Double face leather production process capable of eliminating electrostatic interaction in double face leather product processing process

Abstract

The invention provides a double face leather production process capable of eliminating electrostatic interaction in a double face leather product processing process, which comprises the following steps of: performing water return and retanning on double face leather crust leather, and performing wool dyeing, plate dyeing and acid pickling to obtain double face leather colored leather; carrying outroll ironing and shearing on the woolen cover surface of the double face leather colored leather obtained in the previous step, then finishing, and carrying out roll ironing again to obtain a semi-finished product; and spraying an antistatic agent on the plate surface of the semi-finished product obtained in the previous step to obtain a double face leather product. The problem of electrostatic dust adsorption in the processing process is effectively solved, the durability and high-efficiency effects are remarkable, the comprehensive performance such as sanitation, attractiveness and safety of a double face leather product can be improved, and the processing difficulty of the double face leather product is reduced. The technical means is economical and environmentally friendly, the problems of adhesion of dust and scurf of a double face leather finished product and the like caused by static electricity are avoided, and meanwhile, the product has the characteristics of thinness, lightness and softness, the tearing strength reaches the standard, the hexavalent chromium content is extremely low, and the economic benefit and the environment-friendly benefit are remarkable.

Description

technical field [0001] The invention belongs to the technical field of leather treatment and processing, and relates to a leather production process capable of eliminating static electricity during the processing of wool leather products, in particular to a wool leather production process capable of eliminating static electricity during the processing of wool leather products. Background technique [0002] Leather processing has a history of thousands of years. After a long period of development, tanning has developed from a simple manual operation to an important industrial technology field. Since the early 1980s, my country's leather industry has developed by leaps and bounds, and it has become one of the most important leather and leather product production centers in the world. my country's cowhide, pigskin, sheepskin and other resources rank first in the world, and its annual output of light leather ranks first in the world, accounting for more than 20% of the world's t...

AI Technical Summary

Problems solved by technology

[0005] Frictional electricity generation is a well-known natural phenomenon. Although static electricity is beneficial to leather processing in some aspects, such as electrostatic flocking, etc.; but more is the inconvenience brought to production and processing and the difference in product wearing comfort, such as Due to the existence of static electricity during the processing of fur leather products, the dust in the air or the grinding dust during the processing will easily be adsorbed on the surface of the fur, and it is difficult to remove it with a dust collector. These problems caused by static electricity will greatly increase the difficulty of processing fur leather products, and more and more fur leather products on the market are based on hygiene, comfort and safety. Therefore, anti-static Functionality places increasing demands on

At present, the main technical means for the static electricity problem of fur leather products in the industry is to carry out various technological treatments in the finishing stage, such as improving the performance of the dust collector, etc., but how to completely solve the static electricity problem and achieve an extremely comfortable wool surface Hand feel and safety performance, this question is pending

Due to the insufficient antistatic treatment of the rough surface, there are problems such as large damage to the rough surface, poor aesthetics of the rough surface, difficult to control large-scale production, poor stability, unsafe and other problems, and the antistatic durability is poor. After many production verifications, even if the production The control is very careful, and the fur leather products are processed to finished products using the existing technology, but there are still a large number of products that have static electricity problems during use
