[0019] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment: Cool and moisture-dissipating polyester fabric and its processing technology, such as Figure 1 and Figure 4 As shown, it includes an inner layer 1 and an outer layer 2 which are fixedly connected to each other, the warp and weft of the inner layer 1 are both set as cool yarns 11, the inner layer 1 is made by feeding the cool yarns 11 into an air-jet loom and weaving them through a convex strip structure, the cool yarns 11 are twisted by a twisting machine to form two first strands 12, the first strands 12 are twisted by a twisting machine to form polyester shaped fibers with a Y-shaped cross section, the polyester fibers are shaped to increase the size of the internal voids and the surface area, thereby improving the moisture dissipation and air permeability of the polyester fibers, the polyester shaped fibers with a Y-shaped cross section are spun by a spinneret, and the polyester raw material used to make the polyester shaped fibers is added with mica powder 13 accounting for 39%, the mica powder 13 has good thermal conductivity, thereby enhancing the thermal conductivity of the polyester shaped fibers, so that the manufactured inner layer 1 can quickly absorb the body surface temperature when it is against the skin, thereby bringing a cool feeling.

[0021] like Figure 1 and Figure 5As shown, the warp and weft of the outer layer 2 are both set as moisture-dispersing yarns 14. The outer layer 2 is made by feeding the moisture-dispersing yarns 14 into an air-jet loom and alternately weaving through an openwork structure and a plain structure. The moisture-dispersing yarns 14 are formed by twisting a first strand 12 and a second strand 15 through a twisting machine. The second strand 15 is formed by twisting flax fibers through a twisting machine. The flax fibers have stronger hygroscopicity and air permeability than polyester shaped fibers. At the same time, the flax fibers can quickly disperse the internally absorbed water due to their special porous structure. Therefore, the hygroscopicity of the inner layer 1 is less than that of the outer layer 2, so that the moisture absorbed in the inner layer 1 can be transferred to the second strand 15 in the outer layer 2 for rapid dissipation, thereby improving the moisture dissipation speed of the fabric. At the same time, the heat in the inner layer 1 can be transferred to the first strand 12 in the outer layer 2 and fully contact with the outside air to dissipate heat.

[0022] like Figure 1-Figure 3 As shown, a plurality of heat dissipation strips 3 are provided on the side of the inner layer 1 close to the outer layer 2, the length of the heat dissipation strips 3 is the same as the width of the inner layer 1, and the plurality of heat dissipation strips 3 are arranged in an array along the length direction of the inner layer 1, and the plurality of heat dissipation strips 3 are all formed integrally on the inner layer 1 by weaving a convex strip tissue, the outer layer 2 includes a plurality of fixing portions 4 and a plurality of breathable portions 5 staggered along its length direction, the breathable portion 5 is provided with a plurality of breathable holes 10 arranged in an array, the breathable portion 5 and the plurality of breathable holes 10 provided thereon are all formed integrally by weaving a perforated tissue, the fixing portion 4 is made by weaving a plain weave tissue, the cross-sectional shape of the fixing portion 4 is U-shaped, the cross-sectional shape of the breathable portion 5 is arc-shaped, and a moisture dissipation groove 44 is provided on the side of the fixing portion 4 away from the inner layer 1, and the contact area between the outer layer 2 and the air is increased by the plurality of moisture dissipation grooves 44 and the arc-shaped breathable portion 5, thereby enhancing the moisture dissipation performance of the outer layer 2.

