DETAILED DESCRIPTION
[0019] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Embodiment: The sun-proof polyester fabric, such as Figure 1-Figure 3 As shown, it includes an inner layer 1 and an outer layer 2 which are fixedly connected to each other. The inner layer 1 is made by feeding the sun-screen yarn 5 into a jet loom and weaving it alternately through a perforated structure and a plain structure. The sun-screen yarn 5 is twisted by a first strand 8 and a second strand 9 in an "S" twisting manner through a twisting machine. The first strand 8 is twisted by a twisting machine by twisting a polyester shaped fiber with a triangular cross-section. The polyester shaped fiber with a triangular cross-section is spun through a spinneret. The polyester fiber has good light-shielding properties. By shaping the polyester fiber, sunlight can be continuously reflected on the edges inside the polyester shaped fiber, thereby achieving the effect of weakening the intensity of sunlight. The second strand 9 is twisted by a twisting machine by twisting acrylic fiber. Acrylic fiber has a strong light-shielding property, so that the inner layer 1 made by blending the polyester shaped fiber and the acrylic fiber can effectively block the penetration of sunlight.
[0021] like Figure 1 and Figure 2 As shown, the weaving density of the inner layer 1 is 194*183 / cm², and the shading effect is further enhanced by increasing the weaving density of the inner layer 1. A plurality of ventilation holes 7 are penetrated through the inner layer 1, and an array of the plurality of ventilation holes 7 is arranged in a perforated tissue weaving area 11 on the inner layer 1. The plurality of ventilation holes 7 are integrally formed on the inner layer 1 by weaving the perforated tissue. The plurality of ventilation holes 7 improves the breathability of the inner layer 1, thereby preventing the inner layer 1 from feeling stuffy when it is against the skin.
[0022] like Figure 1 , Figure 3 and Figure 4As shown, the outer layer 2 is formed by feeding the divergent yarn 13 into a jet loom and weaving it in a plain weave manner, the divergent yarn 13 is formed by spirally winding a third strand 14 on a first strand 8 through a ring spinning process, the third strand 14 is twisted by a twisting machine to form bamboo charcoal fiber, and the dense pores in the bamboo charcoal fiber enable it to have a good divergent effect on sunlight and can effectively weaken the intensity of sunlight, so that the outer layer 2 formed by blending the bamboo charcoal fiber with the polyester shaped fiber has good divergence and can weaken the intensity of sunlight before the sunlight enters the polyester cloth.
[0023] like Figure 1 As shown, the bamboo charcoal fiber has good hygroscopicity, air permeability and moisture dissipation. By coating the bamboo charcoal fiber on the polyester shaped fiber, the outer layer 2 has good hygroscopicity and air permeability on both sides, so that the outer layer 2 can timely remove the moisture inside it. The hygroscopicity of the bamboo charcoal fiber is greater than that of the polyester fiber and the acrylic fiber, so that the hygroscopicity of the outer layer 2 is greater than that of the inner layer 1. Therefore, the polyester cloth made can absorb the sweat generated by the wearer's skin in time when worn and guide it to the outer layer 2 for rapid dissipation, avoiding the discomfort caused by the polyester cloth sticking to the skin due to sweat.
[0024] like Figure 1 , Figure 4 and Figure 6 As shown, a laser cutting machine is used to symmetrically open a plurality of rectangular through grooves 3 in the outer layer 2 along its length direction, and the air permeability of the outer layer 2 is improved by the plurality of through grooves 3. A U-shaped light absorbing member 4 is provided on the inner walls on both sides of the through groove 3 along its length direction, and both ends of the light absorbing member 4 pass through the through groove 3. The two sides of the light absorbing member 4 passing through the through groove 3 are respectively sewn and fixed to the two sides of the outer layer 2 by sun-proof yarns 5. The light absorbing member 4 is formed by feeding a divergent yarn 13 into a jet loom and weaving it into a base layer 33 in a plain weave manner, and then cutting it using a cutting machine. The plurality of light absorbing members 4 can have a divergent effect on the sunlight entering the polyester cloth, thereby weakening the intensity of the sunlight entering the polyester cloth. At the same time, the inner wall of the through groove 3 is reinforced to prevent the outer layer 2 from loosening after the through groove 3 is opened.
[0025] like Figure 1 and Figure 2As shown, the inner circumferential wall of the sunscreen component is offset against the two sides of the inner layer 1 and the inner wall of the through groove 3 in the length direction, the length of the through groove 3 is greater than the length of the light-absorbing component 4, the distance between adjacent light-absorbing components 4 is greater than zero and less than the width of the through groove 3, the inner layer 1 and the outer layer 2 are located between adjacent through grooves 3 and are sewn and fixed by sunscreen yarns 5, so that a breathable space 6 interconnected with the through groove 3 is formed between several adjacent light-absorbing components 4 and the inner layer 1 and the outer layer 2, the plain weave woven area 10 on the inner layer 1 is located directly below the through groove 3 and has a width greater than the width of the through groove 3, and the through-hole woven area is located on both sides of the through groove 3 in the length direction, thereby preventing sunlight from directly penetrating the polyester cloth through the through groove 3 and the air holes 7 and irradiating the skin.
[0026] like Figure 1 and Figure 2 As shown, when the inner layer 1 is sewn with the outer layer 2 by the sun-protection yarn 5, it is bent in the direction close to the outer layer 2 to form a depression 12. The width of the depression 12 is greater than the distance between the adjacent ventilation holes 7 along the length direction of the fabric, so that the depression 12 and the ventilation holes 7 are interconnected. The gap between the inner layer 1 and the skin and the air circulation effect are increased through a plurality of depressions 12. The interconnected ventilation spaces 6, through grooves 3, ventilation holes 7 and depressions 12 improve the air circulation effect between the inside and outside of the polyester cloth, thereby enhancing the air permeability and moisture dissipation of the polyester cloth, and at the same time further enhancing the divergence effect of the sunlight entering the polyester cloth, thereby achieving a good sun-protection and ventilation effect of the polyester cloth.

At this time, the two base layers 33 are cut simultaneously by the cutting device 19.
[0029] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, after the cutting device 19 cuts the base layer 33, the two moving blocks 18 continue to move in a direction away from each other to the top of the plurality of suturing devices 16, at which time the cut base layer 33 above the through slot 3 is driven to abut against the top surface of the outer layer 2, and the bottom surface of the moving block 18 is provided with a suturing groove 22 for the sewing needle in the suturing device to penetrate, and both the suturing device 16 and the suturing device 2 17 are provided with a driving motor 30 for driving the sewing needle inside to work, and the driving motor 30 is a servo motor, which can drive the sewing needle to perform reciprocating suturing work, and the two Both a sewing device 16 and a sewing device 2 17 are provided with a hydraulic motor 4 31 located on the outer side wall of the equipment body 15.

When the moving block 18 moves to the top of the sewing device 16, the light absorbing member 4 is fixed on the outer layer 2 through the sewing device 16. The hydraulic motor 1 26, the hydraulic motor 28, the hydraulic motor 3 29, and the hydraulic motor 4 31 all extract hydraulic oil to generate kinetic energy during operation, thereby realizing the reciprocating telescopic function of the hydraulic rod.
