Description

Technical Field

[0001] The present invention relates to clothing.

Background Art

[0002] Conventionally, in clothing having a tightening part using adhesion, as techniques for forming the tightening part, methods such as adhering band-shaped rubber, methods of adhering two pieces of fabric in a dot shape, tape, or film shape, and methods of using fabric that does not require end processing without joining anything have been variously studied.

[0003] For example, Patent Document 1 proposes clothing in which the stress difference at 50% elongation of the joint part and the part parallel thereto is reduced by dot-shaped adhesion or the like.

[0004] Also, Patent Document 2 proposes a clothing item in which a cut work is facilitated by adhering a stretchable warp-knitted strip to clothing using a thermoplastic resin adhesive film, that is, a hot melt tape or the like.

[0005] Further, Patent Document 3 proposes a related technique in which, for stretchable fabric, a resin with poor stretchability is used to follow the fabric by laminating it using a discontinuous adhesive such as a zigzag shape.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in the case of clothing in which the fastening part is adhered with a thermoplastic resin, i.e., a hot melt resin, it has been found that the adhered parts in the form of dots, tapes, or films are likely to peel off during use. When examining the cause, it has been found that there are particularly problems with washing durability, especially with high-temperature washing durability.

[0008] In addition, in the case of dot-shaped adhesion, the stress of the fastening part becomes weak, and in the case of tape or film-shaped adhesion, the stress is too strong, resulting in a problem of poor comfort. When zigzag adhesion is performed, the elongation characteristics of the fabric can be adjusted so as not to change as much as possible, but it is difficult to impart elasticity to the fastening part. When the stress is increased, it is difficult to wear the clothing, and when the stress is decreased, the fastening property deteriorates.

[0009] The present invention has been made in view of the above, and an object thereof is to provide clothing that is excellent in high-temperature washing durability and has good comfort.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as "embodiments") will be described with reference to the accompanying drawings. Note that the drawings are merely schematic and are not limited to the drawings.

[0015] (Embodiment 1) The clothing of the present invention is clothing having a tightening portion to be held on a human body part of a wearer, and the tightening portion has an overlapping portion including at least a body fabric and an overlapping fabric.

[0016] Figure 1 is a diagram showing the configuration of the clothing according to Embodiment 1. The clothing 1 shown in the figure is an example of men's underwear and has a tightening portion 2 for holding the waist. Further, there may be a tightening portion 3 for holding the feet.

[0017] In the present invention, the tightening portion refers to a portion having a strong tightening force. In the present invention, the tightening force means the elongation stress when worn or when the assumed elongation when worn is performed.

[0018] The body fabric 4 of the clothing 1 is made of a stretchable fabric. There is no particular limitation as long as the clothing defined in the present invention can be obtained. For example, as long as it is a knitted fabric provided as a general clothing material, it is not limited, but round-knitted or warp-knitted fabrics have stretchability particularly suitable for the implementation of the present invention and are preferable. Also, even if it is a woven fabric, a fabric having stretchability for clothing is suitable for the present invention. In addition, the fabric used for the materials of general underwear, undergarments, innerwear with cups, and outerwear such as T-shirts and cut-sleeves can also be applied and is not limited.

[0019] The overlapping fabric 5 of the clothing 1 is made of a stretchable fabric. There is no particular limitation as long as the clothing defined in the present invention can be obtained. For example, as long as it is a knitted fabric provided as a general clothing material, it is not limited, but round-knitted or warp-knitted fabrics have stretchability particularly suitable for the implementation of the present invention and are preferable. Also, even if it is a woven fabric, a fabric having stretchability for clothing is suitable for the present invention. In addition, the fabric used for the materials of general underwear, undergarments, innerwear with cups, and outerwear such as T-shirts and cut-sleeves can also be applied and is not limited.

