[0014] On the other hand, the present application provides a textile including the above-mentioned fabric.

[0015] The present application provides a fabric and a textile. The fabric includes a first functional layer and a second functional layer. The first yarn of the first functional layer is composed of functional fibers. The sheath surface of the functional fibers includes a plurality of diffuse reflection portions, which can reduce specular reflection on the fabric surface, thereby facilitating the hiding of sweat stains on the fabric. The second functional layer is formed by a second yarn having at least one of a quick-drying function, a breathable function, and a cooling function, so that the fabric provided by the present application not only has the function of hiding sweat stains, but also can have a quick-drying function, a breathable function, and a cooling function.

These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0027] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0028] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0029] The generation of sweat marks mainly stems from two aspects. On the one hand, when sweat stays on the fabric surface, due to the optical properties of the fabric material, specular reflection will occur under light irradiation, resulting in some areas of the clothing looking darker or shinier, thus forming visible sweat marks. On the other hand, if the moisture absorption and diffusion ability of the fabric is insufficient, the sweat cannot be effectively absorbed and quickly diffused, but will accumulate locally, further exacerbating the formation of sweat marks, especially obvious in the case of high - intensity or long - duration exercise. In the related art, the surface of the fabric yarn is relatively smooth, making it easy for sweat marks to undergo specular reflection on the fabric, making the sweat marks visible.

[0030] The fabric and textile provided by the present application aim to solve the above - mentioned technical problems in the prior art.

[0031] The following will use specific embodiments to detail the technical solutions of the present application and how the technical solutions of the present application solve the above - mentioned technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application in conjunction with the drawings.

[0032] Please refer toFigures 1 to 4 , the fabric provided by the embodiment of the present application includes a first functional layer 100 and a second functional layer 200. The first functional layer 100 is disposed on one side of the second functional layer 200. The first functional layer 100 is formed by first yarns 110. The first yarns 110 include functional fibers 10. The functional fibers 10 include a core layer 11 and a sheath layer 12. The sheath layer 12 is disposed on the outer periphery of the core layer 11, and the surface of the sheath layer 12 includes a plurality of diffuse reflection portions 13. The second functional layer 200 is formed by second yarns 210. The second yarns 210 have at least one of a quick-drying function, a breathable function, and a cool feeling function.

[0033] In this embodiment, the first yarns 110 are formed by multiple functional fibers 10. The functional fibers 10 include a core layer 11 and a sheath layer 12. The sheath layer 12 is disposed on the outer periphery of the core layer 11. The sheath layer 12 plays a protective role for the core layer 11, reducing the influence of the external environment, such as abrasion and erosion. Please refer to Figure 3 and Figure 4 , diffuse reflection portions 13 are provided on the surface of the sheath layer 12. The diffuse reflection portions 13 cause the light reaching the fabric to undergo diffuse reflection, reducing the specular reflection of light on the fabric. In this way, when the fabric absorbs sweat or sweat accumulates on the fabric, it is convenient to hide the sweat stains and reduce the appearance of sweat patches. Therefore, the functional layer formed by the first yarns 110 has the function of hiding sweat stains, which is beneficial for the wearer to maintain a neat appearance when sweating.

[0034] Exemplarily, the diffuse reflection portions 13 are pits, grooves or protrusions. Or, the functional fibers 10 have a special-shaped cross-section, such as a flat shape, a triangular shape or other irregular shapes. Compared with circular cross-section fibers, this special-shaped cross-section fiber increases the scattering ability of light on the surface of the yarn.

[0035] The second functional layer 200 has at least one of a quick-drying function, a breathable function, and a cool feeling function, so that the fabric provided by the embodiment of the present application can also have a quick-drying function, a breathable function and a cool feeling function on the basis of having the function of hiding sweat stains, thereby improving the versatility and practicality of the fabric. It can be understood that the second yarns 210 can simultaneously have one or several of the quick-drying function, the breathable function or the cool feeling function.

[0036] Exemplarily, the second functional layer 200 has a sweat-absorbing and quick-drying function, which can accelerate the absorption of sweat by the fabric and quickly evaporate on the surface of the quick-drying layer, achieving the effect of quick drying. Among them, the second yarns 210 of the second functional layer 200 can be fiber materials, so that the second functional layer 200 formed by the second yarns 210 has the ability of moisture absorption and quick drying. The fiber material itself has many micropores and channels, and the micropores and channels are similar to capillaries, which can promote the diffusion of moisture along the axial and radial directions of the fiber, thereby being beneficial to improving the moisture absorption and quick-drying performance of the yarn.

[0037] In addition, the second yarn 210 can be made of materials such as cotton, linen, bamboo fiber, synthetic fiber, etc. Among them, the synthetic fiber can be polyester fiber, nylon fiber. The second yarn 210 made of the above materials has good air permeability and moisture absorption, so that the second functional layer 200 has an air permeable function.

