However, when the water is wetted by sweating or the like, the conventional knitted fabric adheres to the skin and causes an unpleasant feeling, and has a problem that the drying speed is slow. In order to solve the aforementioned problems, there has been a gas permeable self-adjusting braid which has an increased gas permeability when water is wet and which has reduced gas permeability when dried. 20 When wearing a garment made of the aforementioned woven fabric and moistened by sweating, the breathability is improved and the moisture retained in the garment is quickly dried, and after drying, the breathability of the garment is lowered, and the garment is kept warm. The effect is improved, so that the feeling of the skin of the clothes can be maintained in a good state regardless of sweating or sweating. For example, Japanese Laid-Open Patent Publication No. 2003-41462 (Patent Document No.) discloses a composite fiber (A) which is joined by a sulfonic acid group-containing denatured polyethylene ester, a lanthanum or the like, and a size pair. The gas permeable self-adjusting braid composed of the fiber (B) whose temperature change does not substantially change, and the gas permeability of the knitted fabric is more reversibly improved when it absorbs moisture than when it is dried, but its gas permeability is improved. The amount of change is not practical. Further, Japanese Laid-Open Patent Publication No. Hei 10-77544 (Patent Document 2) discloses a woven fabric using a hygroscopic polymer (for example, a copolymerized polyvinyl ester polymer and a polyether ester copolymerized with a hydrophilic compound). The guanamine polymer or the like is formed and includes a synthetic multifilament heated to have a coefficient of 6800 to 26,000 Å, and the content of the synthetic multifilament is 30% by weight or more. Further, Japanese Laid-Open Patent Publication No. 2002-180323 (Patent Document 3) discloses a knit fabric in which a cellulose acetate fiber is used (when the humidity is 95% or more, a crimping ratio of less than 10% is exhibited, and humidity is exhibited. At 65%, it has a crimp ratio of 15 to 20% and a crimp ratio of 25/25.4 mm or more, and has a crimp ratio of 20% or more when the humidity is 45% or less. The woven fabric disclosed in the above Patent Documents 2 and 3 is improved in gas permeability by moisture absorption, but the amount of change in gas permeability is not practical, and therefore it is desirable to have a gas permeable self-adjusting woven fabric having a larger change in gas permeability. .

C. BEST MODE FOR CARRYING OUT THE INVENTION The preferred embodiment of the present invention comprises a crimped composite fiber comprising a crimped conjugate fiber which is moisturized by water and which is composed of a polyester resin component and a polyamide resin component. And has a side-by-side or eccentric core-sheath type composite fiber structure. In the case of the parallel type composite fiber, for example, in the case of having a substantially circular cross-sectional shape as shown in Fig. 1, the portion 1 composed of the polyester resin component and the portion 2 composed of the polyamide resin component are juxtaposed. The relationship is joined and stretched along the long axis of the composite fiber to form an integral composite fiber. In the side-by-side type composite fiber shown in Fig. 2, the cross-sectional shape thereof is elliptical in shape, and in this case, it is preferable that the portion 1 and the portion 2 are joined along a substantially long axis of the elliptical shape of the cross section. In the side-by-side type composite fiber having the wearing shape shown in Fig. 3, a portion 1 composed of a polyester resin component and a portion 2 composed of a polyamide resin component are contained, and a part of the surface is 2 The portion 2a is exposed to the outside, and the remaining portion of the peripheral surface 12 1354041 is joined to the portion 1. In Fig. 3, part 1 is shown in a crescent-shaped cross-sectional shape and is composed of a polyester resin component, and part 2 is shown in a substantially circular cross-sectional shape and is composed of a polyamide resin component, but part 1 It may also be composed of a polyamide resin component, and part 2 may be composed of a polyester resin component.

