Abstract

The invention relates to an environment-friendly stabilizer for hydrogen peroxide bleaching of cotton fabrics. The stabilizer is formed by compounding 10%-15% of EthyDiaminedhephen Acetic-Na, 0.1%-0.5% of polyacrylamide, 5%-10% of alcohol amine, 5%-10% of boric acid, 2%-10% of sodium citrate, 2%-5% of magnesium inorganic salt, 3%-5% of a dispersant, 3%-10% of fatty alcohol-polyoxyethylene ether and distilled water. According to the invention, O atoms and N atoms with strong negativity in alcohol amine and [HO2.] free radicals formed during decomposition of hydrogen peroxide form hydrogen bonds, the decomposition of hydrogen peroxide is effectively controlled, and holes generated by local brittle damage of fibers are eliminated. According to the invention, no silica scale is generated during application of the stabilizer without silicate, and thus a bleached fabric is good in hand feeling; as the stabilizer is free of phosphorous substances, environment pollution is avoided, and the stabilizer has environment-friendly effect.

Description

technical field [0001] The invention belongs to the technical field of pretreatment application of textile printing and dyeing, and relates to an environment-friendly oxygen bleaching stabilizing assistant for cotton fabrics. Background technique [0002] Cotton fiber has the advantages of good hygroscopicity, excellent wearing performance and easy dyeing, making cotton fiber the most important natural textile raw material. However, natural cotton fibers contain a lot of impurities, and some of the pigments not only reduce the white appearance of cotton fibers, but also affect the dyeing effect. These pigments need to go through a bleaching process to remove them, so that the cotton fibers can achieve the desired whiteness. The bleaching process includes chlorine bleaching process and oxygen bleaching process. Sodium hypochlorite is the most widely used bleaching agent in chlorine bleaching process. Sodium hypochlorite is irritating and emits toxic gas when it encounters ac...