[0038] The second yarn 210 is made of materials such as polyester fiber, viscose fiber, polyamide fiber, modal fiber, polylactic acid fiber, etc. The second yarn 210 made of the above materials has good thermal conductivity and fast moisture absorption and drying properties, thus bringing a cool touch to the wearer and making the second functional layer 200 have a cool feeling function.

[0039] Furthermore, when the second functional layer 200 is a functional layer with a quick-drying function, the second functional layer 200 is located on the side of the first functional layer 100 facing the skin. When the human body sweats a lot, the second yarn 210 in the second functional layer 200 absorbs the sweat produced by the human skin and transfers the sweat to the functional layer. The air contacts the functional layer and takes away the sweat absorbed on the functional layer, achieving rapid drying and making the sweat absorption and air permeability effect good; at the same time, since the sheath layer 12 of the functional layer is provided with a diffuse reflection part 13, it is convenient to hide the sweat marks, thereby improving the cleanliness of the clothing.

[0040] Therefore, in the embodiment of the present application, the first functional layer 100 reduces the specular reflection on the surface of the fabric, making it convenient to hide the sweat marks; through the second functional layer 200, the fabric can also have quick-drying, air permeable and cool feeling functions.

[0041] In an alternative embodiment, the sheath layer 12 and the core layer 11 include ceramic powder 101, and the diffuse reflection part 13 includes ceramic powder 101.

[0042] The functional fiber 10 has a core-sheath structure, and the sheath layer 12 surrounds the outer side of the core layer 11. The sheath layer 12 and the diffuse reflection part 13 of the sheath layer 12 contain ceramic powder 101. On the one hand, the sheath layer 12 contains ceramic powder 101, which increases the surface roughness of the sheath layer 12. Due to the increased surface roughness of the sheath layer 12 and the presence of multiple diffuse reflection parts 13 on the surface of the sheath layer 12, it is beneficial for light to undergo diffuse reflection in the first functional layer 100. On the other hand, since there is ceramic powder 101 on the surface of the sheath layer 12, multiple tiny diffuse reflection parts 13 can be formed on the surface of the sheath layer 12, thereby increasing the surface roughness of the sheath layer 12 so that light can undergo diffuse reflection in the sheath layer 12. In addition, the sheath layer 12 and the diffuse reflection part 13 of the sheath layer 12 contain ceramic powder 101, making the functional fiber 10 form more micropores and channels. When light irradiates the first functional layer 100, a part of the external light undergoes diffuse reflection in the sheath layer 12, and the other part enters the micropores of the functional fiber 10. During this process, the ultraviolet rays and near-infrared rays that enter the micropores are continuously reflected in the micropores, facilitating the absorption of ultraviolet rays and near-infrared rays by the ceramic powder 101, and thus being beneficial for further improving the heat shielding ability and protection ability of the fabric.

[0043] Therefore, the fabric provided by the embodiment of the present application can improve the ultraviolet protection ability, the ability to resist near-infrared rays, and the ability to hide sweat stains.

[0044] Exemplarily, the ceramic powder 101 is titanium oxide, zinc oxide or silicon dioxide. Among them, titanium oxide can absorb ultraviolet radiation, reduce the penetration of ultraviolet rays into the fiber interior or reach the skin, thereby enhancing the ultraviolet protection function of the first yarn 110 and its products.

[0045] Furthermore, in an optional embodiment, the core layer 11 includes ceramic powder 101, and the content of ceramic powder 101 in the core layer 11 is greater than or equal to the content of ceramic powder 101 in the sheath layer 12.

[0046] Both the sheath layer 12 and the core layer 11 of the functional fiber 10 contain ceramic powder 101, making more micropores and channels formed in the functional fiber 10. The micropores and channels are similar to capillaries and can promote the diffusion of moisture along the axial and radial directions of the fiber, thus being beneficial for improving the moisture absorption and quick-drying performance of the yarn. When ultraviolet rays and near-infrared rays irradiate the functional fiber 10, the ceramic powder 101 in the core layer 11 can absorb and scatter part of the ultraviolet rays and infrared rays, thus being beneficial for improving the ultraviolet protection ability and heat shielding performance of the fabric. Moreover, since the yarn is made of fiber material, the ceramic powder 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 thus be beneficial for improving the wear resistance and tensile properties of the first functional layer 100.

[0047] Meanwhile, since the light entering the sheath layer 12 can also undergo diffuse reflection in the core layer 11, it becomes more difficult for sweat stains on the fabric to become visible, thereby further reducing the formation of obvious wet marks by sweat on the surface of the clothing, further improving the neatness of the wearer's clothing, and reducing the psychological discomfort caused by sweat stains.

