Decolorizing reutilization process for wool product

Abstract

The related decoloring and recycling scheme for dyed wool products comprises: (1) putting the wool products into the first steam-heating pond, adding decolourant to decolor; (2) for a while, moving the products into the second heating pond, adding decolourant again; (3) reducing the dyed fiber into the leuco or light colored, then moving to the third heating pond; adding cleanser, fluorescent powder and brightener to hold for some time and dewater. This invention supplies a gap with less investment and well security, and brings great social and economic benefits.

Description

1. Technical field: [0001] The invention relates to a chemical process method, in particular to a technical process for decolorizing and reusing wool products for decolorization and reuse of dyed wool products. 2. Background technology: [0002] In the wool fiber product processing industry, a large-scale wool product processing system has been formed in China, so that wool fiber has been fully applied in the woolen yarn and woolen printing and dyeing industries. The total amount of domestically processed wool fiber products is less than 80 million tons, which still cannot meet the requirements of 200 million tons for domestic and foreign trade exports. To increase the total output of wool fiber products, we must expand the source of raw wool, vigorously develop sheep and animal husbandry, and in the existing wool On the basis of fiber and product production, the reduction of consumption should be realized. In my country, the research on improving the utilization rate of wool...

Problems solved by technology

The total amount of domestically processed wool fiber products is less than 80 million tons, which still cannot meet the requirements of 200 million tons for domestic and foreign trade exports. To increase the total output of wool fiber products, we must expand the source of raw wool, vigorously develop sheep and animal husbandry, and in the existing wool On the basis of fiber and product production, the reduction of consumption should be realized. In my country, the research on improving the utilization rate of wool fiber, especially the research on the complete decolorization of dyed wool products started relatively late. Although a few domestic companies have started preliminary research, but Due to the different production routes adopted, there are technical problems to varying degrees
