Description
Technical Field
[0001] The utility model relates to the technical field of textiles, and more particularly to light-shielding and breathable chemical fiber fabrics. Background Art
[0002] Chemical fiber fabric is a common yarn fabric, usually woven with chemical fibers such as polyester, nylon, spandex, acrylic, and polypropylene. Chemical fibers have good light-shielding properties due to their high density, so that the chemical fiber fabrics made from them can effectively block the penetration of sunlight. Therefore, chemical fiber fabrics are widely used in the production of outdoor products such as sun protection clothing, face towels, sleeves, umbrellas, tents, etc.
[0003] However, the higher density of chemical fibers reduces the open space within the fibers, which is not conducive to the circulation of gas. At the same time, in order to maintain good light-shielding properties, the weaving density of chemical fiber fabrics is usually higher, thereby reducing the size of the gaps formed by the weaving of the fabric, further reducing the air circulation effect on both sides of the chemical fiber fabric, making the breathability of chemical fiber fabrics relatively poor, which easily produces a stuffy feeling when worn, affecting wearing comfort.
[0004] Therefore, it is necessary to propose new solutions to solve the problem of relatively poor air permeability of chemical fiber fabrics. Utility Model Content

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0020] Example: light-shielding breathable chemical fiber fabric, such as Figure 1 and Figure 2 As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other, the inner layer 1 includes a plurality of breathable portions 12 and a plurality of shading portions 13 staggered along its length, the outer layer 2 includes a plurality of breathable portions 15 and a plurality of shading portions 16 staggered along its length, and a plurality of shading strips 3 and a plurality of shading strips 4 are respectively provided on the side where the inner layer 1 and the outer layer 2 are close to each other. The width of the shading portion 13 is the same as the width of the shading portion 16, and the width of the shading strip 3 is the same as the width of the shading portion 16. The shading strip 1 3 is the same width as the shading portion 13, and is integrally formed on the side of the shading portion 13 close to the outer layer 2. The width of the shading strip 2 4 is the same width as the shading portion 2 16, and the shading strip 2 4 is integrally formed on the side of the shading portion 2 16 close to the inner layer 1. The thickness of the fabric at the shading portion 13 and the shading portion 2 16 is increased by a plurality of shading strips 1 3 and a plurality of shading strips 2 4, thereby improving the shading effect of the fabric at the shading portion 13 and the shading portion 2 16.
[0021] like Figure 1 、 Figure 2 and Figure 4As shown, the inner layer 1 is provided with a plurality of air holes 10, and the outer layer 2 is provided with a plurality of air holes 2 11. The warp and weft yarns of the inner layer 1, and the warp and weft yarns of the outer layer 2 are all set as shading yarns 17. The inner layer 1 and the outer layer 2 are both made by feeding the shading yarn 17 into an air-jet loom and weaving the shading yarn 17 alternately through an open-hole structure and a ribbed structure. The shading yarn 17 is made by spirally winding a first strand 18 on a second strand 19 through a ring spinning machine. The first strand 18 is twisted by a twisting machine to form bamboo charcoal fiber, and the second strand 19 is twisted by a twisting machine to form acrylic fiber. The bamboo charcoal fiber has certain light-shielding properties and good air permeability. Acrylic fiber has a stronger light-shielding property than bamboo charcoal fiber, so that the fabric made of bamboo charcoal fiber and acrylic fiber has a certain breathability while ensuring the light-shielding effect. A plurality of air holes 10 are arranged in an array on the air-permeable part 12, and the air-permeable part 12 and the plurality of air holes 10 opened thereon are all formed integrally on the inner layer 1 through the weaving method of the through-hole tissue. A plurality of the air holes 11 are arranged in an array on the air-permeable part 15, and the air-permeable part 15 and the plurality of air holes 11 opened thereon are all formed integrally on the outer layer 2 through the weaving method of the through-hole tissue. The breathability of the fabric is improved by the plurality of air holes 10 and the plurality of air holes 11.
[0022] like Figure 1-Figure 3 As shown, a plurality of depressions 1 5 and 2 6 are respectively provided on both sides of the inner layer 1, and the depressions 1 5 and 2 6 are staggered along the length direction of the inner layer 1. The depressions 1 5 and 2 6 are formed as a whole after the inner layer 1 is pleated at a plurality of breathable portions 12 by a pleating machine. A plurality of depressions 3 7 and 4 8 are respectively provided on both sides of the outer layer 2, and the depressions 3 7 and 4 8 are staggered along the length direction of the outer layer 2. The depressions 3 7 and 4 8 are formed as a whole after the outer layer 2 is pleated at a plurality of breathable portions 12 by a pleating machine. Several breathable parts 15 are pleated and formed as one body, the shading part 13 and the shading strip 3 are both formed as one body on the inner layer 1 by weaving a convex strip tissue, the shading part 16 and the shading strip 2 4 are both formed as one body on the outer layer 2 by weaving a convex strip tissue, the shading strip 1 3 and the shading strip 2 4 are abutted on one side close to each other, and the shading part 13 and the shading part 2 16 are located at the abutting part of the shading strip 1 3 and the shading strip 2 4 and are sewn and fixed by a sewing machine using a shading yarn 17.
[0023] like Figure 1-Figure 3As shown, recess 2 6 and recess 3 7 are respectively located on the side where the inner layer 1 and the outer layer 2 are close to each other, and recess 4 8 is located directly above recess 2 6, so that the gap between recess 2 6 and several recesses 3 7, adjacent shading strips 1 3 and adjacent shading strips 2 4 forms a breathable space 9, and several breathable holes 10 and several breathable holes 2 11 are interconnected with the breathable space 9, and the contact area between the inner layer 1 and the skin is reduced by several shading parts 13. The depth of recess 1 5 is greater than the depth of recess 2 6, so that a gap is left between the breathable part 12 and the skin, and a ventilation space 14 is enclosed between the breathable part 12 and the shading parts 13 on both sides thereof, and several breathable holes 10 are interconnected with the ventilation space 14. The air circulation effect on both sides of the fabric is improved through several interconnected breathable holes 10, breathable holes 2 11, ventilation space 9 and ventilation space 14, thereby further improving the overall breathability of the fabric.
[0024] like Figure 1 and Figure 2 As shown, a plurality of air holes 10 and a plurality of air holes 2 11 are staggered along the width direction of the inner layer 1. The staggered air holes 10 and air holes 2 11 can prevent sunlight from directly penetrating the fabric. A plurality of air permeable portions 2 15 after pleating form a plurality of inclined surfaces on the side of the outer layer 2 away from the inner layer 1, so that the outer layer 2 can reflect part of the sunlight. The inclined surfaces of the plurality of recesses 3 7 and the inclined surfaces of the plurality of recesses 2 6 enable the sunlight entering the fabric from the plurality of air holes 2 11 to be reduced in intensity after multiple refractions in the breathable space 9. The porous structure of the bamboo charcoal fiber can scatter sunlight. Since the bamboo charcoal fiber is spirally wound on the acrylic fiber, the sunlight entering the fabric can contact and diverge with the bamboo charcoal fiber during the refraction process, further reducing the intensity and penetration of the sunlight entering the fabric, and ensuring the shading effect of the fabric at the air permeable portion 12 and the air permeable portion 2 15.
