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.

Description

technical field [0001] The invention relates to the field of dyeing auxiliaries, in particular to a dyeing auxiliaries for pure cashmere products. Background technique [0002] Cashmere is a kind of fine hair from the root of cashmere goats that is close to the surface of the skin. It is an animal fiber with excellent quality.

Making an ordinary cashmere sweater shows that cashmere is also a precious animal fiber. The preciousness of cashmere comes not only from its preciousness, but also from the fact that the textiles made of it have good hygroscopicity. When worn close to the skin, it can automatically absorb moisture under the changing external climate, which has a relatively It has a good perspiration effect, and can also quickly and automatically adjust with the human skin to a temperature t...
