Description

Technical Field

[0001] The present invention relates to the field of fabric manufacturing technology, and particularly to fabrics and fabric products containing the fabrics.

Background Art

[0002] With the improvement of people's living standards and the increasing awareness of exercise and health, the requirements for the functions of daily clothing, especially sportswear, are on the rise.

[0003] When sweating during exercise or in a high-temperature environment, the sweat remains on the surface of the clothing, forming obvious sweat marks, which damages the appearance cleanliness of the clothing.

[0004] The occurrence of sweat marks mainly has two causes. The first cause is due to the optical properties of the fabric material. When sweat remains on the surface of the fabric, specular reflection occurs when irradiated with light, making some areas of the clothing darker and some areas having a gloss, thus forming visible sweat marks. The second cause is that due to the low hygroscopicity and diffusion ability of the fabric, sweat cannot be effectively absorbed and rapidly diffused, but instead locally accumulates sweat, intensifying the formation of sweat marks. Especially in the case of intense exercise or long exercise time, more obvious sweat marks are formed.

[0005] Patent Document 1 discloses an anti-sweat stain fabric and an anti-sweat stain fabric clothing. The anti-sweat stain fabric is composed of polyester fibers, and an anti-water agent is attached to one surface of the fabric to achieve the anti-sweat stain effect. However, in the method of attaching an anti-water agent to the surface of the fiber, the anti-sweat stain effect is limited.

[0026] Hereinafter, the technical solution of the present invention and the method for solving the above technical problems will be described in detail through specific embodiments. Some of the following specific embodiments can be combined with each other, and for the same or similar concepts or processes, they may not be described in more detail in some embodiments. Hereinafter, the present invention will be described in conjunction with the drawings.

[0027] [Fabric] The fabric 1 according to the first aspect of the present invention includes a laminated structure of a first functional layer 100 and a second functional layer 200. As shown in FIG. 1, the fabric 1 may have the first functional layer 100 and the second functional layer 200 directly laminated, or the first functional layer 100 and the second functional layer 200 may be laminated via other layers.

[0028] (First yarn and first functional layer) The first functional layer 100 is a layer formed from the first yarn 110. The forms of the layer include a woven fabric layer, a non-woven fabric layer, and a knitted fabric layer formed from the first yarn 110.

[0029] The first yarn 110 includes a plurality of functional fibers 10.

[0030] As shown in FIGS. 3 and 4, the functional fiber 10 includes a core layer 11 and a sheath layer 12. The sheath layer 12 is provided on the outer periphery of the core layer 11, shows a protective effect on the core layer 11, and reduces the influence of the external environment such as wear and erosion.

[0031] The sheath layer 12 includes a diffusion reflector 101, and at least a part of the diffusion reflector 101 contained in the sheath layer 12 is exposed on the surface of the sheath layer 12 to form a plurality of diffusion reflection portions 13.

[0032] The diffusion reflection portion 13 is a portion formed by the diffusion reflector 101 exposed on the surface of the sheath layer 12, and has the property of diffusing light and reflecting it in multiple directions.

[0033] The shape of the diffusion reflection portion 13 is, for example, a protrusion shape, a concave groove shape, or a hole shape, and these may be combined and included. The planar shape of the diffusion reflection portion 13 is, for example, circular, square, rhombus, elliptical, trapezoidal, or other shapes.

[0034] The average diameter of the diffusion reflection portion 13 is, for example, in the range of 10 to 3000 nm. The average diameter is preferably in the range constituted by any two points among 10 nm, 20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, 500 nm, 800 nm, 1300 nm, 1500 nm, 2000 nm, 2500 nm, 3000 nm. Incidentally, the average diameter is, for example, the equivalent diameter of the circumscribed circle.

[0035] It is preferable that the plurality of diffusion reflection portions 13 are arranged on the surface of the sheath layer 12 at intervals. The installation positions of the diffusion reflection portions 13 may be random or regular.

[0036] The diffusion reflector 101 forming the diffusion reflection portion 11 is a material having the property of diffusing light and reflecting it in multiple directions, and examples thereof include ceramic powder.

