Abstract

The invention discloses chlorine-free bleaching powder for textile materials, made from 15-30 parts of rare earth, 10-28 parts of hydrogen peroxide, 5-15 parts of sodium percarbonate, 5-10 parts of sodium percarbonate, 2-5 parts of sodium sulfate, 4-9 parts of primary alcohol ethoxylate, 1-7 parts of a sodium salt of maleic anhydride-acrylic acid copolymer, 2-7 parts of sodium hydroxyethyl sulfonate, 2-7 parts of a brightener, 5-12 parts of an activator, 0.5-3.5 parts of a catalyst, and 1.5-5.5 parts of a stabilizer. The chlorine-free bleaching agent for textile materials and a preparation method thereof are provided herein; the bleaching agent is friendly to equipment and personnel, and is suitable for bleaching in an acid environment; the bleaching steps are simple and quick, and a textile material bleached is better for dyeing.

Description

technical field [0001] The invention belongs to the field of textile processing, and in particular relates to a non-chlorine bleaching agent for textile materials and a preparation method thereof. Background technique [0002] Most of the textile materials have a slight base color, that is, cotton-like yellow, and when dyeing light colors or some bright colors, they need to be bleached first. Textile materials usually have poor alkali resistance, and the whiteness effect of traditional oxygen bleaching is not good. Currently, chlorine bleaching is used, that is, sub-bleaching process. The working solution of chlorine bleaching not only causes great damage to equipment and personnel, but also forms a difficult-to-degrade organic halide AOX, which can interact with human proteins or nucleic acids and cause hereditary lesions. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a chlorine...
