Description

Highly breathable fabrics and textile products

[0001] The present invention relates to a woven fabric that is excellent not only in breathability but also in stretchability, UV protection, and stickiness prevention, and to a textile product made using the woven fabric.

[0002] In recent years, woven fabrics with excellent breathability have been proposed to improve comfort (see, for example, Patent Documents 1 to 3). However, these woven fabrics have yarn-free portions in both the warp and weft, and although they have excellent breathability, they are not satisfactory in terms of UV blocking properties.

[0003] On the other hand, in the field of sportswear, stretchability and anti-stickiness are also important properties, and fabrics with excellent stretchability and anti-stickiness are required.

[0005] The present invention has been made in view of the above background, and an object of the present invention is to provide a woven fabric that is excellent not only in breathability but also in stretchability, UV protection, and anti-stickiness, and a textile product made using the woven fabric.

[0006] The present inventors have conducted extensive research to solve the above problems and have completed the present invention. Thus, the present invention provides the following: 1. An air permeability of 30 cc / sec / cm ２ The highly breathable fabric described above contains elastic fibers, has a cover factor CF of 1000 to 4000, and has yarn-free portions in only one of the warp and weft yarns, where the cover factor CF is defined by the following formula: CF = (DWp / 1.1). １／２ ×MWp+(DWf / 1.1) １／２×MWf [DWp is the total warp fineness (dtex), MWp is the warp weave density (counts / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (counts / 2.54 cm).] 2. The highly breathable woven fabric according to item 1 above, wherein the stretchable fiber is a polyurethane fiber, a bicomponent fiber in which two components are bonded in a side-by-side or eccentric core-sheath configuration, or a polytrimethylene terephthalate fiber. 3. The highly breathable woven fabric according to item 1 or 2 above, wherein the yarn-free portions are formed by dissolving the yarn or by leaving hollow fibers during weaving. 4.

The highly breathable woven fabric according to any one of items 1 to 4 above, wherein the ultraviolet ray shielding rate is 85% or more, where the ultraviolet ray shielding rate is measured according to JIS L1925. 6. A highly breathable woven fabric according to any one of 1 to 5 above, having an ultraviolet protection factor of 30 or more, where the ultraviolet protection factor is measured according to AS / NZS 4399:1996. 7. A highly breathable woven fabric according to any one of 1 to 6 above, where the elastic fibers and fibers other than the elastic fibers are arranged alternately in at least one of the warp and weft. 8. A highly breathable woven fabric according to any one of 1 to 7 above, having a wet friction force of 100 g or less. 9. A highly breathable woven fabric according to any one of 1 to 8 above, having a tear strength of 8 N or more, where the tear strength is measured according to JIS L1096-2010 8.17 D method. 10. A highly breathable woven fabric according to any one of 1 to 9 above, having a slippage resistance of 3 mm or less. However, the slippage resistance is measured according to JIS L1096-2010 8.23 ​​Method B (load 117.7 N). 11. A textile product selected from the group consisting of sportswear, outdoor wear, men's clothing, women's clothing, workwear, protective clothing, footwear, and bags, which is made using the woven fabric described in any one of 1 to 10 above.

[0007] According to the present invention, a woven fabric having excellent breathability, stretchability, UV protection, and stickiness prevention properties, and a textile product using the woven fabric can be obtained.

[0008] In the woven fabric of the present invention, the air permeability is 30 cc / sec / cm ２or more (preferably 50 to 300 cc / sec / cm ２ It is important that the air permeability is 30 cc / sec / cm. ２ If the air permeability is smaller than this, comfort may decrease, which is not preferable. The air permeability is measured by JIS L1096-2010 8.26.1 Method A (Fragile method).

[0009] The woven fabric of the present invention contains elastic fibers. The inclusion of elastic fibers in the woven fabric not only imparts stretchability to the woven fabric but also improves seam slippage resistance. Furthermore, when elastic fibers and fibers other than elastic fibers (hereinafter sometimes referred to as "non-elastic fibers"), such as polyethylene terephthalate fibers (non-crimped yarns or false-twisted crimped yarns), are used and the two fibers are arranged alternately in at least one of the warp and weft (preferably 1-12:1-12 alternating, and particularly preferably 4-10:4-10 alternating), the difference in elasticity between the two fibers forms irregularities on the surface of the woven fabric, improving stickiness resistance, which is preferred.

