Abstract

The invention provides a self-emulsifying softener and a preparation method thereof, the self-emulsifying softener of the present invention is composed of formula (I), formula (II) and formula (III), wherein, m is an integer of 5-40; n is an integer from 1‑100; R 1 for H or CH 3 ; 2 for COOH or CH 2 CH(COOH) 2 . The self-emulsifying softener prepared by the invention does not contain solvent, has excellent application stability such as hand feeling, alkali resistance, high temperature resistance and electrolyte resistance, and is easy to control in production.

Description

A kind of self-emulsifying softener and preparation method thereof technical field The present invention relates to a kind of softener and preparation method thereof, particularly a kind of self-emulsifying softener and preparation method thereof Law. Background technique With the improvement of people's quality of life, the more comfortable and functional textiles are pursued, and the general textile printing and dyeing products After a series of chemical, physical and mechanical tension processing such as pretreatment, dyeing, etc., it will cause hand feeling problems such as hardening and stiffness. This will seriously affect the wearing performance of textiles. Therefore, softeners are often used for post-finishing to meet the requirements The desired feel. Silicone softening agent is a class of softening agent with wide application, good performance and outstanding effect on textiles. The particles are adsorbed on the fibers, which can greatly reduce the fri...
