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 producti

Example Embodiment

[0012] Embodiment 1: Concrete operating steps are as follows:

[0013] (1) Add the wool product to be processed in a ratio of 20:1 in a bath ratio, place it in a 3000-liter steam heating pool, and add 1% of the total wool product as a decolorizing agent to be NH 4 OH and 0.5% decolorizer H 2 O 2 , heat up to 45-50 ℃, after preheating at this temperature for 60 minutes, move all wool products into the second steam heating pool.

[0014] (2) Add 2.5% bleaching block or bleaching powder of the total amount of wool products in the second steam heating pool, control the amount of water added with a bath ratio of 20:1, and heat at a constant temperature of 60 ° C for 60 minutes as the control end point. At this time, the colored wool fibers have been It is reduced to colorless or light-colored leuco fibers, and then all the wool products in the second steam heating pool are moved into the third heat bath heating pool.

[0015] (3) Add 1800L of water, 40kg of washing powder, 0.5kg...

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...
