Abstract

The invention discloses a dyeing assistant and application thereof in a process of dyeing wool by adopting disperse dyes. The dyeing assistant comprises the following components in percentage by mass:30-65% of polyoxyethylene fatty alcohol ether, 5-12% of N-lauryl betaine, 1-5% of hexadecylpyridinium bromide, 1-3% of polyethylene glycol and 3-5% of chitosan. According to the dyeing assistant disclosed by the invention, the polyoxyethylene fatty alcohol ether serves as a main component, the turbidity point of the polyoxyethylene fatty alcohol ether is improved by adding the N-lauryl betaine, hexadecylpyridinium bromide and polyethylene glycol, and the solubilizing and dyeing effects of the dyeing assistant are enhanced; and by adding the chitosan, mixed micelles are deeply introduced intoa fiber network, diffusion of the dyes in the fibers is accelerated, and the dye uptake of the dyes is improved.

Description

technical field [0001] The invention relates to the technical field of dyeing with disperse dyes, in particular to a dyeing auxiliary and its application in the process of dyeing wool with disperse dyes. Background technique [0002] As we all know, the dyeing speed of dyes to fibers is not only determined by the molecular structure of dyes and fibers, but also related to the solubility of dyes in the dye bath and the degree of swelling or plasticization of fibers during dyeing. And choose appropriate auxiliaries, increase the solubility of insoluble dyes in the dye bath, can speed up the adsorption of dyes to fibers, if the auxiliaries can solubilize or plasticize fibers, it can also accelerate the diffusion of dyes in fibers speed, which can speed up the entire dyeing speed. [0003] The effect of solubilizing dyeing with additives is mainly reflected in the following four aspects: (1) increase the solubility of insoluble dyes; (2) accelerate the adsorption of dyes to the...
