Textile oxygen bleaching stabilizer

Abstract

The invention relates to a textile oxygen bleaching stabilizer, and belongs to the technical field of textile auxiliaries. The stabilizer comprises the following components by weight: 8-10 parts of tartaric acid, 2-5 parts of polymalic acid, 6-8 parts of polyacrylamide, 20-40 parts of a chelating agent, 2-5 parts of a surfactant and 60-80 parts of water. The textile oxygen bleaching stabilizer provided by the invention has strong pigment adsorption effect and good bleaching effect, and can effectively prevent deposition and adhesion of silicon scale on the fabric surface, and the bleached textile does not gain rough or hard hand feel; at the same time, the stabilizer can effectively control the decomposition rate of hydrogen peroxide, and effectively avoid local holes on fiber and damage to the fiber.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a textile oxygen bleaching stabilizer. Background technique [0002] h 2 o 2 It is a classic chemical product. Hydrogen peroxide bleach is widely used in the bleaching process of cellulose fibers and other fibers because of its good stability, no corrosion of equipment, and no pollution. It is an excellent bleaching agent, and the product whiteness It has good stability and no pollution to the environment, so it is a promising bleaching agent. During the bleaching process, H 2 o 2 The decomposition of is often uncontrolled, resulting in H 2 o 2 There are problems such as poor whiteness, decrease in fiber strength, and holes in the bleached cloth. In order to decompose hydrogen peroxide evenly and effectively during the bleaching process and avoid severe damage to the fabric, a certain amount of stabilizer must be added to the bleaching solution, tha...

AI Technical Summary

Problems solved by technology

[0003] Oxygen bleach stabilizer, also known as hydrogen peroxide stabilizer, is mainly silicon-based oxygen bleach stabilizer on the market at present, and its main component is sodium silicate, which has obvious pigment absorption effect and outstanding bleaching effect, but it is prone to silica scale and silica scale deposition On fabrics, causing fabrics to be rough and stiff, making it difficult to rinse

Therefore, at present, R&D personnel are mainly researching and developing non-silicon oxygen bleach stabilizers. Although some non-silicon oxygen bleach stabilizers appear on the market, they have poor ability to absorb pigments, and the whiteness of products after bleaching is low.
