Abstract

The invention discloses a dyeing auxiliary for disperse dye and application thereof in assistance for disperse dye in the process of dyeing wool. The dyeing auxiliary is prepared from the following components in percentage: 40-60 percent of polyoxyethylene fatty alcohol ether, 5-8 percent of triethylene glycol momobutyl ether, 3-7 percent of octadecyl betaine, 2-4 percent of hexadecylpyridinium bromide, 6-8 percent of polyamide polyamine epichlorohydrine, 2-4 percent of chitosan and 3-9 percent of poloxamer. According to the dyeing auxiliary, polyoxyethylene fatty alcohol ether is used as a main ingredient, dye and fibers can be effectively combined by adding triethylene glycol momobutyl ether, the cloud point of polyoxyethylene fatty alcohol ether is improved by adding octadecyl betaine and hexadecylpyridinium bromide, and the solubilizing and dyeing effect of the dyeing auxiliary can be reinforced; and the contact between dye and fibers can be prolonged by adding the polyamide polyamine epichlorohydrine, the dispersing speed of dye in fibers can be accelerated by adding chitosan, and the dyeing percentage of dye can be increased.

Description

technical field [0001] The invention relates to the technical field of disperse dye dyeing, in particular to a disperse dye dyeing auxiliary and its application in the process of assisting disperse dyes to dye wool. 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...