In the eccentric core-sheath type composite fiber having the cross-sectional shape shown in Fig. 4, part 2 is composed of a polyamide resin component and is contained in a portion 1 composed of a polyester resin component, and part 2 The outer peripheral surface is not exposed to the outside, and the center point 1 a of the portion 1 is inconsistent with the center point 2 b of the portion 2 and the mutual shape of the surface is not angular, and the other polygons are formed by the polyester resin: Since the amount of the conjugate fiber included in the woven fabric of the present invention is limited to the one shown in FIGS. 1 to 4, it may be a triangle, a quadrangle, or the like, or may have a hollow portion inside. By. In the side-by-side and eccentric core-sheath type composite fibers, when the 15 parts differ from the polyamide resin component in heat shrinkability, the heat shrinkage fibers of the partial enthalpy and the part 2 exhibit a crimped state. In the cross-sectional shape of the composite fiber of the present invention, the mass ratio of the portion 2 of the composite fiber is preferably 30:70 to 7:3, and the polyester resin component of the first and second layers is more than A polycondensation product of an aromatic component and a diol component composed of one or more kinds of olefinic diols. The acid component is preferably one containing terephthalic acid as a main component, 13 1354041

Further, the diol component is preferably a component such as ethylene glycol or propylene glycol 'butanediol. Further, the copolymerization component is preferably selected from the group consisting of a metal salt group, an alkaline earth metal salt group, and a salt group, and a compound having at least one functional group is preferred. That is, the polyester resin component preferably contains a modified polyester such as a polyvinyl ester 5 copolymer, a polypropylene ester copolymer, and a polybutene ester copolymer, and the copolymers contain and have the aforementioned sulfonate groups. The aromatic dicarboxy group which is a functional group is used as a copolymerization component. Further, the compound for copolymerization having the above sulfonate diol is effective for improving the bonding property of the obtained polyester resin component to the polyamide resin component. 10 The polyester resin component of the crimped conjugate fiber for a woven fabric of the present invention is a polyvinyl ester copolymer which is denatured by the above-mentioned copolymer component containing a sulfonate group, and is excellent in versatility and low in polymer cost. Suitable for use. The aromatic dicarboxylic acid having the aforementioned sulfonate group is, for example, 5-15 sodium sulfonyl isophthalic acid and an ester derivative thereof, and 5-quinoneisophthalic acid and an ester derivative thereof, etc. The hydroxy compound containing a sulfonic acid group is sodium p-hydroxybenzenesulfonate or the like, and among these compounds, 5-sodium sulfonate is preferably used. Further, the copolymerization component content is based on the amount of the acid component of the polyester polymer contained therein, and is preferably 2.0 to 4.5 mol%, and further, the copolymerization component content is less than 2.0 mol%. Although the obtained composite fiber has sufficient performance, in the obtained composite fiber, the interface between the portion composed of the polyester resin component and the portion composed of the polyamide resin component is peeled off. Further, when the content of the copolymerization component exceeds 4.5 mol%, when the obtained unstretched composite fiber is subjected to the elongation heat treatment, the crystallization of the portion composed of the polyester resin component of 14 1354041 is insufficient, and the elongation heat treatment temperature needs to be increased. As a result, it is possible to break the wire often during the elongation heat treatment.

The polyamide resin is used as a polyamide component, and it is not limited to its kind as long as it has a mercapto bond in its 5 main chain, and is not limited to its kind, for example, it contains a rhenium- 4. Among these types, such as Nylon _6, Nylon _66, Nylon-46, and Dylon-12, Cailong·6 and Nylon _66 have excellent versatility, low polymer prices, and manufacturing. The advantages of high step stability and the like are quite suitable for the present invention. 10 The polyester resin component and the polyamide resin component are independent of each other, and may further contain an additive of more than one type, such as a pigment, a delustering agent, an antifouling agent, a fluorescent whitening agent, and a flame retardant. Agent, stabilizer, antistatic agent, light agent, and ultraviolet absorber. The single fiber fineness of the composite fiber and the number of single fibers (single 15 filaments) contained in the crepe yarn are not particularly limited, but the single yarn fineness is preferably in the range of 1 to 10 dtex, and 2 to 5 dtex is more preferable, and the number of fibers of the composite fiber contained in one yarn is preferably from 1 to 200, and more preferably from 2 to 100. Further, in the composite fiber contained in the woven fabric of the present invention, the polyester resin portion composed of the polyester