[0002] Chemical fiber fabric is a common yarn fabric, usually woven with chemical fibers such as polyester, nylon, polyester, acrylic, and polypropylene. Chemical fibers have good elasticity due to their high density, which makes the chemical fiber fabrics not easy to relax and deform during daily wear, and have good shape retention. Therefore, chemical fiber fabrics are widely used in clothing, luggage, home textiles, outdoor products and other fields.

The polyester shaped fibers have good elasticity and resilience, so that the inner layer 1 has good shape retention, and the polyester fibers are shaped to obtain larger gaps and The surface area is increased, which improves the gas circulation effect and the penetration and diffusion of water, thereby improving the hygroscopicity and air permeability of polyester fiber. Cotton fiber has stronger hygroscopicity and air permeability than polyester shaped fiber. The hygroscopic yarn 14 made by wrapping cotton fiber on polyester shaped fiber has good hygroscopicity and air permeability while ensuring good elasticity. The cotton fiber will first contact the skin, so that the inner layer 1 can absorb the sweat produced by the skin in time. The skin-friendly and soft touch of the cotton fiber further improves the comfort of the inner layer 1.

Flax fiber has stronger moisture absorption and air permeability than cotton fiber. The moisture-dispersing yarn 15 made by wrapping flax fiber on polyester shaped fiber has strong moisture absorption and air permeability while ensuring good elasticity, so that the outer layer 2 has good air permeability, thereby ensuring the overall air permeability of the fabric and avoiding the fabric from feeling stuffy when worn. The special porous structure of flax fiber enables it to quickly disperse the absorbed moisture, so that the moisture absorbed in the inner layer 1 can be promptly transferred to the outer layer 2 for rapid dissipation, and the outer layer 2 can fully contact the external airflow, further improving the moisture dissipation speed of the outer layer 2.

At the same time, the several ventilation spaces 10 and the several ventilation spaces 13 improve the ductility of the fabric and the practical effect of the fabric. The contact area between the fabric and the skin is reduced through the several ventilation spaces 13, and the air circulation effect between the fabric and the skin is increased, so that the fabric is not easy to stick to the skin and has a comfortable wearing feeling.

The lengths of the hot pressing plate 30, the hot pressing plate 42 and the molding die 24 are all greater than the width of the fabric.

[0027] like Figure 1-Figure 8As shown, the driving device 1 31 and the driving device 2 43 both include components such as a hydraulic pump, a hydraulic valve, an oil tank and a hydraulic cylinder. The hydraulic pump extracts the hydraulic oil in the oil tank and sends it into the hydraulic cylinder. The driving device 1 31 and the driving device 2 43 respectively drive the hot pressing plate 1 30 and the hot pressing plate 2 42 to move back and forth through the extension and contraction of the hydraulic cylinder.

The molding mold 24 includes a molding plate 1 33 and a molding plate 2 34. The width and bottom angle of the molding plate 1 33 are respectively the same as the width and concave angle of the depression 1 3. The molding plate 1 33 is located directly above the molding groove 1 32. A plurality of molding rods 35 are fixedly connected to the side of the molding plate 1 33 away from the feed roller 1 20. The cross-sectional shape of the forming rod 35 is the same as the cross-sectional shape of the ventilation groove 9, the length of the forming rod 35 is the same as the length of the ventilation groove 9, the distance between adjacent forming rods 35 is the same as the distance between adjacent ventilation grooves 9 along the width direction of the inner layer 1, the hot pressing plate 30 is made of copper material and can quickly transfer heat. The hot pressing plate 30 is electrically heated. When the inner layer 1 is conveyed between the hot pressing plate 30 and the forming plate 33, the driving device 31 drives the hot pressing plate 30 to move in the direction close to the forming plate 33, and the two sides of the breathable part 11 are hot-pressed and bent by the forming plate 33 and the hot pressing plate 30 to form a concave 3 and a convex 4 as a whole. At the same time, the hot pressing plate 30 and the hot pressing plate 2 42 hot-press and fix the fixed part 12 and the outer layer 2 and form a plurality of ventilation grooves 9 on the fixed part 12 through the support of a plurality of forming rods 35.

[0028] like Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, a groove 36 is formed on the top surface of the forming plate 1 33, and the bottom surface of the forming plate 2 34 is connected to the bottom surface of the groove 36 through a plurality of springs 37 arranged in an array. The width of the forming plate 2 34 is the same as the width of the groove 36. The forming plate 2 34 is located outside the groove 36 when not under force. The width and curvature of the forming plate 2 34 are respectively the same as the width and curvature of the concave 2 5. A plurality of piercing members 38 are fixedly connected to the bottom surface of the groove 36. The cross-sectional shape of the piercing members 38 is the same as the cross-sectional shape of the air-permeable groove 8.

When the second driving device 43 drives the second hot pressing plate 42 to move downward in the direction close to the forming mold 24 until it contacts the second forming plate 34, the plurality of springs 37 are compressed. When the second forming plate 34 moves to the point where the support bar 44 and the groove 36 are in contact, the plurality of springs 37 are compressed.
