Description

Technical Field

[0001] The present invention relates to clothing fabrics and clothing containing the same.

Background Art

[0002] In autumn and winter seasons, because it is chilly, in order to improve the warmth comfort, people often wear clothing with excellent moisture absorption and heat generation properties. However, when exercising for a certain period of time, as the muscle temperature rises, the body temperature also rises, and the body needs to dissipate heat, resulting in sweating. Generally, rayon and cotton are used as fibers with excellent moisture absorption and heat generation properties, but most of these fibers have a high moisture absorption and heat generation capacity, so most of the materials have a large amount of use per unit area. Since these fibers are easy to hold water, when the fabric becomes wet due to sweating, it is difficult to dry, and it is likely to cause an uncomfortable feeling of cold sweat. On the other hand, there are also materials that use highly moisture-absorbing and heat-generating crosslinked acrylate fibers and combine them with other functional yarns while minimizing the amount of use, thereby improving the sweat treatment performance of the fabric. Compared with fabrics made of rayon or cotton, the cold caused by sweat is reduced, but compared with fabrics made of general synthetic fibers, it is still easy to feel cold sweat. As a prior art, Patent Document 1 proposes a heat-insulating fabric obtained by interweaving a synthetic fiber multifilament yarn containing far-infrared radioactive fine particles and a moisture-absorbing and heat-generating spun yarn. Patent Document 2 proposes a laminated fabric obtained by laminating a knitted fabric made of a yarn mixed with wool and acrylate fibers and a water-permeable and waterproof film. Patent Document 3 proposes a knitted fabric obtained by interweaving an elastic yarn containing hygroscopic fine particles and a synthetic fiber filament yarn. The applicant of the present application proposes in Patent Document 4 tights etc. in which a moisture-absorbing and heat-generating fabric is partially arranged.

[0004] However, the aforementioned conventional clothing fabrics had the problem of causing chills from sweat when exercising, and there was a need for fabrics with even higher thermal comfort.

[0005] To solve the aforementioned conventional problems, the present invention provides a clothing fabric and clothing containing the same, which have good skin-hugging properties even when sweating during exercise, prevent chills from sweat, and have high thermal comfort suitable for sports in cold weather. [Means for solving the problem]

[0006] One embodiment of the present invention is a garment fabric comprising a synthetic fiber multifilament yarn and a long and short composite spun yarn containing moisture-absorbing and heat-generating fibers, At least the long and short composite spun yarns are arranged on one side of the aforementioned fabric, and the surface has an uneven structure. The present invention relates to a garment fabric in which at least the synthetic fiber multifilament yarn is arranged on the other side of the aforementioned fabric.

[0007] Another embodiment of the present invention relates to a garment comprising the above-mentioned garment fabric, wherein the surface on which the long and short composite spun yarns are arranged and which has an uneven structure is positioned on the skin side. [Effects of the Invention]

[0008] The garment fabric of the present invention comprises synthetic fiber multifilament yarn and long and short composite spun yarn containing moisture-absorbing and heat-generating fibers. At least the long and short composite spun yarn is arranged on one side of the fabric and has an uneven structure, while at least synthetic fiber multifilament yarn is arranged on the other side.

Mode for Carrying Out the Invention

[0010] The present invention is a clothing fabric containing a synthetic fiber multifilament yarn and a long-short composite spun yarn containing a moisture-absorbing and heat-generating fiber. Examples of the synthetic fiber multifilament yarn include polyester (PET), nylon, etc., and polyester (PET) multifilament yarn is preferred because of its hydrophobicity and easy drying property. The moisture-absorbing and heat-generating fiber is not particularly limited, and examples thereof include cellulose fibers such as cotton, rayon, acetate, and triacetate, nylon fibers, and acrylate-based fibers. Preferred is a crosslinked acrylic fiber having a high official moisture regain. Examples of the crosslinked acrylic fiber include the product name "Bress Thermo" of the present applicant. This "Bress Thermo" has high moisture-absorbing and heat-generating properties as well as high water-absorbing properties, and has the property of easily absorbing sweat from the skin surface and releasing it from the outer air surface.