[0020] In the present invention, the material of the yarn applied to the stretchable fabric used for the body fabric 4 and the overlay fabric 5 is not particularly limited. For example, polyester-based synthetic fibers such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate, polyamide-based synthetic fibers such as nylon, synthetic fibers such as polyacrylonitrile and polypropylene, regenerated fibers such as rayon, polynosic, and cupra, semi-synthetic fibers such as acetate and triacetate, natural fibers such as cotton, hemp, wool, and silk, polyurethane elastic fibers, polyether-ester elastic fibers, polyamide elastic fibers, polyolefin elastic fibers, or so-called rubber yarns in the form of filaments made of natural rubber, synthetic rubber, or semi-synthetic rubber, elastic fibers such as special fibers obtained by covering synthetic fibers with rubber, etc. can be used, and one or more of these can be used according to the required characteristics. Further, those containing additives such as titanium oxide in the above-mentioned fibers may be used, or fibers polymer-modified for imparting functionality may also be used. For example, it is also preferable to use the above-mentioned polyester-based synthetic fibers, polyamide-based synthetic fibers such as nylon, elastic fibers, etc. in combination with synthetic fibers such as the above-mentioned polyacrylonitrile and polypropylene, regenerated fibers, semi-synthetic fibers, natural fibers, etc. in that the properties of different fibers can be expressed in a composite manner.

[0021] Also, the cross-sectional shape of the single fiber unit is not defined, and various profiled cross-section yarns represented by round, triangular, eight-leaf, flat, and Y-shaped can also be used. Furthermore, core-sheath type or side-by-side type composite yarns made of polymers with different viscosities can also be used.

[0022] Also, false-twisted yarns obtained by subjecting these fibers to false-twisting processing using the raw yarns may be used.

[0023] Furthermore, the most suitable material may be appropriately selected according to the application.

[0024] In the present invention, the overlay fabric is fixed to the body fabric by an adhesive attached in a multi-row pattern of three or more rows parallel to the direction in which the tightening force acts.

[0025] FIG. 2 schematically shows a state in which an overlapping portion of the tightening portion of the clothing shown in FIG. 1 and an adhesive are provided. More specifically, it is a diagram schematically showing a state in which the tightening portion 2 and the adhesive 10 of the clothing 1 according to Embodiment 1 are provided, and a substantially belt-shaped overlapping fabric 5 having the same shape as the shape of the tightening portion 2 that holds the waist constituting the clothing is overlapped from above. It is shown excluding a part of the overlapping fabric 5 to show the state where the adhesive is provided. In FIG. 2, the adhesive 10 is provided in a multi-row of 5 rows, and each 1 row along the end of the overlapping fabric 5 (hereinafter referred to as the upper and lower 1 row) is an adhesive 10A provided linearly, and in the central portion, there are 3 rows provided with columns of adhesives 10B provided in a dot shape. The number of linear rows, the number of rows of adhesives provided in a dot shape, and the linear and dot-like arrangements are not particularly limited as long as they satisfy the range defined in the present invention, but it is preferably in a manner such as the configuration pattern of the adhesive 10 described later.

[0026] In the present invention, the width of the overlapping portion is preferably 10 to 100 mm, more preferably in the range of 30 mm to 40 mm, in order not to disperse or concentrate the pressure of the tightening portion. In FIG. 2, the width of the overlapping portion is configured to be 30 mm. Note that the width of the overlapping portion refers to the dimension in a direction perpendicular to the direction in which the tightening force is applied, for example, the dimension in the length direction in the tightening portion 2 in FIG. 1, in other words, the dimension in a direction perpendicular to the circumference of the waist.

[0027] In the present invention, the overlapping may be in a state where the body fabric constituting the clothing is folded in half, or may be constituted by overlapping other parts on the tightening part. When overlapping other parts, the same fabric as the body may be used, or other fabrics may be used. In the present invention, the overlapping part refers to the above-mentioned overlapped part, and the end part thereof means that when the body fabric is folded in half to form the overlapping part, one end forms a fold mountain, and the other end that is folded back corresponds to the end part of the overlapping part. Further, when overlapping the overlapping fabric which is another part, when this overlapping fabric is overlapped, it corresponds to two end parts along the direction in which the tightening force acts (the circumferential direction of the waist in the tightening part 2 in FIG. 1). In FIG. 2, although the upper end part of the body fabric 4 and the end part of the overlapping fabric are displaced, they may coincide. It may be provided at a position where the tightening force is to be applied.