resin component is higher than the polyamide resin component composed of the polyamide resin component. Shrinkage, and high moisture self-expandability. Therefore, once the composite fiber having the side-by-side or eccentric core-sheath type composite fiber structure used in the present invention is heated, since the polyamidamide resin portion 15 1554041 is more strongly shrunk than the polyester resin portion, shrinkage can be found. The resin portion having a large amount is located on the inner side, and the resin portion having a small amount of shrinkage is located on the outer crimping structure. In addition, when the yarn containing the un-crimped fiber is heated and the crimp is found on the composite fiber, the obtained yarn containing the composite fiber has a southerly fluffiness than the yarn without the crimped 5 composite fiber. 'And its apparent yarn length is shortened. When the crimped composite fiber used in the present invention is wetted by water, the polyamid resin portion in the crimped composite fiber absorbs a larger amount of water than the polyester resin portion, and the display is higher. Self-extension value. (In general, the self-elongation of the polyester resin portion by water wetting is close to ίο 〇.) Therefore, the crimp ratio of the water-wet crimped composite fiber is lower than that of the dry crimped composite fiber. The apparent length of the water-wet crimped composite fiber is also greater than the apparent length of the dried crimped composite fiber. In addition, when the water-wet crimped composite fiber is dried, the polyamide resin portion is dehydrated and shrunk, but the polyester resin portion has almost no dimensional change, so in the dry crimped 15 composite fiber, the crimp ratio thereof Will return to its original state, and its apparent length will also return to its original length. As described above, the crimped composite fiber contained in the woven fabric of the present invention reduces the crimp ratio by water wetting, increases the apparent length of the fiber, and restores the crimp ratio and the apparent length by drying. Therefore, the woven fabric comprising the yarn of the crimped conjugate fiber having the above-mentioned 20 characteristics, wherein the crimping rate of the rewound fiber is lowered by the wetting of the water, and the length of the yarn containing the crimped conjugate fiber is increased, and The gap of the sliver in the braid is increased, so that the area is enlarged and the gas permeability is improved. The gas permeability of the aforementioned woven fabric can be measured in accordance with JIS L 1096-1998.6.27 ιΑ 16 1354041 (Frazil-type gas permeability tester method). In the bat fabric containing the crimped conjugate fiber of the present invention, it is important that the gas permeability when the water is wet is higher than the air permeability when it is wet, and the gas permeability when the water is wet is the gas permeability during drying. For the reference, it is better to use a gas with a height of 5 higher than that of the lining, and Μ is higher than I5·. Better. Gas permeability change rate (%) = [(water wet sample gas permeable gas soil)] (dry sample gas permeability) ><10 〇 The aforementioned dry sample means the temperature 2 (rc, humidity 65% environment) After being placed for 24 hours, the water-wet sample is referred to as "immersed in water at a temperature of 2 hours" and pulled up by water, and within 60 seconds after pulling up, at a temperature of 3 〇. In the air of °C and humidity 9〇%rH, sandwiched between i and filter paper, and apply a pressure of 49〇N/m2 (5〇kgf/m2) to the sample for 1 minute, and gently remove the above sample. The moisture in the process is modulated. When the gas permeability change rate is less than 30%, when the clothes containing the knitted fabric of the water-wet 15 are worn and sweating, the breathability of the clothes may be insufficient, and at this time, the user may feel unventilated or stuffy due to the clothes. sense. The content of the crimped conjugate fiber contained in the woven fabric of the present invention is preferably 10 to 100% by mass, and the content is preferably 4 〇 to 1% by mass, and when the content is less than 10% by mass. The effect of crimping the composite fiber, that is, the wetting of the water of the knitted fabric of 20, drying to obtain an increase in gas permeability <__> reduction of the reversible change may be insufficient. In the woven fabric of the present invention, the crimped composite fiber is contained in a yarn of a woven fabric of 17, and the crimping ratio of the crimped conjugate fiber is lowered by water wetting, thereby containing the crimped conjugate fiber. The apparent length of the sliver is increased, and as a result, the area of the braid is enlarged and the gap of the sliver is increased. As a result, the air permeable void area and air permeability are increased. 