[0011] The long-short composite spun yarn preferably contains one or more fibers selected from the group consisting of hydrophobic fibers and water-repellent fibers, which makes it easier for moisture on the fabric surface to move. Examples of hydrophobic fibers include hydrophobic fibers such as polypropylene fibers, polyethylene fibers, and polyester fibers. Examples of water-repellent fibers include fibers obtained by water-repellent treatment of polyester fibers. It is preferable to apply a non-fluorine-based water-repellent agent to the filament fiber yarns constituting the long-short composite spun yarn. Types of non-fluorine-based water-repellent agents may include urethane-based, hydrocarbon-based, silicone-based, acrylic-based, etc. Conventional fluorine-based water-repellent agents are excellent in water repellency and durability but have a large environmental impact and are subject to usage restrictions, so it is preferable to use non-fluorine water-repellent agents. The water-repellent treatment may be performed on the fibers or yarns, or on the knitted fabric. The water-repellent treatment is not particularly limited. For example, a method of winding the yarn into a cheese shape, immersing it in a water-repellent treatment agent, and then subjecting it to a crosslinking reaction by dry curing; a method of repeatedly applying a water-repellent treatment agent to the yarn on these machines using a false twisting machine or a spinning machine equipped with a water-repellent treatment agent application facility and then subjecting it to a crosslinking reaction by dry curing; a method of providing a water-repellent treatment agent application facility on a spinning and drawing machine at the raw yarn manufacturing stage, applying a water-repellent treatment agent to the yarn on these machines, and then subjecting it to a crosslinking reaction by dry curing, etc. The application amount of the water-repellent agent is preferably 1 to 10% owf (abbreviation for on the weight of fiber). The water-repellent performance of the water-repellent fiber is preferably a grade of B or higher, particularly preferably grade A, when tested according to the AATCC193 method in the state of being knitted into a circular knit.

[0012] On one side of the fabric for clothing, long-short composite spun yarns containing moisture-absorbing and heat-generating fibers are relatively more arranged compared to the other side and have an uneven structure. When this side is placed on the skin side, it generates heat due to the moisture-absorbing and heat-generating fibers, and gaps are formed due to the uneven structure, resulting in good skin separation even when sweating, no cold sweat, and it becomes a fabric suitable for sports in cold seasons.

[0013] On the other side of the garment fabric, a relatively larger amount of synthetic multifilament yarn is arranged compared to the other side. This makes it easier to dry even when wet with sweat.

[0014] The long-short composite spun yarn is preferably a spun yarn obtained by spinning and twisting a roving of a blend of highly crosslinked acrylic staple fibers and synthetic fibers with a synthetic fiber multifilament yarn. The blending ratio of highly crosslinked acrylic staple fibers and synthetic fibers is preferably 1 to 50% by mass of highly crosslinked acrylic staple fibers and 50 to 99% by mass of synthetic fibers, and more preferably 5 to 40% by mass of highly crosslinked acrylic staple fibers and 60 to 95% by mass of synthetic fibers. The long-short composite spun yarn can be a spinning and twisted yarn produced by spinning a ring spinning machine or a twisted yarn produced by twisting spun yarn and filament yarn with a twister, but the spinning and twisted yarn is preferred. Since the long-short composite spun yarn is wound around a blend of highly crosslinked acrylic staple fibers and synthetic fibers, it is less prone to pilling even after long-term use and has good washability. Furthermore, it is preferable to arrange the synthetic fiber multifilament yarn on the outside so that it is exposed as much as possible on the surface side of the long-short composite yarn. By arranging synthetic multifilament yarn on the surface, the contact area between the skin and the highly crosslinked acrylic short fibers, which easily absorb sweat and become moist, is reduced, making it easier to suppress chills caused by sweat.

