[0031] like Figure 2 and Figure 3 As described in the above, the first anti-wrinkle fiber 201, the second anti-wrinkle fiber 202 and the edge strip 204 are any one of polyether elastic fiber or polyurethane elastic fiber, which have excellent elastic properties and good resilience. The two first anti-wrinkle fibers 201 are arranged up and down, and the two second anti-wrinkle fibers 202 are arranged up and down, so that the two first anti-wrinkle fibers 201 and the two second anti-wrinkle fibers 202 are arranged crosswise, so that the contact area of ​​the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 forms a cross-net, and the intersection positions of the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 are fixed to each other, so that the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 can be connected, so that the recycled polyester fabric body 1 is subjected to tension. When stretched, the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 can produce elastic deformation, thereby elastically supporting the recycled polyester fabric body 1, and after the stretching force disappears, the recycled polyester fabric body 1 can use the resilience of the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 to restore its shape, thereby avoiding wrinkles caused by the recycled polyester fabric body 1 being unable to recover due to stretching, and the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 in the cross-mesh contact area have strong resilience. At the same time, the double-layer first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 are arranged in coordination, which also strengthens the elastic support strength of the recycled polyester fabric body 1, increases the stretching range of the fabric, and further improves the rebound effect and efficiency of the recycled polyester fabric body 1.

Due to the existence of the empty groove 203, when the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 are elastically deformed, there is sufficient elastic activity space, which provides spatial support for the elastic range of the recycled polyester fabric body 1, and effectively improves the deformation range of the recycled polyester fabric body 1. Then, under the setting of the edge strip 204, the ends of the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202 are fixed to avoid bifurcation or position displacement at the ends of the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202, which effectively improves the stability and effectiveness of the use of the first anti-wrinkle fibers 201 and the second anti-wrinkle fibers 202. As mentioned above, the anti-wrinkle layer 2 is symmetrically fixed at the top and bottom ends of the recycled polyester fabric body 1, which can effectively improve the anti-wrinkle performance of the recycled polyester fabric body 1, and the anti-wrinkle layer 2 is compounded with the recycled polyester fabric body 1 by any one of hot pressing or adhesion.

The flame retardant layer 102, the antibacterial layer 103, the waterproof layer 104, the water-absorbing layer 105 and the skin-friendly layer 106 are all composited by hot pressing or bonding. The regenerated polyester fiber layer 101 includes warp yarn and weft yarn, the warp yarn is 100% regenerated polyester fiber, and the weft yarn is any one of polyester fiber, bamboo fiber, cotton fiber, modal fiber and glass fiber.