5 According to the reduction or increase of the crimping property of the crimped composite fiber, the yarn containing the aforementioned crimped composite fiber can effectively increase or decrease the apparent length thereof, whereby the yarn is 0 to 300 T/m. It is preferred that the number of untwisted yarns or weak crepe yarns is particularly good, especially those without crepe yarns, in order to increase or decrease the permeability of the woven fabric efficiently. Once the number of turns exceeds 300 T/m, since the crimped composite fibers in the yarn 10 will mutually restrict their deformation, when the water is wet or dry, the crimping rate of the composite fiber also changes, so the yarn table There is also a limit to the change in length, which in turn limits the change in the permeability of the braid. Further, in the yarn containing the crimped fiber, interlaced air plus 15 and/or false twist crimping may be applied. At this time, the number of interlacing fibers in the sliver is about 20 to 60/m. It is better. The yarn containing the crimped conjugate fiber may further contain other fibers different from the crimped conjugate fiber, and the other fiber may be selected from the non-crimped fiber and the aforementioned DCF-HCFi value. Less than 10% of the fiber 20 dimensions. Further, the type of the polymer constituting the other fibers is not particularly limited, and examples thereof include polyesters such as polyvinyl ester, polytrimethylene ester, and polybutenyl ester, and polyamines such as Nylon-6 and Nylon-66. Polyolefins such as polyethylene and polypropylene, acrylic acid, para or meta-aramid, and such denatured polymers. Further, the other fibers may be selected from natural fibers, regenerated fibers, semi-synthetic fibers, and the like, which are suitable for clothing fibers, such as dimensional stability in wetness and phase compatibility with fibers (mixing properties, blending). The fiber/interlacing property, dyeing property, and the like are advantageous, and it is most suitable for the fiber composed of polyacetal, polypropylene acrylate, polybutylene, or denatured polyester which is copolymerized with the copolymerized component. Further, the single fiber fineness of the other fibers and the number of single fibers (the number of filaments) contained in the W are not particularly limited, but the single fiber fineness is in the range of (U to 5 dtex (more preferably 0.5 to 2 dtex). It is better, and the number of single fibers contained in the crepe bar is ~200 (more preferably 3 (M(8)) is better to improve the moisture absorption of the woven fabric, and to improve the efficiency efficiently. In addition, it is also possible to apply interlaced air to the other fibers and/or a false twist crimping process to form an interlacing number of about 2 to 60/m. In the woven fabric, the crimped conjugate fiber and the other fibers are each composed of one or more types of yarns, and the yarn yams may be interlaced, or the crimped conjugate fiber and the other fibers may constitute a mixed yarn. It is also possible to use the air-mixing method. Alternatively, the crimped composite fiber yarn and the other fiber yarns may form a twisted yarn or a blended yarn, and a composite false twist crimping process or yarn may be formed. There is no limitation on the number of braided tissues and braid layers of the inventive braid, and the braided tissue Such as: plain weave, twill weave, woven weave and other weave, jersey, circular rib knit, alternating tuck knit, add yarn weaving, single comb 栉 平 flat organization, double comb 栉 平 flat organization, etc. Further, the weave structure includes a single layer structure and a multilayer structure of two or more layers. In the woven fabric of the present invention, in order to ensure the detachability of the crimped fibers in the woven fabric, deformation versatility (volume change possibility) Therefore, it is preferable to have a tendency to expand and contract in the direction of the warp direction and the 1354041 (or) weft direction, and it is preferable that the stretch ratio is more than 20% or more, and 25 to 15% by weight. More preferably, in the woven fabric of the present invention, the conjugate fiber contained in the woven fabric has a crimped structure in which the crimping property is manifested, and the crimping ratio of the composite 5 fiber when dried is DCf (%). , the shrinkage rate when moisture absorption is He〆.〆.) When 'DCf - HCf g 1 〇 (%) (again 5〇(%) 2 DCf — HCf ^ i 〇 (%) is better) It is extremely important, and when DCf_HCf is less than 1〇%, it may not be able to lift more efficiently when it is wet. It is not applicable. Here, the crimping ratio of the crimped composite fiber in the braid is measured by the following 10 methods: First, the braid is placed in the air at a temperature of 20 ° C and a humidity of 65% RH. After 24 hours, a small piece (n number = 5) of 30 cm x 30 cm in the same direction as the woven fabric was cut out from the woven fabric. Then, the conjugate fiber was taken out from each piece, and 1.76 mN/dtex (200 mg/) was applied to the conjugate fiber sample. De) The load was measured to measure the fiber length LOf, and a load of 15 〇.〇176 mN/dtex (2 mg/de) was applied after 1 minute of de-weighting to measure the fiber length Llf. Then, the composite fiber sample was impregnated at a temperature of 30 2 ° water in °C, and pull the sample from the water, and within 60 seconds after pulling, in the air at a temperature of 30 ° C, humidity 90% RH, sandwiched between a pair of filter paper, and After applying a pressure of 0.69 mN/cm 2 to the above sample for 5 seconds, the water was gently wiped off from the sample for 20 minutes, and a load of 1.76 mN/dtex (200 mg/de) was applied to the sample to measure the fiber length LOf'. And after removing the weight for 1 minute, a load of 0.0176 mN/dtex (2 mg/de) was applied to measure the fiber length Llf'. Based on the above measurement results, the crimp ratio DCF (%) at the time of drying and the curl ratio HCF (%) of water wetness were calculated by the following formula. 