[0037] The ceramic powder contains at least one selected from, for example, titanium oxide, zinc oxide, magnesium oxide, calcium carbonate, silicate, alumina, etc. For example, when the ceramic powder contains zinc oxide or titanium oxide, it absorbs ultraviolet rays and reduces the ultraviolet rays that penetrate into the fiber or reach the skin, and is excellent in enhancing the ultraviolet ray protection function of the yarn and its products.

[0038] The average particle size of the diffusion reflector 101 is, for example, 10 to 3000 nm. The average particle size is preferably in the range constituted by any two points among 10 nm, 20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, 500 nm, 800 nm, 1300 nm, 1500 nm, 2000 nm, 2500 nm, 3000 nm. Incidentally, the average particle size is measured by, for example, the laser diffraction / scattering method. The nano-scale diffusion reflector 101 changes the light scattering characteristics of the yarn, scatters the light on the yarn and its products, and is advantageous for hiding sweat marks.

[0039] When the sheath layer 12 contains the diffusion reflector 101, the surface of the sheath layer 12 becomes uneven and rough, which facilitates the diffuse reflection of light, scatters the light reaching the fabric 1 in multiple directions, and reduces the specular reflection of the fabric 1 including the first yarn 110. As a result, the visible sweat marks are reduced and the appearance cleanliness of the clothing is improved. In addition, since the diffusion reflector 101 can increase the strength and rigidity of the fiber and improve the abrasion resistance and tear resistance of the fiber, it is also advantageous in improving the abrasion resistance and tensile performance of the yarn and the products using the yarn.

[0040] The core layer 11 may contain the diffusion reflector 101, and the diffusion reflector 101 may contain a ceramic powder.

[0041] When the diffusion reflector 101 is contained in at least one of the sheath layer 12 and the core layer 11 of the functional fiber 10, the ultraviolet rays and near-infrared rays irradiated on the yarn are such that the diffusion reflector 101 in the functional fiber 10 absorbs a part of the ultraviolet rays and near-infrared rays and scatters the rest, so that the ultraviolet ray protection ability and heat insulation performance of the fabric 1 including the functional fiber 10 can be enhanced.

[0042] Also, when the diffusion reflective material 101 is contained in at least one of the sheath layer 12 and the core layer 11 of the functional fiber 10, a large number of micropores and passages similar to capillaries can be formed in the functional fiber 10, and moisture can be rapidly diffused along the fiber axis direction and the radial direction, improving the moisture absorption and quick-drying performance of the yarn.

[0043] Furthermore, when the diffusion reflective material 101 is contained in at least one of the sheath layer 12 and the core layer 11 of the functional fiber 10, the diffusion reflective material 101 can increase the strength and rigidity of the fiber, improve the wear resistance and tear resistance of the fiber, and improve the wear resistance and tensile performance of the fabric 1 including the functional fiber 10.

[0044] The content rate of the diffusion reflective material 101 in the core layer 11 and the content rate of the diffusion reflective material 101 in the sheath layer 12 (including the diffusion reflective portion 13) are not particularly limited. However, from the viewpoint of enabling the functional fiber 10 to have good heat shielding ability and ultraviolet ray protection ability, and having a certain flexibility and processability, it is preferable to control the content rate of the diffusion reflective material 101 in the core layer 11 to be equal to the content rate of the diffusion reflective material 101 in the sheath layer 12, or to control it in a range exceeding the content rate of the diffusion reflective material 101 in the sheath layer 12 (for example, exceeding 1 time and being 5 times or less of the content rate of the diffusion reflective material 101 in the sheath layer 12).

[0045] When the diffusion reflective material 101 is included in both the sheath layer 12 and the core layer 11 of the functional fiber 10, more micropores and passages can be formed in the functional fiber 10, promoting the diffusion of moisture along the fiber axis direction and the radial direction, and helping to improve the moisture absorption and quick-drying performance.