[0028] In the present invention, among the rows of the adhesive attached to the overlapping fabric 5, the row of the adhesive closest to each end of the fabric parallel to the direction in which the tightening force acts is linearly attached within 2.0 mm from the fabric end, and among the rows of the adhesive attached to the overlapping fabric, the row of the adhesive at the central part is attached in a dot shape.

[0029] In the present invention, the number of linear rows is one or more in the vertical direction, and more preferably two or more in order to disperse the pressure. From the viewpoint of the balance of the tightening force, it is preferable that the number of upper and lower linear rows is the same, but it may be appropriately changed according to the required mode of the tightening force.

[0030] The width (dimension in a direction perpendicular to the direction in which the tightening force acts) of the linearly attached adhesive (hereinafter referred to as the linear adhesive) is preferably 0.5 to 10.0 mm, and preferably 0.7 to 2.0 mm in order to control the tightening force that is not too strong while maintaining the adhesive force. For example, in FIG. 2, the linear adhesive 10A in one row in the vertical direction is configured to have a width of 1.0 mm.

[0031] As shown in Fig. 2, the adhesive 10 is arranged in one or more upper and lower rows linearly and in a dot pattern in the central row along the end of the overlapping fabric 5 of the tightening part 2. When the distance d1 between the end of the overlapping fabric 5 and the uppermost and lowermost rows of the adhesive 10 becomes large, the end of the fabric is likely to become a free end and warp when overlapped. Therefore, the distance d1 from the end of the fabric to the row of the adhesive is within 2.0 mm, preferably within 0.5 to 1.0 mm.

[0032] As described above, the configuration pattern of the adhesive 10 in the tightening part 2 is linear in the uppermost and lowermost rows and dot-shaped in the central part with respect to the longitudinal direction of the tightening part 2 (the direction in which the tightening force acts). The linear shape means that the adhesive 10A is connected in a solid line shape, excluding broken lines and dotted lines. As the linear shape, as long as the range defined in the present invention is satisfied, it may be composed of a straight line shape, a wavy line shape, a zigzag shape, etc. However, in order to efficiently impart elasticity to the adhesive 10A, a straight line shape along the longitudinal direction of the tightening part 2 (the direction along the end of the fabric at the overlapping part, and for example, the circumferential direction of the waist part in Fig. 1) is preferable. Also, the number of rows in the upper and lower rows is not limited as long as each is one or more. For example, the upper 6 rows and the lower 5 rows out of a total of 12 rows are linear, and the 6th row from the bottom may be attached in a dot pattern.

[0033] In the present invention, the central part does not necessarily have to be exactly in the center between the upper and lower linear adhesives. It means the region sandwiched between the uppermost and lowermost rows of linear adhesives or the uppermost and lowermost rows and one or more rows of linear adhesives adjacent to them. If there are adhesives attached in a dot pattern within that region, it may be regarded that there are adhesives attached in a dot pattern in the central part. As long as the range defined in the present invention can be satisfied, there is no limit to the number of each row, and it may be appropriately determined according to the required tightening force.

[0034] Also, as the configuration pattern of the adhesive 10, it is preferable that the interval d3 between rows is equal. More specifically, it does not necessarily have to be exactly equal. As long as the difference between the smallest interval and the largest interval between the rows where the adhesive is attached in the tightening part 2 is within 10% of the largest interval, it is regarded as equal.

[0035] In the present invention, the row of adhesive agents (hereinafter referred to as dot-shaped adhesive agents) attached in a dot shape at the central part may be formed by irregularly attaching a plurality of dots into a strip-shaped row, or the dots may be regularly arranged in a single dotted line. From the viewpoint of production efficiency, it is preferable to regularly arrange them in a single dotted line.

