the lower resin portion 4 is 0.1(mm) to 2.0 (mm). The number of dots of the lower resin portion 4 was 1.3 (one/cm)2) 500 (pieces/cm)2). The dot mass of the lower resin portion 4 was 1.0 (g/m)2)～20(g/m2)。
The adhesive resin portion 5 is formed of a resin R2. As the resin R2, a thermoplastic resin which is generally called a hot-melt resin, which can be plasticized by heating and exerts an adhesive ability after cooling can be used. The adhesive resin portion 5 is formed in a circular shape in plan view. As shown in fig. 2, the adhesive resin portion 5 is provided to attach the adhesive liner 1 to the cover cloth 2.
Examples of the resin R2 include polyamide, polyurethane, polyester, polypropylene, polyethylene, and modified ethylene-vinyl acetate copolymer, and the like. The resin R2 may further contain at least 1 of a polymerization initiator, a crosslinking agent, a pigment, a dye, a drying inhibitor, and other modifiers, as necessary.
As described later in detail, the adhesive resin portion 5 is formed by: that is, the lower resin portion 4 is disposed on the first surface 3a of the base fabric 3, and the powder (resin powder) of the resin R2 is spread and heated to adhere a part of the powder of the resin R2 to the surface 4a of the lower resin portion 4. The mass of the adhesive resin portion 5 was 1.0 (g/m)2)～20(g/m2)。
The nonwoven fabric 11 is integrally laminated on the second surface 3b of the base fabric 3. In the present embodiment, the nonwoven fabric 11 is arranged in a state of being entangled (entangled) with the second surface 3b of the base fabric 3. That is, the base fabric 3 and the nonwoven fabric 11 are overlapped with each other in a state where the fibers forming the base fabric 3 and the fibers forming the nonwoven fabric 11 are entangled with each other. The nonwoven fabric 11 means a fiber sheet, web or rod in which fibers are oriented unidirectionally or randomly and the fibers are bonded by interlacing, and/or melt bonding, and/or adhesion, and does not include paper, fabric, knit, tufting and felting (JIS L0222). The nonwoven fabric 11 may be made of natural fibers such as cotton, wool, hemp, pulp, silk, and mineral fibers, or chemical fibers such as rayon, nylon, polyester, polypropylene, acrylic, vinylon, and aramid fibers. In the present embodiment, the nonwoven fabric 11 is a nonwoven fabric 11 made of polyester, and its grammage (basis weight) is 40 (g/m)2)～400(g/m2) Left, right, excellentIs selected to be 40 (g/m)2)～300(g/m2) More preferably 50 (g/m)2)～300(g/m2). The thickness T2 is 2.0(mm) to 30(mm), preferably 3.0(mm) to 30(mm), and more preferably 3.0(mm) to 20 (mm).
The nonwoven fabric 11 may be long fibers or short fibers. The method for producing the nonwoven fabric 11 is not particularly limited, but from the viewpoint of easily having a bulky feeling, it is desirable to use a chemical carbide method, a thermal bonding method, a needle punching method, or a spunlace method, and from the viewpoint of having a bulky feeling and being soft, a needle punching method is particularly preferable.
In the present embodiment, the thickness T1 of the base fabric 3, the thickness T2 of the nonwoven fabric 11, the grammage of the base fabric 3, and the grammage of the nonwoven fabric 11 are selected so that the value of the thickness T0 of the composite (laminated composite) 20 of the base fabric 3 and the nonwoven fabric 11 divided by the grammage of the composite 20 is 15 to 100, and the ratio of the thickness T0 of the composite 20 to the thickness T1 of the base fabric 3 is 10 to 150. Note that, in the present specification, the thickness of the base fabric and the grammage of the base fabric are determined by "JIS L1086: 2013 bond liner and bond cloth test method ". In the present specification, the thickness of the nonwoven fabric, the grammage of the nonwoven fabric, the thickness of the composite, and the grammage of the composite are defined by "JIS L1913: 2010 general nonwoven test method ".
