Abstract

The invention discloses a dyeing auxiliary and an application thereof to dyeing assistance of disperse dyes. The dyeing auxiliary comprises following components in percentage by mass: 40%-68% of polyoxyethylene aliphatic alcohol ether, 2%-4% of polyoxyethylene stearate, 5%-8% of triethylene glycol monobutyl ether, 5%-12% of N-alkyl betaine, 6%-10% of polyamide-polyamine-epichlorohydrin and 3%-5% of chitosan. According to the dyeing auxiliary, polyoxyethylene aliphatic alcohol ether is taken as a main component, polyoxyethylene stearate is added to realize compounding synergistic interaction with polyoxyethylene aliphatic alcohol ether, and therefore, the solubilizing dyeing effect of the dyeing auxiliary is improved; the dyes are promoted to be more powerfully combined with fibers with addition of triethylene glycol monobutyl ether, cloud point of polyoxyethylene aliphatic alcohol ether is increased with addition of N-alkyl betaine, contact probability of the dyes and the fibers is increased with addition of polyamide-polyamine-epichlorohydrin, diffusion rate of the dyes in the fibers is increased with addition of chitosan, and dye uptake of the dyes is increased.

Description

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