[0015] The long and short blended spun yarn preferably has a twist coefficient (K) of 2.5 to 3.3, more preferably 2.6 to 3.2, and even more preferably 2.7 to 3.1. However, the twist coefficient (K) is calculated using the following formula. Twist coefficient (K)=t / √S However, t: twist count (twists / inch), S: cotton count (English cotton count) This improves the bulkiness of the yarn. In general short-fiber spun yarns, reducing the number of twists lowers the yarn strength, resulting in decreased durability and production stability. However, because the long-short composite spun yarn of the present invention is compounded with long fibers, the yarn strength does not decrease even when the twist coefficient is reduced. Furthermore, the compounding of long fibers makes it possible to improve the elongation of the yarn. Improved yarn elongation makes it easier to impart stretchability to the fabric, enabling the design of clothing that fits the entire skin surface, thus efficiently managing sweat on the skin surface and making it easier to suppress chills caused by sweat.

[0016] When the garment fabric is considered as 100% by mass, the moisture-absorbing and heat-generating fibers are preferably 1 to 40% by mass, more preferably 5 to 35% by mass, and even more preferably 10 to 30% by mass. Within this range, the moisture-absorbing and heat-generating properties can be effectively utilized to provide warmth even when sweating.

[0017] It is preferable that the long and short composite spun yarn has a higher fineness than the synthetic fiber multifilament yarn. This allows for the formation of an uneven surface on one side of the fabric, which is convenient for facing the skin.

[0018] The long fibers constituting the synthetic fiber multifilament yarn and / or the long and short composite spun yarn are preferably elastic yarns. Elastic yarns include false-twisted yarns, side-by-side conjugate yarns, polyurethane elastic fiber yarns, and knit-de-knit yarns. False-twisted yarns are not particularly limited, but can be produced using false-twisting machines such as spindle type, friction type, and belt-nip type. An example of a side-by-side conjugate yarn is a side-by-side conjugate yarn in which polyethylene terephthalate and polypropylene terephthalate components are extruded from a single spinning die; Toray Lycra Co., Ltd., under the trade name "Lycra T400 Fiber," is commercially available. Knit-de-knit yarn is a yarn made by unraveling knitted fabric. When elastic yarns such as false-twist yarns are used and the resulting fabric is heat-treated, the elastic yarns shrink more significantly relative to the blended roving of highly crosslinked acrylic staple fibers and synthetic fibers. This increases the differential shrinkage between the elastic yarns and the blended roving of highly crosslinked acrylic staple fibers and synthetic fibers, resulting in significant crimping of the long and short composite yarns. This imparts stretchability to the fabric, while simultaneously creating an uneven surface on the surface where the long and short composite spun yarns are arranged.

[0019] The synthetic fiber multifilament yarn is preferably hydrophilic on its surface. Hydrophilicity can be imparted by a water absorption and quick-drying treatment. As an example, the water absorption and quick-drying treatment is preferably a treatment in which at least a portion of the hydrophilic polyester resin processing agent molecules are absorbed into the fiber, and the remainder coats the surface of the polyester fiber to make it hydrophilic. The water absorption and quick-drying agent (hydrophilic polyester resin processing agent) is preferably a processing agent that, like a disperse dye, allows at least a portion of the processing agent to be absorbed (exhausted diffusion) into the polyester fiber. As an example, this hydrophilic polyester resin processing agent is a copolymer in which the terminal groups of polyester groups and hydrophilic groups are linked to each other in a linear structure. It is preferably a block copolymer. The molecular weight is preferably 5000 to 8000, and more preferably 6000 to 7000. The weight ratio of polyester groups to hydrophilic groups is preferably 90 / 10 to 10 / 90, and more preferably 60 / 40 to 20 / 80. Examples of hydrophilic groups include polyethylene glycol, sodium 5-sulfoisophthalate, and trimellitic anhydride, with polyethylene glycol being more preferred. An example of such a processing agent is KMZ-902, manufactured by Takamatsu Oil & Fat Co., Ltd.

[0020] Mass per unit area of ​​clothing fabric: basis weight is 100-300 g / m² 2 Preferably, and more preferably, 110-270 g / m² 2 And more preferably 120-250 g / m² 2 Therefore, it is suitable as lightweight sportswear.

