Abstract

The invention relates to the field of dyeing assistants, in particular to a dyeing assistant for pure-cashmere products. The dyeing assistant is prepared from, by mass, 5-8 parts of carboxymethyl chitosan, 3-10 parts of sodium sulfate, 1-4 parts of linear alcohol ethoxylates, 2-3 parts of sulfonated castor oil, 10-15 parts of polyacrylamide, 10-12 parts of sodium polyacrylate, 8-10 parts of dodecyl dimethyl betaine, 2-5 parts of alkylphlhalimide, 4-6 parts of diethylenetriamine, 5-10 parts of acetic acid and 40-60 parts of water. The dyeing assistant for the pure-cashmere products and dye are added at the same time according to a certain proportion in the dyeing process, in this way, the color fastness can be effectively improved in pure-cashmere dyeing, damage to the pure-cashmere can be avoided, and the dyeing performance can be improved.