[0036] The dot-shaped adhesive agent at the central part preferably has a diameter of 0.5 to 10.0 mm. Among them, from the viewpoint of fully utilizing the elongation of the fabric, it is preferably 2.0 mm or less in diameter, more preferably 1.0 mm or less. Here, the diameter means the equivalent circular diameter in the case where the dot shape is non-circular. For example, in FIG. 2, the dot-shaped adhesive agent 10B is configured to have a diameter of 1.0 mm.

[0037] In the case of a single row of dot-shaped adhesive agents, the interval d2 between the dots is preferably 0.1 to 50.0 mm, and is preferably uniform in the longitudinal direction, that is, in the direction parallel to the linear direction. More specifically, it is not necessary to be strictly uniform, and if the difference between the smallest interval and the largest interval between adjacent dots d2 is within 10% of the largest interval, it is regarded as uniform. The interval between the dots refers to the distance from the central part of one dot to the central part of the adjacent dot. For example, in FIG. 2, the interval between two adjacent dot-shaped adhesive agents 10B in the same row is configured to be 2.0 mm. Also, if the interval d2 is too wide compared to the diameter of the dot-shaped adhesive agent 10B, the uneven feeling when worn becomes more prominent, the wearing feeling is likely to deteriorate, and the appearance is likely to deteriorate. Therefore, in the case of the diameter R of the dot-shaped adhesive agent 10B, it is preferable that 1.5×R≦d2<4×R.

[0038] The dot-shaped adhesive agent 10B is circular in shape in Embodiment 1, but is not limited thereto as long as the range defined in the present invention is satisfied. As long as it is a shape in which the adhesive agents can be repeatedly attached in a separated state so that the interval between the adhesive agents can be changed, it may be a broken line shape, a geometric shape, or a combination thereof.

[0039] In the present invention, the hot peel strength when heating the overlapping part at 100°C is 5.0 N / 2.54 cm or more.

[0040] The resin constituting the adhesive 10 has been found that the problem of peeling during consumers' use, which was a conventional problem, is mainly caused by rubbing and peeling forces during heating due to repeated high-temperature treatments such as washing and tumble drying. Therefore, as a means of solution, the hot peel strength when heating the overlapping part at 100°C is 5.0 N / 2.54 cm or more. If it is less than 5.0 N / 2.54 cm, a problem of peeling occurs during high-temperature washing or tumble drying at about 90°C performed in Europe and the like. If it is 5.0 N / 2.54 cm or more, peeling can be suppressed even when performing a high-temperature treatment at about 90°C. To increase the peel strength, a method of increasing the hardness of the resin can be considered. However, since excessive increase in hardness affects the elongation rate, it is preferably 6.0 to 40.0 N / 2.54 cm.

[0041] The method for measuring the hot peel strength uses a tensile testing machine and a constant temperature bath, for example, the desktop precision universal testing machine AGS-5kNX of Shimadzu Corporation and the constant temperature bath TCE-N300A, and the test is carried out in accordance with the method described in "JIS L1086:2020 Test Methods for Adhesive Interlinings and Adhesive Fabrics" while heating at 100°C. The method of measuring while heating at 100°C is that after the temperature in the constant temperature bath is stabilized at 100°C, the test piece is set on the tensile testing machine in the constant temperature bath. After closing the constant temperature bath, after it is stabilized at 100°C again (about 2 minutes after setting the test piece), the measurement shall be carried out. In addition, in the present invention, since the portions to be evaluated are linear and dot-like adhesions, the conversion width of the peel strength is converted to the actual adhesion width. For example, when the width of the test piece is 2.54 cm, there are 2 rows of linear adhesions with a width of 0.1 cm and 8 rows of dot-like adhesions with a diameter of 0.1 cm, and the measured hot peel strength is 10 N, the hot peel strength of the measured test piece is 10 N / 2.54 cm. However, since the actual adhesion width is 1.0 cm, it is converted to 10 N / 1.0 cm = 25.4 N / 2.54 cm. As a method for measuring the actual adhesion width in the case where a plurality of dots are irregularly attached to form a strip-like row, the actual dimension width of the adhesive in the test piece width direction is randomly measured at 5 locations, the average is obtained, and conversion is performed based on this.

