Abstract
Description
Technical Field
[0001] The present application relates to the field of textile fabrics, and mainly to a light, thin and light-proof fabric. Background Art
[0002] With the development of society and economy, people's pursuit of clothing is not only limited to the design of style, but also pays more attention to the comfort and functionality of wearing. Although clothing with various colors is popular among people, with the change of wearing concepts and the diversification of clothing, people's demand for white clothing is getting higher and higher, especially the fabrics made of undyed warp yarn and white weft yarn interwoven to highlight the beautiful effect of wearing.
[0003] White clothing may cause the embarrassing problem of color exposure during wearing. For example, many women like to wear white clothing, especially white pants. Since white is light-transmissive, the color of the core layer of underwear is more likely to show up, so anti-light-transmitting white fabrics are needed.
[0004] In the prior art, researchers usually use thick yarns for weaving and increase the warp and weft density of the fabric, so that the fabric has a certain degree of thickness, which can block direct sunlight to a certain extent and reduce the problem of light transmission of white fabrics, but this cannot meet people's needs in hot summer. In hot summer, if people wear dark-colored clothes, they will absorb sunlight and generate heat, making people feel stuffy during wearing. Therefore, light-colored or white clothes will be more popular in hot summer because they can reflect a certain amount of sunlight. However, using thick yarns for weaving and increasing the warp and weft density of the fabric to only make thick and tight white clothes cannot meet the demand for cool feeling when wearing in summer.
[0005] Therefore, the prior art still needs to be improved and developed. Utility Model Content
[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a thin and light-proof fabric, aiming to solve the problem that the existing white fabric cannot be both thin and light-proof at the same time.
[0007] The technical solution of this application is as follows:
[0008] A thin and light-proof fabric, comprising a base fabric layer and a hydrophilic layer, wherein the hydrophilic layer is arranged on the bottom surface of the base fabric layer;
[0009] The base fabric layer includes warp yarns and weft yarns interwoven with each other, and the weft yarns include first weft yarns and second weft yarns;
[0010] The first weft yarn is a yarn with a core-skin structure, the core layer is polyester, and the skin layer is nylon; silicon dioxide particles are arranged in the polyester, and protrusions are arranged on the outer surface of the nylon;
[0011] The second weft yarn is honeycomb polyester;
[0012] The warp yarn is pure cotton yarn;
[0013] In the minimum weave cycle diagram formed by interweaving the warp yarns and the weft yarns, the number of weft weave points on the bottom surface of the base fabric layer is 3-4 times the number of warp weave points.
[0014] The light and anti-light-transmitting fabric of the present application is suitable for preparing white clothing, so that the white clothing is not only light and comfortable to wear but also can quickly absorb moisture and perspiration, so that people can wear cool and comfortable in summer, and also has a good anti-light-transmitting effect.
[0015] In the thin and light-proof fabric, the cross-sectional area of the core layer is 4-9 times the cross-sectional area of the skin layer, so that the light-proof effect can be better.
[0016] The thin and light-proof fabric, wherein the diameter of the first weft yarn is 1.2-1.5 times the diameter of the second weft yarn.
[0017] The thin and light-proof fabric, wherein the hydrophilic layer is one of a polysiloxane hydrophilic layer, a polyurethane hydrophilic layer, a soluble polyurethane hydrophilic layer or a modified silicone emulsion hydrophilic layer.
[0018] The thin and light-proof fabric, wherein the yarn count of the warp yarn ranges from 8 to 60S.
[0019] The thin and light-proof fabric, wherein the D number of the first weft yarn is 40-100D.
[0020] The thin and light-proof fabric, wherein the D number of the second weft yarn is 150-500D.

[0022] The thin and light-proof fabric has a gram weight of 5-7OZ.
[0023] Beneficial effect: The thin and light-proof fabric of the present application is suitable for preparing white clothing, which makes the white clothing not only thin and comfortable to wear but also able to quickly absorb moisture and perspiration, making people cool and comfortable to wear in summer, but also has good light-proof effect and is not prone to the embarrassing problem of color exposure.