[0010] In this case, preferred examples of the stretchable fiber include fibers composed of one component made of polytrimethylene terephthalate, composite fibers (conjugate filament yarns) in which two components are joined in a side-by-side or eccentric core-sheath configuration, elastic fibers (polyurethane-based fibers, polyetherester-based fibers, water-absorbent elastomer fibers, etc.), and unstretched polyester fibers.

[0011] Here, the composite fiber is preferably a composite fiber in which at least one component is made of polytrimethylene terephthalate, polybutylene terephthalate, or polyethylene terephthalate. Specific examples of two components include polytrimethylene terephthalate and polytrimethylene terephthalate, polytrimethylene terephthalate and polyethylene terephthalate, polyethylene terephthalate and polyethylene terephthalate, and polyethylene terephthalate and polybutylene terephthalate.

[0012] Here, polytrimethylene terephthalate refers to a fiber made of polyester containing trimethylene terephthalate units as the main repeating units, and refers to fibers containing trimethylene terephthalate units in an amount of 50 mol% or more, preferably 70 mol% or more, more preferably 80 mol% or more, and particularly preferably 90 mol% or more. Therefore, the polytrimethylene terephthalate fiber contains other acid components and / or glycol components as third components in a total amount of 50 mol% or less, preferably 30 mol% or less, more preferably 20 mol% or less, and particularly preferably 10 mol% or less.

[0013] Polytrimethylene terephthalate is produced by condensing terephthalic acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof in the presence of a catalyst under suitable reaction conditions.

[0014] Examples of the third component to be added include aliphatic dicarboxylic acids (such as oxalic acid and adipic acid), alicyclic dicarboxylic acids (such as cyclohexanedicarboxylic acid), aromatic dicarboxylic acids (such as isophthalic acid and sodium sulfoisophthalic acid), aliphatic glycols (such as ethylene glycol, 1,2-trimethylene glycol, and tetramethylene glycol), alicyclic glycols (such as cyclohexane glycol), aromatic dioxy compounds (such as hydroquinone bisphenol A), aromatic-containing aliphatic glycols (such as 1,4-bis(β-hydroxyethoxy)benzene), and aliphatic oxycarboxylic acids (such as p-oxybenzoic acid). The polyethylene terephthalate may be a copolymer of three components. It may also be recycled or chemically recycled. Furthermore, it may be one obtained using a catalyst containing a specific phosphorus compound and a titanium compound, as described in JP-A Nos. 2004-270097 and 2004-211268.

[0015] The polytrimethylene terephthalate, polyethylene terephthalate, polybutylene terephthalate, etc. may contain one or more of a micropore-forming agent, a cationic dye dyeable agent, a coloration inhibitor, a heat stabilizer, a fluorescent whitening agent, a matting agent, a colorant, a moisture absorbent, and inorganic fine particles.

[0016] The composite fiber can be produced, for example, by the method described in JP-A-2009-46800.

[0017] The fibers (non-elastic fibers) other than the elastic fibers that make up the woven fabric are not particularly limited, but polyester non-crimped yarns and polyester false-twist crimped yarns made of polyester are preferred. Examples of such polyesters include polyesters that contain terephthalic acid as the main acid component and at least one glycol selected from the group consisting of alkylene glycols having 2 to 6 carbon atoms, i.e., ethylene glycol, tetramethylene glycol, pentamethylene glycol, and hexamethylene glycol, with ethylene glycol being particularly preferred.

[0018] Such polyesters may contain a small amount (usually 30 mol % or less) of a copolymerization component, if necessary. In this case, examples of the difunctional carboxylic acid other than terephthalic acid that can be used include aromatic, aliphatic, and alicyclic difunctional carboxylic acids such as isophthalic acid, naphthalene dicarboxylic acid, diphenyl dicarboxylic acid, diphenoxyethane dicarboxylic acid, β-hydroxyethoxybenzoic acid, p-oxybenzoic acid, 5-sodium sulfoisophthalic acid, adipic acid, sebacic acid, and 1,4-cyclohexane dicarboxylic acid. Examples of diol compounds other than the glycols include aliphatic, alicyclic, and aromatic diol compounds such as cyclohexane-1,4-dimethanol, neopentyl glycol, bisphenol A, and bisphenol S, as well as polyoxyalkylene glycols.