[0048] As mentioned above, the ceramic powder 101 can increase the strength and rigidity of the functional fiber 10. However, excessive ceramic powder 101 may affect the softness and elasticity of the yarn, thereby increasing the hardness and roughness of the yarn, which is instead unfavorable for wearing comfort. Therefore, the content of the ceramic powder 101 in the core layer 11 is greater than or equal to the content of the ceramic powder 101 in the sheath layer 12, which can enable the yarn to have good toughness and rigidity, while endowing the yarn with a certain heat shielding ability and ultraviolet radiation resistance. Moreover, due to the lower content of the ceramic powder 101 in the sheath layer 12, the sheath layer 12 can maintain a certain softness, preventing the surface of the yarn from being overly rough due to excessive ceramic powder 101 particles, thus affecting the touch, gloss, etc. of the fabric. In this way, it is also convenient for subsequent processing of the yarn (such as dyeing).

[0049] For the fabric provided by the embodiment of the present application, by controlling the content of the ceramic powder 101 in the core layer 11 to be greater than or equal to the content of the ceramic powder 101 in the sheath layer 12, the fabric not only has good heat shielding ability and ultraviolet radiation resistance, but also ensures that the yarn has a certain softness and processability.

[0050] In an optional embodiment, the diffuse reflection part 13 is in a convex shape or a concave shape, and a plurality of diffuse reflection parts 13 are arranged at intervals on the surface of the sheath layer 12.

[0051] The convex-shaped or concave-shaped diffuse reflection part 13 causes light to scatter in multiple directions, reducing the specular reflection of the yarn and its products, thereby facilitating the hiding of sweat stains and improving the neatness of the clothing. Optionally, the convex shape and the concave shape are circular, square, diamond-shaped, oval, trapezoidal or other shapes.

[0052] Please refer to Figure 2 , in an optional embodiment, the first functional layer 100 and the second functional layer 200 are connected by a connecting line 300, ensuring that the two layers of fabric can be firmly connected together while not affecting the overall performance of the fabric. In this embodiment, no specific limitation is imposed on the connecting line 300, as long as it can connect the second functional layer 200 and the first functional layer 100, and the connecting line 300 can be different types of yarns.

[0053] In an optional embodiment, the first functional layer 100 and the second functional layer 200 can be connected together by an interlaced manner. That is to say, the connecting line 300 can be the first yarn 110 or the second yarn 210.

[0054] Connecting the first functional layer 100 and the second functional layer 200 through the second yarn 210 or the first yarn 110 is beneficial to ensure the transfer of sweat from the second functional layer 200 to the first functional layer 100, thereby improving the sweat absorption and quick-drying performance. To further improve the structural compactness, the connecting line 300 is the second yarn 210 of the second functional layer 200 or the first yarn 110 of the first functional layer 100. During the process of knitting the second functional layer 200 and the first functional layer 100, the second functional layer 200 and the first functional layer 100 are knitted together through the second yarn 210 and the first yarn 110 respectively, while connecting the first functional layer 100 and the second functional layer 200, without the need for an additional connecting line 300 or sewing process, avoiding subsequent sewing or bonding steps. In this way, the fabric becomes smoother, reducing friction and irritation, which is beneficial to improving the wearing comfort, simplifying the production process, reducing costs, and also reducing material waste.

[0055] In an alternative embodiment, the first functional layer 100 is a plain weave structure, a mesh structure, a stripe structure, or a checkerboard structure, and the second functional layer 200 is a plain weave structure, a mesh structure, a stripe structure, or a checkerboard structure.

[0056] The structure of the fabric is a knitting structure of yarns. Among them, the plain weave structure can enhance the tightness and durability of the fabric while maintaining good breathability and quick-drying performance. The mesh structure can effectively increase the breathability and ventilation of the fabric, helping to quickly evaporate sweat, and is suitable for sports clothing. The stripe structure is formed by the arrangement of yarns into stripes, which can be horizontal, vertical, or diagonal, and the density of the yarns can adjust the breathability and warmth retention of the fabric. The checkerboard structure is similar to the mesh structure, which can also improve the breathability and quick-drying property of the fabric, while also giving the fabric a certain elasticity and stretchability.

[0057] Therefore, through the above structure, the fabric of the embodiment of the present application can effectively combine the functions of hiding sweat marks and quick drying, providing a better sports experience and comfort. It can be understood that the fabric of the embodiment of the present application can be customized according to specific application scenarios and the needs of target users. For example, for summer sports clothing, the first functional layer 100 and the second functional layer 200 with a mesh structure or a checkerboard structure can be selected to enhance breathability and quick-drying performance; while for sports equipment in spring and autumn, a stripe structure or a plain weave structure can be selected to balance warmth retention and breathability.

