发明名称 Method for making artificial leather with superficial texture
摘要 Disclosed is a method for making artificial leather with superficial texture. In the method, a substrate is coated, in a non-overall manner, with a wet polyurethane resin. After curing, there is provided a polyurethane resin coated on releasing paper. Thus, a semi-product is made. Texture of the releasing paper is transferred to a surface of the semi-product. Then, the semi-product with the texture on the surface is coated with a layer of a chemical. A machine is used to heat and flatten the surface of the semi-product. Finally, the semi-product is physically finished by forces so that the surface of the final product is formed with texture like that of real leather.
