Production process of super waterproof leather

Abstract

The invention discloses a production process of super waterproof leather. Backwater, retanning, neutralization, filling, dyeing, stuffing, fixing, skin layer and resin layer combination and the like are performed on two-layer leather. The process comprises a plurality of waterproof processing steps of the leather, and a skin layer and a resin layer which have good air permeability are combined with the surface of a base material of the two-layer leather, so that the texture of the leather is guaranteed, the effect of increasing the physical strength of the leather is achieved, therefore, the leather which is produced by using the process has the advantages of super waterproof performance and high air permeability, and the texture of the leather is not destroyed.

Description

technical field [0001] The invention relates to the technical field of leather making, in particular to a production process of super waterproof leather. Background technique [0002] In recent years, the research on cowhide two-layer leather has gradually deepened, but because ordinary leather is not water-resistant, the durability, suitability and universality of leather use are all restricted, especially when it is raining, walking on muddy roads or drinking and other dirt. When the leather shoes, clothing and other items made of cowhide split leather that have not been specially treated are stained, the leather products are in a very embarrassing situation, and it is difficult to reprocess and restore them as new. However, after the leather is treated with a common waterproof process, the performance of the leather such as breathability and moisture absorption is affected, and the waterproof effect is not satisfactory. As people's requirements for leather performance ar...

[0002] In recent years, the research on cowhide two-layer leather has gradually deepened, but because ordinary leather is not water-resistant, the durability, suitability and universality of leather use are all restricted, especially when it is raining, walking on muddy roads or drinking and other dirt. When the leather shoes, clothing and other items made of cowhide split leather that have not been specially treated are stained, the leather products will be in a very embarrassing situation, and it is difficult to reprocess and restore them as new

However, after the leather is treated with ordinary waterproofing process, the breathability and moisture absorption of the leather will be affected, and the waterproof effect is not satisfactory.