[0019] The polyester may be synthesized by any method. For example, in the case of polyethylene terephthalate, it may be produced by a first-stage reaction in which terephthalic acid and ethylene glycol are directly esterified, or a lower alkyl ester of terephthalic acid such as dimethyl terephthalate is transesterified with ethylene glycol, or terephthalic acid is reacted with ethylene oxide to produce a glycol ester of terephthalic acid and / or its oligomer, followed by a second-stage reaction in which the reaction product of the first stage is heated under reduced pressure to polycondensate until the desired degree of polymerization is achieved. Material- or chemically recycled polyesters may also be used. Furthermore, aliphatic polyesters such as polylactic acid and stereocomplex polylactic acid may also be used.

[0020] The polyester may optionally contain one or more of the following: a matting agent (titanium dioxide), a micropore-forming agent (organic metal sulfonate), a color inhibitor, a heat stabilizer, a flame retardant (antimony trioxide), a fluorescent brightener, a color pigment, an antistatic agent (metal sulfonate), a moisture absorbent (polyoxyalkylene glycol), an antibacterial agent, and other inorganic particles. In particular, if the polyester contains 0.2 wt % or more (more preferably 0.2 to 2.5 wt %) of the matting agent relative to the weight of the polyester, the woven fabric can be imparted with an ultraviolet ray shielding effect and transparency-proofing properties, which is preferred.

[0021] In the woven fabric of the present invention, the elastic fiber may be contained in the woven fabric as a single yarn, or may be contained in the woven fabric as a composite yarn (air-blended yarn, composite false twist textured yarn, doubled-twist yarn, etc.) with other yarns (for example, non-crimped yarn, etc.). Also, two or more types of yarns may be arranged in the warp and / or weft, and one of the yarns may be an elastic fiber, while the other yarns may be polyethylene terephthalate fiber (non-crimped yarn or false twist crimp textured yarn) or a fiber that dissolves in water or a solvent, as described below.

[0022] In this case, in order to obtain excellent breathability, stretchability, UV shielding properties, and stickiness prevention properties, the fibers constituting the woven fabric, such as the elastic fibers and non-elastic fibers, are preferably multifilaments having a total fineness of 20 to 220 dtex (more preferably 20 to 167 dtex), a number of filaments of 1 to 300 (more preferably 12 to 300), and a single fiber fineness of 0.00002 to 3.0 dtex (more preferably 0.1 to 2.0 dtex, particularly preferably 0.3 to 1.0 tex).

[0023] In addition, examples of the cross-sectional shape of the single fiber constituting the woven fabric include a round cross section, an oval cross section, a triangle, a square, a cross, a flat, a flat with a constriction, an H-shape, a W-shape, and the like.

[0024] In the woven fabric of the present invention, the absence of yarns in only one of the warp and weft yarns allows for both breathability and UV-blocking properties. The absence of yarns refers to streaky gaps caused by missing yarns. If the absence of yarns in both the warp and weft yarns is present, breathability will improve but UV-blocking properties may decrease, which is not preferred. Furthermore, if the absence of yarns in both the warp and weft yarns is present, breathability may decrease, which is also not preferred.

[0025] Here, the method for forming the yarn-free portions is preferably by dissolving the yarns or by leaving empty yarns during weaving.

[0026] As for dissolving the yarn, for example, fibers soluble in water or solvents as described in JP 2015-151630 A and JP 2021-116508 A (e.g., polyvinyl alcohol-based fibers, polyester-based fibers copolymerized with a third component such as 5-sodium sulfoisophthalic acid or methoxypolyoxyethylene glycol, polylactic acid-based fibers, commercially available products such as "Bell Pure" (trade name) manufactured by KB Seiren Co., Ltd., with a total fineness of about 20 to 220 dtex) are used, and the fibers soluble in water or solvents are preferably dissolved and removed after weaving by intermittently arranging only one of the warp and weft yarns. In this case, it is preferable that the yarn-free portion of the warp (weft) has a ratio of non-soluble fiber: soluble fiber = 3 to 30: 1 to 8, and non-soluble fiber: soluble fiber = 3 to 16: 1 to 6 is particularly preferred.