[0046] In addition, when the diffusion reflective material 101 is included in both the sheath layer 12 and the core layer 11 of the functional fiber 10, part of the ultraviolet rays and near-infrared rays irradiated on the functional fiber 10 are absorbed by the diffusion reflective material 101 in the core layer 11, and the remaining part is scattered. Thereby, the ultraviolet ray protection ability and heat insulation performance of the fabric 1 are enhanced. Furthermore, the diffusion reflective material 101 can increase the strength and rigidity of the functional fiber 10, improve the wear resistance and tear resistance of the functional fiber 10, and is also advantageous for further improving the wear resistance and tensile performance of the first functional layer 100.

[0047] The diffusion reflective material 101 can increase the strength and rigidity of the functional fiber 10. However, if the diffusion reflective material 101 is added excessively, the flexibility and elasticity of the functional fiber 10 will decrease, the functional fiber 10 will become hard and rough, and the comfort may deteriorate. Therefore, by adjusting the content rate of the diffusion reflective material 101 in the core layer 11 to be equal to or higher than the content rate of the diffusion reflective material 101 in the sheath layer 12, or by suppressing the content rate of the diffusion reflective material 101 in the sheath layer 12, the functional fiber 10 can have a smooth yarn surface and maintain flexibility, while having good toughness and rigidity, and having a certain heat insulation ability and ultraviolet ray protection ability. And it is possible to avoid a decrease in the feel, glossiness, etc. of the fabric 1, which is also advantageous for subsequent processing (such as dyeing).

[0048] The functional fiber 10 has a core-sheath structure, and the sheath layer 12 surrounds the outside of the core layer 11. When the core layer 11, the sheath layer 12, and the diffusion reflection part 13 contain the diffusion reflective material 101, the surface is roughened, so that part of the external light is easily diffusely reflected by the sheath layer 12, and the remaining part penetrates into the micropores of the functional fiber 10 and reaches the core layer 11. However, the ultraviolet rays and near-infrared rays that penetrate into the micropores are continuously reflected in the micropores, part of which is absorbed by the diffusion reflective material 101, and the remaining part reaches the core layer 11 and is diffusely reflected again. Thereby, it is advantageous for the propagation of light rays in the functional fiber 10, and is absorbed by the diffusion reflective material 101, further improving the heat insulation ability and ultraviolet ray protection ability of the fabric 1.

[0049] In addition, the light rays irradiated onto the fabric 1 are diffusely reflected by the sheath layer 12 and the core layer 11 of the functional fiber 10, so that sweat marks are less likely to appear on the fabric 1, the formation of conspicuous sweat marks is reduced, the appearance cleanliness is improved, and the psychological discomfort can be reduced.

[0050] Moreover, the light rays that penetrate the sheath layer 12 are diffusely reflected by the core layer 11. As a result, sweat marks on the fabric 1 are less likely to appear, the formation of conspicuous sweat marks on the surface of the fabric 1 is further reduced, the appearance cleanliness is improved, and the psychological discomfort of people with respect to sweat marks can be reduced.

[0051] The cross-section of the functional fiber 10 may be, for example, a deformed cross-section such as a flat shape, a triangle, and other irregular shapes. The functional fiber 10 with a deformed cross-section tends to have a higher light scattering ability in the sheath layer 12 compared to the functional fiber 10 with a circular cross-section. In addition, the functional fiber 10 may have many micropores and passages. The micropores and passages are advantageous for the diffusion of moisture.

[0052] The diffusion reflector 101 can be incorporated into the fiber, for example, through the following process. That is, before spinning the functional fiber 10, the diffusion reflector 101 is mixed with a polymer solution or melt, and then the functional fiber 10 is manufactured by a spinning process. According to the manufacturing method, the diffusion reflector 101 can be uniformly distributed inside the functional fiber 10.

[0053] The core layer 11 and the sheath layer 12 constituting the functional fiber 10 may be formed of the same fiber material or different fiber materials. In functional clothing such as sportswear, it is advantageous to use cotton yarn, bamboo fiber, or synthetic fiber for the core layer 11 for the absorption and diffusion of sweat by the yarn.

[0054] When both the core layer 11 and the sheath layer 12 constituting the functional fiber 10 are formed of synthetic fibers, the functional fiber 10 may have a structure in which, for example, polyester covers polyester, the core layer 11 may be polyester, and the sheath layer 12 may be polyester, or the functional fiber 10 may have a structure in which polyester covers polyamide (e.g., nylon fiber), the core layer 11 may be polyamide, and the sheath layer 12 may be polyester.

