Abstract

The invention discloses an organic silicon softening and deepening agent, a preparation method thereof and an emulsion thereof, and relates to the technical field of fabric deepening agent technologies. The organic silicon softening and deepening agent comprises the following components in parts by mass: 700-800 parts of piperazinyl silicone oil, 38-46 parts of polyurethane prepolymer and 150-180parts of solvent. The organic silicon softening and deepening agent has a good deepening effect, and can endow finished fabric with the characteristics of softness and fluffy hand feeling.

Description

technical field [0001] The invention relates to the technical field of fabric darkening agents, in particular to a silicone softening darkening agent, a preparation method thereof and an emulsion thereof. Background technique [0002] In recent years, environmental protection requirements have become more and more stringent, the price of dyes has fluctuated greatly, and the production pressure of printing and dyeing factories is high. In order to alleviate this problem, many printing and dyeing factories now carry out darkening treatment on fabrics after dyeing, so as to achieve the purpose of reducing the use of dyes; An auxiliary agent used for dyeing depth, the excellent performance of the darkening agent directly affects the dyeing depth of polyester fibers and cellulose fibers. [0003] Now mainly used are polyacrylate type, polyurethane type, silicone type darkening agent. For example, the invention patent with the Chinese application number 201210419746.7 discloses ...