[0027] On the other hand, as described in JP 2021-116508 A, when empty feathers are used during weaving (fabric formation), it is advisable to either not pass the warp threads through the reed at regular intervals or to reduce the number of warp threads when passing them through the reed in the warp preparation process. In this case, it is preferable that the warp (weft) has a ratio of 3 to 30 threads in the presence section: 1 to 4 threads in the absence section, and it is particularly preferable that the ratio of 3 to 16 threads in the presence section: 1 to 2 threads in the absence section. Two threads are often passed between each reed vane through which the warp threads are passed. For example, if the ratio of empty feathers is 4 reed vanes: 1 reed vane, the ratio of existing threads: non-existent threads in the warp is 8 threads: 2 threads in the presence section: non-existent section. Furthermore, in the case of weft yarns, when weaving using a water jet loom or the like, it is advisable to beat them at regular intervals.

[0028] The woven fabric of the present invention can be woven using the above-mentioned yarns on a conventional loom. There are no limitations on the weave of the woven fabric, and preferred examples include plain weave and twill weave.

[0029] In this case, when forming yarn-free portions by dissolving yarns, it is preferable to use stretchable fibers that are insoluble in alkali (or water), non-stretchable fibers that are insoluble in alkali (or water), and non-stretchable fibers that are soluble in alkali (or water), to arrange the non-soluble fibers and soluble fibers in the above-mentioned ratio only in either the warp or weft, and to arrange the stretchable fibers and non-stretchable fibers alternately in the above-mentioned ratio in at least one of the warp and weft.

[0030] Furthermore, when forming yarn-free portions by empty filaments or blank beating during weaving, it is preferable to use stretchable fibers that are not soluble in alkali (or water) and non-stretchable fibers that are not soluble in alkali (or water), alternately arrange them in the above-mentioned ratio in at least one of the warp and weft, and weave the fabric by empty filaments or blank beating.

[0031] Next, if a fiber that dissolves in alkali (or water) is used, the fiber is dissolved. For example, if the dissolvable fiber is a water-soluble fiber such as a polyvinyl alcohol-based fiber, the fabric can be immersed in water. The water temperature is preferably 20°C or higher, and it is more preferable to dissolve and remove the fiber in a bath at 50°C to 100°C. If the dissolvable fiber is an alkali-soluble fiber, the fabric can be immersed in a bath of an alkaline aqueous solution containing sodium hydroxide. The bath temperature is preferably 90 to 100°C, and the time is preferably 10 to 30 minutes. The sodium hydroxide concentration is preferably 0.5 to 3% ows, and the bath ratio is preferably 1:30 to 1:50.

[0032] Furthermore, post-processing such as ordinary dyeing, raising, calendaring, embossing, heat storage, water absorption (sweat absorption), water repellency, antistatic, and antibacterial may be carried out as appropriate.

[0033] As such a water-absorbing treatment, it is preferable to apply a hydrophilizing agent such as PEG diacrylate and its derivatives, or polyethylene terephthalate-polyethylene glycol copolymer in an amount of 0.25 to 0.50% by weight based on the weight of the fabric by a same-bath process during dyeing.

[0034] Furthermore, the type of water repellent agent used in the water repellent treatment is not particularly limited. Examples include fluorine-based compounds, hydrocarbon-based compounds, and silicone-based compounds. If necessary, an antistatic agent, melamine resin, and catalyst are mixed to form a water repellent agent having a concentration of approximately 3 to 15% by weight, and the surface of the woven fabric is preferably treated with this agent at a pickup rate of approximately 50 to 90%. Examples of methods for treating the surface of the woven fabric with the agent include padding and spraying. Among these, the padding method is preferred for penetrating the agent deep into the woven fabric. The pickup rate is the weight ratio (%) of the agent to the weight of the woven fabric (before application of the agent).

[0035] Furthermore, the antistatic agent is preferably a polyester resin containing a polyethylene glycol group, a urethane resin containing a polyethylene glycol group, a reaction product of a polycationic compound containing a polyethylene glycol group with a diglycidyl ether, etc. Antistatic compounds such as anionic surfactants such as higher alcohol sulfates, sulfated oils, sulfonates, and phosphates, cationic surfactants such as amine salts, quaternary ammonium salts, and imidaline quaternary salts, nonionic surfactants such as polyethylene glycols and polyhydric alcohol esters, and amphoteric surfactants such as imidaline quaternary salts, alanine types, and betaine types may also be used.

