Patterned leather production method, leather and leather products

Abstract

The invention discloses a method for making patterned leather, leather and leather products, including 100-150 parts of liquid sodium silicate, 10-50 parts of water, 10-20 parts of leveling agent, and 10-20 parts of plasticizer; the effect of the invention The slurry has good adhesion, film-forming properties and uniform fluidity, and can form a uniform effect slurry layer on the leather grain surface, which is easy to crack and wash after drying; based on the effect slurry, a pattern is also disclosed The leather manufacturing method solves the problems in the prior art that the leather grain pattern is single and the pattern shape and distribution are uncontrollable, and saves the existing leather sealing step; the pattern leather prepared by this method has a complete and clear grain surface, and the pattern is natural and unrestrained , the body is soft, plump and elastic, and the physical and chemical indicators meet the industry standards. It is a high-end, atmospheric, individual and fashionable special effect leather product, which can be used to make shoe uppers, bags, home decorations, etc., with good The application prospect is worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical fields of tanning chemistry and tanning engineering, in particular to a method for making patterned leather, leather and leather products. Background technique [0002] With the development of social economy and the improvement of living standards, people's material life is becoming more and more abundant, which not only requires leather and its products to have good natural characteristics, but also has increasingly prominent requirements for the individualization and fashion of leather and its products. As a high-grade special effect leather product, it is favored by people. [0003] There are mainly several production methods for patterned leather: [0004] One is film printing, for example, the application number is CN201510380498.3, which discloses the production process of pattern leather, which transfers the pattern on the film paper to the surface of the leather coating, and then repaints to protect the p...

Problems solved by technology

[0015] The embodiment of the present application provides an effect pulp for leather and a method for making patterned leather based on the effect pulp, which solves the problem of single grain pattern and pattern shape and distribution caused by casein isolation of crust leather in the prior art. Uncontrollable problems, and realize the effect that there is no need to seal the leather before applying the effect paste, so as to avoid affecting the combination of dyes and crust leather
