Summary of the Invention

Problems to be Solved by the Invention

[0004] Regarding clothing to be worn during exercise in seasons with low outside air temperatures such as spring, autumn, and winter, it is required to have heat retention properties because it feels cold at the beginning of exercise, and after a certain period of exercise, sweating occurs, so water absorption and quick-drying properties and sweat treatment properties are required. Immediately after exercise, it is required to suppress cold sweating caused by sweat staying on the skin surface. However, in the case of the knitted fabric having the loop pile yarn described in Patent Document 1, although it has heat retention property at the beginning of exercise, the knitted fabric becomes wet with sweating after the middle stage of exercise. In the wet state, it cannot maintain breathability, and there is a problem that the ability to process sweat on the skin surface decreases. Further, as a result of the decrease in sweat disposability, there is a problem that sweat tends to stay on the skin surface even immediately after exercise, resulting in sweat chill and the like. In the case of the knitted fabric having through holes described in Patent Document 2, there is a problem that coldness is felt at the beginning of exercise. Further, it has excellent sweat disposability that can maintain breathability even in a wet state, and by constantly vaporizing the sweat on the skin, it is possible to suppress the amount of sweat staying on the skin surface immediately after exercise. However, there is a problem that coldness due to sweat is felt when the wet knitted fabric comes into contact with the skin, and coldness is felt even immediately after exercise.

[0005] In order to solve the above-mentioned conventional problems, the present invention provides a knitted fabric for clothing that is excellent in water absorption and quick drying properties, breathability when wet, and heat retention property, and can suppress sweat chill, and a clothing including the same.

Embodiments for Carrying Out the Invention

[0010] In order to solve the above-described problems, the inventors of the present invention have conducted extensive studies. As a result, they have found that: (1) providing through-holes penetrating in the thickness direction in the knitted fabric; (2) using in combination at least one fiber yarn (I) selected from the group consisting of hydrophobic fiber yarns and water-repellent fiber yarns and hydrophilic fiber yarns (II), and arranging the fiber yarn (I) in at least a part of the region in contact with the through-holes; (3) providing an uneven structure on the back surface of the knitted fabric, setting the height of the needle loops constituting the convex portions to 0.8 mm or more, and setting the height of the needle loops adjacent to the through-holes in the vertical or horizontal direction to 0.8 to 2.0 mm, thereby achieving excellent water absorption and quick drying properties, air permeability when wet, and heat retention properties, and being able to suppress cold sweats. In this specification, "needle loop" means the upwardly curved portion of the knitting in the knitted fabric. In this specification, the back surface means the surface on the body side, and the front surface means the surface on the side opposite to the body side.

[0011] In spring, autumn, and winter sports scenes, the outside air temperature is low, and the heat of the body easily moves to the outside air side. In order to exercise comfortably, it is often necessary to wear clothing with excellent heat retention properties. However, the inventors of the present invention have focused on the fact that the functional requirements for comfortable exercise are different in the actual phases of exercise. Specifically, in the initial stage of exercise, the body temperature is at a normal level and the body does not need to dissipate heat. Therefore, heat retention is important for comfortable exercise. Since the knitted fabric for clothing of the present invention has an uneven structure (hereinafter also simply referred to as an uneven structure) with a height of the convex portions (needle loops) on the back surface of 0.8 mm or more, it is easy to retain an air layer between the knitted fabric and the body, and higher heat retention can be achieved compared to a knitted fabric of the same thickness without an uneven structure on the general back surface, and it is possible to provide a comfortable warmth in the initial stage of exercise. Compared with a knitted fabric without an uneven structure on the back surface, a knitted fabric with an uneven structure on the back surface has less heat transfer from the body to the outside air and can achieve higher heat retention. During the middle stage of exercise, as the body temperature rises along with the increase in muscle temperature after exercising for a certain period of time, the body needs to dissipate heat and sweating occurs. Along with sweating, the knitted fabric absorbs sweat moisture and gets wet, changing the knitted fabric to a wet state. Also, when the body starts to sweat, it becomes necessary to dry the sweat on the skin, that is, to appropriately process the sweat. To process the sweat, in addition to water absorption and quick-drying properties, the breathability of the wet state is important for vaporizing the sweat on the skin even when the knitted fabric is wet. The knitted fabric for clothing of the present invention has through-holes penetrating in the thickness direction of the knitted fabric, and at least a part of the region in contact with the through-holes is arranged with one or more fiber yarns (I) selected from the group consisting of hydrophobic fiber yarns and water-repellent fiber yarns, and the height of the needle loops adjacent to the through-holes in the vertical direction or the horizontal direction of the through-holes is 0.8 to 2.0 mm, so that the breathability of the knitted fabric can be ensured even when the knitted fabric is in a wet state. By ensuring the breathability of the knitted fabric even in a wet state, the vaporization of the sweat on the skin can always be promoted, so it becomes easier to keep the skin dry. Also, by having an uneven structure on the back surface, the point contact property is improved, and even when the knitted fabric is in a wet state, the area of contact between the wet part of the knitted fabric and the skin is small, and it becomes difficult to feel stickiness or the wet feeling of the knitted fabric. By suppressing the discomfort caused by sweat while processing the sweat on the skin, it is possible to provide comfort during the middle stage of exercise. Furthermore, immediately after exercise, since the body temperature is also decreasing, it approaches a state where heat dissipation by sweat is unnecessary. Therefore, it becomes important to keep the heat retention property and the sweat moisture on the skin surface to a minimum. The knitted fabric for clothing of the present invention has an uneven structure on the back surface, so as described above, it is easy to hold an air layer between the knitted fabric and the body (skin), and thus it is possible to achieve higher heat retention property compared to a general knitted fabric of the same thickness. In addition, since the point contact property is improved, the area of contact between the wet part of the knitted fabric and the skin becomes small, and unnecessary heat dissipation by sweat can be suppressed, and sweating and getting cold can be suppressed. Also, since the sweat on the skin is always vaporized during the middle stage of exercise, it is possible to suppress the amount of sweat staying on the skin surface immediately after exercise, and further suppress unnecessary heat dissipation by sweat. Thus, the fabric for clothing of the present invention is excellent in water absorption and quick drying properties, breathability when wet, and heat retention properties, can suppress cold sweats, reduce the discomfort likely to occur in each scene such as the beginning, middle, and end of exercise in spring, autumn, and winter, and can provide comfort from the beginning to the end of exercise.