[0036] In order to obtain excellent breathability, stretchability, UV protection, and stickiness prevention properties from the thus obtained woven fabric, it is important that the cover factor CF of the woven fabric is in the range of 1000 to 4000. The cover factor CF is defined by the following formula: CF = (DWp / 1.1) １／２ ×MWp+(DWf / 1.1) １／２ × MWf (DWp is the total warp fineness (dtex), MWp is the warp weave density (counts / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (counts / 2.54 cm).) The basis weight of the woven fabric was 300 g / m ２ or less (more preferably 50 to 300 g / m ２ ) It is preferable that the basis weight is 300 g / m ２ If it is larger than this, the weight of the fabric will be large, and the comfort of wearing the fabric may be impaired.

[0037] The woven fabric thus obtained has high breathability due to the yarn-free areas, like a bamboo blind. At the same time, the elastic fibers provide stretchability. Furthermore, the difference in shrinkage between the elastic and non-elastic fibers creates unevenness on the surface of the woven fabric, providing excellent stickiness prevention. Furthermore, because the yarn-free areas are present only on one side of the warp or weft, it becomes easier to achieve the conflicting properties of breathability and UV protection.

[0038] Here, it is preferable that the elongation in the warp direction or weft direction is 10% or more (more preferably 15 to 40%). It is also preferable that the UV shielding rate is 85% or more. However, the UV shielding rate is measured in accordance with JIS L1925. It is also preferable that the UV protection factor is 30 or more (more preferably 30 to 80). However, the UV protection factor is measured in accordance with AS / NZS 4399:1996. It is also preferable that the wet friction force is 100 g or less (more preferably 50 to 100 g). It is also preferable that the tear strength is 8 N or more (more preferably 8 to 20 N). However, the tear strength is measured in accordance with JIS L1096-2010 8.17 Method D. It is also preferable that the slip resistance is 3 mm or less (more preferably 0.1 to 2 mm). However, the slip resistance is measured in accordance with JIS L1096-2010 8.23 ​​Method B (load 117.7 N).

[0039] The woven fabric is suitably used as textile products such as sportswear, outdoor wear, men's clothing, women's clothing, workwear, protective clothing, footwear, bags, and the like.

[0040] Examples and comparative examples of the present invention will be described in detail below, but the present invention is not limited to these. The measurement items in the examples were measured by the following methods. (1) Cover Factor The cover factor CF of the woven fabric was calculated using the following formula: CF = (DWp / 1.1) １／２ ×MWp+(DWf / 1.1) １／２ × MWf where DWp is the total warp fineness (dtex), MWp is the warp weave density (counts / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (counts / 2.54 cm). (2) Basis Weight of Woven Fabric Basis weight (g / m ２ (3) Air permeability: The air permeability (cc / sec / cm) was measured according to JIS L1096-2010 8.26.1 A method (Fragile air permeability tester method). ２) was measured. Five samples were used, and the average was calculated. (4) Elongation of the fabric: The elongation (%) of the fabric was measured according to JIS L1096-2010 8.16 B method. (5) UV shielding rate: The UV shielding rate (%) was measured according to JIS L1925. (6) UV protection factor: The UV protection factor was measured according to AS / NZS 4399:1996. (7) Wet friction: The wet friction force (g) of the backside of the fabric was measured according to the following measurement method. As shown in Figure 1 of JP-A-9-195172, a fabric (sample) to be measured, 15 cm long and 6 cm wide, was placed on a metal roller with a polished surface and a straight diameter of 8 cm, one end of which was attached to a stress-strain gauge (U-gauge), and a 10 g clip was attached to the lower end to tension the fabric. Next, while rotating the metal roller in the direction opposite to the U-gauge at a surface speed of 7 cm / sec, exactly 1 cc of water was gently injected between the metal roller and the fabric using a syringe. At this time, the tension applied to the fabric was measured via the U-gauge and recorded on a recorder, and the maximum value was defined as the wet friction force. (8) Tear Strength: Tear strength (N) was measured according to JIS L1096-2010 8.17 Method D. (9) Slip Resistance: Slip resistance (mm) was measured according to JIS L1096-2010 8.23 ​​Method B (load 117.7 N).

