Problems solved by technology

[0002] The tensile strength and tear strength of the PU leather produced by the existing traditional production process are much worse than the customer's requirements, and the physical properties can no longer meet the customer's requirements. The artificial leather industry is a marginal interdisciplinary subject. The introduction, grafting and reference of the leather industry are the source of innovation

Abstract

The invention relates to the field of preparation of artificial leathers, in particular to a preparation method of high-physical-property artificial leather. Accroding to the preparation method, a composite process is added on the basis of traditional PU (polyurethane) leather process, namely, a layer of special base cloth is composited after the traditional PU leather process ends so as to obtain the artificial leather with higher, more special physical property, function and texture; so that the problems of the prior art can be solved.

Description

technical field [0001] The invention relates to the field of artificial leather preparation, in particular to a method for preparing artificial leather with high physical properties. Background technique [0002] The tensile strength and tear strength of the PU leather produced by the existing traditional production process are much worse than the customer's requirements, and the physical properties can no longer meet the customer's requirements. The artificial leather industry is a marginal interdisciplinary subject. The introduction, grafting and reference of leather industry are the source of innovation. This requires our practitioners, especially R&D personnel, to constantly expand their horizons, broaden their thinking, and break through routines in order to provide more and better new products for the market and customers. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing artificial leather with high physica...