[0012] The fabric for clothing has through holes penetrating in the thickness direction of the fabric. At least a part of the region in contact with the through holes is arranged with one or more fiber yarns (I) selected from the group consisting of hydrophobic fiber yarns and water-repellent fiber yarns. Thereby, the surface tension due to the capillary action of the through holes becomes large, and it becomes difficult to form a water film near the through holes. Also, since liquid sweat is easily absorbed by the hydrophilic fiber (II), the moisture easily moves from the vicinity of the through holes to the portion where the hydrophilic fiber (II) is arranged. The fabric for clothing is excellent in water absorption and quick drying properties, and can easily maintain the voids of the through holes even in a wet state, and can maintain breathability even in a wet state such as when the fabric for clothing is wet with sweat, and can promote the sweat treatment during liquid-phase sweating.

[0013] When the fabric for clothing is suspended in a wet state so that the thickness direction is horizontal, it is preferable that the through holes maintain voids. From the viewpoint of easily maintaining the void shape in the wet state, the hydrophobic fiber yarn and / or the water-repellent fiber yarn (I) are preferably arranged around and in contact with the void portion of the through hole. Thereby, even when the fabric for clothing gets wet such as being wet with sweat, the through holes maintain voids (through state in the thickness direction), and the processability of liquid sweat (moisture) is further enhanced. In this specification, the physical properties in the wet state mean the physical properties measured in a state where 300 parts by weight of water is absorbed with respect to 100 parts by weight of the fabric for clothing. In this specification, unless otherwise specified, the physical properties of the fabric for clothing mean the physical properties measured in a dry state (left in a standard state of temperature: 20 ± 5°C, relative humidity: 65%).

[0014] The fiber yarn (I) can be any one such as a spun yarn, a multifilament yarn, a crimped yarn obtained by processing a multifilament yarn, etc. Examples of the hydrophobic fiber yarn include fiber yarns composed of hydrophobic fibers such as polypropylene fibers, polyethylene fibers, and polyester fibers. Examples of the water-repellent fiber yarn include water-repellent processed yarns obtained by subjecting organic fiber yarns to water-repellent processing. Examples of the organic fiber yarn include fiber yarns containing natural fibers and / or synthetic fibers. From the viewpoint of quick-drying property, water-repellent processed yarns obtained by subjecting fiber yarns containing hydrophobic fibers to water-repellent processing are preferred. Specifically, the fiber yarn (I) is preferably at least one selected from polypropylene fiber yarns, polyester (such as PET) water-repellent processed yarns, acrylic water-repellent processed yarns, nylon water-repellent processed yarns, acetate water-repellent processed yarns, and ethylene vinyl alcohol water-repellent processed yarns. The water-repellent processed yarn may be one that has been water-repellent processed in the state of a fiber or yarn, or may be one that has been water-repellent processed in the state of a knitted fabric.