[0021] The uneven surface of one side of the garment fabric preferably has a height difference of 0.40 mm or more between the recessed and raised parts, more preferably 0.45 to 1.5 mm, and even more preferably 0.50 to 1.2 mm. This results in point contact between the skin and the grip, improving skin separation when sweating occurs. Furthermore, the density of the clothing fabric is 0.050~0.170 g / cm³ 3 Preferably, it is 0.060 to 0.165 g / cm³. 3 And more preferably 0.070 to 0.160 g / cm³ 3This results in a lightweight yet bulky fabric.

[0022] Clothing fabrics, in the drop-drop evaluation specified in JIS L 1907:2010 Method A, preferably absorb water within 180 seconds, more preferably 60 seconds or less, even more preferably 40 seconds or less, even more preferably 30 seconds or less, even more preferably 20 seconds or less, and particularly preferably 10 seconds or less. When sweating occurs, the fabric quickly absorbs sweat, improving sweat management. This promotes the evaporation of sweat during exercise when the body needs to dissipate heat, and immediately after exercise when the body is less likely to need to dissipate heat, it reduces the amount of liquid sweat remaining on the skin surface, making it less likely to feel cold due to sweat.

[0023] The fabric of the present invention may be woven or knitted. Woven fabrics are based on plain weave, twill weave, satin weave, modified plain weave, modified twill weave, modified satin weave, variant weave, patterned weave, single overlap weave, double weave, multi-layer weave, warp pile weave, weft pile weave, leno weave, etc. Knitted fabrics include circular knitting, weft knitting, warp knitting (including tricot knitting and raschel knitting), pile knitting, bonded double knitting, etc., and are based on plain knitting, jersey knitting, rib knitting, smooth knitting (double-sided knitting), rib knitting, pearl knitting, denby weave, cord weave, atlas weave, chain weave, insert weave, etc. Among these, knitted fabrics are preferred in order to achieve an uneven structure while maintaining a certain thickness of fabric. Knitted fabrics are preferred, such as warp knitting, weft knitting, and circular knitting of tricot, raschel, etc. Among these, circular double knit, smooth knitting (double-sided knitting), bonded double knitting, etc. The stretchability of the fabric of the present invention was measured in accordance with JIS L 1096 Method A, using a benchtop precision universal testing machine (AUTOGRAPH AGS-X 5kN, manufactured by Shimadzu Corporation), with a tensile speed of 200 mm / min. The sample fabric size was 25 mm in width, 150 mm in length, and a gripping distance of 100 mm. The elongation is preferably 100-250% in the transverse (course) direction and 40-120% in the warp (wale) direction. Furthermore, the tensile modulus (stretch recovery rate) is preferably 30-50% in the warp direction and 15-40% in the transverse direction. This results in desirable characteristics for sportswear that do not hinder human movement.

[0024] The garment of the present invention is a garment comprising the above-mentioned garment fabric, wherein one side of the fabric, which has a textured surface and is arranged with a relatively larger number of long and short composite spun yarns on one side compared to the other, is positioned on the skin side. As a result, the fabric does not separate from the skin well even when sweating during exercise, preventing chills from sweat, making it suitable for sports in cold weather.

[0025] The following explanation will be given using drawings. In the following drawings, the same reference numerals indicate the same object. Figure 1 is a schematic cross-sectional conceptual diagram showing the relationship between a garment fabric 1 and sweat in one embodiment of the present invention. In this garment fabric 1, many long and short composite spun yarns 2 are arranged on the side facing the skin of the human body, and many synthetic fiber multifilament yarns 3 are arranged on the side facing the outside air. Liquid sweat S1 generated from the skin 4 of the human body is absorbed into the layer of long and short composite spun yarns 2 as shown by arrows a1 and a2, then moves to the layer of synthetic fiber multifilament yarns 3 as shown by arrows b1 and b2, diffuses, and evaporates from the surface of the synthetic fiber multifilament yarns 3 as shown by arrows c1-c5. Gaseous sweat S2 generated from the skin of the human body evaporates into the outside air from between the yarns of the garment fabric 1 as shown by arrows d1 and d2. Due to this mechanism, liquid sweat S1 and gaseous sweat S2 generated from the skin 4 of the human body evaporate quickly into the outside air and do not remain on the skin surface, resulting in good skin separation and no chilling from sweat. Furthermore, since the layer of long and short composite spun yarn 2 placed on the side of the human skin has an uneven structure, the fabric 1 makes point contact with the skin 4, and in combination with the cross-sectional structure of the fabric 1 described above, it has good skin separation and does not cause chills from sweat. In order to further emphasize the uneven structure, it is preferable that the yarns other than the long and short composite spun yarn used on the surface where the long and short composite spun yarn is placed are thinner than the long and short composite spun yarn. By using yarns thinner than the long and short composite spun yarn, the difference in height between the convex parts formed by the long and short composite spun yarn and the concave parts formed by the yarns other than the long and short composite spun yarn becomes larger, making it possible to improve point contact.

