Currently, in the preparation process of shaping clothes on the market, the main application is polyurethane type glue film or glue net, but the glue of the type has some defects, such as:
1. the specific gravity of the polyurethane is higher and is 1.2g/cm3The plastic cement is made of a higher material, and the polyurethane with higher gram weight can influence the hand feeling;
2. the general yellowing resistance of polyurethane is poor, the yellowing time is mainly prolonged by adding a UV (ultraviolet) auxiliary agent in the industry at present, but for some white or light-colored fabrics, the yellowing time is only delayed by adding the UV auxiliary agent, and the yellowing resistance of the fabrics cannot be improved;
3. the polyurethane net film fiber is in a non-woven fabric shape in a random way, so the tensile strength and the recovery rate are greatly reduced, and the effect required by shaping clothes can not be achieved.
The above problems may cause the texture of the shaping clothes to be decreased, and the shaping clothes are not durable, so that the ideal using effect of the shaping clothes is difficult to achieve, and thus the requirements of consumers cannot be met.
