Abstract

The invention relates to a method for preparing nano-titanium dioxide modified color fixing agent emulsion and aims to overcome the defect that color fixing emulsion is poor in ultraviolet resistance. According to the method, the nano-titanium dioxide modified color fixing agent emulsion is prepared from modified nano-titanium dioxide dispersion liquid, a cationic monomer, an organic silicon monomer, an emulsifier, an initiator and deionized water in a nuclear-shell emulsion polymerization mode. The method is simple and convenient in process, simple to control and stable in polymerization system, and by adjusting the proportions of monomer components of a core layer and a shell layer, nano-titanium dioxide, the cationic monomer and the organic silicon monomer are differently distributed, and thus a purpose of modifying the color fixing agent emulsion is achieved.

Description

technical field [0001] The invention relates to a preparation method of nano-titanium dioxide-modified color-fixing agent emulsion, and belongs to the field of polymer preparation. Background technique [0002] Although some dyes can dye brighter colors, due to the water-soluble groups on the dyes, the wet fastness is not good, and the fading and staining are serious. If it is stained on white or other colored fibers, it will cause staining and color matching, such as direct dyes and acid dyes, which are prone to such problems. In addition, although reactive dyes can form covalent bonds with cellulose fibers, if there are hydrolyzed dyes or insufficient soaping of unbonded dyes during dyeing, the wet fastness will also be reduced; Reactive dyes that have formed covalent bonds may also break bonds and decompose under acidic or alkaline conditions, as well as problems such as insufficient color fastness to chlorine, perspiration fastness, and light fastness. In order to impr...
