Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to an anti-ultraviolet fabric. Background Art

[0002] With the popularity of light outdoor sports, light outdoor sportswear has also become a new popular trend, prompting the outdoor leisure clothing product market to flourish. People's requirements for the comfort and functionality of light outdoor sportswear are gradually increasing, among which breathability and UV protection functions are particularly important.

[0003] In some prior arts, in order to improve the anti-ultraviolet performance of fabrics, an anti-ultraviolet layer is added to the fabric, and the anti-ultraviolet layer is usually formed by materials such as anti-ultraviolet coatings and anti-ultraviolet yarns. For example, the patent document with the publication number CN216659188U discloses an anti-ultraviolet polyester fabric, which includes a base layer, a black cotton yarn layer is provided on the upper surface of the base layer, and an anti-ultraviolet coating layer is provided on the side away from the base layer, and an elastic cotton layer is provided on the lower surface of the base layer, and a plurality of air holes are provided in the elastic cotton layer, and a fine cotton layer is provided on the side away from the base layer. The anti-ultraviolet layer formed by the anti-ultraviolet seasoning is thin, and the fabric is relatively light, but the anti-ultraviolet layer will gradually lose its function with washing. In order to obtain a higher ultraviolet absorption rate, the anti-ultraviolet layer formed by the anti-ultraviolet yarn needs to increase the thickness and density of the anti-ultraviolet layer, which makes the fabric thick and heavy, and reduces the lightness and breathability, affecting the comfort of use, and is not suitable for light outdoor sportswear. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an anti-ultraviolet fabric, which has good anti-ultraviolet ability, a relatively light fabric structure, and a long anti-ultraviolet life, and is suitable for light outdoor sportswear.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A UV-resistant fabric comprises a skin-friendly base layer, a wear-resistant base layer and an UV-resistant woven layer arranged between the skin-friendly base layer and the wear-resistant base layer; the UV-resistant woven layer is formed by repeatedly connecting a plurality of oblique corrugations protruding toward the wear-resistant base layer, each of the oblique corrugations comprising a first oblique side and a second oblique side connected at an angle; on a side close to the wear-resistant base layer, the first oblique side and the second oblique side located on the same oblique corrugation are integrally connected, and the oblique corrugations form a first adhesive connection portion connected to the wear-resistant base layer; on a side close to the skin-friendly base layer, the first oblique side and the second oblique side located on the same oblique corrugation are separated from each other, and the oblique corrugations form a second adhesive connection portion and a third adhesive connection portion connected to the skin-friendly base layer; in the same oblique corrugation, the projection position of the first adhesive connection portion on the skin-friendly base layer does not fall between the second adhesive connection portion and the third adhesive connection portion, and the first adhesive connection portion is located on a side relatively close to the second adhesive connection portion; in two adjacent oblique corrugations, the second adhesive connection portion of one oblique corrugation is integrally connected to the third adhesive connection portion of the other oblique corrugation.

[0007] In the utility model, the anti-ultraviolet textile layer has a nearly wavy structure, and each oblique corrugation constitutes a wave crest. The top of the wave crest forms a first bonding portion and is connected to the inner side of the wear-resistant base layer. The two sides of the wave crest away from the top respectively form a second bonding portion and a third bonding portion and are connected to the inner side of the skin-friendly base layer. The projection position of the first bonding portion on the skin-friendly base layer does not fall between the second bonding portion and the third bonding portion, and the first bonding portion is located on a side relatively close to the first bonding portion, so that the wave crest obliquely protrudes toward one side of the first bonding portion and passes over the first bonding portion. When several oblique corrugations are connected, the first oblique corrugation partially covers the first bonding portion. The first oblique wrinkle is partially covered by the third oblique wrinkle located on the side of the second adhesive part. When ultraviolet rays enter the fabric perpendicularly, due to the layered covering structure between the oblique wrinkles, ultraviolet rays need to pass through the anti-ultraviolet textile layer multiple times to reach the skin-friendly base layer, which greatly improves the equivalent thickness of the anti-ultraviolet textile layer. In addition, ultraviolet rays will undergo a large amount of refraction and scattering during the process of passing through the anti-ultraviolet textile line multiple times. On the one hand, the anti-ultraviolet performance is enhanced, and on the other hand, the textile thickness and textile density of the anti-ultraviolet textile layer body can be reduced, making it easier for air to penetrate the anti-ultraviolet textile layer, solving the problem of the existing anti-ultraviolet fabric being heavy and stuffy. In addition, the wavy structure of the anti-ultraviolet textile layer of the utility model can also be extended to a large extent when subjected to tension, so that the fabric has good tensile elasticity.