[0028] The present application provides a thin and light-proof fabric. To make the purpose, technical solution and effect of the present application clearer and more specific, the present application is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.
[0029] In the prior art, in order to make white fabrics achieve the effect of anti-light transmission, researchers usually use thick yarns for weaving and increase the warp and weft density of the fabric, thereby increasing the thickness of the white fabric to achieve the anti-light transmission effect. However, the thick white fabric will make people feel stuffy when wearing it in the hot summer, and cannot meet people's needs in the hot summer. Therefore, it is necessary to study a thin and light-proof fabric suitable for preparing white clothing, so that the white clothing is not only light and comfortable to wear, but also can quickly absorb moisture and perspiration, so that people can wear it cool and comfortable in summer, but also has a good anti-light transmission effect, and is not prone to the embarrassing problem of color exposure.
[0030] Specifically, the present application provides a thin and light-proof fabric, such as Figure 1-Figure 3 As shown, it includes a base fabric layer 1 and a hydrophilic layer 2, and the hydrophilic layer 2 is arranged on the bottom surface of the base fabric layer 1;
[0031] The base fabric layer 1 comprises warp yarns 10 and weft yarns interwoven with each other, wherein the weft yarns comprise first weft yarns 21 and second weft yarns 22;
[0032] The first weft yarn 21 is a yarn with a core-skin structure, the core layer 211 is polyester, the skin layer 212 is nylon, and the cross-sectional area of the core layer 211 is 4-9 times the cross-sectional area of the skin layer 212; silica particles are arranged in the polyester, and protrusions are arranged on the outer surface of the nylon;
[0033] The second weft yarn 22 is honeycomb polyester; the warp yarn 10 is pure cotton yarn;
[0034] In the minimum weave cycle diagram formed by interweaving the warp yarn 10 and the weft yarn, the number of weft weave points on the bottom surface of the base fabric layer 1 is 3-4 times the number of warp weave points.
[0035] When the human body is exercising or moving, the sweat generated is in direct contact with the thin and light-proof fabric of the present application. The hydrophilic layer 2 located on the bottom surface of the base fabric layer 1 is in direct contact with the human body, and can absorb a large amount of sweat, so that the sweat can be quickly adsorbed, and then the sweat comes to the bottom surface of the base fabric layer 1 through the hydrophilic layer 2; in the base fabric layer 1, the outer surface of the nylon layer 212 of the first weft yarn 21 is provided with protrusions, which can quickly conduct moisture; the second weft yarn 22 is honeycomb polyester, which has a porous structure and good hygroscopicity. It can effectively absorb sweat in summer and also play a role in moisture conduction. At the same time, combined with the capillary effect formed by the fabric, the sweat can be quickly transferred from the bottom surface of the base fabric layer 1 to the surface of the base fabric layer 1. Since the warp yarn 10 is pure cotton yarn, it also has good hygroscopicity, so that the sweat can be quickly spread on the surface of the base fabric layer 1. In the external environment, the sweat can evaporate quickly to achieve a dry effect. In addition, since the skin layer 212 of the first weft yarn 21 is nylon, the thin and light-proof fabric of the present application can also bring a cooling effect when it comes into contact with the skin.
[0036] The thin and light-proof fabric of the present application has a yarn count range of 8~60S for the warp yarn 10, a D number of 40~100D for the first weft yarn 21, a D number of 150~500D for the second weft yarn 22, a warp density of 50~100 strands / inch, a weft density of 50~100 strands / inch, and a gram weight of the fabric of 5-7OZ.
[0037] In the thin and light-proof fabric of the present application, the cross-sectional area of the core layer 211 of the first weft yarn 21 is 4-9 times the cross-sectional area of the skin layer 212, so that the core layer 211 polyester accounts for more than the skin layer 212 nylon, and there is more space to set silica particles. These silica particles can refract and reflect light under the irradiation of sunlight to achieve the effect of light-proof. The weight of the silica particles can account for 10-20% of the total weight of polyester, and the first weft yarn 21 with this ratio can achieve a better light-proof effect. The preparation process of the yarn with skin-core structure is prior art and will not be repeated here.
[0038] Preferably, the diameter of the first weft yarn 21 is 1.2-1.5 times the diameter of the second weft yarn 22. In the present application, the second weft yarn 22 is thinner than the first weft yarn 21, so that the second weft yarn 22 is covered by the first weft yarn 21, which can increase the effect of reflecting light to a certain extent.
[0039] When the sun shines, when the sun shines through the surface of the base fabric layer 1 and enters the bottom surface, since the second weft yarn 22 is thinner than the first weft yarn 21, the second weft yarn 22 will be covered by the first weft yarn 21 during the weaving process, and the second weft yarn 22 will generally be located in the middle of the base fabric layer 1, which can refract and reflect the light to a certain extent, further reducing the intensity of the light. When the light further shines and reaches the first weft yarn 21, the raised part of the nylon of the skin layer 212 of the first weft yarn 21 can reflect the light to a certain extent, and at the same time, combined with the silica particles of the polyester of the core layer 211, a large amount of light is refracted and reflected, thereby achieving an anti-light transmission effect. The transmittance of the thin and anti-light transmission fabric of the present application within the visible light wavelength (VS) is tested on a computer colorimeter. The lower the transmittance, the better the anti-light transmission property of the fabric. After testing, the light and thin anti-light fabric of the present application is compared with the fabric of the same specification of the first weft yarn 21 core layer 211 polyester without silica particles. The transmittance of the light and thin anti-light fabric of the present application is reduced by more than 90%, which proves that the light and thin anti-light fabric of the present application has a better anti-light effect.
[0040] Preferably, the hydrophilic layer 2 can be one of a polysiloxane hydrophilic layer 2, a polyurethane hydrophilic layer 2, a soluble polyurethane hydrophilic layer 2 or a modified silicone emulsion hydrophilic layer 2. By providing the hydrophilic layer 2 on the bottom surface of the base fabric layer 1, it can be in direct contact with the human body, can absorb a large amount of sweat, and can quickly absorb the sweat.
[0041] The present application is further described below by way of examples.
[0042] Example
[0043] The warp yarn 10 is made of 8S pure cotton yarn, the second weft yarn 22 is made of 75D honeycomb polyester, the first weft yarn 21 is 300D filament, the core layer 211 of the first weft yarn 21 is polyester provided with silica particles, the skin layer 212 of the first weft yarn 21 is nylon, the cross-sectional area of the core layer 211 is 4 times the cross-sectional area of the skin layer 212, the first weft yarn 21 and the second weft yarn 22 are woven in a 1:1 ratio, the fabric structure is 3 / 1, and the warp and weft density of the fabric is 85x68 roots / inch.
[0044] Fabric anti-light transmission test: Under the D65 light source, first measure the color value of the reference color white cloth (Lw) and the color value of the reference color black cloth (Lb); then put the test sample on the reference color white cloth and measure its color value (Lfw), and then put the test sample on the reference color black cloth and measure its color value (Lfb). Anti-light transmission rate = (1-(Lfw-Lfb) / (Lw-Lb))×100%.
[0045] Through testing, the light-proof rate of the thin and light-proof fabric of the embodiment of the present application is 93.8%.

For ordinary technicians in this field, improvements or changes can be made according to the above description, and all these improvements and changes should fall within the scope of protection of the present application.