[0042] As the method for the above-mentioned high-temperature washing at about 90°C, the conditions of 9 N (liquid temperature 92°C) in "JIS L1930:2014 A-Type Test Method (Drum Type)" are used, and washing is carried out 5 times. After 5 times of washing, drying is performed under the conditions of high-temperature tumble drying described in "JIS L 1096:2020 Test Methods for Fabrics and Knitted Fabrics 8.39.6 Drying Method", and the presence or absence of peeling is confirmed.

[0043] In the present invention, the elongation rate in the direction parallel to the linear direction of the linear part where the adhesive is linearly attached is 50% or more, the elongation recovery rate is 85% or more, and the difference in the elongation recovery rate in the direction parallel to the linear direction between the linear part and the dot-like part where the adhesive is linearly attached is within 10%.

[0044] Since the elongation rate of the portion where the adhesive is linearly attached is 50% or more and the elongation recovery rate is 85% or more, the detachability and wearing comfort are excellent. Among them, the elongation rate of the portion where the adhesive is linearly attached is preferably 70% or more from the particularly excellent detachability. Considering the ease of wearing, the upper limit is preferably within 200%.

[0045] Also, the elongation recovery rate of the portion where the adhesive is linearly attached is 85% or more, preferably 90% or more. This enables excellent wearing comfort to be maintained without sagging even when worn repeatedly. The upper limit is 100%, but in reality it is 99% or less.

[0046] The method for measuring the elongation rate and elongation recovery rate of the portion where the adhesive is linearly attached is as follows: The elongation rate is measured according to the test method in accordance with Test Method B-1 for Elongation Elastic Modulus and Residual Strain Rate of Woven and Knitted Fabrics described in "JIS L1096:2020 Test Methods for Fabrics of Woven and Knitted Fabrics". After one elongation, a hysteresis curve is obtained by recovering at the same speed, and the elongation rate at a maximum stress of 14.7 N and the "elongation recovery rate = 1 - residual strain amount / elongation amount at a maximum stress of 14.7 N" at a minimum stress of 0 N are measured. The width of the test piece is not the specified width, but the test is carried out only on the width of the portion where the adhesive is linearly attached. When the number of columns in the upper and lower rows is different, the upper and lower rows are measured respectively, and their average values are taken as the elongation rate and elongation recovery rate. As for the method of collecting the test piece, in the portion where the adhesive is linearly attached, since the linear adhesive on the end side is attached at a position of the distance d1 from the end of the laminated fabric, for the end side, the end of the laminated fabric is used as the end of the test piece, and for the other end of the test piece, it is set to be the same as the distance d1 from the linear adhesive adjacent to the dot. When the dot-shaped laid portion is too close and the distance cannot be measured, the test piece is collected by cutting so that the middle between the adjacent dot-shaped rows becomes the end of the test piece.

[0047] In the tightening part 2, since the adhesive 10 is composed of a linearly attached part and a dot-like attached part, if the difference in the elongation recovery rate in the longitudinal direction is large, repeated attachment and detachment may lead to appearance defects such as waviness or deterioration of the wearing comfort in the tightening part 2. Therefore, the difference in the elongation recovery rate between the linearly attached part and the dot-like attached part of the adhesive 10 is within 10%, preferably within 5%. The preferable lower limit is 0%, but in reality, it is 2% or more.

