Abstract

The invention relates to the field of textile dyeing and finishing auxiliaries, in particular to a preparation method of an efficient deepening type composite deepening agent. The preparation method has the advantages that urea resin and urea are used to perform double modification on methyl trichlorosilane to allow amino-modified organic silicon to have a good deepening effect so as to increase the deepening effect of the deepening agent; two kinds of emulsions formed by trifluoroethyl methacrylate and isophorone diisocyanate are added to lower reflected light quantity of fabric, and the apparent depth of substances such as dyed fabric is increased; the organic silicon has high hydrophobicity and low refractive index, so that the refractive index of the two emulsions above is reduced, the apparent depth of the substances such as the dyed fabric is increased, the deepening effect of the deepening agent is further increased, and the prepared deepening agent is promising in application prospect.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing auxiliaries, in particular to a preparation method of a high-efficiency darkening compound darkening agent. Background technique [0002] With the improvement of living standards, people's requirements for textiles are getting higher and higher. Synthetic fibers have been widely used in recent years because of their high strength. Among them, polyester fibers are often used to replace natural fibers such as silk due to their cost advantages. But a big disadvantage of polyester fiber is that it is poor in dyeing dark color, especially black and other dark fabrics. Boundless visual effects. The problem of deep staining has become more and more serious. The emergence of the darkening agent is to solve this problem. It is an auxiliary agent that can improve the dyeing depth of disperse dyes on polyester fabrics. The excellent performance of the darkening agent directly affects the dark c...