[0023] like Figure 1-Figure 3As shown, a protrusion 6 and a plurality of recesses 7 are respectively provided on the side where the fixing portion 4 and the inner layer 1 are close to each other, the width of the fixing portion 4 is the same as the width of the recess 7, the curvature of the protrusion 6 is the same as the curvature of the recess 7 and the curvature of the bottom surface of the moisture dissipation groove 44, and the peripheral wall of the protrusion 6 is against the inner wall of the recess 7, so that a plurality of ventilation spaces 8 are formed between the gaps between a plurality of adjacent fixing portions 4 and a plurality of breathable portions 5, a plurality of heat dissipation strips 3 and the inner layer 1, and the air content inside the fabric is increased by the plurality of ventilation spaces 8, the distance between the breathable portion 5 and the inner layer 1 is greater than the thickness of the heat dissipation strip 3, and the width of the heat dissipation strip 3 is less than the breathable portion 5. The width of the air portion 5 leaves a gap between the heat dissipation strip 3 and the outer layer 2. The contact area between the inner layer 1 and the air is increased by a plurality of heat dissipation strips 3, thereby improving the heat dissipation performance of the inner layer 1. The polyester shaped fiber has good resilience, so that the fabric made can quickly recover to its original shape after stretching. The overall ductility of the fabric is increased by a plurality of moisture dissipation grooves 44, a plurality of ventilation spaces 8, a plurality of air holes 10 and a plurality of ventilation holes 9, so that the fabric can be closely attached to the skin surface when worn. The heat conduction effect can be improved by increasing the contact area between the inner layer 1 and the skin, thereby improving the cool feeling of the fabric when worn.

[0024] like Figure 1-Figure 3 As shown, the several air holes 10 on the breathable portion 5 are interconnected with the ventilation space 8, the inner layer 1 is provided with a several air holes 9, and the several air holes 9 are arranged in an array along the width direction of the inner layer 1 between the adjacent heat dissipation strips 3 and the fixing portion 4, so that the several air holes 9 are interconnected with the ventilation space 8, and the air circulation effect on both sides of the fabric is improved by the several ventilation spaces 8, the several air holes 9 and the several air holes 10 that are interconnected. The air holes 9 are located directly below the air holes 10, so that the air circulation on both sides of the fabric is smoother. The good air circulation effect can improve the heat dissipation effect of the inner layer 1 and the overall moisture dissipation performance of the fabric. The moisture in the fabric will absorb the surrounding heat during the moisture dissipation and vaporization process. Therefore, the good moisture dissipation performance of the fabric will continuously take away heat during the moisture dissipation process, thereby prolonging the cooling effect provided by the fabric.

[0025] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the inner layer 1 and the outer layer 2 are fixed by hot pressing of the equipment body 16, and the protrusion 6, the depression 7, the moisture dissipation groove 44, the air permeable part 5 of the arc-shaped cross section, and the fixing part 4 of the U-shaped cross section are all formed integrally when the inner layer 1 and the outer layer 2 are fixed by hot pressing of the equipment body 16. The equipment body 16 includes a cloth rolling roller 17, a cloth rolling roller 2 18, a guide roller 19, a guide roller 20, a hot pressing device 21, a support plate 22, a piercing device 23 and a cooling chamber 24. The support plate 22 is located between the hot pressing device 21 and the piercing device 23. Three penetration grooves 25 and three symmetrically arranged penetration grooves 25 are respectively provided on both sides of the equipment body 16. A support plate 27 is slidably connected between a penetration groove 25 and a penetration groove 26 symmetrically arranged, and the width of the penetration groove 25 and the width of the penetration groove 26 are the same as the width of the support plate 27, thereby limiting the lateral swing of the support plate 27 when sliding, and the side of the penetration groove 26 close to the penetration groove 25 is chamfered, so as to facilitate the support plate 27 to pass through the penetration groove 26, and the length of the support plate 27 is greater than the width of the equipment body 16. The side walls of the equipment body 16 are made of aluminum alloy and have high strength. Therefore, the penetration groove 26 and the penetration groove 25 can provide a good support effect for the support plate 27.

