Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fabrics, and more specifically, to an anti-ultraviolet chemical fiber fabric. Background Art
[0002] A fabric is a flat and soft piece formed by crossing, knotting, and connecting small flexible filaments.
[0003] Fabrics are usually the basic materials for making clothing and determine the performance of the finished clothing. Clothing is the most common and widely used daily necessity. For clothing, the properties it has are deeply concerned by people. Ultraviolet rays in sunlight are a major factor threatening health. Long-term exposure to ultraviolet rays may induce skin diseases. In the prior art, fabrics mainly reduce the amount of ultraviolet rays passing through by compounding a radiation-proof coating on the surface to reflect or absorb ultraviolet rays, or by increasing the density, thickness, and weight of the fabric.
[0004] However, by increasing the thickness and density of the fabric, the fabric will become thick and airtight. If this kind of fabric is used to make clothing, the wearer is likely to feel stuffy and sweaty. If the fabric is in a humid environment for a long time, the anti-ultraviolet substances on the fabric will also be affected, thus weakening the anti-ultraviolet effect.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model
[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an anti-ultraviolet chemical fiber fabric.
[0007] The above technical purpose of the utility model is achieved through the following technical solutions: The anti-ultraviolet chemical fiber fabric includes an inner layer and an outer layer fixedly connected to each other. Air-permeable through holes are provided on both the inner layer and the outer layer. The air-permeable through holes on the inner layer communicate with the air-permeable through holes on the outer layer, and their cross-sectional shape is V-shaped. The inner layer and the outer layer are woven from anti-ultraviolet yarns and sunscreen breathable yarns.
[0008] The utility model is further provided that: The end faces of the inner layer and the outer layer are covered with an anti-ultraviolet coating, and the anti-ultraviolet coating is formed by spraying an ultraviolet absorber by a spraying method.
[0009] The utility model is further provided that: The warp yarns of the inner layer and the outer layer are set as anti-ultraviolet yarns, the weft yarns of the inner layer and the outer layer are set as sunscreen breathable yarns, the warp density of the inner layer and the outer layer is 256 threads / 10 cm, and the weft density of the inner layer and the outer layer is 230 threads / 10 cm.
[0010] The present utility model is further configured such that the porosity of the inner layer and the outer layer is less than or equal to 2%.
[0011] The present utility model is further configured such that the inner layer and the outer layer are arranged in a variable plain weave, the weft yarn texture points of the inner layer and the outer layer are arranged to sink, the warp yarn texture points of the inner layer and the outer layer are arranged to float, and the texture cycle of the variable plain weave is arranged in sequence from left to right and from top to bottom as follows: float sink float sink float sink sink, sink float sink sink float sink float float, float sink float sink float sink sink, float sink float sink float sink sink, sink float sink sink float sink float float, float sink float sink float sink sink, sink float sink sink float sink float float, sink float sink sink float sink float float.
[0012] The present utility model is further configured such that the sun protection breathable yarn is formed by twisting a first strand and a second strand. The first strand is twisted by a first polyester profiled fiber, and the cross-section of the first polyester profiled fiber is arranged in a plum blossom shape. The second strand is twisted by ramie fibers.
[0013] The present utility model is further configured such that the anti-ultraviolet yarn is formed by twisting a second polyester profiled fiber and silver fiber, and the cross-section of the second polyester profiled fiber is arranged in a triangle shape.
[0014] In summary, the present utility model has the following beneficial effects: The inner layer and the outer layer woven by the sun protection breathable yarn and the anti-ultraviolet yarn have good anti-ultraviolet performance and breathable performance. The breathable through holes opened in the inner layer and the breathable through holes opened in the outer layer are interconnected, and their cross-section is in a V shape, which while ensuring the overall breathability of the fabric, also reduces the occurrence of ultraviolet rays directly irradiating the skin through the breathable through holes. By improving the overall breathability of the fabric, the fabric is less likely to be in a humid environment for a long time, which affects the anti-ultraviolet performance of the fabric itself.