[0055] The first yarn 110 can be manufactured using, for example, filaments (long fibers) or staples (short fibers) as base materials.

[0056] When the first yarn 110 uses filaments (long fibers) as the base material, by adjusting the difference in thickness between the first yarn 110 and the second yarn 210 and increasing the pressure difference between the first functional layer 100 and the second functional layer 200, the sweat discharge rate can be further increased.

[0057] The thickness of the filament is, for example, 5 to 150 D. The above range is preferably a range constituted by any two points among 5 D, 10 D, 20 D, 30 D, 40 D, 50 D, 60 D, 70 D, 80 D, 90 D, 100 D, 110 D, 120 D, 130 D, 140 D, and 150 D.

[0058] When the first yarn 110 uses staples (short fibers) as the base material, the sweat diffusion rate can be increased by increasing the porosity of the fabric 1. Compared with filaments, the single fiber length of staples is short, but the large specific surface area is advantageous for increasing the sweat adsorption and discharge rates.

[0059] The thickness of the staple is, for example, 10 to 50 s. The above range is preferably a range constituted by any two points among 10 s, 20 s, 30 s, 40 s, and 50 s.

[0060] Here, the thickness is an index for measuring the size of yarns or fibers, reflecting the diameter size of yarns or fibers, and having an important influence on the quality and characteristics of fabrics and the like. The main units of thickness are Denier and yarn count (s). Denier is a unit used to represent the thickness of synthetic fibers, rayon, and some natural fibers. 1 Denier is defined as the weight of 1 g of fiber with a length of 9000 meters. That is, the higher the Denier value, the thicker the fiber. Yarn count is a unit mainly used to represent the thickness of cotton yarns. 1 yarn count is defined as the length of 1 pound of fiber at the official moisture regain, and the larger the yarn count, the thinner the yarn.

[0061] The thickness of the first functional layer 100 is, for example, 0.01 - 1 mm. By setting the thickness of the first functional layer 100 within the above range, the structural stability and durability of the fabric 1 can be enhanced, and good air permeability and comfort can be achieved.

[0062] The thickness of the first functional layer 100 is preferably in the range formed by any two points among 0.01 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm.

[0063] The fabric 1 provided with the first functional layer 100 made of the first yarn 110 can avoid the occurrence of obvious sweat stains, maintain a visually clean appearance even when sweating, and reduce the psychological discomfort caused by sweat marks.

[0064] (The second yarn and the second functional layer) The second functional layer 200 is a layer formed from the second yarn 210, and the forms of the layer include a woven fabric layer, a non-woven fabric layer, and a knitted fabric layer formed from the second yarn 210.

[0065] The second yarn 210 has at least one of the functions of a quick-drying function, a ventilation function, and a contact cooling sensation function. The second yarn 210 may have one of the above functions alone, or may have a plurality of the above functions simultaneously.

[0066] When the second functional layer 200 has a quick-drying function, it can accelerate the absorption of sweat, rapidly evaporate the sweat on the surface of the second functional layer 200, and achieve the effect of quick drying.

[0067] The second yarn 210 is, for example, a yarn formed of a fiber material. The fiber material has many micropores and passages. The micropores and passages have properties similar to capillaries and can promote the diffusion of moisture along the axial and radial directions of the fiber. When the second yarn 210 is formed of a fiber material, it can exert the effect of improving the moisture absorption and quick-drying performance.

[0068] The second yarn 210 is preferably at least one yarn selected from cotton yarn, linen yarn, bamboo fiber, and synthetic fiber.

[0069] The synthetic fiber includes, for example, nylon fiber, polyester fiber yarn (including, for example, T400 yarn, PTT yarn, PBT yarn, T8 yarn, etc.), polypropylene fiber yarn, polyethylene fiber yarn, and the like.

[0070] Cotton yarn, linen yarn, bamboo fiber, and synthetic fiber have relatively excellent air permeability and moisture absorption, so the second functional layer 200 formed using them has excellent ventilation function.

