Abstract

The hydrogen peroxide positioning catalytic composite auxiliary agent disclosed by the invention is prepared by mixing the following raw materials according to mass percentage: 0.001% to 5% of copper salt, 0.001% to 0.01% of iron salt, 0.001% to 5% of ammonia water, and 0.001% of chelating agent %~5%, dodecyl dimethyl benzyl ammonium chloride 0.001%~5%, fatty alcohol polyoxyethylene ether 0.001%~5%, sodium alkylsulfonate 0.001%~5%, alkyl sulfate 0.001% to 5% sodium, 64.99% to 99.992% pure water, the total content of the above components is 100%; the invention also discloses a method for pretreatment of cotton textiles by using the above-mentioned auxiliary agents, and the cotton fibers or cotton textiles to be treated are Put it into the pre-treatment equipment, and add pre-treatment water to keep the dyeing bath circulating; use hydrogen peroxide to position and catalyze the composite auxiliary to pre-treat the cotton fibers or cotton textiles in the pre-treatment equipment.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and relates to a hydrogen peroxide localized catalytic composite auxiliary agent XAT, and also relates to the application of the hydrogen peroxide localized catalytic composite auxiliary agent XAT in the pretreatment of cotton fibers or cotton textiles. Background technique [0002] Cotton fiber symbiotic impurities mainly include pectin substances (mainly in the form of calcium, magnesium salts and methyl esters of polygalacturonic acid and esters formed with cellulose macromolecules), nitrogen-containing substances (mainly in the form of protein exist), waxy substances (mainly in the form of higher fatty alcohols, higher fatty acids and their sodium salts, esters of higher monohydric alcohols, and solid and liquid hydrocarbons), ash (mainly in the form of inorganic salts), pigments and Cottonseed hulls (mainly lignin). The existence of these impurities will have adverse ef...