20 Crimping rate DCF (%) = ((LOf - L1 f) / LOf) when dry 100 Crimping rate HCF (%) = ((LOf '-L1 f ') / L0f,) x 100 by moisture absorption The DCF and HCF calculate the difference (DCF - HCF), and the n number is 5 ' at this time and the average value is calculated. 5 The woven fabric of the present invention can also be processed by applying a water absorbing agent, and by applying water absorbing treatment to the woven fabric, the gas permeability can be easily improved even with a small amount of sweat, and the water absorbing treatment applied can be generally water absorbing processing. A water-absorbent processing agent such as polyethylene glycol diacrylic acid and a derivative thereof, or a polyethylene-Sb-ethylene-ethylidene copolymer is attached to the woven fabric, and the water absorbing agent 10 is attached with a weight of 0.25 to the woven fabric. 0.50% by weight is preferred. In addition, the water absorption processing method includes: a dye bath processing method in which a water absorbing processing agent is mixed in a dyeing liquid during dyeing processing, a method of immersing in a water absorbing processing liquid before dry heat and condensing, and a method of rolling by a roll, gravure coating method The stencil printing method and the like use a coating processing method or the like. Further, the water-repellent woven fabric of the present invention may be subjected to a water-repellent process, and a general water-repellent treatment may be applied. For example, the method disclosed in Japanese Patent No. 3,133,227 and Japanese Patent Publication No. Hei. That is, a commercially available fluorine-based water repellent (for example, Asahi Glass Co., Ltd. (ASAHI GLASS Co., Ltd., 7 Ganzifang-KLS-317) is used as a water repellent, and trimeric 20 cyanide is mixed as needed. The amine resin and the catalyst are used to prepare a processing agent having a water repellent concentration of about 3 to 15% by weight, and the method for treating the surface of the knitted fabric by using the processing agent at a pressure absorption ratio of about 50 to 90% is further processed by a processing agent. The method of the surface of the fabric may also be, for example, a pressure suction method, a spray method, etc., wherein the pressurization method in which the processing agent can be impregnated into the inside of the braid is optimal. 21 1354041 Further, the aforementioned pressure suction ratio refers to a relative processing agent. Weight ratio (%) of the weight of the fabric (before the processing agent). The water repellency of the woven fabric after water repellency is better than 4 points or more according to the JIS L 1092 6_2 (spray test) measurement, and 5 points (highest score) 5 is better. In the water-repellent woven fabric, since the shrinkage ratio of the composite fiber contained in the woven fabric is efficiently reduced during moisture absorption, the length of the composite fiber yarn becomes longer, and the void in the woven fabric becomes larger and the gas permeability is improved; On the other hand, since the conjugate fiber shrinkage rate is increased during drying, the length of the composite fiber yarn becomes 10 short. As a result, the voids in the woven fabric become short and the gas permeability is lowered. The woven fabric of the present invention can also be a dyed processor, and Hereinafter, the dyeing processing conditions and the like will be described in detail. In the present invention, for example, (1) a multilayer structure knitted fabric having two or more layers of a woven fabric, and at least one layer of the knitted fabric contains a composition 15 30% by weight or more of the total fiber weight of the composite fiber of the composite fiber ('2) The composite fiber and the other fiber are formed into a composite yarn of a circular structure' (3) The composite fiber is blended with other fibers and knitted (4) the woven fabric of the woven fabric and the other woven fabrics, and the braided yarns of the other woven fabrics are arranged in a staggered manner or interlaced with each other. 5) The woven fabric includes the conjugate fiber and the other fiber, and the 幵v is a core-sheath type composite yarn in which the conjugate fiber is disposed in the forbearing portion and the other fibers are disposed in the sheath portion. When the composite fiber and other fibers and food are dry, when the fiber length of the composite fiber is (A), and the fiber length of the other fiber 22 1354041 is (B), in the case of A < B, the gas permeability of the wet eye can be Conveniently, in the case of A > B or A = B, when the folding fiber is reduced due to wetting and the stretch ratio is reduced, the other fibers cannot be stretched because there is no excess amount, so the void ratio of the knitted fabric is lowered. , when it is wet, the gas permeability can not be improved.