[0026] Figure 2 is a schematic plan view showing the knit structure of a garment fabric according to one embodiment of the present invention. In this garment fabric 1, the front surface is arranged with knit stitches of long and short composite spun yarn 2, and the back surface is arranged with knit stitches of synthetic fiber multifilament yarn 3. Such a knit structure can be formed by double knit, smooth knit (double-sided knit), double-structure knit, etc.

[0027] Figure 3A is a schematic side view of a long-short composite spun yarn 2 of one embodiment used in the present invention, and Figure 3B is a schematic cross-sectional view thereof. This long-short composite spun yarn 2 is made by twisting a bundle of short fibers 5 and a filament yarn 6 in the same direction, and the bundle of short fibers 5 is a blend of moisture-absorbing and heat-generating short fibers 7 and polyester short fibers 8. This long-short composite spun yarn 2 can be manufactured, for example, by a spinning and twisting method using a ring spinning machine. [Examples]

[0028] The present invention will be further described using the following examples. However, the present invention is not limited to the following examples. The evaluation method is as follows: <Mass per unit area (basis weight)> Measurements were taken in accordance with JIS L1096:2010 Method A. <thickness> The measurement was performed using a specimen thickness gauge FS-60N (manufactured by Polymer Instruments Co., Ltd.) under a load of 60g. <Water absorption> The water absorption time was measured in accordance with JIS L 1907:2010 Method A (dropping method). <Moisture-absorbing heat generation temperature> The dried fabric was left in a humid environment, and the temperature changes were measured using thermography. <Heat retention> The heat retention performance was measured using the KES-F7 ThermoLab II. Measurements were taken under the following conditions: wind speed of 30 cm / sec, hot plate temperature of 40°C, ambient temperature of 20°C, and ambient relative humidity of 65% RH. <Heat dissipation when wet> As shown in Figure 4, a certain amount of water was dripped onto the back of the fabric, and the fabric was placed so that the back side was in contact with the heating plate of the KES-F7 Thermolab II. The integrated value of the power consumption (W) during a certain period of time was then measured. <Difference in height between concave and convex parts> The height of the uneven structure within the measurement range was confirmed using a one-shot 3D shape measuring machine (manufactured by Keyence Corporation). Multiple measurements were taken of the uneven areas, and the average value was calculated. The measurement range was 18 mm vertically and 24 mm horizontally. <Stretchability> Stretchability was measured in accordance with JIS L 1096:2010 Method A, using a benchtop precision universal testing machine (AUTOGRAPH AGS-X 5kN, manufactured by Shimadzu Corporation), with a maximum load of 1.8 kg and a tensile speed of 200 mm / min. The sample fabric size was 25 mm wide, 150 mm long, and a gripping distance of 100 mm. Elongation was calculated from the displacement at the maximum load. The elongation recovery rate was calculated by subtracting the sum of test forces from the sum of test forces up to the maximum load until the displacement reached zero. <Tensile strength, elongation> Measurements were taken in accordance with JIS L1095:2010, General Test Methods for Spun Yarns. The test was performed using a constant-speed elongation autograph with a tensile speed of 25 cm / min and a gripping distance of 25 cm. Tensile strength was calculated from the maximum point load, and elongation was calculated from the maximum point elongation.