[0048] The method for measuring the difference in the elongation recovery rate between the linearly attached part and the dot-like attached part of the adhesive 10 is to conduct a test in accordance with Test Method A for Elongation Elastic Modulus and Residual Strain Rate of Woven and Knitted Fabrics described in "JIS L1096:2020 Test Methods for Fabrics and Knitted Fabrics", and the number of repetitions is up to 3 times. Since the width of the test piece is different from the specified value, the test is conducted with the test piece widths of the linearly attached part and the dot-like attached part of the adhesive 10 adjusted to be the same. For example, when the linearly attached part is 10 mm, the dot-like attached part is also made into a 10-mm-wide test piece. Measure the elongation recovery rate B1 (%) of the linearly attached part and the elongation recovery rate B2 (%) of the dot-like attached part, and calculate the difference B0 (%) in the elongation recovery rate between the linearly attached part and the dot-like attached part using the calculation formula B2 - B1 = B0.

[0049] In the present invention, among the adhesives attached in the form of three or more rows of multiple rows, for the adhesive constituting the adhesive 10A which is the linear part of the adhesive, a resin having elasticity and heat resistance that can achieve the elongation rate and elongation recovery rate defined in the present invention and can achieve the above-mentioned hot peel strength is used. Since the adhesive has elasticity, stretchability can be imparted to the fabric after fixing. As the type of resin, synthetic resin is more preferable than natural resin, and among them, reactive resin is more preferable. Among these, it is preferable to use a reactive polyurethane resin (reactive PU) or a reactive silicone rubber having elasticity. Such reactive resins can be selected from commercially available products. For example, ND5011 manufactured by Xinfayuan Automation Technology Co., Ltd. can be used.

[0050] In addition, as the resin constituting the adhesive 10B, a resin having heat resistance that can achieve the above-mentioned hot peel strength is used. As the type of resin, synthetic resin is preferable to natural resin, and among them, reactive resin or a thermoplastic resin having a high softening point temperature of 110 °C or higher is more preferable, and reactive resin is even more preferable. For example, in addition to polyethylene, polypropylene, polytetrafluoroethylene, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyethersulfone, polyetheretherketone, polyimide, polyamideimide, silicone, etc., those made of polymer compounds, silicone rubber, butadiene rubber, isoprene rubber, vulcanized rubber, styrene-butadiene rubber, butyl rubber, chlorosulfonated polyethylene rubber, ethylene-propylene rubber, vinylidene fluoride copolymer, etc. may be mentioned, and the same adhesive as the adhesive 10A may be used. The reactive resin preferably used as the adhesive 10A is also a preferable adhesive as the adhesive 10B. Note that although the thermoplastic polyurethane resin (thermoplastic PU) used as a normal hot melt adhesive is inferior in heat resistance, it can be used for the adhesives 10A and 10B as long as it has heat resistance satisfying the hot peel strength of the present invention.

[0051] In the tightening part 2, in order to reduce the displacement during wearing, it is preferable that the dimension of the tightening part 2 is about 30% smaller than the body dimension, and it is also preferable to control so that the stress of the tightening part 2 at the time of 30% elongation equivalent to that during wearing becomes 3.5 to 6.0 N / 2.54 cm. By setting the elongation stress at 30% elongation to 6.0 N / 2.54 cm or less, it is possible to avoid giving discomfort due to a strong sense of compression during wearing, and by setting it to 3.5 N / 2.54 cm or more, it is difficult to cause a problem of displacement during wearing. Therefore, it is preferable to suppress the elongation stress within the above range.

[0052] The method for measuring the elongation stress was carried out according to the test method in accordance with Test Method A for Elongation Elastic Modulus and Residual Strain Rate for Woven and Knitted Fabrics described in "JIS L1096:2020 Test Methods for Fabrics of Woven and Knitted Goods". The elongation rate was measured, a hysteresis curve with only one elongation / recovery was obtained, and the elongation stress at the 30% elongation point during unloading at that time was measured. Since the width of the test piece was different from the regulation, after conducting the test according to the width of the overlapping part of the tightening part, the calculation of "measured stress at 30% elongation ÷ test piece width (cm) × 2.54 (cm)" was performed to calculate the stress at a width of 2.54 cm.

