Description

Technical Field

[0001] The present invention relates to a fabric capable of maintaining a long cooling time due to the heat of vaporization effect, and a fabric product using the same. More specifically, the present invention relates to a fabric that reduces the perceived temperature using the heat of vaporization effect, and fabric products such as clothes using this fabric.

[0002] Conventionally, as a fabric that quickly absorbs moisture, has excellent quick-drying properties, has no stickiness or discomfort due to sweating, has a soft texture of natural fibers, and has a high persistence of the cooling effect, a surface layer composed of surface yarns containing hydrophilic fiber yarns, a back surface layer composed of back yarns made of fiber yarns in which water-absorbent fiber yarns are coated with non-water-absorbent fibers, and an intermediate layer disposed between the surface layer and the back surface layer and composed of connecting yarns made of water-absorbent fiber yarns are provided. The connecting yarns constituting the intermediate layer connect the surface yarns constituting the surface layer and the back yarns constituting the back surface layer and are integrally formed. The back yarns are made of fiber yarns in which polyester fiber yarns or acrylic fiber yarns are used as the core material as water-absorbent fiber yarns, and the outer periphery thereof is coated with a fiber yarn obtained by mixing polyester and silicon dioxide aerogel as non-water-absorbent fibers to form an outer layer portion (see Patent Document 1).

[0003] According to this fabric, moisture is quickly absorbed, it has excellent quick-drying properties and is difficult to get wet, there is no stickiness or discomfort due to sweating, it has a soft texture of natural fibers, and the persistence of the cooling effect is high. Therefore, when used as clothes, a comfortable wearing feeling can be maintained. That is, in Patent Document 1, since the perceived temperature can be lowered by utilizing the heat of vaporization effect, not only training wear for exercise but also clothes worn in daily life can be provided with a natural texture, high quick-drying properties, high moisture absorption capacity and storage capacity, and a novel fabric that exhibits a vaporization cooling effect and clothes using this fabric.

[0004] Incidentally, with the proposal of the fabric and clothing using the fabric described in Patent Document 1, there is a need for proposals for wearable cooling materials and clothing using the same that can further enhance the sustainability of the cooling effect, which is one of the functions of this fabric, and maintain a comfortable wearing experience for a longer period of time. In other words, in Patent Document 1, the surface layer, which has water-retaining properties, can contain moisture, but if the wearer of the clothing does not sweat sufficiently, it is difficult to continuously generate evaporative cooling, and the evaporative cooling effect cannot be efficiently exerted for a long time. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Patent No. 7637449 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] This invention was developed in view of the above-mentioned circumstances in the conventional era, and aims to provide a fabric that can sustain a cooling sensation for a long period of time due to the evaporative cooling effect, and a textile product such as clothing using this fabric. [Means for solving the problem]

[0007] To achieve the above objective, a first aspect of the present invention is a fabric comprising a surface layer, a back layer, and an intermediate layer disposed between the surface layer and the back layer, wherein both the surface layer and the back layer are composed of surface layer yarns or back layer yarns made of fiber yarns that constitute the outer layer by coating the outer circumference of a water-absorbing fiber yarn with a polyester fiber yarn or acrylic fiber yarn as a core material with a fiber yarn made of a mixture of polyester and silicon dioxide aerogel as a non-water-absorbing fiber, the intermediate layer is composed of middle layer yarns that include hydrophilic fiber yarn, and the surface layer, the intermediate layer and the back layer are formed to be held together integrally using connecting yarns made of water-absorbing fiber yarn.

[0008] Furthermore, a second aspect of the present invention is a fabric formed by combining the other side layers of a first fabric and a second fabric, wherein the first fabric and the second fabric are formed by combining the other side layers of a first fabric and a second fabric, wherein the first fabric becomes the surface layer, the first fabric becomes the back layer, the other side layer of the second fabric becomes the back layer, and the other side layer of the first fabric and the other side layer of the second fabric, which are combined together, become the intermediate layer, and the first fabric and the second fabric are formed to be held together integrally using connecting threads made of water-absorbing fibers.

