Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 As shown, the present invention comprises a base cloth 1 of a polyester space-changing yarn (air textured yarn) fabric, and the upper and lower surfaces of the base cloth 1 are coated with a thin layer of low-modulus polyurethane adhesive layer 2 with a relatively low degree of polymerization. A thin layer of high modulus polyurethane adhesive layer 3 is coated on the surface of the upper and lower low modulus polyurethane adhesive layers 2 .
[0022] In the above-mentioned embodiment, the upper and lower surfaces of the fabric base cloth 1 are equally divided into two coatings, and the low-modulus polyurethane adhesive layer 2 coated for the first time is a primer. As an adhesive layer, its thickness is different according to the structure of the base cloth. , the dry weight gain of the low modulus polyurethane adhesive used ...
