Abstract

A preparation method of environment-friendly ironing-free antibacterial finishing agent for wool fabrics belongs to the field of textile finishing agents and includes the steps of: 1) performing a reaction to chitin with diluted hydrochloric acid (15 wt%); 2) adding octyl phenol polyoxyethylene ether, polyethylene glycol and phthalic anhydride, and increasing temperature and performing the reaction continuously; 3) crushing fructus nelumbinis and placing the fructus nelumbinis in an alcohol water solution (60 wt%) to perform stirring extraction, and then performing centrifugal separation and collecting a supernatant; 4) adding the supernatant to the mixture after the heating reaction, adding ironing-free resin FR-E and tartaric acid, and stirring the components in a stirring machine to prepare the environment-friendly ironing-free antibacterial finishing agent. The preparation method employs easy-to-purchase, safe and environment-friendly raw materials, is simple and is low in energy consumption. A fabric processed with the finishing agent has excellent ironing-free and antibacterial performances. The product is an environment-friendly finishing agent which has excellent promotingvalue.

Description

technical field [0001] The invention belongs to the field of textile finishing agents, and in particular relates to a preparation method of an environment-friendly non-ironing antibacterial finishing agent for wool fabrics. Background technique [0002] Wool fabric has good elasticity, strong moisture absorption, good warmth retention, not easy to stain, soft luster, excellent dyeing and unique shrinkage. It is usually made into a sweater or wool coat to keep out the cold, but wool coats are used in clothing It is extremely prone to wrinkling during the washing and washing process, requiring high-frequency ironing, which is not only cumbersome, but also reduces the service life of the coat. [0003] In an ideal climate between fabric and fabric, bacteria can multiply unhindered, causing skin infections, leading to poor sanitation and the spread and spread of disease. The widely used silicone quaternary ammonium salts have good antimicrobial effect, and can effectively inhib...