[0009] Furthermore, a third aspect of the present invention is a fabric characterized in that the other side layer of the first fabric and the other side layer of the second fabric are bonded to each other with a water-absorbing fabric layer made of fiber yarn containing hydrophilic fiber yarn sandwiched in between.

[0010] In the fabric according to the first to third aspects of the present invention described above, it is preferable that the surface layer and / or the back layer are treated with an antistatic coating. Furthermore, in the fabric according to the first to third embodiments of the present invention described above, it is preferable that the surface layer and / or the back layer are treated with an antistatic coating.

[0011] Furthermore, the fabrics described above in the first to third embodiments of the present invention can be used in clothing or other textile products, at least in part thereof. [Effects of the Invention]

[0012] According to this invention, moisture absorbed from both the surface and back layers is stored not only in the surface and back layers but also in the intermediate layer, allowing more moisture to be retained within the dough. Furthermore, in the evaporative cooling effect caused by the evaporation of moisture from the dough, the moisture retained within the dough can be used to continuously generate vaporization in the surface layer through capillary action. Therefore, it is possible to provide a fabric that can maintain a cooling effect for a long period of time due to the evaporative cooling effect, and textile products such as clothing that use this fabric.

[Figure 6] This is a schematic diagram illustrating an example of another fabric structure related to the present invention. [Modes for carrying out the invention]

[0014] The following describes an example of an embodiment for implementing the fabric according to the present invention, based on the drawings. The embodiments described below are preferred examples of the present invention and are subject to various technical limitations. However, the scope of the present invention is not limited to these forms unless otherwise specified in the following description.

[0015] <First Embodiment> As shown in Fig. 1, the fabric 1 in this embodiment includes a surface layer 2, a back layer 3, and an intermediate layer 4, and the surface layer 2, the back layer 3, and the intermediate layer 4 are formed to be integrally held using connecting yarns 51. Fig. 1 is a schematic diagram for explaining an example of the structure of the fabric 1 according to this embodiment.

[0016] In this embodiment, the surface layer 2 is composed of surface layer yarns 21 made of water-absorbent fiber yarns coated with non-water-absorbent fibers. Also, the back layer 3, similar to the surface layer 2, is composed of back layer yarns 31 made of water-absorbent fiber yarns coated with non-water-absorbent fibers. The intermediate layer 4 is composed of intermediate layer yarns 41 containing hydrophilic fiber yarns. The connecting yarns 51 are made of water-absorbent fiber yarns.

[0017] That is, the intermediate layer 4 is disposed between the surface layer 2 and the back layer 3, and the connecting yarns 51 connect the surface layer yarns 21 constituting the surface layer 2, the intermediate layer yarns 41 constituting the intermediate layer 4, and the back layer yarns 31 constituting the back layer 3, forming the fabric 1 in which the surface layer 2, the intermediate layer 4, and the back layer 3 are integrally formed.

[0018] In this embodiment, the fabric 1 can be formed to be integrally held by manufacturing the surface layer 2, the intermediate layer 4, and the back layer 3 respectively and sewing them together by hand or machine using the connecting yarns 51. Also, the surface layer 2, the back layer 3, and the intermediate layer 4 constituting the fabric 1 may be woven fabrics or knitted fabrics.

[0019] Also, in Fig. 1, for the purpose of helping to understand the structure of the fabric 1, the surface layer 2, the back layer 3, the intermediate layer 4, and the connecting yarns 51 are emphasized and shown, but the surface layer yarns 21 of the surface layer 2, the back layer yarns 31 of the back layer 3, and the intermediate layer yarns 41 of the intermediate layer 4 are connected by the connecting yarns 51, forming a single fabric 1. When this fabric 1 is used to manufacture clothing as a textile product, the back layer 3 becomes the side that touches the skin, and the front layer 2 becomes the side that is exposed to the outside.

