Abstract
Description
Technical Field
[0001] The utility model relates to the field of textiles, and more specifically, to an anti-ultraviolet protective fabric. Background Art
[0002] Most of the existing anti-ultraviolet protective fabrics achieve anti-ultraviolet by adding auxiliaries. However, these auxiliaries will gradually volatilize during long-term use, resulting in the surface of the fabric becoming rough, and once the fabric is damaged or worn, it cannot be used. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned existing technologies, and provide an anti-ultraviolet protective fabric. By weaving and combining the characteristics of acrylic fibers, bubbles that reflect ultraviolet rays are formed on the outermost side of the fabric, replacing the traditional anti-ultraviolet function formed by auxiliaries. The bubble layer and the base fabric layer are connected through the first connection point and the second connection point, and a protective layer is formed at the location of the first connection point and the second connection point. The protective layer uses nylon fibers to shield the ultraviolet rays that cannot be reflected by the bubbles, so that the anti-ultraviolet performance of the fabric will not disappear due to long-term use, damage or wear. The base fabric layer is woven with cotton fibers that are thicker than the bubble layer and the protective layer, which not only increases the structural stability of the fabric but also makes it more comfortable and breathable when worn by the human body.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The utility model discloses an anti-ultraviolet protective fabric, which includes a bubble layer and a base fabric layer. The bubble layer includes bubbles arranged in a matrix and a connecting part that connects all the bubbles. The bubbles protrude in a direction away from the base fabric layer. The bubble layer includes a first connection point, and the base fabric layer includes a second connection point. The bubble layer and the base fabric layer are connected through the first connection point and the second connection point, so that a protective layer is formed in the space where the first connection point and the second connection point are located.
[0006] Further, the height difference between the highest point of the bubble and the connecting part is 0.3 mm - 2.5 mm.
[0007] Further, the first connection point is located at the connecting part, and the first connection point is located at the center of a square unit composed of four bubbles.
[0008] Further, the second connection point is located at the projection of the center of the bubble on the base fabric layer.
[0009] Further, the height of the protective layer is the distance between the connecting part and the upper end surface of the base fabric layer, and the height of the protective layer is 0.5 mm - 1.6 mm.
[0010] Further, the first connection node is respectively connected to the four second connection nodes around it, and the second connection node is respectively connected to the four first connection nodes around it.

The twenty-first row of coils is the same as the ninth row of coils. The twenty-second row of coils is the same as the seventh row of coils. The twenty-third row of coils is the same as the eighth row of coils. The twenty-fourth row of coils is the same as the ninth row of coils.
[0012] Further, the first to sixth rows of coils and the thirteenth to eighteenth rows of coils are knitted to form the bubble layer.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] As Figure 1 —3 shows, an anti-ultraviolet protective fabric includes a bubble layer 100 and a base fabric layer 200. Refer to Figure 3, the 24 route loops are arranged horizontally in a cycle. The first route loop horizontal row forms loops with needles A, C, and D, and does not form a loop with needle B. The first to sixth route loop horizontal rows are the same. The seventh route loop horizontal row forms loops with needles A and C, and does not form loops with needles B and D. The eighth route loop horizontal row forms loops with needles B and D, and does not form loops with needles A and C. The ninth route loop horizontal row does not form loops with needles A, B, C, and D. The tenth route loop horizontal row is the same as the seventh route loop horizontal row. The eleventh route loop horizontal row is the same as the eighth route loop horizontal row. The twelfth route loop horizontal row is the same as the ninth route loop horizontal row. The thirteenth route loop horizontal row forms loops with needles A, B, and C, and does not form a loop with needle D. The thirteenth to eighteenth route loop horizontal rows are the same. The nineteenth route loop horizontal row is the same as the seventh route loop horizontal row. The twentieth route loop horizontal row is the same as the eighth route loop horizontal row. The twenty-first route loop horizontal row is the same as the ninth route loop horizontal row. The twenty-second route loop horizontal row is the same as the seventh route loop horizontal row. The twenty-third route loop horizontal row is the same as the eighth route loop horizontal row. The twenty-fourth route loop horizontal row is the same as the ninth route loop horizontal row.