[0041] [Example 1] A plain weave fabric with a warp density of 99 threads / 2.54 cm and a weft density of 63 threads / 2.54 cm was woven using semi-dull polyethylene terephthalate multifilament false twisted crimped yarn (total fineness 84 dtex / 72 threads, non-elastic fiber) and an easily alkali-soluble polyester fiber (total fineness 110 dtex / 72 threads, non-elastic fiber) arranged alternately in a ratio of 5 threads:1 as the warp yarn, and semi-dull polyethylene terephthalate multifilament false twisted crimped yarn (total fineness 167 dtex / 72 threads, non-elastic fiber) and a conjugate filament yarn of polyethylene terephthalate and polytrimethylene terephthalate (total fineness 167 dtex / 72 threads, elastic fiber) arranged alternately in a ratio of 1 thread:1 as the weft yarn. Next, the easily alkali-soluble polyester fibers were dissolved in a scouring step, and the woven fabric was subjected to ordinary dyeing and finishing and water absorption treatment, followed by final setting.

[0042] In the woven fabric thus obtained, there are no-yarn portions only in the warp yarns, and the basis weight is 125 g / m ２ , warp density 133 / 2.54cm, weft density 70 / 2.54cm, cover factor 2009, breathability 60cc / sec / cm ２ The weft elongation was 23%, the UV shielding rate was 94%, the UV protection factor was 30, the wet friction force was 75 g, the tear strength was 11 N, and the slip resistance was 1.0 mm. This woven fabric was excellent not only in breathability and stretchability but also in UV shielding properties.

[0043] [Example 2] As the warp yarns, semi-dull polyethylene terephthalate multifilament false twist crimped yarn (total fineness 84 dtex / 72 threads, non-elastic fiber), polyethylene terephthalate and polytrimethylene terephthalate conjugate filament yarn (total fineness 84 dtex / 36 threads, elastic fiber), and easily alkali-soluble polyester fiber (total fineness 110 dtex / 72 threads) were alternately arranged in this order in a ratio of 6:6:4. As the weft yarn, full-dull polyethylene terephthalate multifilament false twist crimped yarn (total fineness 84 dtex / 72 threads, non-elastic fiber) and polyethylene terephthalate and polytrimethylene terephthalate conjugate filament yarn (total fineness 84 dtex / 36 threads, elastic fiber) were arranged alternately in a 1:1 ratio, and a plain weave fabric was woven with a warp density of 87 threads / 2.54 cm and a weft density of 89 threads / 2.54 cm.

[0044] Next, the easily alkali-soluble polyester fibers were dissolved in a scouring step, and the woven fabric was subjected to ordinary dyeing and finishing and water absorption treatment, followed by final setting.

[0045] In the woven fabric thus obtained, there are no-yarn portions only in the warp yarns, and the basis weight is 123 g / m ２ , warp density 131 threads / 2.54cm, weft density 111 threads / 2.54cm, cover factor 2095, breathability 55cc / sec / cm ２The weft elongation was 25%, the UV shielding rate was 97%, the UV protection coefficient was 50+, the wet friction force was 60 g, the tear strength was 11 N, and the slippage resistance was 1.1 mm. Furthermore, unevenness occurred on the surface of the woven fabric due to the difference in shrinkage between the elastic fiber and the non-elastic fiber. This woven fabric was excellent not only in breathability and stretchability, but also in UV shielding and anti-stickiness.

[0046] Example 3: Semi-dull polyethylene terephthalate multifilament false-twisted crimped yarn (total fineness 84 dtex / 72 threads, non-elastic fiber) was used as the warp yarn. Two warp yarns were passed per reed fin, with a ratio of 4 reed fins to 1 reed fin, forming an open fin. Semi-dull polyethylene terephthalate multifilament false-twisted crimped yarn (total fineness 167 dtex / 72 threads, non-elastic fiber) and polyethylene terephthalate / polytrimethylene terephthalate conjugate filament yarn (total fineness 167 dtex / 72 threads, elastic fiber) were alternately arranged in a 1:1 ratio to weft, and a plain weave fabric was woven with a warp density of 105 threads / 2.54 cm and a weft density of 65 threads / 2.54 cm. The fabric was then subjected to conventional dyeing and finishing processes and a water-absorbency treatment, followed by a final set.