[0020] Next, in the fabric 1 of this embodiment, the surface layer yarn 21 constituting the surface layer 2, the back layer yarn 31 constituting the back layer 3, the middle layer yarn 41 constituting the intermediate layer 4, and the connecting yarn 51 will be described separately.

[0021] First, both the surface yarn 21 and the backing yarn 31 are the same as the backing yarn in the aforementioned Patent Document 1 (Japanese Patent No. 7637449), which is described as prior art. As shown in Figure 2, they are each composed of a core material 22 (32) and an outer layer portion 23 (33) that covers its outer periphery. Figure 2 is a schematic diagram illustrating the details of the surface yarn 21 and back yarn 31 in the fabric 1 of this embodiment.

[0022] In the surface yarn 21 and back yarn 31, the core material 22 (32) is made of absorbent fiber yarn, and the outer layer 23 (33) is made of non-absorbent fiber yarn. The core material 21 (31), which is made of absorbent fiber yarn, is coated with non-absorbent fiber yarn to form the outer layer 22 (32). The absorbent fiber yarn constituting the core material 22(32) can be, for example, polyester fiber yarn or acrylic fiber yarn. Polyester fiber yarn, which has particularly high water absorption, is considered preferable as the core material 22(32).

[0023] Furthermore, the non-absorbent fiber yarn constituting the outer layer 23(33) is a yarn that does not absorb water or absorbs very little water, and can be, for example, a fiber yarn made by mixing polyester and silicon dioxide aerogel. This silicon dioxide aerogel is a very low-density solid, a porous material prepared in a liquid, that is, a dry porous material obtained by maintaining voids using supercritical drying, and is said to be extremely lightweight and insoluble in water.

[0024] In the case of the surface yarn 21 and the back yarn 31, they are coated as the outer layer 23 of the core material 22(32), respectively, thereby preventing moisture absorbed by the highly absorbent core material 22(32) from penetrating to the outer periphery 23(33). Furthermore, penetration to the outer periphery of the fibers is also inhibited, thereby maintaining the dryness of the outer periphery of the surface yarn 21 and the back yarn 31.

[0025] These surface yarns 21 and back yarns 31 are preferably composed of fiber yarns made from a mixture of polyester raw material and silicon dioxide aerogel powder raw material at a concentration of approximately 0.3 to 1.0%, and it is said that an concentration of 0.5 to 0.8% is particularly optimal for achieving water-resistant properties.

[0026] The intermediate layer yarn 41 is similar to the surface layer yarn in the aforementioned Patent Document 1 (Japanese Patent No. 7637449), which is described as prior art. It contains hydrophilic fiber yarn and has the function of absorbing moisture from the surface layer 2 and back layer 3 sides, storing it inside the intermediate layer 4, and diffusing it laterally within the intermediate layer 4.

[0027] These hydrophilic fibers are fibers that are easily absorbed by water and have high water absorption and moisture absorption properties. Examples include natural fibers such as cotton and linen, regenerated fibers such as rayon, cupro, and lyocell, and semi-synthetic fibers such as acetate. Furthermore, as the hydrophilic fiber included in the middle layer yarn 41, fibers selected from rayon yarn, rayon-cotton blend yarn, or cupro-cotton blend yarn are preferred.

[0028] Furthermore, cotton fibers, which are often cited as hydrophilic fibers, are said to absorb water approximately 20 times more effectively than polyester fibers, which are hydrophobic fibers. Other hydrophilic fibers, such as rayon, are said to absorb water 1.5 times more effectively than cotton, and cupro fibers are said to absorb water 4 times more effectively. The middle layer yarn 41, composed of hydrophilic fiber yarns, has significantly higher water absorption than the surface layer yarn 21 and the back layer yarn 31. Therefore, any moisture absorbed by the back layer yarn 31, which makes up the back layer 3 that touches the skin, is immediately absorbed by the middle layer yarn 41. Consequently, the back layer 3 can always remain dry, resulting in a comfortable skin surface without any feeling of stuffiness.