[0053] In the present invention, the areal density of at least one of the body fabric or the overlapping fabric of the overlapping part is preferably 80 to 140 g / m 2 2.

[0054] The method for measuring the areal density of the fabric shall be measured according to the method in accordance with "JIS L 1096:2020 Test Methods for Fabrics of Woven and Knitted Goods 8.3.2 Mass per Unit Area in Standard State".

[0055] Regarding the areal density of the body fabric or the overlapping fabric, in men's underwear, especially in summer, the feeling of stuffiness may be a concern. In order to eliminate the feeling of stuffiness, it is preferable to use a fabric with a lower areal density. It is more preferable to use a fabric having an areal density of 80 to 140 g / m 2 in at least one of them, and it is particularly preferable to use a fabric having an areal density of 90 to 130 g / m 2 2. It is an even more preferable aspect that both the body fabric and the overlapping fabric have the above areal density.

[0056] When using a fabric with a lower areal density for the body fabric or the overlapping fabric, in order to increase the tightening force in the tightening part, the areal density of the other fabric is preferably equal to or higher, and it may be a fabric having an areal density of 80 to 180 g / m 2 2.

[0057] In order to further increase the hot peel strength, it is preferable to make the penetration of the adhesive as follows. That is, in the cross section of the overlapping part, the thickness of the resin penetration layer A on the a-side of the fabric, which is the fabric with a relatively low basis weight or the body fabric with the same basis weight among the body fabric and the overlapping fabric (A t ), the thickness of the resin penetration layer B on the b-side of the fabric, which is the fabric with a relatively high basis weight or the overlapping fabric with the same basis weight (B t ), and the thickness of the resin layer C by the adhesive (C t ), when the total is 100%, it is preferable that A t is 20% - 30%, B t is 20% - 40%, and C t is 30% - 60%. Among them, it is more preferable that A t is 25% - 30%, B t is 30% - 35%, and C t is 35% - 45%.

[0058] Also, the ratio of the thickness of the resin penetration layer A (A t ) to the thickness of the a-side of the fabric (a t ), (A t / a t ) is preferably 0.2 - 0.6, and more preferably the ratio of the thickness of the resin penetration layer A to the thickness of the a-side of the fabric (A t / a t ) is 0.4 - 0.6.

[0059] As a method for measuring the above thickness, cut the cross section of the overlapping part, use a digital microscope (for example, KEYENCE digital microscope VHX-F series) to take images at 100 magnifications, measure the thickness (length) of each layer, and perform calculations. As the method for measuring the thickness, the average value of the thickness of the part where the resin has penetrated into the fabric (the average of the most penetrated part and the least penetrated part) is used as the resin penetration layer thickness, and for the resin layer, the average value of the thickest part and the thinnest part in the layer is used as the resin layer thickness. When sampling the sample, exclude the part joined to other members.

[0060] Figure 3 is a cross-sectional view of the overlapping portion of the tightening part of the clothing shown in Figure 1. A relatively low-grammage fabric or the body fabric a of the same grammage and a relatively high-grammage fabric or the overlapping fabric b of the same grammage are adhered with an adhesive. At the interface, a resin layer C by the adhesive can be observed between the resin penetration layer A on the fabric a side and the resin penetration layer B on the fabric b side.

[0061] As a processing method for adhesion, either a method of using a cylinder-type press machine for heating and pressurization or a method of using a mangle roller for heating and pressurization may be used, and it is not limited. As a method for controlling pressure, those by air control, those by clearance control, and further a method of controlling the pressure applied to an object by changing the material of the mangle, etc. may be mentioned, and it is not limited.

[0062] As described above, by using an adhesive capable of achieving the hot peel strength, elongation rate, and elongation recovery rate defined in the present invention for the overlapping portion where the tightening part 2 includes at least the body fabric 4 and the overlapping fabric 5, and combining the linear adhesion 10A and the dot adhesion 10B, it is possible to provide clothing that is comfortable to wear and has a good appearance even when using materials such as low-grammage meshes.