Here, the measurement of the fiber length is carried out by: firstly, the braid is at a temperature of 20. (:, after standing in the air with a humidity of 65% RH for 24 hours, a small piece of 3〇cmx30cm (n number=5) was cut out from the knitted fabric. Then, the composite fiber yarn and other pieces were taken out from each small piece. The fiber sliver 'measures the fiber length A (mm) in the composite fiber sliver and the fiber length B (mm) in the other fiber sliver. At this time, if it is a non-elastic yarn, apply 1,76 mN/dtex (200 mg/ The load of de), if it is an elastic yarn, is measured by applying a load of 0.0088 mN/dtex (lmg/de). Here, the composite fiber yarn strip taken out from the small piece and the other fiber yarn strips need to be in the same 15 directions in the braid. For example, if the composite fiber sliver is taken out from the warp (weft) of the fabric, it is necessary to take out the other fiber sliver from the warp (weft). In addition, if the composite fiber sliver is used as a composite with other fiber slivers. When the yarn constitutes a woven fabric, the composite yarn (n number = 5) is taken out from the cut piece (30 cm x 30 cm), and then the composite fiber yarn is taken out from the composite yarn and the other fiber yarns 2 〇 and measured in the same manner as described above. As mentioned above, in composite fiber slivers The method for providing the difference in fiber length between the fiber slivers can be exemplified by the following methods. For example, when a composite fiber sliver and other fiber slivers are used, and the knit fabric is knitted, the boiling water shrinkage ratio of other fiber slivers is adjusted. It is a method of 5% or less (more preferably 10% or less) 23 1354041, or a method of super-feeding other fiber slivers in the composite processing of composite fiber slivers and other fiber slivers, etc. In the woven fabric, in order to ensure the movability (coiling change) of the composite fiber in the woven fabric, the mass per unit area is preferably 300 g/m 2 or less (more preferably 5 100 to 250 g/m 2 ). The woven fabric of the present invention can be easily obtained. First, a copolymer having an intrinsic viscosity of 〇.3〇~〇43 (a gas phenol solution is measured as a solvent and measured at 35 C) has a 〇~4.5 mol% of 5-sodium. Denatured polyester of sulfoisophthalic acid, and polyamine which has an intrinsic viscosity of 1.0 to 1.4 (m-phenol is a solvent and measured at 30 10 C), and is used for spinning with a side-by-side or eccentric core-sheath type composite fiber. The wire nozzle performs the melt compound spinning. At this time, It is particularly important that the intrinsic viscosity of the polyester resin component is 0.43 or less. Further, when the inherent viscosity of the polyester resin component is more than 0.43, the viscosity of the polyester component is increased, and the physical properties of the composite fiber are close to the polyester individual yarn, so the present invention cannot be obtained. The object of the invention is not suitable for weaving 15; relatively, once the inherent viscosity of the polyester resin component is less than 0.30, the melt viscosity is too low, which may result in a decrease in yarn making property and an increase in fluff generation and quality and production. The spinning nozzle used in the melt spinning is separated into the discharge holes on the high viscosity side and the low viscosity side, as shown in Fig. 1 of JP-A No. 2144518, and is preferably lowered. A spinning nozzle that spouts at a high viscosity side (increasing the discharge cross-sectional area). Further, it is preferable to discharge the pores through the high-viscosity side with the dazzling polyester, and to melt the polyamine to pass through the low-viscosity side discharge hole and to cool and solidify. In this case, the weight ratio of the polyester component to the polyamine component is preferably in the range of 30:70 to 70:30 (more preferably 40:60 to 60:40) as described above. 24 1354041 In addition, after the melt composite spinning, a partial extension method of stretching after the temporary winding may be employed, and a direct extension method of the extension heat treatment without temporary winding may be employed. In this case, the spinning/extension condition is a general condition. For example, in the case of the direct extension method, after spinning in about 1 to 3500 m/min, the winding is continuously extended at a temperature of 5 1 〇 0 to 15 〇 ° c. In addition, the stretching ratio can be appropriately selected to form a cut length of 10 to 60% (preferably 20 to 45%) of the composite fiber finally obtained, and the cutting strength is about 3. 〇 to 4.7 cN/dtex. By. Here, the above composite fiber is preferably one which satisfies the following requirements (1) and (2) at the same time. 10 (1) The composite fiber crimp ratio DC is 1.5 to 13% (more preferably 2 to 6%). (2) The difference between the crimp ratio DC and the composite fiber crimp ratio hc when water is wet (DC-HC) is 0.5% or more (more preferably 1 to 5%). However, 'drying means the state in which the sample is allowed to stand in the environment of temperature 2 (TC, humidity 65% RH for 24 hours), on the other hand, when wet, it means that the sample is immersed in water at a temperature of 30 ° C for 2 hours. After a short period of time, the crimping rate DC during drying and the crimping rate HC during wetting were measured by the following methods. First, 'Use the frame of the frame l_125m to apply the load: 49/50mN 20 x9x The total count (O.lgfx total denier) and the yarn is wound at a fixed speed, and the number of rolls is made: 10 twists, and the total number of 49/2500mNx20x9x is applied to the strands to form a 2-layer round. (2mgx20x total Danny) was placed in boiling water for 30 minutes, and after the boiling water treatment, it was dried for 30 minutes using a dryer of i〇〇°c. Then, the initial load was applied again and placed at 16 °C. Dry heat in the middle 25 1354041