[0008] Furthermore, in the same oblique convexity, the distance between the projection position of the first adhesive portion on the skin-friendly base layer and the second adhesive portion is not less than the distance between the second adhesive portion and the third adhesive portion.

[0009] When the projection position of the first bonding part on the skin-friendly base layer and the spacing between the second bonding part and the spacing between the second bonding part and the third bonding part are the same, ultraviolet rays need to pass through the anti-UV textile layer three times when vertically entering the fabric from any position, and a better anti-UV effect can be achieved at this time. When the spacing between the first bonding part and the second bonding part is small, the coverage between the oblique wrinkles is insufficient, and ultraviolet rays only need to pass through the anti-UV textile layer once from certain positions to reach the skin-friendly base layer. When the spacing between the first bonding part and the second bonding part is too large, the weight of the anti-UV textile layer will increase, affecting the lightness of the fabric. Therefore, preferably, when the spacing between the second bonding part and the third bonding part is a, the spacing between the first bonding part and the second bonding part should be a~1.2a.

[0010] Furthermore, a first air cavity connected to the skin-friendly base layer is formed between the first oblique edge and the second oblique edge located in the same oblique convexity.

[0011] Furthermore, a second air cavity connected to the wear-resistant base layer is formed between two adjacent oblique corrugations.

[0012] Furthermore, the anti-ultraviolet textile layer is provided with air holes connecting the adjacent first air cavity and the second air cavity. The provision of the air holes can improve the air circulation between the first air cavity and the second air cavity and improve the air permeability.

[0013] Furthermore, the pores are arranged on the first oblique edges. In the present invention, each first oblique edge is covered by a second oblique edge located in the same oblique convexity. When the pores are arranged on the first oblique edges, ultraviolet rays can be prevented from directly passing through the pores and through the anti-ultraviolet textile layer.

[0014] Furthermore, the anti-ultraviolet spun layer is formed by interweaving anti-ultraviolet yarns in warp and weft.

[0015] Furthermore, the anti-ultraviolet yarn comprises a special-shaped fiber with a plurality of edges and corners in the cross section, and inner grooves are formed between adjacent edges and corners. The special-shaped fiber can enhance the reflective effect and improve the interception rate of the anti-ultraviolet textile layer for ultraviolet rays.

[0016] Furthermore, an antifouling coating is provided on the outer side of the wear-resistant base layer.

[0017] Furthermore, the thickness of the anti-ultraviolet fabric does not exceed 0.15 mm.

[0018] In summary, the application of the utility model can achieve the following beneficial effects:

[0019] 1. The oblique wrinkles of the utility model form a covering structure, and ultraviolet rays need to pass through the anti-ultraviolet textile layer multiple times to reach the skin-friendly base layer. In the process of passing through the anti-ultraviolet textile line multiple times, the ultraviolet rays will be refracted and scattered in large quantities, thereby improving the anti-ultraviolet effect of the fabric.

[0020] 2. The covering structure formed between the oblique wrinkles of the utility model greatly improves the equivalent thickness of the anti-ultraviolet textile layer, and the textile thickness and textile density of the anti-ultraviolet textile layer body can be reduced, so that air can more easily penetrate the anti-ultraviolet textile layer, thereby solving the problem of the existing anti-ultraviolet fabric being thick and stuffy.