[0015] The water-repellent processing is not particularly limited, but can be carried out as follows. For example, a method of winding a yarn into a cheese shape, dipping it in a water-repellent processing agent, and then subjecting it to a crosslinking reaction by dry curing; a method of repeatedly applying a water-repellent processing agent to a yarn on these machines using a false-twisting machine or a spinning machine equipped with a water-repellent processing agent application facility, and then subjecting it to a crosslinking reaction by dry curing; a method of providing a water-repellent processing agent application facility on a spinning and drawing machine at the raw yarn manufacturing stage, applying a water-repellent processing agent to a yarn on these machines, and then subjecting it to a crosslinking reaction by dry curing, etc.

[0016] As the water-repellent processing agent, those usually used as water-repellent agents for synthetic fibers such as silicone-based water-repellent agents and fluorine-based water-repellent agents may be used, and there is no particular limitation. Among them, from the viewpoint of durability, fluorine-based water-repellent agents are preferred. Also, from the viewpoint of durability, an aminoplast resin, a polyfunctional blocked isocyanate group-containing urethane resin, ethylene carbonate, etc. may be added to the water-repellent agent.

[0017] The hydrophilic fiber yarn (II) can be any type, such as a spun yarn, a multifilament yarn, a crimped yarn processed from a multifilament yarn, etc. By including hydrophilic fiber (II) in at least a part of the knitted fabric, it becomes easier to absorb the sweat discharged from the body surface. The hydrophilic fiber yarn is not particularly limited, but examples include cellulose fiber spun yarns such as cotton, rayon, acetate, and triacetate, nylon fiber yarns, blended yarns of these fibers and polyester fibers, composite spun yarns (including worsted twist yarns) of these fibers and polyester (such as PET) multifilament yarns, polyester hydrophilic processed yarns obtained by hydrophilizing polyester fiber yarns, acrylic hydrophilic processed yarns obtained by hydrophilizing acrylic fiber yarns, polyurethane hydrophilic processed yarns obtained by hydrophilizing polyurethane fiber yarns, etc. The hydrophilic processed yarn may be one using a hydrophilized resin, may be one hydrophilized in the state of a fiber or yarn, or may be one hydrophilized in the state of a knitted fabric. As the fiber yarn (II), one hydrophilic fiber yarn may be used alone, or two or more hydrophilic fiber yarns may be used in combination.

[0018] The hydrophilization treatment of the fiber yarn or knitted fabric is not particularly limited, but can be carried out as follows. For example, after hydrophilically processing the knitted fabric in the bath simultaneously with dyeing in the dyeing process, or after dyeing, immersing the knitted fabric in a bath containing a hydrophilic substance and then causing a crosslinking reaction by dry curing; a method of winding the yarn into a cheese shape, immersing it in a hydrophilic substance, and then causing a crosslinking reaction by dry curing; a method of repeatedly applying a hydrophilic substance to the yarn on these machines using a false twisting machine or a spinning machine equipped with a hydrophilic substance application facility and then causing a crosslinking reaction by dry curing; a method of providing a hydrophilic substance application facility on a spinning and drawing machine at the raw yarn manufacturing stage, applying a hydrophilic substance to the yarn on these machines, and then causing a crosslinking reaction by dry curing, etc. When the knitted fabric in which the fiber yarn (I) and the fiber yarn (II) are knitted is hydrophilically processed in the bath simultaneously with dyeing in the dyeing process, the fiber yarn (I) can maintain its hydrophobicity and water repellency while only the fiber yarn (II) is hydrophilized.

[0019] The hydrophilic substance is not particularly limited. For example, when used for hydrophilization treatment of polyester fibers, polyethylene glycol, terephthalic acid, a block copolymer obtained by block polymerization of polyethylene glycol, etc., which are water absorbents having an affinity for polyester fibers, can be used.

[0020] When the total amount of the fiber yarn (I) and the hydrophilic fiber yarn (II) is 100 parts by weight, the weight ratio of the fiber yarn (I) to the hydrophilic fiber yarn (II) is preferably (I):(II)=3:97 to 90:10, more preferably 4:96 to 85:15, and even more preferably 5:95 to 80:20. When the weight ratio of the fiber yarn (I) to the fiber yarn (II) is within the above-described range, it is easy to absorb and retain sweat, and the voids of the through-holes can be maintained when wet.

