Activated dye low-alkaline dyeing method for black regenerated cellulose fiber cheese

Abstract

The invention relates to the field of printing and dyeing, particularly to an activated dye low-alkaline dyeing method for a black regenerated cellulose fiber cheese. The method comprises the steps of pretreatment, dyeing, fixing and follow-up treatment; in addition, low alkaline is adopted in the dyeing and fixing processes and the working procedures are reduced. Therefore, the dyeing temperature of the regenerated cellulose fiber is reduced; the alkaline dosage for dyeing the regenerated cellulose fiber is lowered; the method is simple to operate, short in technical duration, and low in alkaline content in the dyeing waste water, can reduce the dosage of glacial acetic acid for neutralization in the follow-up procedure, lowers washing water volume, saves energy and reduces emission, improves the color fastness of the cheese, and lowers the dyeing cost.

Description

technical field

[0001] The invention relates to the field of printing and dyeing, in particular to a method for low-alkali dyeing of black regenerated cellulose fiber cheese with reactive dyes. Background technique

[0002] In the 21st century, my country's textile industry has entered a period of rapid development, and the output of regenerated cellulose fiber has reached 70% of the world's output. Due to the reduction of cultivated land and the depletion of oil resources, the output of natural fibers and synthetic fibers will be increasingly affected. More and more constraints; people re-understand and explore the value of regenerated cellulose fiber while paying attention to the environmental protection performance in the process of textile consumption. Regenerated cellulose fiber has excellent properties such as good hygroscopicity, strong air permeability, good dyeing performance, comfortable wearing, easy textile processing, and biodegradability. Now the application of ...