[0071] Polypropylene fiber yarn is lightweight, tough, resistant to chemical corrosion, has extremely low water absorption, and is suitable for the manufacture of outdoor equipment and sportswear that require extremely high durability and quick-drying properties.

[0072] The T400 yarn contained in the polyester fiber yarn is a polyester elastic fiber that combines the durability of polyester and the stretchability of elastic fiber, and has the advantages of quick drying and being difficult to deform, and is suitable for the manufacture of sportswear that requires a certain elasticity, such as sports underwear and tights.

[0073] The PTT yarn contained in the polyester fiber yarn is environmentally friendly, has a soft touch and good dyeing performance, and at the same time has excellent elastic recovery force and wrinkle resistance.

[0074] The T8 yarn contained in the polyester fiber yarn has high strength and good elasticity, with a relatively fast drying speed and excellent abrasion resistance, making it suitable for making high-intensity sports wear such as running wear and training wear.

[0075] The PBT yarn contained in the polyester fiber yarn has good elasticity and recovery, and good quick-drying properties.

[0076] The thickness of the second functional layer 200 is, for example, 0.01 - 1 mm. By setting the thickness of the second functional layer 200 of the fabric 1 within the above range, breathability and flexibility can be enhanced, and the diffusion and evaporation rate of moisture can be accelerated.

[0077] The thickness of the second functional layer 200 is preferably in the range formed by any two points among 0.01 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm.

[0078] Since the second functional layer 200 is formed of the second yarn 210 having the above functions, it has at least one of the functions of a quick-drying function, a ventilation function, and a contact cooling feeling function. And the fabric 1 provided with the second functional layer 200 together with the first functional layer 100 not only has the function of hiding sweat, but also has at least one of the functions of a quick-drying function, a ventilation function, and a contact cooling feeling function, enhancing functionality and practicality.

[0079] (Fabric) The fabric 1 includes a laminated structure of a first functional layer 100 and a second functional layer 200.

[0080] When the second functional layer 200 is a functional layer having a quick-drying function, it is preferable to dispose the second functional layer 200 closer to the skin side than the first functional layer 100. If arranged as described above, when a large amount of sweat is generated, the second yarn 210 in the second functional layer 200 absorbs the sweat, and the absorbed sweat diffuses through the second functional layer 200, and the sweat in contact with the air volatilizes and is removed, thereby realizing rapid drying and achieving an excellent sweat-absorbing and ventilating effect.

[0081] There is no particular limitation on the method of connecting the first functional layer 100 and the second functional layer 200. For example, as shown in FIG. 2, a method in which the first functional layer 100 and the second functional layer 200 are connected via a connecting thread 300 can be mentioned. According to this method, the first functional layer 100 and the second functional layer 200 can be stably connected without affecting the overall performance of the functional layer.

[0082] There is no particular limitation on the connecting thread 300 as long as it can connect the second functional layer 200 and the first functional layer 100. The connecting thread 300 can use a thread of a type different from the first thread 110 constituting the first functional layer 100 or the second thread 210 constituting the second functional layer 200.

[0083] As another method of connecting the first functional layer 100 and the second functional layer 200, a method of connecting the first functional layer 100 and the second functional layer 200 by knitting or weaving them together can also be mentioned. In this case, the connecting thread 300 is the first thread 100 and / or the second thread 210.

[0084] By connecting the first functional layer 100 and the second functional layer 200 via the first thread 100 and / or the second thread 210, the diffusion of sweat from the second functional layer 200 to the first functional layer 100 is ensured, which is advantageous for improving the sweat-absorbing and quick-drying performance.

[0085] Using the first thread 110 of the first functional layer 100 or the second thread 210 of the second functional layer 200 as the connecting thread 300, when knitting or weaving the first functional layer 100 and the second functional layer 200, the first functional layer 100 is woven or knitted together using the first thread 110, and the second functional layer 200 is woven or knitted together using the second thread 210, and at the same time, the method of connecting the first functional layer 100 and the second functional layer 200 does not require an additional connecting thread or a sewing process, and the subsequent sewing or bonding process becomes unnecessary, which is preferable in terms of realizing a compact structure. According to the above method, the fabric 1 can be made flatter, the friction and irritation can be reduced, the wearing comfort can be improved, the production process can be simplified, the cost can be reduced, and the waste of materials can be reduced.