[0021] The size of the through-hole, which is represented by the average value of the length in the warp direction (the maximum value of the line segment connecting any two points on the outer periphery of the void portion parallel to the warp direction of the knitted fabric) and the length in the weft direction (the maximum value of the line segment connecting any two points on the outer periphery of the void portion parallel to the weft direction of the knitted fabric), is preferably 0.3 to 25 mm, more preferably 0.4 to 20 mm, and even more preferably 0.5 to 15 mm. Thereby, the effective sweating amount is increased by promoting the vaporization of sweat on the skin, the exercise performance is not reduced, and it can be worn comfortably even when sweating.

[0022] On the back surface of the knitted fabric for clothing, the distance in the warp direction between adjacent through-holes (hereinafter also referred to as the pitch in the warp direction) is not particularly limited. For example, from the viewpoint of air permeability, it is preferably 3 to 10 mm, more preferably 4 to 9 mm, and even more preferably 5 to 8 mm. Also, on the back surface of the knitted fabric for clothing, the distance in the weft direction between adjacent through-holes (hereinafter also referred to as the pitch in the weft direction) is not particularly limited. For example, from the viewpoint of air permeability, it is preferably 3 to 10 mm, more preferably 4 to 9 mm, and even more preferably 5 to 8 mm.

[0023] The knitted fabric for clothing has an uneven structure on the back surface, and the convex portions of the uneven structure are composed of a plurality of needle loops. The height of each needle loop constituting each convex portion is 0.8 mm or more. Since the height of the needle loops constituting the convex portions is 0.8 mm or more, an air layer is easily formed between the knitted fabric and the body (skin), and the point contact property between the knitted fabric and the body (skin) is improved, resulting in excellent heat retention and the ability to suppress sweating and chills. Further, the uneven structure on the back surface may include a plurality of needle loops (convex portions) having different heights. As a result, the height of the convex portions on the back surface becomes uneven, and the point contact property between the knitted fabric and the skin is improved, thereby enhancing the quick-drying property and suppressing the feeling of wetness and sweating and chills. In this specification, in the uneven structure on the back surface of the knitted fabric for clothing, the height of the needle loops constituting the convex portions can be measured as described in the examples.

[0024] In the uneven structure on the back surface of the knitted fabric for clothing, the height of the needle loops (convex portions) adjacent in the vertical or horizontal direction of the through hole is 0.8 to 2.0 mm. Since the height of the needle loops adjacent in the vertical or horizontal direction of the through hole is 2.0 mm or less, even in a wet state such as when the knitted fabric for clothing is wet with sweat, the needle loops adjacent to the vertical or horizontal direction of the through hole are not easily fallen, the through hole is not blocked, and the air permeability can be maintained. The height of the needle loops (convex portions) adjacent in the vertical or horizontal direction of the through hole is preferably 1.9 mm or less, more preferably 1.8 mm or less, further preferably 1.7 mm or less, even more preferably 1.6 mm or less, and even more preferably 1.5 mm or less.

[0025] In the back surface uneven structure of the knitted fabric for clothing, the height of other needle loops (convex portions) other than the loops adjacent to the through holes in the vertical direction or the horizontal direction of the through holes is preferably 0.9 mm or more, and preferably 1.0 mm or more, from the viewpoints of heat retention and prevention of cold sweating. Further, the height of the needle loops (convex portions) in a column in a vertical or horizontal direction different from the column in which the through holes are formed is preferably 1.4 mm or more, more preferably 1.5 mm or more, and preferably 1.6 mm or more, from the viewpoints of heat retention and prevention of cold sweating.

[0026] In the back surface uneven structure of the knitted fabric for clothing, the height of other needle loops (convex portions) other than the needle loops (convex portions) adjacent to the through holes in the vertical direction or the horizontal direction of the through holes is preferably 1.0 mm or more, and more preferably 1.2 mm or more, from the viewpoint of texture. Further, in the back surface uneven structure of the knitted fabric for clothing, if the difference in height between the other needle loops (convex portions) other than the needle loops (convex portions) adjacent to the through holes in the vertical direction or the horizontal direction of the through holes and the needle loops (convex portions) adjacent to the through holes in the vertical direction or the horizontal direction is too large, there will be a portion where it is difficult for the fabric to come into contact with the skin, and from the viewpoint that the area for treating the sweat staying on the skin will decrease, it is preferably 3.5 mm or less, and more preferably 3.0 mm or less.

[0027] In the back surface uneven structure of the knitted fabric for clothing, the height of other needle loops (convex portions) other than the needle loops (convex portions) adjacent to the through holes in the vertical direction or the horizontal direction of the through holes is preferably higher than the height of the needle loops (convex portions) adjacent to the through holes in the vertical direction or the horizontal direction of the through holes. When the height of the needle loops adjacent to the through holes is low, the air permeability and quick-drying property when wet are increased. When the height of other needle loops other than the needle loops adjacent to the through holes is high, the heat retention is increased and cold sweating can be suppressed. Therefore, it has excellent heat retention, is easy to enhance the air permeability and quick-drying property when wet, and is also easy to suppress the feeling of wetness and cold sweating.