5 points. The initial load was removed after the dry heat treatment and was at a temperature of 2 Torr. After being placed in a humidity of 65% RH for more than 24 hours, load the weight of the initial load and the total weight of 98/50mNx20x9x (0.2gfx20x total denier) to measure the skein length L0' and then remove only the heavy load. The length of the twisted yarn 5 is measured after the weight is removed by 1 minute. Further, the skein was subjected to an initial load and immersed in water at a temperature of 2 ° C for 2 hours, and then taken out, and the water was gently wiped off by a transfer paper at a pressure of 6969 mN/cm 2 (70 mgf/cm 2 ). Thereafter, the initial load and heavy load of the load were measured to measure the skein length L0', and then only the heavy load was removed to measure the skein length L1' after the weight was removed by one minute. From the above measured values, the crimping ratio (DC) at the time of drying 10, the crimping ratio (HC) at the time of wetting, and the crimping rate difference (DC-HC) at the time of drying and wetting were calculated by the following calculation formula. Crimping rate DC (%) = ((L0 - L1 ) / L0) x 1 The curling rate of wet water is HC (%) = ((L0, L1,) / L0,) χ 1 〇 It is preferable that the composite fiber crimp ratio HC is 0.5 to 10.0% (more preferably 15 1 to 3%) in the case of the above-mentioned wetting. Here, if the composite fiber crimp ratio DC is less than 1.5% when dry, the amount of change in the curling property of the knitted fabric may become small as the amount of curl change during wetting becomes small; When the crimp ratio of the composite fiber is higher than 13%, it is difficult to produce a curl change when wet because the crimp is too strong, and the change in the gas permeability of the knitted fabric may also be small. Further, if the difference (DC - HC) of the composite fiber crimp ratio HC during drying is less than 0.5%, the amount of change in the gas permeability of the knitted fabric may be small. Then, the conjugate fiber is used alone or after other fibers are used to knit the woven fabric, and then the crimping of the 26-composite weave is revealed by heat treatment such as dyeing. Here, when knitting into a woven fabric, as described above, it is important to use 10% by weight (preferably 4% by weight) based on the total weight of the bat fabric on the basis of weight, and the woven structure is not particularly limited. Appropriately select the aforementioned. The temperature of the dyeing process is 100 to 140 ° C (more preferably 110 to 135 ° C), and the time is preferably in the range of 5 to 40 minutes of the top temperature duration, and under such conditions, When the knitted fabric is dyed, the composite fiber is curled due to a difference in heat shrinkage between the water ester component and the polyamide component. At this time, by selecting the polymer as the polyester component and the polyamide component, a crimped structure in which the polyamide component is located inside can be formed. Dry heat finishing is generally applied to the dyed processed fabric. At this time, the dry heat final setting temperature is 120 to 2 Torr. 0 (again 140~18 (TC is better), the time is preferably in the range of 1~3 minutes. As a result, if the dry heat final condensation temperature is lower than 120C, it is easy to leave the wrinkles generated during dyeing processing. Pleating, in turn, the dimensional stability of the finished product may be deteriorated; in contrast, if the dry heat final setting temperature is higher than 200C, the composite fiber crimping which appears when the color processing is performed may be lowered, or the fiber hardening may cause texture touch change. In addition, in the woven fabric of the present invention, in addition to the foregoing processing, it can also be applied to a velvet blanket with a conventional method, an ultraviolet shielding or an antibacterial deodorant, an insect repellent, a luminous agent, and a return. Various processes such as a reflector, an anion generator, a water absorbing agent, etc. The woven fabric of the present invention reduces the volume _ by the water of the crimped conjugate fiber contained in the woven fabric, thereby, the living (four) high domain The characteristics of the gas permeability of the article are at least a part of the clothes such as clothes, clothes, clothes, and underwear 1354041. The clothes of the present invention are the above-mentioned crimping compound containing water moisturizing and improving gas permeability. Woven fabric, characterized by The size thereof is reversibly expanded by water wetness, and the gas permeability is improved, and the gas permeable effect is exhibited. 