[0023] The first to sixth route loop horizontal rows and the thirteenth to eighteenth route loop horizontal rows are knitted to form the bubble layer 100. The bubble layer 100 includes bubbles 110 arranged in a matrix and connecting parts 120 that connect all the bubbles 110. The bubbles 110 bulge away from the base fabric layer 200, and the height difference between the highest point of the bubbles 110 and the connecting parts 120 is 0.3 mm - 2.5 mm. Preferably, the height difference between the highest point of the bubbles 110 and the connecting parts 120 is 0.5 mm. The first to sixth route loop horizontal rows and the thirteenth to eighteenth route loop horizontal rows use 75D acrylic fibers. Because acrylic fibers have good ultraviolet reflection ability, when knitting, the bubbles 110 are formed by knitting acrylic fibers on the outermost layer of the fabric. Since the bubbles 110 are convex, when ultraviolet rays irradiate the surface of the bubbles 110, part of the ultraviolet rays are reflected, part of them are absorbed by the acrylic fibers when passing through the bubbles 110, and the rest will pass through the gaps between the fibers of the bubbles 110.
[0024] The 7th course loop row, the 9th course loop row, the 10th course loop row, the 12th course loop row and the 19th course loop row, the 21st course loop row, the 22nd course loop row, the 24th course loop row are knitted to form the base fabric layer 200. And the 7th course loop row, the 9th course loop row, the 10th course loop row, the 12th course loop row and the 19th course loop row, the 21st course loop row, the 22nd course loop row, the 24th course loop row use 32s cotton fiber. Because 32s cotton fiber is thicker than 75D acrylic fiber, so under the same number of needles knitting, the base fabric layer 200 knitted by 32s cotton fiber is tighter. Therefore, when part of the ultraviolet rays pass through, because the cotton fibers of the base fabric layer 200 are relatively tight and the gaps between the fibers are small, when the ultraviolet rays pass through the bubble layer 100 and reach the base fabric layer 200, the ultraviolet rays are absorbed by the cotton fibers and cannot penetrate. However, because the cotton fibers have good air permeability, the fabric will not feel stuffy when worn.
[0025] The bubble layer 100 includes the first connection point 400, and the base fabric layer 200 includes the second connection point 500. The bubble layer 100 and the base fabric layer 200 are connected through the first connection point 400 and the second connection point 500. Refer to Figure 2 , the first connection point 400 is located at the connection part 120, and the first connection point 400 is located at the center of the square unit composed of four bubbles 110. The second connection point 500 is located at the projection of the center of the bubble 110 on the base fabric layer 200. And the first connection point 400 is respectively connected to the four second connection points 500 around it, and the second connection point 500 is respectively connected to the four first connection points 400 around it. Connecting the two layers through the connection points makes a penetration formed between the bubble layer 100 and the base fabric layer 200, so that the ultraviolet rays can be blocked layer by layer.
[0026] The 8th course loop row and the 11th course loop row are knitted to form the first connection point 400, and the 20th course loop row and the 23rd course loop row are knitted to form the second connection point 500. And the 8th course loop row, the 11th course loop row, the 20th course loop row, the 23rd course loop row use 100D nylon fiber. Refer to Figure 1, a protective layer 300 is formed in the space where the first connection node 400 and the second connection node 500 are located. The height of the protective layer 300 is the distance between the connecting portion 120 and the upper end surface of the base fabric layer 200. The height of the protective layer 300 is 0.5 mm - 1.6 mm. Preferably, the height of the protective layer 300 is 0.8 mm, and the protective layer 300 is hollow. Therefore, the protective layer 300 not only connects the bubble layer 100 and the base fabric layer 200, but also is formed by weaving nylon fibers. It captures ultraviolet rays between the bubble layer 100 and the base fabric layer 200. When part of the ultraviolet rays penetrate the bubble layer 100 and do not reach the base fabric layer 200, the protective layer 300 can capture and shield part of the ultraviolet rays, so that the base fabric layer 200 cannot be irradiated by ultraviolet rays. Although the base fabric layer 200 is breathable, due to the relatively thick yarn count, the base fabric layer 200 is woven tightly, and the protective layer 300 is hollow. Therefore, an air circulation channel is formed between the bubble layer 100 and the base fabric layer 200, so that the base fabric layer 200 will not be too stuffy and can quickly circulate air, thereby improving the air permeability of the base fabric layer 200 and making the human body more comfortable when wearing.
[0027] When the fabric comes into contact with ultraviolet rays, the bubble layer 100 reflects the ultraviolet rays, and part of them are absorbed while the other part penetrates and enters the protective layer 300. The protective layer 300 will shield part of the ultraviolet rays and let part of them directly reach the base fabric layer 200. The base fabric layer 200 absorbs the remaining ultraviolet rays through its tight weaving, so that the human body cannot contact the ultraviolet rays. It uses 22 stitches / 30 inches - 28 stitches / 34 inches. Preferably, it uses 28 stitches / 30 inches, and the gram weight is 180 g / m² - 210 g / m². Preferably, the gram weight is 195 g / m², so that the overall use of the fabric is not heavy.
[0028] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