Next, a method for manufacturing the adhesive liner 1 having the above-described structure will be described. In the method for manufacturing the adhesive liner 1 according to the embodiment, first, the following are prepared: base fabric 3, resin R1 forming lower resin portion 4, and resin R2 forming adhesive resin portion 5 disposed on surface 4a of lower resin portion 4.
Next, lower resin portion 4 is formed by adhering fixing resin R1 to first surface 3a of base fabric 3, and then fixing resin R2 is adhered to surface 4a of lower resin portion 4. Specifically, the resin R1 of the lower resin portion 4 formed in a paste state is attached in a dot shape on the first surface 3a of the base fabric 3. The resin R1 is attached in a dot shape to the first surface 3a of the base fabric 3 using a cylindrical screen printer that rotates around a predetermined rotation axis. A plurality of through holes for passing the resin R1 are formed on the outer peripheral surface of the screen printer in accordance with the number of dots.
A squeegee for supplying the resin R1 is provided in the screen printer. The resin R1 supplied from the squeegee is extruded through the through hole of the screen printer and adheres to the first surface 3a of the base fabric 3. The resin R1 is transferred onto the base cloth 3 conveyed while being sandwiched between the screen printer and the rear roller.
Next, the powder of the resin R2 as a thermoplastic resin is scattered on the first surface 3a of the base fabric 3 to which the resin R1 is transferred. Thereby, the resin R2 was adhered to the resin R1. Specifically, the resin R2 is spread on the first surface 3a of the base cloth 3 to which the resin R1 is attached using a hopper (disperser) for spreading powder (pulverized material) of the resin R2, and the resin R2 is attached to the surface 4a of the resin R1. Then, the excess powder of the resin R2 scattered on the base fabric 3 may be shaken off or blown off. For example, the excess resin R2 on the base fabric 3 is blown off by a blower that ejects air. The blown resin R2 is sucked by the suction nozzle and recovered.
Subsequently, the nonwoven fabric 11 is integrally laminated on the second surface 3b of the base fabric 3. Specifically, as shown in fig. 3, the nonwoven fabric 11 is integrally laminated on the second surface 3b of the base fabric 3 by disposing the nonwoven fabric 11 on the second surface 3b of the base fabric 3 and interlacing (entangling) the base fabric 3 and the nonwoven fabric 11. The interlacing of the base fabric 3 and the nonwoven fabric 11 is performed by needle punching or the like. Specifically, by the reciprocating movement of the metal needles in the needle loom, the needles catch the fibers of the nonwoven fabric 11, and the fibers of the nonwoven fabric 11 are pushed into the base fabric 3, thereby interlacing. When the pressure is too low during entanglement, the strength between the base fabric and the nonwoven fabric becomes weak, and peeling may occur during use, whereas when the pressure is too high, the density of the nonwoven fabric becomes too high, and the texture becomes hard, so that it is necessary to have a moderate pressure.
By the above-described method, the adhesive sheet 1 in which the nonwoven fabric 11 is integrally laminated on the second surface 3b of the base fabric 3 is formed.
The operation and effect of the adhesive liner 1 of the above embodiment will be described. In the fusible interlining 1 of the above embodiment and the fusible interlining 1 manufactured by the manufacturing method of the above embodiment, since the nonwoven fabric 11 is used to secure the voluminous feeling, it is possible to obtain a voluminous feeling which is light in weight and in which the value of the thickness T of the composite 20 of the base fabric 3 and the nonwoven fabric 11 divided by the grammage of the composite 20 is 15 to 100, compared to a method of attempting to secure the voluminous feeling by designing the weave structure of the base fabric 3 itself, relatively thickening the yarn count, raising the surface, and the like. Further, since the nonwoven fabric 11 itself does not have a binder for bonding fabrics (in the present embodiment, the lower resin portion 4 and the bonding resin portion 5) attached thereto, a soft texture can be maintained. As a result, the pressure-sensitive adhesive sheet 1 having a voluminous feel, light weight, and soft texture can be produced. When the value obtained by dividing the thickness T of the composite 20 of the base fabric 3 and the nonwoven fabric 11 by the grammage of the composite 20 is preferably 20 to 90, more preferably 30 to 80, the flexible pressure-sensitive adhesive sheet 1 can be obtained while further exhibiting a bulky feeling.