[0021] 3. The wavy structure of the anti-ultraviolet textile layer of the utility model can be extended to a large extent when subjected to tension, so that the fabric has good tensile elasticity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] Reference Figure 1 The utility model provides an anti-ultraviolet fabric, which includes a skin-friendly base layer 1 close to the human skin when in use, a wear-resistant base layer 2 relatively located on the outside when in use, and an anti-ultraviolet textile layer 3 sandwiched between the skin-friendly base layer and the wear-resistant base layer;

[0027] The anti-ultraviolet spun layer is formed by repeatedly arranging a plurality of oblique corrugations 31 protruding toward the wear-resistant base layer, and each of the oblique corrugations includes a first oblique side 311 and a second oblique side 312 connected at an angle; on the side close to the wear-resistant base layer, the first oblique side and the second oblique side of the same oblique corrugation are integrally connected, and the oblique corrugations form a first adhesive portion 313 connected to the wear-resistant base layer; on the side close to the skin-friendly base layer, the first oblique side and the second oblique side of the same oblique corrugation are separated from each other, and the oblique corrugations form a second adhesive portion 314 and a third adhesive portion 315 connected to the skin-friendly base layer; of two adjacent oblique corrugations, the first adhesive portion of one oblique corrugation is integrally connected to the second adhesive portion of the other oblique corrugation;

[0028] In the same oblique corrugation, the projection position of the first adhesive portion on the skin-friendly base layer does not fall between the second adhesive portion and the third adhesive portion, but crosses the second adhesive portion. Specifically, the distance between the projection position of the first adhesive portion and the second adhesive portion is not less than the distance between the second adhesive portion and the third adhesive portion. When multiple oblique corrugations are connected, refer to Figure 1 In the orientation shown, of the two adjacent oblique corrugations, the projection of the first adhesive portion of the first oblique corrugation on the right side on the skin-friendly base layer passes over the second adhesive portion of the second oblique corrugation on the left side, so that the second oblique side of the second oblique corrugation in the projection direction of the skin-friendly base layer is covered by the first oblique corrugation. When an arbitrary vertical line is drawn perpendicular to the fabric, it will pass through the anti-ultraviolet spun layer at least three times. Therefore, in this embodiment, the equivalent thickness of the anti-ultraviolet spun layer is equal to three times the thickness of its own body. Compared with the solution of directly thickening the anti-ultraviolet spun layer to three times, the anti-ultraviolet spun layer provided in this embodiment is thinner and more breathable, and more comfortable to use. In addition, when ultraviolet light passes through the anti-ultraviolet spun layer multiple times, a large amount of refraction and scattering will occur, further improving the anti-ultraviolet effect.

[0029] In the same oblique corrugation, a first air cavity 32 connected to the skin-friendly base layer is formed between the first oblique edge and the second oblique edge, and a second air cavity 33 connected to the wear-resistant base layer is formed between two adjacent oblique corrugations. When the fabric is subjected to force, the gas in the first air cavity and the second air cavity can be exchanged with each other or with the outside world, thereby improving the air permeability and sweat permeability of the fabric, and having higher comfort when used in light outdoor sportswear. In addition, air holes 316 are arranged on the first oblique edge, and the air holes connect the adjacent first air cavity and the second air cavity, thereby further improving the fluidity between the first air cavity and the second air cavity. At the same time, the air holes are covered by the second oblique edge, thereby preventing ultraviolet rays from directly passing through the air holes, thereby ensuring anti-ultraviolet performance.

[0030] The skin-friendly base layer and the wear-resistant base layer described in the utility model can be further compounded with other functional layers to improve the functionality of the fabric. Figure 1For example, an antifouling coating is provided on the outer side of the wear-resistant base layer, and the antifouling coating can prevent liquid stains from adhering to and penetrating into the fabric.

[0031] The anti-ultraviolet spun layer of the utility model is formed by interweaving the anti-ultraviolet yarn in warp and weft, and the anti-ultraviolet yarn contains anti-ultraviolet fiber, and the anti-ultraviolet fiber refers to artificial synthetic fiber with anti-ultraviolet component added to the production raw material, such as polyester, and the anti-ultraviolet yarn can be formed by twisting multiple bundles of anti-ultraviolet fibers, or by twisting the anti-ultraviolet fibers and other fibers together. In some embodiments, refer to Figure 2 The fibers constituting the anti-ultraviolet yarn include special-shaped fibers 34, the cross-section of the special-shaped fibers includes a plurality of edges and corners 341, and inner grooves 342 are formed between adjacent edges and corners. The provision of the special-shaped fibers can enhance the reflective effect and further improve the anti-ultraviolet effect of the anti-ultraviolet spinning layer.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