[0029] In fabric 1, the intermediate layer yarn 41 is preferably made of a fiber yarn spun from rayon, which is a regenerated fiber made from wood pulp, and cotton. This results in an intermediate layer 4 that not only has water absorption but also possesses a silky softness and luster, is lightweight, durable, environmentally friendly, and makes fabric 1 feel good against the skin. It is also said that yarn made solely of rayon, or a blend of cupro and cotton, can be expected to have similar effects and are therefore suitable.

[0030] By using hydrophilic fibers for the middle layer yarn 41, sweat (moisture) generated on the skin side and absorbed by the back layer 3 is absorbed by the middle layer yarn 41 and stored in the intermediate layer 4. Furthermore, the moisture stored in the intermediate layer 4 is transferred to the surface layer 2 and retained there by the function of the connecting yarn 51, which will be described later. The atmosphere to which the surface of the fabric 1 is exposed has lower humidity than the atmosphere to which the back side of the fabric 1 is exposed, so the moisture retained in the surface layer 2 evaporates and is released into the atmosphere.

[0031] Furthermore, the amount of moisture temporarily held in the back layer 3 is less than the amount of moisture held in the intermediate layer 4 and the surface layer 2, and moisture absorbed by the intermediate layer 4 or surface layer 2 rarely returns to the back layer 3.

[0032] Furthermore, the connecting yarn 51 is similar to the connecting yarn in the aforementioned Patent Document 1 (Japanese Patent No. 7637449), which is described as prior art, and employs a water-absorbing fiber yarn with an irregular cross-section. Specifically, the connecting yarn 51 connects the surface layer 2, the back layer 3, and the intermediate layer 4, and is said to have the function of quickly storing (absorbing) the moisture absorbed by the surface yarn 21 of the surface layer 2 and the back yarn 31 of the back layer 3 into the intermediate layer 4. In addition, the connecting yarn 51 is said to have the function of quickly absorbing the moisture absorbed by the back layer 3 from the skin side, storing it in the intermediate layer 4, and transferring it to the surface layer 2.

[0033] The absorbent fibers that make up these connecting threads 51 are hydrophobic fibers, but by giving them an irregular cross-section, the gaps between the fibers increase, and it is believed that moisture enters these gaps through capillary action, resulting in fibers with excellent water absorption. Therefore, they quickly absorb moisture from the back layer 3 that has absorbed moisture from the skin side, and accelerate its movement to the middle layer 4. As the absorbent fiber used as the connecting yarn 51, a polyester fiber with a modified cross-section that is particularly excellent in absorbency and quick-drying properties, as well as providing a cool feeling and being lightweight, is preferred.

[0034] Such fabric 1 has a structure in which an intermediate layer 4 made of highly absorbent fibers is placed between the inner layer 3, which is close to the skin, and the outer layer 2, which is exposed to the air. Therefore, when using this fabric 1, by wetting the fabric 1 (fabric product) once before use (wearing it on the skin), moisture can be efficiently absorbed from both the outer layer 2 and the inner layer 3 sides of the fabric 1, as shown by the thick arrows in Figure 3, and moved toward the intermediate layer 4 to be stored (retained).

[0035] When wearing clothing such as T-shirts made from this fabric 1, excess moisture should be removed by squeezing out the fabric 1, and the intermediate layer 4 should be left with an appropriate amount of moisture.

