Abstract

The invention relates to a tanning agent for a chinchilla skin and a tanning process of the chinchilla skin. The tanning agent is prepared from ammonium sulfate, diisocyanate, urea-formaldehyde resin, sodium phthalate, dibutyl itaconate, dicarboxylic-ethylamine, 2-oxopyrrolidine, carboxybenzaldehyde, dibutylamine, fatty aldehyde and cis-butenedioic acid. The tanning process comprises a step of sequentially carrying out processes of water immersion, fleshing, softening, tanning and airing on the chinchilla skin. According to the tanning agent provided by the invention, a good tanning effect pointedly on the chinchilla skin is achieved; by adopting the tanning agent, the processes of tanning the chinchilla skin can be effectively simplified; the processes of water immersion, fleshing, softening, tanning and airing of the chinchilla skin are only carried out so as to obtain chinchilla leather; the tanning process has an effect of eliminating lipid of the chinchilla skin, and the tanning process can be effectively simplified, the tanning efficiency is also effectively promoted, and the production cost is effectively reduced; moreover, the prepared chinchilla leather has good properties of soft and delicate handfeel, abrasion resistance, good elasticity and the like.

Description

technical field [0001] The invention relates to a tanning agent and a tanning process thereof, in particular to a tanning agent especially suitable for squirrel skin and the tanning process of the squirrel skin. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. [0003] The current leather tanning process is relatively complicated. For example, the Chinese invention patent with application number 201310725180.5 provides a goatskin synthetic tanning process. Meat → secondary degreasing → pickling → softening → tanning → neutralization → drying with water → regain moisture and shovel until soft. The tanning process requires multiple processes of immersion in water, degreas...