[0029] (Example 1) <Thread usage> The following yarn was used. (Knitting yarn 1) Polyester (PET) multifilament false twist yarn, total fineness 84 decitex, number of filaments 72 (Knitting yarn 2) Polyester (PET) multifilament false twist yarn, total fineness 56 decitex, 72 filaments. (Knitting Yarn 3) A spun blended yarn using a ring spinning machine was used as a long-short composite yarn. The long fiber yarn was a water-repellent treated polyester (PET) multifilament false twist yarn (total fineness 33 decimeters, number of filaments 36), and the short fiber yarn was a blend of highly crosslinked acrylic short fibers with a fineness of 2.3 decimeters and a fiber length of 35 mm and polyester (PET) short fibers with a fineness of 1.3 decimeters and a fiber length of 3.5 mm (cotton count 40 single yarn, fineness 148 decimeters, twist count 669.3 turns / m, twist coefficient K=2.7). The mass percentage of each fiber in the long-short composite yarn was 25% by mass of PET multifilament false twist yarn, 32% by mass of highly crosslinked acrylic short fibers, and 43% by mass of PET short fibers. The tensile strength of this long-short composite yarn was 321 cN and the elongation was 14.4%. A side view is shown in Figure 10. The water-repellent treatment for the false twist yarn of knitting yarn 3 was performed as follows. (1) Drugs used As a water repellent, a 100-fold diluted solution of a non-fluorine water repellent (ON Water Repellent NF, manufactured by OG Nagase Color Chemical Co., Ltd.) with alkyl urethane as the main component was prepared, and the fiber surface was immersed in the solution to achieve a 4% owf (on the weight of fiber) concentration to apply the water repellent. After applying the water repellent, it was dried at 110°C for 1 minute. (2) Processing conditions Using the aforementioned chemical, the false-twist yarn strands were wound into a cheese shape, immersed in a water-repellent agent, and then cross-linked by dry curing to treat only the false-twist yarn with a water-repellent agent. Subsequently, the roving, consisting of highly cross-linked acrylic staple fibers and polyester (PET) staple fibers, was spun and twisted using a ring spinning machine to produce a long-short composite spun yarn. <Knitted fabric> A double circular knitted fabric was produced using a circular knitting machine with a gauge count of 22 per inch. The knitting yarns 1 and 2 were used as sinker loops, and the knitting yarn 3 was used as a needle loop. The PET multifilament yarn was arranged so that there was a larger proportion of it in the purl loops on one side, and the long and short composite spun yarn was arranged so that there was a larger proportion of it in the knit loops on the other side. The stitch structure was as shown in Figure 2. When the knitted fabric was considered to be 100% by mass, the proportions of each yarn were as follows: knitting yarn 1 (PET multifilament yarn) 47.0% by mass, knitting yarn 2 (PET multifilament yarn) 20.0% by mass, and knitting yarn 3 (long and short composite spun yarn) 33.0% by mass. This knitted fabric was treated to make it hydrophilic under the following conditions. (1) Drugs used As the hydrophilic polyester resin, we used product number KMZ-902 manufactured by Takamatsu Oil & Fat Co., Ltd., at 5% owf (abbreviation for on the weight of fiber). (2) Processing conditions The knitted fabric was immersed in an aqueous solution containing the aforementioned chemical and 5% owf of disperse dye, heated from room temperature to 130°C at a rate of 2°C / min, treated at 130°C for 60 minutes, cooled, washed with water, dried, and then heat-set to widen the fabric. This heat treatment caused the false twist yarns of knitting yarns 1-3 to shrink, imparting stretchability to the knitted fabric and simultaneously creating an uneven surface on the surface where the long and short composite spun yarns were arranged. The properties of the resulting knitted fabric are shown in Table 1. This knitted fabric was used to sew a shirt and pants, which are innerwear garments. The shirt and pants were sewn with the side containing more of the aforementioned long and short composite spun yarn facing the skin. The shirt and pants were found to have moisture-absorbing and heat-generating properties, while reducing the contact area between the sweat-soaked part and the skin when perspiration occurs. They were also found to be lightweight, bulky, and highly stretchable, making them suitable as sportswear for autumn and winter.