[0086] The first functional layer 100 preferably has at least one structure selected from a plain knitting structure, a mesh structure, a stripe structure, and a square structure.

[0087] The second functional layer 200 preferably has at least one structure selected from a plain knitting structure, a mesh structure, a stripe structure, and a square structure.

[0088] The structure of fabric 1 is a knitting structure of yarns, a weaving structure of yarns, or a non-woven fabric structure. Among them, if a plain knitting structure is adopted, good air permeability and quick-drying property can be maintained while strengthening the firmness and durability of fabric 1. If a mesh structure is adopted, the air permeability of fabric 1 can be effectively increased, and sweat can be rapidly evaporated, which is suitable for sportswear. When a stripe structure is adopted, stripes are formed by the arrangement of yarns, which can be in the horizontal, vertical, or diagonal direction, and the air permeability and heat preservation property of fabric 1 can be adjusted according to the density of the yarns. If a square structure is adopted, similar to the mesh structure, the air permeability and quick-drying property of fabric 1 can be increased, and at the same time, a certain elasticity and stretchability can be given to fabric 1.

[0089] Fabric 1 can be customized according to specific usage situations and the needs of target users. For example, when used for summer sportswear, it is preferable to use the first functional layer 100 and the second functional layer 200 with a mesh structure or a square structure to enhance air permeability and quick-drying property. Also, when used for spring and autumn sportswear, it is preferable to adopt a stripe structure or a plain knitting structure to ensure both heat preservation and air permeability.

[0090] From the above, fabric 1 can easily hide sweat marks by reducing the specular reflection on the fabric surface through the first functional layer 100, and the second functional layer 200 also provides functions selected from a quick-drying function, a ventilation function, and a contact cool feeling function. And by using fabric 1, the functions of hiding sweat marks and quick-drying can be effectively combined to provide a fabric product with a better sports experience and comfort.

[0091] In actual applications, in order to meet the special requirements of sportswear, an appropriate yarn type can be selected based on the positioning of the product and the characteristics of the target market.

[0092] [Fabric product] The fabric product according to the second aspect of the present invention includes the above-mentioned fabric.

[0093] Examples of the fabric product include, for example, clothes (specifically, sportswear such as tracksuits, shorts, T-shirts, polo shirts, swimsuits, wet suits, ski suits, leotards, training shoes, soccer shoes, riding boots, ice skating shoes, etc. and outdoor wear), bedding covers, sheets, futons, padding pads, pillows, rugs, cushions, sofa covers, towels, curtains, hats, scarves, shoe sole sheets, socks, headbands, chair seats, chair covers, etc.

[0094] The fabric product has the advantageous effects of the above-mentioned fabric.

[0095] As described above, each component of the present invention and their combinations, etc. are examples, and additions, omissions, substitutions, and changes to the components can be made as appropriate without departing from the gist of the present invention. Further, the present invention is not limited by the embodiments, but is limited only by the description in the scope of claims for utility model registration.

Example

[0096] Hereinafter, the present invention will be described more specifically by way of examples, but the present invention is not limited by these examples.

[0097] When the fiber yarns in the following examples contain ceramic powder in the sheath layer, the ceramic powder content in the sheath layer of the fiber yarns in each example is the same. Also, when the fiber yarns in the following examples contain ceramic powder in the core layer, the ceramic powder content in the core layer of the fiber yarns in each example is the same.

[0098] Example 1 A polyester fiber yarn comprising a core layer and a sheath layer, wherein the sheath layer contains a ceramic powder, a part of the ceramic powder is exposed on the surface of the sheath layer to form a diffuse reflection part, and a polyester fiber yarn containing no ceramic powder is used for the core layer to form a first functional layer. Also, a T400 yarn was used to form a second functional layer. Then, the first functional layer and the second functional layer were connected by a method of mixing and weaving them with each other to obtain a fabric (fabric area: 10 cm 2 ).

