Production method of simulated crystallized leather

Abstract

The invention provides a production method of simulated crystallized leather. The production method comprises the steps of stretching a leather blank, drying the leather blank, smearing the leather blank, softening the leather blank, toggling the leather blank, spraying water, slightly embossing, carrying out secondary toggling, polishing and coating. The coating fluid used for coating the leather blank in the drying and smearing step contains 500+/-2 parts of water, 50+/-2 parts of adhesion agent, 50+/-2 parts of resin, 100+/-2 parts of effect wax, 20+/-2 parts of coating cream and 30+/-2 parts of hand feeling agent, and the consumption of the coating fluid for smearing the leather blank is as follows: the consumption is 25 to 30 grams per square inches of the leather blank. By adopting the drying and smearing step, the leather blank contains more water, so that a film cannot be immediately formed, the adhesion agent can be effectively permeated into a particle surface layer of the skin, the dried smearing property is not obvious, the shielding effect is good, the natural attribute of the leather can be maintained, and the color is bright.

Description

technical field [0001] The invention relates to a method for making leather, in particular to a method for making simulated crystal leather. Background technique [0002] As we all know, untreated leather generally has a lot of defects, such as scratches, pinholes, rotten surfaces, blood tendons or large grains, etc., which seriously affect the productivity of leather. In traditional production, dyeing or back cover is generally used for processing, which easily distorts the leather and affects its natural attributes and use grades. Moreover, this type of processing has complicated procedures and low production efficiency, which indirectly increases the use of chemical raw materials and labor costs. Increased production costs. [0003] For the above problems, the applicant has carried out in-depth research, and this case has been produced. Contents of the invention [0004] The purpose of the present invention is to provide a method for making simulated crystallized leat...
