Abstract

The invention discloses a hydrogen peroxide orientation catalytic composite additive. The additive is prepared by mixing the following raw materials in percentage by mass: 0.001-5% of copper salt, 0.001-0.01% of ferric salt, 0.001-5% of ammonia water, 0.001-5% of a chelating agent, 0.001-5% of dodecyl dimethyl benzyl ammonium chloride, 0.001-5% of fatty alcohol-polyoxyethylene ether, 0.001-5% of alkyl sodium sulfonate, 0.001-5% of sodium alkyl sulfate and 64.99-99.992% of purified water, wherein the total percentage by mass is 100%. The invention also discloses a method for carrying out pretreatment on cotton fabrics by using the additive. The method is characterized by comprising the following steps: placing cotton fibers or cotton fabrics to be treated in a pretreatment device, adding pretreatment water and keeping dyeing bath circulation; carrying out pretreatment on the cotton fibers or the cotton fabrics in the pretreatment device by using the hydrogen peroxide orientation catalytic composite additive.

Description

Technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and relates to a hydrogen peroxide positioning and catalyzing composite auxiliary agent XAT. The invention also relates to the application of the hydrogen peroxide positioning and catalyzing composite auxiliary agent XAT in the pretreatment of cotton fibers or cotton textiles. Background technique [0002] The symbiotic impurities of cotton fiber mainly include pectin substances (mainly in the form of calcium, magnesium salts and methyl esters of polygalacturonic acid and in the form of esters formed with cellulose macromolecules), nitrogen-containing substances (mainly in the form of protein) Existence), waxy substances (mainly in the form of higher fatty alcohols, higher fatty acids and their sodium salts, higher monoalcohol esters, solid and liquid hydrocarbons), ash (mainly in the form of inorganic salts), pigments and Cotton seed hulls (the main component is lignin). The pre...