[0099] Example 2 As the fiber yarn for forming the first functional layer, a polyester fiber yarn comprising a core layer and a sheath layer was used, wherein the sheath layer and the core layer contain a ceramic powder, and a part of the ceramic powder contained in the sheath layer is exposed on the surface of the sheath layer to form a diffuse reflection part. A fabric was obtained in the same manner as in Example 1 except for this.

[0100] Example 3 As the fiber yarn for forming the first functional layer, a polyester fiber yarn containing a ceramic powder in the sheath layer and the core layer, and a part of the ceramic powder contained in the sheath layer is exposed on the surface of the sheath layer to form a diffuse reflection part was used. A fabric was obtained in the same manner as in Example 1 except that cotton yarn was used as the fiber yarn for forming the second functional layer.

[0101] Example 4 As the fiber yarn for forming the first functional layer, a polyester fiber yarn containing a ceramic powder in the sheath layer and the core layer, and a part of the ceramic powder contained in the sheath layer is exposed on the surface of the sheath layer to form a diffuse reflection part was used. A fabric was obtained in the same manner as in Example 1 except that nylon yarn was used as the fiber yarn for forming the second functional layer.

[0102] Comparative Example 1 As the fiber yarn for forming the first functional layer, a fabric was obtained in the same manner as in Example 1 except that a polyester fiber yarn containing no ceramic powder and having no diffuse reflection part in the sheath layer was used.

[0103] For the fabrics obtained in the above examples and comparative examples, the ability to hide sweat marks, quick-drying property, ultraviolet ray protection ability, near-infrared ray protection ability, heat insulation property, air permeability, and contact cool feeling were evaluated by the following tests. The results are shown in Table 1.

[0104] Test for the ability to hide sweat marks: The fabric was spread flat on an embossed circular bracket, and the time (seconds) for the water to disappear after dripping onto the fabric was measured.

[0105] Quick-drying property test: According to the method specified in "ISO17617-2014 Textiles - Determination of the drying rate of moisture", the time (minutes) until the fabric was completely dried was measured.

[0106] Ultraviolet ray protection ability test: Using a spectrophotometer, the ultraviolet transmittance at wavelengths of 280 - 400 nm was measured, and the ultraviolet shielding rate (%) was obtained by calculation.

[0107] Near-infrared ray protection ability test: Using a spectrophotometer, the near-infrared transmittance (%) at wavelengths of 780 - 2500 nm was measured.

[0108] Heat insulation property test: Based on "JIS L1951 Test method for heat insulation property of fabrics", using a thermosensitive imager and a thermocouple temperature sensor, the temperature change of the heat energy after the heat source (or light source) passed through the sample was measured, and the heat insulation rate (%) was obtained by calculation.

[0109] Air permeability test: Based on GB / T5453-1997 "Determination of air permeability of textiles", the air permeability rate (mm / s) of the fabric was measured.

[0110] Contact cool feeling test: Based on JIS L1927 "Test method for contact cool feeling of textiles", the maximum heat absorption rate q-max (W / cm 2 ) of the fabric was obtained.

Table 1

[0112] As can be seen from Table 1, the fabric of the present invention has the ability to hide sweat marks, ultraviolet ray protection ability, and near-infrared ray protection ability, which are better than those of Comparative Example 1. Since Example 2 has better ability to hide sweat marks, ultraviolet ray protection ability and near-infrared ray protection ability than Example 1, it can be seen that using functional fibers containing ceramic powder in both the sheath layer and the core layer is effective in achieving the above performance. Since Example 3 has better air permeability than Example 2, it can be seen that selecting cotton yarn as the second yarn constituting the second functional layer is effective in improving air permeability. Since Example 4 has better contact cooling sensation than Example 2, it can be seen that selecting nylon yarn as the second yarn constituting the second functional layer is effective in improving contact cooling sensation.

[0113] The fabric of the present invention is a multifunctional fabric and can have one or more of the performances of the ability to hide sweat marks, ultraviolet ray protection ability, near-infrared ray protection ability, quick drying property, air permeability, and contact cooling sensation.