[0020] The present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] An anti-ultraviolet chemical fiber fabric, such as Figure 1 shown, includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. Ventilation through-holes 3 are provided on both the inner layer 1 and the outer layer 2. The inner layer 1 and the outer layer 2 are woven by anti-ultraviolet yarns 7 and sunscreen breathable yarns 4. The double-layer structure of the inner layer 1 and the outer layer 2 thickens the thickness of the fabric. Combining the anti-ultraviolet yarns 7 and the sunscreen breathable yarns 4 improves the overall anti-ultraviolet ability of the fabric. The ventilation through-holes 3 located in the inner layer 1 and the ventilation through-holes 3 located in the outer layer 2 combine to form a through-hole with a V-shaped cross-section. Since the light is direct, the V-shaped cross-section can effectively prevent ultraviolet rays from directly irradiating the skin, while ensuring that the fabric has good anti-ultraviolet ability, improving the overall air permeability of the fabric. The end faces of the inner layer 1 and the outer layer 2 are covered with an anti-ultraviolet coating, and the anti-ultraviolet coating is formed by spraying an ultraviolet shielding agent by the spraying method.
[0022] As Figure 3 and Figure 4 shown, the inner layer 1 and the outer layer 2 are woven by sunscreen breathable yarns 4 and anti-ultraviolet yarns 7. The sunscreen breathable yarn 4 is formed by twisting a first strand and a second strand. The first strand is twisted by first polyester profiled fibers 5, and the cross-section of the first polyester profiled fiber 5 is set as a plum blossom shape. The second strand is twisted by ramie fibers 6. Both the polyester fiber and the ramie fibers 6 have good anti-ultraviolet performance, and the ramie fibers 6 also have good air permeability. Moreover, the polyester fiber with a plum blossom-shaped cross-section has the characteristic of gemstone luster and can effectively reflect ultraviolet rays, thus achieving the anti-ultraviolet effect. The anti-ultraviolet yarn 7 is formed by twisting second polyester profiled fibers 8 and silver fibers 9 through a twisting machine. The silver fibers 9 can filter out a part of ultraviolet rays and provide additional protection for the body. The triangular cross-section setting of the second polyester profiled fibers 8 has a luster effect and can reflect ultraviolet rays. Moreover, the polyester fiber has the characteristics of high strength and good elasticity, which can ensure the overall strength and durability of the fabric.
[0023] As Figure 3 and Figure 4 shown, people first need to twist the first polyester profiled fibers 5 through a twisting machine to obtain the first strand, and then take a number of ramie fibers 6 and twist them through a twisting machine to obtain the second strand. Then, the first strand and the second strand are put into a twisting machine to twist to obtain a sunscreen breathable yarn 4 with good air permeability and anti-ultraviolet performance. Then, the second polyester profiled fibers 8 and the silver fibers 9 are twisted through a twisting machine to obtain an anti-ultraviolet yarn 7 with excellent anti-ultraviolet performance.
[0024] Then people use an air-jet loom, such as Figure 2As shown, the inner layer 1 and the outer layer 2 are set as a variable plain weave. The weft yarn tissue points of the inner layer 1 and the outer layer 2 are set as sinking, and the warp yarn tissue points of the inner layer 1 and the outer layer 2 are set as floating. The tissue cycle of the variable plain weave is set as follows from left to right and from top to bottom: floating, sinking, floating, sinking, floating, sinking, sinking, sinking; sinking, sinking, sinking, floating, sinking, floating, floating, floating; floating, sinking, floating, floating, sinking, floating, sinking, sinking; floating, sinking, floating, floating, sinking, floating, sinking, sinking; sinking, sinking, sinking, floating, sinking, floating, floating, floating; floating, sinking, floating, floating, sinking, floating, sinking, sinking; sinking, sinking, sinking, floating, sinking, floating, floating, floating; sinking, sinking, sinking, floating, sinking, floating, floating, floating. According to the above method, the sunscreen breathable yarn 4 and the anti-ultraviolet yarn 7 are fed into an air-jet loom according to a weaving density of 256 warp yarns per 10 cm and 230 weft yarns per 10 cm, as Figure 1 shown. The inner layer 1 and the outer layer 2 with a tight structure and a porosity less than or equal to 2% are woven. Then, the inner layer 1 and the outer layer 2 are respectively placed on a laser drilling machine, and the horizontal angles of the inner layer 1 and the outer layer 2 are adjusted. A number of oblique breathable through-holes 3 are laser-drilled on the inner layer 1 and the outer layer 2. Then, the outer layer 2 is placed above the inner layer 1, and the breathable through-holes 3 of the inner layer 1 correspond to the breathable through-holes 3 of the outer layer 2, making it V-shaped in cross-section. Then, the inner layer 1 and the outer layer 2 are fixedly connected by sewing with yarn or by bonding. Finally, by spraying method, a PU coating agent is sprayed on the end faces of the inner layer 1 and the outer layer 2 facing away from each other, and then dried and subjected to necessary heat treatment to form an anti-ultraviolet film on the fabric surface.
[0025] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept 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 the protection scope of the present invention.
