Abstract

The invention relates to a textile hydrogen peroxide bleaching stabilizer, comprising the following components: chelating agent, surfactant, magnesium inorganic salt, sodium silicate, scale inhibitionand dispersion agent and water. The scale inhibition and dispersion agent is polyepoxysuccinic acid or sodium salt thereof and has good scale inhibiting dispersing property to silicon so that silicate scale can not deposit and adhere to the surface of fabric; the bleached product has ideal whiteness and no harsh and hard handfeel and can not pollute the inner wall of mechanical equipments.

Description

technical field [0001] The invention relates to a pretreatment auxiliary agent for textiles, in particular to an oxygen bleaching stabilizer used in the hydrogen peroxide bleaching process of textiles. Background technique [0002] In the process of bleaching fabrics with hydrogen peroxide, the decomposition reaction of hydrogen peroxide is used to complete the bleaching effect on fabrics under the condition of high temperature and strong alkali. However, in the hydrogen peroxide bleaching working solution, due to the presence of free metal ions, such as Cu 2+ , Fe 2+ , Mn 2+ 、Cr 3+ Etc., a certain amount of tiny solid particles, coupled with the effects of high temperature and strong alkali, will inevitably have a severe catalytic effect on the decomposition reaction of hydrogen peroxide, causing the hydrogen peroxide to undergo an excessively fast and ineffective decomposition reaction. This not only wastes raw materials and increases production costs, but also reduces...