Further, in the adhesive interlining 1 of the above embodiment, the ratio of the thickness T0 of the composite 20 to the thickness T1 of the base fabric 3 is 10 to 150. Therefore, the nonwoven fabric 11 can have a voluminous feel, and a softer texture can be obtained. When the ratio of the thickness T0 of the composite 20 to the thickness T1 of the base fabric 3 is preferably 10 to 70, more preferably 15 to 60, the pressure-sensitive adhesive sheet 1 having a more flexible texture can be obtained while further exhibiting a voluminous feel.
In the above embodiment, the base fabric 3 and the nonwoven fabric 11 are physically entangled by a needle punching method. This can maintain the nonwoven fabric 11 having a low density and a high thickness. In the method of water-entangling (water-entangling) the base fabric 3 and the nonwoven fabric 11, since a high-pressure water stream is jetted to substantially the entire surface of the nonwoven fabric 11, the nonwoven fabric 11 is compressed and the bulk feeling cannot be maintained.
Conventionally, when a pressure-sensitive adhesive is applied in a spot form to a nonwoven fabric having a thickness itself (transfer printing), in the single-point method (a method in which a pressure-sensitive adhesive for bonding a fabric is directly applied to a nonwoven fabric), the nonwoven fabric is compressed by a pressure during processing, and the nonwoven fabric becomes hard and is difficult to be transferred in a spot form. In the case of the double-point method (a method in which a lower resin is attached to a nonwoven fabric and a fabric-bonding adhesive is attached to the lower resin), the lower resin penetrates into the interior of the nonwoven fabric too much, and the texture becomes hard, and the points are connected together, which causes a problem that it is difficult to obtain a bonding strength. In this respect, in the above-described embodiment, since the base fabric 3 is provided with the fabric-bonding adhesive (i.e., the lower resin portion 4 and the bonding resin portion 5), the dot arrangement of the lower resin portion 4 and the bonding resin portion 5, which has not been achieved in the case where the fabric-bonding adhesive is provided on the cotton-like nonwoven fabric 11 itself in the related art, can be achieved cleanly and stably. Thereby providing a soft texture.
Next, the pressure-sensitive adhesive sheet 1 of the present embodiment is described based on examples 1 to 8 and comparative examples 1 to 7 with reference to fig. 4 to 6, in which the pressure-sensitive adhesive sheet has a bulky texture and is lightweight and soft. Note that the meanings of the evaluation symbols shown in fig. 6 are as follows.
A: has extremely soft texture
B: has soft texture
C: a soft texture cannot be obtained

< comparative example 1>
In comparative example 1, the same base fabric 3 and nonwoven fabric 11 as those used in example 3 were used, but the base fabric 3 and nonwoven fabric 11 were integrally laminated by a water interlacing method, not by needle punching. In this case, the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained. In the drying step, fusion bonding occurs in the adhesive resin portion 5 of the adhesive liner 1.
< comparative example 2>
In comparative example 2, the same base fabric 3 and nonwoven fabric 11 as those used in example 2 were used, but the base fabric 3 and nonwoven fabric 11 were integrally laminated by a water interlacing method, not by needle punching. In this case, the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained. In the drying step, fusion bonding occurs in the adhesive resin portion 5 of the adhesive liner 1.
< comparative example 3>
In comparative example 3, the same base fabric 3 and nonwoven fabric 11 as those used in example 2 were used, and the base fabric 3 and nonwoven fabric 11 were integrally laminated by a thermal bonding method, not by integrally laminating the base fabric 3 and nonwoven fabric 11 with each other through entanglement. At this time, fusion bonding occurs in the adhesive resin portion 5 of the adhesive liner 1 due to the heat of thermal bonding at the time of lamination. Further, the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained.