[0036] Furthermore, by using a fabric 1 (cloth product) with an appropriate amount of moisture in the intermediate layer 4 (worn against the skin), as shown by the thin arrows in Figure 4, the capillary action from the irregularly shaped cross-section of the connecting thread 51 is used to move moisture (sweat) from the back layer 3, which is the side of the fabric 1 closest to the skin, towards the intermediate layer 4 when sweating occurs. In addition, the connecting thread 51 further moves moisture from the intermediate layer 4 towards the surface layer 2, which is the side of the fabric 1 exposed to the air. As a result, moisture evaporates on the surface of the fabric 1 (surface layer 2 side), and the temperature on the back side of the fabric 1 (back layer 3 side) can be lowered by the evaporative cooling effect, while the back side of the fabric 1 closest to the skin (back layer 3 side) can be kept dry.

[0037] In other words, in this fabric 1, moisture on the skin side is absorbed by the back layer yarn 31 of the back layer 3, quickly moved to the intermediate layer 4 by the connecting yarn 51 and stored (retained), preventing the moisture from returning to the back layer 3. Furthermore, the moisture contained in the intermediate layer 4 is moved to the surface layer 2 by the connecting yarn 51 and absorbed by the surface layer yarn 21, and the moisture stored in the surface layer 2 is diffused within the surface layer 2 and evaporated.

[0038] Therefore, the inner layer 3 that comes into contact with the skin becomes dry and comfortable against the skin without causing discomfort, thanks to the quick-drying properties of the outer layer 33 of the inner layer yarn 31. In addition, the outer layer 23 of the outer layer yarn 21 of the outer layer 21 of the outer layer 21 of the outer layer 21 can evaporate moisture through contact with the air. With this fabric 1, even if you are not sweating profusely, the temperature will be lowered by the evaporative cooling effect when the moisture contained in the intermediate layer 4 evaporates.

[0039] Moreover, since the connecting threads 51 of this fabric 1 are composed of absorbent fiber threads with irregular cross-sections, the movement of moisture is accelerated, resulting in a water-absorbing and quick-drying effect throughout the entire fabric 1, and an evaporative cooling phenomenon occurs as the moisture absorbed by the fabric 1 evaporates, drawing heat away from the fabric 1. Furthermore, since the intermediate layer 4 contains a large amount of moisture stored in the hydrophilic fiber yarn, the moisture is replenished by the irregularly shaped cross-section yarn of the connecting yarn 51, and this moisture becomes the source of evaporative cooling. As a result, the back layer 3, which is the surface that touches the skin, is configured to maintain a cool feeling for a long time.

[0040] As described above, in the fabric 1 according to this embodiment, the surface layer 2 is composed of surface yarns 21 and back layer 3 is composed of back layer yarns 31, both of which are made of water-absorbing fiber yarns coated with water-non-water-absorbing fibers, the middle layer 4 is composed of intermediate layer yarns 41 which include hydrophilic fiber yarns, and the connecting yarns 51 are made of water-absorbing fiber yarns, and the surface layer 2, back layer 3 and intermediate layer 4 are connected by the connecting yarns 51 to form an integral structure.

[0041] Therefore, the fabric 1 of this embodiment increases the amount of water it can retain, allowing it to hold more moisture in the intermediate layer 4, thereby extending the cooling effect that can lower the perceived temperature. Moreover, it is a highly desirable material as an environmentally friendly, cooling fabric that does not use electricity or other forms of energy.

[0042] Furthermore, in fabric 1, the surface layer 2 and back layer 3 can be made of polyester fibers that can be processed in various ways. For example, an antistatic treatment can be applied to the surface layer 2 and back layer 3 by appropriate means such as coating or immersion with a commercially available antistatic agent. This reduces the risk of airborne dust and other particles adhering to the surface, making it less prone to getting dirty.

[0043] Furthermore, in addition to or instead of antistatic treatment, fabric 1 may be treated by applying or immersing a commercially available antistatic agent to the surface layer 2 or back layer 3 by appropriate means. This effectively prevents the generation of static electricity, thus preventing dust accumulation due to friction (i.e., dust adhesion due to static electricity), and eliminates the unpleasant crackling sensation caused by static discharge. In other words, by using a fabric that does not carry static electricity, it becomes possible to use the fabric in areas where explosion protection is required (i.e., use in clothing and other fabric products). Furthermore, in fabric 1, the surface layer 2 and the back layer 3 may be treated with water-repellent or antibacterial processing.