[0028] On the surface of the knitted fabric for clothing, the height of the needle loops is not particularly limited, and for example, it may be 0.8 mm or less.

[0029] In the knitted fabric for clothing, the uneven structure on the back surface may be formed from the perspective of the fabric texture, such as the utilization of mistakes and tacks, changing the knitting steps with yarns, and combinations of yarns with different thicknesses. It may also be formed from the perspective of fabric processing, such as needle cloth raising, peach raising, and weight reduction processing. As an example of forming an uneven structure from the perspective of the fabric texture, by utilizing mistakes and tacks, etc., a non-smooth texture like a mesh can be formed on the back surface of the fabric, and it is possible to improve the point contact property. Also, by combining yarns with different thicknesses, even in a simple texture such as plain knitting or smoothness, the thick yarns can become convex parts, and it is possible to form an uneven structure. As an example of forming an uneven structure from the perspective of fabric processing, it is also possible to form an uneven structure like fleece by raising processing such as needle cloth raising and peach raising.

[0030] When the knitted fabric for clothing is placed on a horizontal plane in a wet state, it is preferable that the through holes maintain voids. In the knitted fabric for clothing, when the heights of a plurality of needle loops (convex parts) forming the back surface uneven structure satisfy the above-mentioned range in the parts adjacent in the vertical or horizontal direction of the through holes and other parts, in the wet state, the through holes maintain voids, maintain the through state in the thickness direction, and the processability of liquid sweat (moisture) is enhanced.

[0031] The knitted fabric for clothing preferably has a water absorption time measured according to JIS L 1907 A method (dripping method) of 180 seconds or less, more preferably 60 seconds or less, even more preferably 40 seconds or less, even more preferably 20 seconds or less, even more preferably 10 seconds or less, and particularly preferably 5 seconds or less. When sweating, it can quickly absorb sweat, the sweat processability is enhanced, and it can be worn comfortably even when sweating.

[0032] The thickness of the knitted fabric for clothing is not particularly limited, but from the viewpoints of heat retention and breathability when wet, for example, it is preferably 0.8 to 2.5 mm under the condition of a load of 60 g. From the viewpoint of easily exhibiting heat retention for comfortable movement even when exercising in a cold environment, the knitted fabric for clothing preferably has a thickness of 1.0 mm or more, more preferably 1.1 mm or more, and even more preferably 1.2 mm or more. Further, from the viewpoint of enhancing breathability for treating liquid-phase sweating during exercise, the thickness is preferably 1.6 mm or less, more preferably 1.5 mm or less, and even more preferably 1.3 mm or less.

[0033] The weight (areal density) per unit area of the knitted fabric for clothing is, from the viewpoints of heat retention and breathability when wet, preferably, for example, 100 to 200 g / m 2 From the viewpoint of easily exhibiting heat retention for comfortable movement even when exercising in a cold environment, the areal density is preferably 110 g / m 2 or more, more preferably 120 g / m 2 or more, and even more preferably 130 g / m 2 or more. Further, from the viewpoint of enhancing breathability for treating liquid-phase sweating during exercise, the areal density is preferably 190 g / m 2 or less, more preferably 180 g / m 2 or less.

[0034] Generally, a knitted fabric with a greater thickness improves heat retention, so a thicker one is desirable for heat retention. Generally, as the knitted fabric becomes thicker, the knitted fabric weight (areal density) becomes heavier. However, since the knitted fabric for clothing of the present invention has an uneven structure on the back surface, when compared with a knitted fabric of a generally similar areal density, the areal density per unit thickness (bulk density) can be suppressed, and it is possible to provide a garment such as a lightweight and bulky wear. Also, in the spring, autumn, and winter sports scenes where the areal density becomes too heavy due to overemphasis on heat retention and the weight load during exercise tends to be large, by using the knitted fabric for clothing of the present invention, which is excellent in lightweight and bulkiness, light and easy movement is made possible.

[0035] The woven fabric for clothing is not particularly limited. For example, from the viewpoint of easily achieving both heat retention and lightness and bulkiness, the basis weight (volume density) per unit thickness is preferably 0.09 to 0.18 g / cm 3 , more preferably 0.10 to 0.17 g / cm 3 , and even more preferably 0.11 to 0.16 g / cm 3 .