[0026] like Figure 6-Figure 9 As shown, three support plates 27 are arranged in an array along the length direction of the equipment body 16 between the support plate 1 22 and the hot pressing device 21, and the distance between adjacent support plates 27 is the same as the distance between adjacent air permeable parts 5. The equipment body 16 is provided with a driving device 28 for driving the three support plates 27 to move simultaneously on one side thereof where the penetration groove 25 is provided. The driving device 28 includes two fixed plates 37, a driving motor 38, a rotating shaft 39, a moving plate 40 and a plurality of supporting shafts 41. The rotating shaft 39 and the plurality of supporting shafts 41 are all rotatably connected between the two fixed plates 37. A rack is provided on the top surface of the moving plate 40, and a gear meshing with the rack is provided on the rotating shaft 39. The drive motor 38 is a servo motor for driving the rotating shaft 39 to rotate, and the movable plate 40 is driven to move longitudinally by the meshing of the gear and the rack. One end of the three support plates 27 close to the insertion slot 25 is fixedly connected to the side of the movable plate 40 close to the equipment body 16, and a plurality of support roller arrays are arranged on both sides of the movable plate 40 along the height direction of the equipment body 16. The support rollers abut against the movable plate 40, thereby limiting the swing of the movable plate 40 along the height direction of the equipment body 16 when moving, thereby ensuring the stability of the three support plates when moving. When the movable plate 40 moves to abut against the side wall of the equipment body 16, the three support plates 27 respectively pass through the three exit slots 26.

[0027] like Figure 7-Figure 9As shown, the cloth rolling roller 17 is used to convey the inner layer 1. When conveying, the inner layer 1 is conveyed between the support plate 22 and the plurality of support plates 27 after changing the conveying direction through the guide roller 19. The cloth rolling roller 218 is used to convey the outer layer 2.

The components such as the pressure cylinder 43 realize the telescopic effect of the hydraulic cylinder 43 after the hydraulic oil in the oil tank is extracted by the hydraulic pump 42 and sent to the hydraulic cylinder 43. A plurality of piercing members 31 are fixed in an array on the side of the contact plate 30 close to the support plate. The support plate is provided with a plurality of through holes 32 for the plurality of piercing members 31 to pass through. The hot pressing device 21 includes a driving member 2 33 and a hot pressing plate 34. The driving member 2 33 is used to drive the hot pressing plate 34 to reciprocate along the height direction of the equipment body 16. The hot pressing plate 34 is made of copper material and can quickly transfer heat. The heat conducting plate is heated by electricity. The support plate 1 22, the support plate 27, the contact plate 30 and the movable plate 40 are all made of aluminum alloy.

[0028] like Figure 6-Figure 9 As shown, a hot pressing groove 35 and two hot pressing blocks 36 are integrally formed on one side of the hot pressing plate 34 close to the support plate 1 22. The two hot pressing blocks 36 are symmetrically arranged on both sides of the hot pressing groove 35 along the length direction of the equipment body 16 and are located between adjacent support plates 27.

At this time, the three support plates 27 are respectively located directly below the three adjacent air permeable portions 5. The support plate 27 is located at one end of the groove 26 and is flat, so as to facilitate the insertion of the support plate 27 between the inner layer 1 and the outer layer 2.

[0029] like Figure 1-Figure 9As shown, when the three support plates 27 respectively pass through the three outlet grooves 26, the driving member 2 33 drives the hot pressing plate 34 to move downward, and the air-permeable portion 5 is hot-pressed by the hot pressing groove 35 and the support plate 27 so that the cross section of the air-permeable portion 5 is formed into an arc shape, and the inner layer 1 and the fixed portion 4 are hot-pressed by the hot pressing block 36 and the support plate 1 22 so that the cross section of the fixed portion 4 is formed into a U shape, and a protrusion 6 and a depression 7 are respectively formed on the side where the fixed portion 4 and the inner layer 1 are hot-pressed against each other, and at the same time, the protrusion 6 and the depression 7 are hot-pressed and fixed at the contact point, the distance that the puncture member 31 passes through the support plate 1 22 is greater than the thickness of the inner layer 1, the diameter of the puncture member 31 is the same as the diameter of the vent hole 9, the distance between adjacent vent holes 9 is the same as the distance between adjacent puncture members 31, and the inner layer 1 and the outer layer 2 are hot-pressed by the hot pressing plate 34.

When the two hot pressing blocks 36 perform hot pressing processing on the inner layer 1, a large tension is formed on the inner layer 1 located between the two hot pressing blocks 36, so that it is convenient for the piercing member 31 to penetrate the inner layer 1. After the ventilation holes 9 are opened, the driving member 29 and the driving member 2 33 respectively drive the resistance plate 30 and the hot pressing plate 34 to move in directions away from each other at the same time.