[0044] <Second Embodiment> Furthermore, in this invention, the amount of water retained inside the fabric can be further increased to maintain a longer cooling effect. In other words, the configuration of the intermediate layer 4 is different from that of the first embodiment described above.

[0045] In the other embodiments described below, the focus will be on the differences from the first embodiment described above. Therefore, components similar to those in the first embodiment will be given different reference numerals but will be described using the same terminology, and their descriptions will be omitted unless otherwise specified.

[0046] As shown in Figure 5, the fabric 10 in this embodiment is constructed by combining two pieces of fabric: a first fabric 11 and a second fabric 12. Figure 5 is a schematic diagram illustrating an example of the structure of another fabric 10 according to the present invention, where (A) is a schematic diagram illustrating the two fabrics 11 and 12 before combination, and (B) is a schematic diagram illustrating the combination of the two fabrics 11 and 12.

[0047] Specifically, Figure 5(A) shows a first fabric 11 comprising one side layer 11-1 and another side layer 11-2, and a second fabric 12 comprising one side layer 12-1 and another side layer 12-2. Figure 5(B) shows a fabric 1 formed by combining the other side layer 11-2 of the first fabric 11 and the other side layer 12-2 of the second fabric 12.

[0048] In this embodiment, the fabric 10 is formed by separately manufacturing a first fabric 11 and a second fabric 12, and then combining them so that they are held together as a single unit by hand sewing or machine sewing with connecting thread 51.

[0049] The first fabric 11 has one side layer 11-1 composed of fiber yarn in which water-absorbent fiber yarn is coated with water-non-absorbent fiber, and the other side layer 11-2 composed of fiber yarn including hydrophilic fiber yarn. Similarly, the second fabric 12 also has one side layer 12-1 composed of fiber yarn in which water-absorbent fiber yarn is coated with water-non-absorbent fiber, and the other side layer 12-2 composed of fiber yarn including hydrophilic fiber yarn.

[0050] In this way, the fabric 10, which is constructed by combining two fabrics (the first fabric 11 and the second fabric 12), has one side 11-1 of the first fabric 11 as the surface layer 2, one side 12-1 of the second fabric 12 as the back layer 3, and the other side layers 11-2 of the first fabric 11 and 12-2 of the second fabric 12, which are bonded together, as the intermediate layer 4.

[0051] Furthermore, the fiber yarns constituting the one-sided side layer 11-1 of the first fabric 11 and the fiber yarns constituting the one-sided side layer 12-1 of the second fabric 12 can both be made in the same way as the first embodiment described above, with polyester fiber yarn or acrylic fiber yarn as the core material 22(32) as the water-absorbing fiber yarn, and the outer periphery thereon coated with fiber yarn mixed with polyester and silicon dioxide aerogel as a non-water-absorbing fiber to constitute the outer layer 23(33).

[0052] Furthermore, in the fabric 10, one side 11-1 of the first fabric 11 which becomes the surface layer 2, and one side 12-1 of the second fabric 12 which becomes the back layer 3, can be made of polyester fibers that can be subjected to various fabric processing. For example, one side 11-1 of the first fabric 11 and one side 12-1 of the second fabric 12 may be treated with antistatic processing, anti-static processing, water-repellent processing, antibacterial processing, etc.

[0053] <Third Embodiment> Furthermore, in this invention, a configuration different from the second embodiment described above can be used to further increase the amount of water retained inside the fabric compared to the first embodiment described above, thereby maintaining a longer cooling time. In other words, the configuration of the intermediate layer 4 is different from that of the second embodiment described above.