5 The clothes of the present invention include clothes for outerwear, clothes for sports, clothes for underwear, etc. In a preferred embodiment of the garment of the present invention In the case where the size is not changed by the wetness of the water, and the size is reversibly expanded by the water (we reversibly enlarge the area), in which the area is enlarged by the wetness of the water 10 is partial. Therefore, the overall size of the clothes will not be excessively enlarged, and the gap between the clothes and the wearer's skin will not be excessively enlarged, that is, wearing the clothes of the foregoing aspect, and when the wearer is sweating, moist and moist with sweat (size) The increased portion expands outward toward the outside, and increases the gap between the wearer's skin and the portion, so as to achieve an increase in the gas permeability of the wet portion, and further increase the gas permeability of 15 liters. In the clothes of the present invention, the size is not changed by water wetting. Partially refers to the use of water to create a portion of the area change rate of less than 5%, and the size of the use of water to wet the change means that the use of water is wet A portion where the area change rate is 5% or more is produced. Further, the change in the area ratio of the clothes is measured by the following method. 20 The woven fabric is left in an environment of a temperature of 20 ° C and a humidity of 65% RH for 24 hours (hereinafter referred to as drying). After the time, the sample in the same direction as the braid (cut 20 cm x 20 cm square) was used as the area (cm2) when dry. On the other hand, the sample was immersed in temperature 3 (5 minutes in TC water). After (hereinafter referred to as wet time), and pull up the sample, and within 6 seconds after pulling up, clamp the sample of 13 1354041 between two pieces of filter paper, and increase the pressure of 490N/m2 (50kgf/m2) After 1 minute' removal of the moisture remaining between the fibers, the area of the wet sample (cm2) was measured. Further, the case where the area was reduced by the wetness of the water was also included in the case where "the size did not change relative to the wetness". 5 Area change rate (%) = ((area when wet) 1 (area when dry)) / (area when dry) X100

In the above aspect of the garment of the present invention, the woven fabric formed into a portion whose size is not wetted by water may be selected from organic natural fibers such as cotton, wool, hemp, organic synthesis such as polyester, lons, and polyolefin fibers. Organic semi-synthetic fibers such as fibers, cellulose acetate fibers, and organic regenerated fibers such as mucilage fibers are not particularly limited. Among them, polyester fiber is preferred in terms of fiber strength and usability. The polyester fiber is made of a dicarboxylic acid component and a diol component. It is preferred that the dicarboxylic acid component is mainly terephthalic acid, and the diol component is preferably one or more selected from the group consisting of 15 ethylene glycol, trimethyl glycol, and tetramethyl glycol. Further, the third component other than the above-mentioned two retinoid components and the monool component may be contained in the polyg. The third component may use a cationic dye-stainable anion component such as sodium sulfonate; a dicarboxylic acid other than terephthalic acid such as isophthalic acid, naphthalene dicarboxylic acid, adipic acid, bismuth An acid; and a diol compound other than the olefinic diol, such as diethylene glycol, one or more of ethylene glycol, bisphenol A, and bisphenol sulfonate. In the fiber whose size is not changed by water wetting, it may also contain a delustering agent (titanium dioxide), a micropore-forming agent (organic sulfonic acid metal salt), a coloring preventive agent, a thermal stabilizer, and a flame retardant (three-oxidation) as needed. Citrate), a fluorescent whitening agent, an anti-29 1354041 electric agent (% acid metal salt), and a moisture absorbent (one or more kinds of polyhydroxy olefinic inorganic particles).

The fiber type whose size is not changed by water wetting is not particularly suitable for long fibers (multifilament) or short fibers, and is preferably a long fiber having a soft touch. In addition, it is also possible to apply a general false twist, a crepe, a six-woven air processing 'X, although the fiber fineness is not particularly limited, but the softness of the single fiber fineness (M~3dtex, monofilament number pure) G, the total fineness of 30~3_teX is better. In addition, the shape of the single fiber carrier surface is not limited to two, except for the circular cross section, it may be triangular, flat, cross, hexagonal, or hollow. The cross-sectional shape.

The above-mentioned knit structure of the monool), the antibacterial agent, and the 10th dimension which is not wetted with respect to water is also not particularly limited, and may be any. For example, the weaving structure of the fabric may be a three-dimensional structure such as plain weave, twill weave, and woven weave, a changeable structure, a twill weave, and the like, a vertical double-layer structure, a horizontal double-layer structure, and the like, and a vertical double velvet structure.

In the foregoing aspect of the garment of the present invention, the size is reversibly enlarged by the wetted portion, and the other portion is composed of a braid having a size which does not change with respect to the aforementioned wetting. Further, it is preferable that the size is reversibly enlarged by moistening to a portion which is more sweaty. For example, the knitted fabric portion 30 is preferably disposed in the pattern of Fig. 5 to display the knitted fabric portions 6 and 8 of the chest 7 which are schematically displayed on the front face 5 and the sixth figure, and the side body portion 9 which is schematically shown in Fig. 7.