[0036] The air permeability of the woven fabric for clothing in a wet state is not particularly limited. For example, from the viewpoint of facilitating the passage of liquid sweat (moisture) from inside the clothing to the outside of the clothing and enhancing the sweat handling property during sweating, it is preferably 0.30 kPa·s / m or less, more preferably 0.2 kPa·s / m or less, and even more preferably 0.10 kPa·s / m or less. The lower limit of the air permeability of the woven fabric for clothing in a wet state is not particularly limited. For example, from the viewpoint of considering heat retention, it may be 0.40 kPa·s / m or more. In this specification, the air permeability of the woven fabric for clothing in a wet state can be measured as described in the examples.

[0037] The clo value of the woven fabric for clothing is not particularly limited. For example, from the viewpoint of further enhancing heat retention, it is preferably 0.90 or more, more preferably 0.91 or more, and even more preferably 0.92 or more. In this specification, the clo value of the woven fabric for clothing can be measured as described in the examples.

[0038] The woven fabric for clothing is not particularly limited. For example, from the viewpoint of enhancing quick-drying property, the time until the residual moisture rate measured according to the ISO17617 A-1 method reaches 10% is preferably 60 seconds or less, and more preferably 55 seconds or less.

[0039] The knitted fabric for clothing is not particularly limited and may be any knitted fabric. As long as it is a knitted fabric, it has through-holes and can realize an uneven structure while having a certain thickness or more. For example, it includes circular knitting, weft knitting, warp knitting (including tricot knitting and raschel knitting), pile knitting, etc., and is based on plain knitting, honeycomb knitting, rib knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting, denim weave, cord weave, atlas weave, lock stitch, inserted weave, etc., and through-holes can be formed in the warp, weft, or one diagonal direction. Among these, warp knitting such as tricot and raschel, weft knitting, circular knitting, pile knitting, etc. are preferred, and pile knitting is more preferred.

[0040] The clothing of the present invention includes the knitted fabric for clothing. The clothing is not particularly limited and may be worn on the upper body, lower body, or the whole body. For example, shirts, T-shirts, inner shirts, training warmers, briefs, tights, etc. can be mentioned. It can be preferably used for sports clothing used especially in seasons with low outside air temperatures such as spring, autumn, and winter. In the clothing of the present invention, the knitted fabric for clothing may be used entirely or partially. For example, it can be partially used in areas such as the armpits and back where sweating is easy.

[0041] The clothing is excellent in water absorption and quick drying, breathability when wet, and heat retention, and can suppress cold sweats. By wearing the clothing in seasons with low outside air temperatures such as spring, autumn, and winter, it can reduce the discomfort that is likely to occur in each scene such as the beginning, middle, and end of exercise, and can provide comfort from the beginning to the end of exercise.

[0042] Hereinafter, based on the drawings, a woven fabric for clothing according to an embodiment of the present invention will be described. Hereinafter, in the drawings, the same reference numerals denote the same configurations. FIG. 1 is a schematic front view of a woven fabric for clothing according to an embodiment of the present invention, FIG. 2 is a photograph (magnification: 5 times) of the back surface of the woven fabric for clothing observed obliquely upward at about 45°, and FIG. 3 is a schematic cross-sectional view of the woven fabric for clothing in the I-I direction. As shown in FIGS. 1 to 3, the woven fabric for clothing 1 (pile weave) according to this embodiment has a through hole 2 penetrating in the thickness direction of the woven fabric, and at least a part of the region in contact with the through hole 2 is provided with hydrophobic fiber yarns and / or water-repellent fiber yarns 3, and hydrophilic fiber yarns 4 are arranged in other parts. The woven fabric for clothing 1 has an uneven structure 5 on the back surface. Specifically, the woven fabric for clothing 1 is a pile weave, and on the back surface, loop piles (needle loops) constitute the convex portions. In this embodiment, the height of the loop piles adjacent in the longitudinal direction or the transverse direction of the through hole 2 is lower than the height of the loop piles in other parts.

[0049] (Air permeability in the wet state) Using an air permeability tester KES-F8 (manufactured by Kato Tech Co., Ltd.), the air permeability resistance was measured. This measurement was performed by discharging and sucking air into the atmosphere, detecting the pressure during discharge and suction, and calculating the air permeability resistance R. Air volume: 4 cc / cm 2 / sec. (constant air volume method), air hole area: 2π cm 2 It was measured under the conditions of a temperature of 20°C and a relative humidity of 65%. The air permeability resistance in the wet state was measured with the air discharge and suction direction parallel to the ground while the knitted fabric was wetted with water. The temperature and humidity were the same as above. The measurement method is as follows. (1) The knitted fabric was immersed in the water in the water tank, and 300 parts by weight of water was absorbed per 100 parts by weight of the knitted fabric. (2) The knitted fabric that had absorbed water was installed in the tester so that the knitted fabric was perpendicular to the ground (that is, the thickness direction of the knitted fabric was parallel to the ground). (3) The air permeability resistance was measured by a method conforming to the test manual of KES.