[0047] The fabric thus obtained had a basis weight of 130 g / m ２ , warp density 135 / 2.54cm, weft density 72 / 2.54cm, cover factor 2051, breathability 55cc / sec / cm ２ The elongation in the weft direction was 20%, the UV shielding rate was 93%, the UV protection factor was 30, the wet friction force was 70 g, the tear strength was 12 N, and the slip resistance was 1.2 mm. This woven fabric was excellent not only in breathability and stretchability but also in UV shielding properties.

[0048] Comparative Example 1: A plain weave fabric was woven with a warp density of 99 threads / 2.54 cm and a weft density of 63 threads / 2.54 cm, using semi-dull polyethylene terephthalate multifilament false-twisted crimped yarn (total fineness 84 dtex / 72 filaments, non-elastic fiber) as the warp yarn and a semi-dull polyethylene terephthalate multifilament false-twisted crimped yarn (total fineness 167 dtex / 72 filaments, non-elastic fiber) and a polyethylene terephthalate / polytrimethylene terephthalate conjugate filament yarn (total fineness 167 dtex / 72 filaments, elastic fiber) as the weft yarn, alternating in a 1:1 ratio. The fabric was then subjected to conventional dyeing and finishing processes and a water-absorbency treatment, followed by a final set.

[0049] In the woven fabric thus obtained, there were no yarn-free portions in either the warp or weft, and the fabric weight was 130 g / m ２ , warp density 140 / 2.54cm, weft density 72 / 2.54cm, cover factor 2094, breathability 20cc / sec / cm ２ The weft elongation was 23%, the UV shielding rate was 95%, the UV protection coefficient was 30, the wet friction force was 80 g, the tear strength was 11 N, and the slip resistance was 1.0 mm, and the fabric had poor breathability.

[0050] [Comparative Example 2] A plain weave fabric was woven with a warp density of 99 threads / 2.54 cm and a weft density of 63 threads / 2.54 cm using semi-dull polyethylene terephthalate multifilament false twist crimped yarn (total fineness 84 dtex / 72 threads, non-elastic fiber) as the warp yarn and a polyethylene terephthalate / polytrimethylene terephthalate conjugate filament yarn (total fineness 167 dtex / 72 threads, elastic fiber) as the weft yarn. The fabric was then subjected to a conventional dyeing and finishing process and a water absorption process, followed by a final setting.

[0051] In the woven fabric thus obtained, there were no yarn-free portions in either the warp or weft, and the fabric weight was 130 g / m ２ , warp density 140 / 2.54cm, weft density 72 / 2.54cm, cover factor 2094, breathability 20cc / sec / cm ２The weft elongation was 23%, the UV shielding rate was 95%, the UV protection coefficient was 30, the wet friction force was 120 g, the tear strength was 11 N, and the slip resistance was 1.0 mm, and the fabric was poor in breathability and anti-stickiness.

[0052] Comparative Example 3 The same procedure as in Example 1 was repeated, except that a semi-dull polyethylene terephthalate multifilament false twist crimped yarn (total fineness 84 dtex / 72 threads, non-stretchable fiber) and an easily alkali-soluble polyester fiber (total fineness 110 dtex / 72 threads, non-stretchable fiber) were alternately arranged in this order at a ratio of 5 threads:1 as the warp yarn, and an easily alkali-soluble polyester fiber (total fineness 110 dtex / 72 threads, non-stretchable fiber) and a conjugate filament yarn of polyethylene terephthalate and polytrimethylene terephthalate (total fineness 167 dtex / 72 threads, stretchable fiber) were alternately arranged in this order at a ratio of 1 thread:5 as the weft yarn.

[0053] The fabric thus obtained had yarn-free portions in both the warp and weft, and compared with the fabric obtained in Example 1, the breathability was good but the ultraviolet shielding rate was poor.

[0054] According to the present invention, a woven fabric having excellent breathability, stretchability, UV protection, and stickiness prevention properties, as well as a textile product using the woven fabric, are provided, and are of great industrial value.