[0030] (Example 2) <Thread usage> The following yarn was used. (Knitting yarn 1) Hydrophilic treated polyester (PET) multifilament yarn, total fineness 56 decitex, number of filaments 36. The hydrophilic treatment was the same as in Example 1. (Knitting yarn 2) Knitting yarn 3 from Example 1 was used. <Knitting> A double circular knitted fabric was produced using a circular knitting machine with a gauge count of 24 per inch. The knitting yarn 1 was used as the sinker loop and the knitting yarn 3 as the needle loop. The PET multifilament yarn was arranged so that there was a larger proportion of it in the purl loops on one side, and the long and short composite spun yarn was arranged so that there was a larger proportion of it in the knit loops on the other side. The stitch structure was as shown in Figure 2. When the knitted fabric was considered to be 100% by mass, the proportion of each yarn was 66.1% by mass for knitting yarn 1 (PET multifilament yarn) and 33.9% by mass for knitting yarn 2 (long and short composite spun yarn). This knitted fabric was treated to make it hydrophilic under the same conditions as in Example 1. The properties of the resulting knitted fabric are shown in Table 1. Using this knitted fabric, a long-sleeved shirt and pants, which are outerwear or mid-layer garments, were sewn. The long-sleeved shirt and pants were sewn with the side containing more of the long and short composite yarn facing the skin, creating an uneven surface with raised areas formed by the long and short composite yarn. Furthermore, it was confirmed that the knitted fabric possessed moisture-absorbing and heat-generating properties, while reducing the contact area between the sweat-soaked area and the skin when perspiration occurs, and was lightweight, bulky, and highly stretchable, making it suitable as sportswear for autumn and winter.

[0031] (Comparative Example 1) The procedure was carried out in the same manner as in Example 1, except that the following were used: knitting yarn 1 was a hydrophilic treated polyester (PET) multifilament yarn with a total fineness of 84 decitex and 72 filaments (43.3% by mass); knitting yarn 2 was a hydrophilic treated polyester (PET) multifilament yarn with a total fineness of 84 decitex and 72 filaments (20.8% by mass); and knitting yarn 3 was a blended yarn of highly crosslinked acrylic staple fibers and polyester (PET) staple fibers (cotton count 40 single yarn, fineness 148 decitex, twist count 838.6 times / m, twist coefficient K=3.4) (35.9% by mass). The tensile strength of this staple fiber blended yarn was 308 cN and the elongation was 10.2%. A side view is shown in Figure 11.

[0032] (Comparative Example 2) The procedure was carried out in the same manner as in Example 1, except that the knitting yarn 1 was a hydrophilic treated polyester (PET) multifilament yarn with a total fineness of 84 decitex and 72 filaments (73% by mass), and the knitting yarn 2 was a blended yarn of highly crosslinked acrylic staple fibers and polyester (PET) staple fibers (cotton count 40 single yarn, fineness 148 decitex) (27% by mass).

[0033] (Comparative Example 3) The procedure was carried out in the same manner as in Example 1, except that hydrophilic treated polyester (PET) multifilament yarn, with a total fineness of 84 decitex and 72 filaments (100% by mass) was used as the knitting yarn 1. The results are shown in Table 1.

[0034] [Table 1]

[0035] As is clear from the results above, the fabrics of Examples 1 and 2 had low heat dissipation when wet. This means that less energy was needed to evaporate water from the fabric, and clothing sewn with this fabric actually exhibited good breathability even when sweating during exercise, preventing chills from sweat and making it comfortable for sports in cold weather. In contrast, the fabrics of Comparative Examples 1-3 had high heat dissipation properties when wet. When clothing was sewn with these fabrics, the fabric stuck to the skin when sweating during exercise, causing a chill from the sweat and making it uncomfortable. [Industrial applicability]

[0036] The fabric of the present invention is suitable not only for innerwear such as sports shirts, T-shirts, undershirts, briefs, tights, and general shirts and briefs, but also for middlewear, outerwear, socks, gloves, mufflers, hats, bandanas, scarves, neck warmers, and the like.