< comparative example 4>
In comparative example 4, the same base fabric 3 and nonwoven fabric 11 as those used in example 2 were used, and the base fabric 3 and nonwoven fabric 11 were integrally laminated with chemical carbide, not by integrally laminating the base fabric 3 and nonwoven fabric 11 with each other through interdigitation. At this time, the nonwoven fabric 11 was in a state of being almost bonded to the surface by the chemical carbide, and the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained.
< comparative example 5>
In comparative example 5, the base fabric 3 used in example 2 was prepared, and the woven fabric had a yarn number of 3.0(dtex), a length of 51(mm), and a grammage of 270 (g/m)2) Per square inch (25.4X 25.4mm)2) 11385 (roots) of polyester. The base fabric 3 and the nonwoven fabric 11 are interlaced with each other by needle punching. In this case, the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained. It is considered that the thickness of the nonwoven fabric 11 is too large to be used for clothing, and therefore, a soft texture cannot be obtained.
< comparative example 6>
In comparative example 6, the base fabric 3 used in example 2 was prepared, andyarn count of 3.0(dtex), length of 51(mm), per square inch (25.4X 25.4mm)2) 4217 (pieces) of polyester, and a gram weight of 100 (g/m)2) The nonwoven fabric 11 of (1). The base fabric 3 and the nonwoven fabric 11 are interlaced with each other by needle punching. In this case, the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained. In this case, it is considered that since the base fabric 3 has a large number of fibers per unit volume and a high density, it is in a state of a pattern other than cotton, and the shearing force is hard, so that a soft texture cannot be obtained.
< comparative example 7>
In comparative example 7, the base fabric 3 used in example 2 was prepared, and the woven fabric had a yarn number of 6.6(dtex), a length of 64(mm), and a grammage of 30 (g/m)2) Per square inch (25.4X 25.4mm)2) 481 polyester nonwoven fabric 11. The base fabric 3 and the nonwoven fabric 11 are interlaced with each other by needle punching. In this case, the first evaluation value and the second evaluation value did not reach the target values, and soft texture (evaluation C) was not obtained. In this case, it is considered that since the thickness of the nonwoven fabric 11 is too small, a desired volume feeling is not obtained and a soft texture is not obtained.
While the embodiment has been described above, one aspect of the present invention is not limited to the above embodiment. Various modifications can be made without departing from the scope of the present invention.
In the case where a nonwoven fabric having a weak bonding force between fibers constituting the nonwoven fabric, such as a nonwoven fabric made of a chemical carbide, is used as the nonwoven fabric 11, a coating layer made of a resin (excluding a hot melt) may be formed on the first surface of the nonwoven fabric 11 on the interface side with the base fabric 3, as long as the texture of the nonwoven fabric 11 is not significantly damaged. The coating is formed, for example, by performing an acrylic emulsion treatment. When the first surface of the nonwoven fabric 11 is provided with the coating layer, when the nonwoven fabric 11 and the base fabric 3 are entangled, defects such as cotton displacement can be suppressed in the nonwoven fabric having a weak bonding force between fibers constituting the nonwoven fabric.
In the above embodiment or modification, the nonwoven fabric 11 is disposed in a state of being interlaced with the second surface 3b of the base fabric 3, but the nonwoven fabric 11 may be integrally laminated on the second surface 3b of the base fabric 3 by chemical carbide as long as the texture of the nonwoven fabric 11 is not significantly impaired.
In addition to the structure of the base fabric 3 of the above embodiment or the modified example, a resin portion for filling may be formed on the second surface 3b of the base fabric 3.
In the above embodiment or modification, the adhesive interlining 1 is exemplified, but a composite (laminated composite) having no adhesive resin portion (adhesive portion) 5 provided on the base fabric 3 may be used. In the laminated composite material having this configuration, a lightweight and flexible adhesive base material having a voluminous feel can be produced by a simple process of bonding only a material in which an adhesive resin is disposed to a surface on the opposite side to the side in which the nonwoven fabric 11 is disposed.