[0054] As shown in Figure 6, the fabric 100 in this embodiment is constructed by combining two fabrics, a first fabric 11 and a second fabric 12, as illustrated in the second embodiment described above. An absorbent fabric layer 13 is sandwiched between the other side layer 11-2 of the first fabric 11 and the other side layer 12-2 of the second fabric 12, forming a three-layer intermediate layer 4.

[0055] In other words, one side 11-1 of the first fabric 11 becomes the surface layer 2, one side 12-1 of the second fabric 12 becomes the back layer 3, and the other side layer 11-2 of the first fabric 11, the absorbent fabric layer 13, and the other side layer 12-2 of the second fabric 12, when combined, form the intermediate layer 4.

[0056] This absorbent fabric layer 13 can be made of fiber yarns containing hydrophilic fiber yarns such as polyester, cotton, or modal (registered trademark), similar to the fiber yarns that make up the other side layer 11-2 of the first fabric 11 and the other side layer 12-2 of the second fabric 12.

[0057] Thus, a major feature of the fabric 100 according to this embodiment is that both the surface layer yarn 21 constituting the surface layer 2 and the back layer yarn 31 constituting the back layer 3 are made of fiber yarns in which water-absorbent fiber yarn is coated with a water-non-water-absorbent fiber, the other side layer 11-2 of the first fabric 11 and the water-absorbent fabric layer 13, and the other side layer 12-2 of the second fabric 12 constituting the intermediate layer 4 are made of middle layer yarn 41 containing hydrophilic fiber yarn, and the connecting yarn 51 is made of water-absorbent fiber yarn.

[0058] Therefore, in the fabric 100 of this embodiment, by further increasing the amount of water retained in the intermediate layer 4, the cooling effect, which lowers the perceived temperature by utilizing the evaporative cooling effect, can be maintained for an even longer period. Furthermore, the intermediate layer 4 sandwiching the absorbent fabric layer 13 is not limited to a three-layer structure as described above, but may be a multi-layer structure in which multiple absorbent fabric layers 13 are stacked on top of each other.

[0059] Furthermore, in fabric 100, one side 11-1 of the first fabric 11 which becomes the surface layer 2, and one side 12-1 of the second fabric 12 which becomes the back layer 3, can be made of polyester fibers that can be subjected to various fabric processing. For example, one side 11-1 of the first fabric 11 and one side 12-1 of the second fabric 12 may be treated with antistatic processing, anti-static processing, water-repellent processing, antibacterial processing, etc.

[0060] As described above, the fabrics 1, 10, and 100 according to this embodiment can be used not only for clothing worn during activities that cause heavy sweating, such as sportswear and work clothes, but also for everyday clothing such as T-shirts, dress shirts, polo shirts, trousers, underwear, undergarments, pajamas, bathrobes, and sportswear. Furthermore, fabric 1 can also be used for various textile products, including clothing that is worn on a part of the body, such as hats, arm covers, masks, sheets, and pillowcases.

[0061] Furthermore, even if the entire garment is manufactured using fabric 1, the evaporative cooling effect can be sufficiently achieved even if only parts of the garment, such as areas that come into contact with sweating areas or areas where sweat tends to accumulate, are manufactured using fabric 1. Furthermore, the fabric 1 according to this embodiment can be used, for example, in covers that cover parts exposed to sunlight, as well as in fabric products such as umbrellas for sun protection and other miscellaneous goods that use this fabric product. Furthermore, clothing includes not only items worn by humans, but also those worn by animals. [Industrial applicability]

[0062] The fabric of this invention has a back layer made of hydrophilic natural fibers, resulting in a pleasant feel against the skin. It can also be made to have a variety of colors and lusters. Therefore, it is expected to be used not only for sportswear and work clothes, but also for all kinds of fabric products worn on parts of the body that require quick-drying properties, such as T-shirts, dress shirts, polo shirts, trousers, underwear, pajamas, bathrobes, hats, arm covers, masks, sheets, pillowcases, and other bedding.