[0050] (Thermal insulation) Using KES-F7 Thermo Labo II type (manufactured by Kato Tech Co., Ltd.), the thermal insulation of the knitted fabric was measured. Specifically, the clo value was measured under the conditions of a wind speed of 30 cm / sec, a hot plate temperature of 40°C, an environmental temperature of 20°C, and a relative humidity of 65%. The clo value is a general value for evaluating thermal insulation, and a higher clo value indicates higher thermal insulation.

[0051] (Through-hole structure) The back surface of the knitted fabric was observed with a digital microscope VHX8000 (manufactured by Keyence Corporation), and the length in the vertical direction, the length in the horizontal direction, the pitch in the vertical direction, and the pitch in the horizontal direction of the through-holes were measured with the digital microscope VHX8000 (manufactured by Keyence Corporation).

[0052] (Back surface structure) <Standard state> (1) Observe the back surface of the knitted fabric with a digital microscope VHX8000 (manufactured by Keyence Corporation), and confirm the types of needle loops (protrusions) in the vertical and horizontal directions within the measurement range. The measurement range was set to a range with a length of 5.7 mm in the vertical direction and a length of 7.0 mm in the horizontal direction. When the knitted fabric has through holes, align the upper left of the measurement range with one through hole so that at least two or more through holes are included within the measurement range. In the case of a pile knit knitted fabric, the loop pile becomes the protrusion. (2) Measure the height of each type of needle loop within the measurement range with a one-shot 3D shape measuring machine VR6000 (manufactured by Keyence Corporation), perform multiple measurements for each needle loop, and calculate the average value. (3) Record the results of the height of each needle loop at the corresponding location within the measurement range. <Wet state> (1) Immerse the knitted fabric in a water tank for 10 seconds, then leave the sample hanging for 30 seconds, and absorb 300 parts by weight of water with respect to 100 parts by weight of the knitted fabric to obtain a wet knitted fabric. (2) Except for using the wet knitted fabric, measure the height of each type of needle loop within the measurement range in the same manner as in the standard state with a one-shot 3D shape measuring machine VR6000 (manufactured by Keyence Corporation), perform multiple measurements for each needle loop, and calculate the average value. (3) Record the results of the height of each needle loop at the corresponding location within the measurement range.

[0053] (Examples 1 - 2) For the ground yarn and the pile yarn, the fiber yarns shown in Table 1 below were used to produce a woven fabric (pile fabric) with a through-hole and having the weave structure shown in Table 1 below. The woven fabric portion including the through-hole was made of water-repellent polyester fiber yarn. In Table 1 below, the hydrophilic polyester fiber yarn is obtained by hydrophilically treating a polyester fiber yarn with a hydrophilic polyester resin processing agent, and the water-repellent polyester fiber yarn is obtained by water-repellent processing of a polyester fiber yarn with a fluorine-based water-repellent agent. The front and back surfaces of the woven fabrics of Examples 1 and 2 are as shown in FIG. 4. In Examples 1 and 2, by providing a portion where the knitting step of the pile yarn arranged on the back surface is knitted in a state longer than normal, the portion other than the portion where the yarns are in contact by knitting becomes longer, and a high loop pile with a high height is formed, forming an uneven structure.

[0054] (Comparative Example 1) Using the fiber yarns shown in Table 1 below, a woven fabric having a through-hole and having the weave structure shown in Table 1 below was produced. The woven fabric portion including the through-hole was made of water-repellent polyester fiber yarn. The front and back surfaces of the woven fabric of Comparative Example 1 are as shown in FIG. 5.

[0055] (Comparative Example 2) For the ground yarn and the pile yarn, the fiber yarns shown in Table 1 below were used to produce a woven fabric (pile fabric) having the weave structure shown in Table 1 below. The entire woven fabric was made of hydrophilic fiber yarn. The front and back surfaces of the woven fabric of Comparative Example 2 are as shown in FIG. 5.

[0056] (Comparative Example 3) For the ground yarn and the pile yarn, the fiber yarns shown in Table 1 below were used to produce a woven fabric (pile fabric) with a through-hole and having the weave structure shown in Table 1 below. The entire woven fabric was made of hydrophilic fiber yarn. The front and back surfaces of the woven fabric of Comparative Example 3 are as shown in FIG. 5.