[0058] In an alternative embodiment, the second yarn 210 is a cotton yarn, a bamboo fiber yarn, a T400 yarn, a T8 yarn, a PBT yarn, a PTT yarn, a nylon yarn, a polyester yarn, a polypropylene yarn, or a polyethylene yarn.

[0059] It should be noted that polypropylene yarn is a lightweight, strong and chemically resistant synthetic fiber with extremely low water absorption, suitable for making quick-drying fabrics. T400 yarn is a polyester elastic fiber that combines the durability of polyester and the extensibility of elastic fiber, with the advantages of quick drying and not easily deforming, suitable for making sports underwear, leggings and other sports clothing that requires a certain degree of elasticity. PTT yarn is an environmentally friendly polyester fiber with a soft handfeel and good dyeing performance, and at the same time has excellent elastic recovery and wrinkle resistance. T8 yarn is a polyester fiber with high strength and good elasticity, with a fast drying speed and excellent wear resistance, suitable for making sports clothing that needs to withstand high-intensity exercise, such as running clothes and training clothes. PBT yarn is a polyester fiber with good elasticity and recovery, while maintaining good quick-drying performance. Ethylene yarn, also known as polyethylene yarn, is an extremely lightweight and strong fiber with a very low water absorption rate, so it can dry quickly, suitable for making outdoor equipment and sports clothing that require extremely high durability and quick-drying properties.

[0060] It can be understood that in practical applications, the appropriate type of yarn can be selected according to the specific product positioning and the characteristics of the target market to meet the specific needs of sports clothing.

[0061] In an alternative embodiment, the thickness of the first functional layer 100 is 0.01 - 1 mm. Setting the thickness of the first functional layer 100 of the fabric within the above range helps to enhance the structural stability and durability of the fabric, as well as having good air permeability and comfort.

[0062] Exemplarily, the thickness of the first functional layer 100 includes but is not limited to 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, 1 mm.

[0063] In an alternative embodiment, the thickness of the second functional layer 200 is 0.01 - 1 mm. Setting the thickness of the second functional layer 200 of the fabric within the above range is beneficial to improving air permeability and flexibility, and accelerating the diffusion and evaporation rate of moisture.

[0064] Exemplarily, the thickness of the second functional layer 200 includes but is not limited to 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, 1 mm.

[0065] In some alternative embodiments, the first yarn 110 is made by using filament yarn or staple fiber yarn as the basic raw material.

[0066] Exemplarily, when the first yarn 110 is a filament yarn, the fineness of the filament yarn is 10 - 150 D. By adjusting the fineness difference between the first yarn 110 and the second yarn 210, it is beneficial to increase the pressure difference between the first functional layer 100 and the second functional layer 200, thereby improving the sweat export speed. When the first yarn 110 is a staple fiber yarn, the fineness of the staple fiber yarn is 10 - 50 s. A smaller fineness of the staple fiber yarn (such as 50 s) means finer fibers, which helps to increase the porosity of the fabric, thereby improving the sweat diffusion speed. Compared with the filament yarn, the single fiber length of the staple fiber yarn is shorter, but its larger specific surface area helps to improve the sweat adsorption and export speed.

[0067] Specifically, the fineness of the filament yarn is 5 - 150 D, such as 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, 150 D or the range composed of any two of them. The fineness of the staple fiber yarn is 10 - 50 s, such as 10 s, 20 s, 30 s, 40 s, 50 s or the range composed of any two of them.

[0068] It should be noted that fineness is an index to measure the thickness of yarns or fibers. It reflects the diameter size of yarns or fibers and has an important impact on the quality and properties of textiles. The main units of fineness include Denier (D) and yarn count (S). Denier is a fineness unit mainly used to represent the fineness of synthetic fibers, artificial fibers and some natural fibers. 1 Denier is defined as the weight of 9000 meters of fiber being 1 gram. That is to say, the higher the Denier value, the coarser the fiber. Yarn count is mainly used for cotton yarns. 1 yarn count is defined as the length of 1 pound of fiber at the standard regain. The larger the yarn count, the finer the yarn.

[0069] The embodiment of the present application also provides a textile including the above-mentioned fabric. It can be understood that this textile has the beneficial effects of the above-mentioned fabric, so they will not be elaborated here one by one.

[0070] The following further illustrates the present invention through specific embodiments. It should be noted that the following embodiments are all fabrics made of yarns, the fabric area is 10 square centimeters; the first functional layer and the second functional layer are connected in an interwoven manner; when the sheath layer of the fiber of the yarn in each of the following embodiments contains ceramic powder, the sheath layer ceramic powder content in each embodiment is the same; when the core layer of the fiber of the yarn in each of the following embodiments contains ceramic powder, the core layer ceramic powder content in each embodiment is the same.