[0057] The thickness, areal density, water absorbency, quick-drying property, breathability in the wet state, and heat retention property of the knitted fabrics obtained in Examples 1 to 2 and Comparative Examples 1 to 3 were measured as described above, and the results are shown in Table 1 below. Also, the through-hole structure and the back surface structure of the knitted fabrics obtained in Examples 1 to 2 and Comparative Examples 1 and 3 were measured and evaluated as described above, and the results are shown in Table 2 below. Further, the back surface structure of the knitted fabrics obtained in Examples 1 to 2 and Comparative Examples 1 to 3 was measured and evaluated as described above, and the results are shown in Tables 2 and 3 below.

[0058] [Table 1]

[0059] [Table 2]

[0060] [Table 3]

[0061] Fig. 6 shows a measurement example of the height of a row of horizontal needle loops on the back surface of the knitted fabric of Example 1 by a one-shot 3D shape measuring machine VR6000 (manufactured by Keyence Corporation). In Fig. 6, a1 and a2 correspond to the through-holes with a height of "0.0 mm" in Table 2, b corresponds to the needle loop adjacent to the through-hole with a height of "0.8 mm" in Table 2, and c1 to c5 correspond to the needle loop loops with a height of "1.3 mm" in Table 2.

[0062] As can be seen from Tables 1 to 3 above, the knitted fabrics of the examples having through-holes, an uneven structure including needle loops (loop piles) with a height of 0.8 mm or more on the back surface, and the height of adjacent needle loops (loop piles) in the vertical or horizontal direction of the through-holes being 0.8 to 2.0 mm were excellent in water absorption and quick-drying properties and heat retention property, and also had good breathability in the wet state. Further, due to the point contact property between the knitted fabric with the back surface uneven structure and the body (skin), sweating and chilling can also be suppressed. On the one hand, the knitted fabric of Comparative Example 1, which has through-holes but no uneven structure on the back surface, has good water absorption and quick drying properties and good air permeability in the wet state, but poor heat retention. In addition, the knitted fabric of Comparative Example 2, which has no through-holes, has good heat retention but poor air permeability in the wet state. Also, since it does not contain water-repellent fiber yarns or hydrophobic fiber yarns and is composed only of hydrophilic fiber yarns, although the water absorption is good, the quick drying property is poor. Further, the knitted fabric of Comparative Example 3, which has through-holes and an uneven structure including needle loops (loop piles) with a height of 0.8 mm or more on the back surface, but the height of the needle loops (loop piles) adjacent in the vertical or horizontal direction of the through-holes exceeds 2.0 mm, has good heat retention but poor air permeability in the wet state. Also, since it does not contain water-repellent fiber yarns or hydrophobic fiber yarns and is composed only of hydrophilic fiber yarns, although the water absorption is good, the quick drying property is poor.

[0063] Next, shirts shown in FIGS. 7 and 8 were sewn using the knitted fabrics of Example 1, Comparative Example 1, and Comparative Example 2, and a wearing test was conducted. The wearing test was carried out in the Kansai area from early March to early April. The target shirt was worn (nothing was worn on the skin side under the target shirt), and running was performed at a speed of 4 - 6 min / km for 45 minutes. The subjects were 5 healthy Japanese men in their 20s to 40s. The comfort from the start of exercise to immediately after the end was evaluated by a sensory test (SD method, bipolar scale, 5 levels). The results are shown in Table 5 below. The evaluation items are as follows. Immediately after the start of exercise: (1) Warmth After the mid-stage of exercise (from the occurrence of sweating to the end of exercise): (2) Feeling of sweat treatment, (3) Feeling of ventilation, (4) Feeling of wetness of the knitted fabric due to sweat Immediately after the end of exercise: (5) Feeling of cold due to sweat From the start to immediately after the end of the whole exercise: (6) Overall comfort The evaluation criteria were set as -2 (bad), -1 (slightly bad), 0 (ordinary), 1 (slightly good), and 2 (good).

[0064]

Table 4

[0065] As can be seen from Table 4 above, when wearing a shirt using the knitted fabric of the example, warmth can be felt immediately after the start of exercise where heat retention is required. After the mid-stage of exercise when sweating, the sweat treatment feeling and ventilation feeling are good, the wet feeling of the knitted fabric due to sweat is suppressed, and immediately after the end of exercise, the cold feeling due to sweat is suppressed. Comfort can be provided in any exercise phase from immediately after the start of exercise to immediately after the end of exercise. When wearing a shirt using the knitted fabric of Comparative Example 1, the wet feeling and cold feeling of the knitted fabric due to sweat cannot be suppressed. When wearing a shirt using the knitted fabric of Comparative Example 2, the air permeability after the mid-stage of exercise when sweating is poor, and there is a cold feeling due to sweat immediately after the end of exercise.
