Abstract

The invention relates to a textile hydrogen peroxide bleaching stabilizer, comprising the following components: chelating agent, surfactant, magnesium inorganic salt, sodium silicate, scale inhibition and 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

Textile hydrogen peroxide bleaching stabilizer
Technical field
What the present invention relates to is the textiles pre-treatment auxiliary agent, and what be specifically related to is textiles used hydrogen peroxide bleaching stabilizer in the hydrogen peroxide bleaching process.
Background technology
In hydrogen peroxide bleaching fabric process, be under high temperature highly basic condition, to utilize the decomposition reaction of hydrogen peroxide to finish discoloration to fabric.But in the hydrogen peroxide bleaching working solution, owing to have free metal ion, as Cu 2+, Fe 2+, Mn 2+, Cr 3+Deng, a certain amount of small solid particle, add the effect of factors such as high temperature highly basic, will certainly produce violent catalytic action to the decomposition reaction of hydrogen peroxide, make hydrogen peroxide that too fast invalid decomposition reaction take place.This not only wastes raw material, and has increased production cost, but also can reduce the bleaching whiteness, even may cause fabric local broken hole to occur, falls strong equivalent damage phenomenon.In the bleaching liquid bleaching process, must add a certain amount of hydrogen peroxide bleaching stabilizer for this reason, effectively control the resolution ratio of hydrogen peroxide, cut the waste, improve the bleaching whiteness, guarantee the fabric feeling ideal, avoid fabric damage.Common hydrogen peroxide bleaching stabilizer by its whether siliceous composition can be divided into two kinds of silicon class and non-silicon classes.Silicon class hydrogen peroxide bleaching stabilizer, main component is a sodium metasilicate, is characterized in that the adsorpting pigment effect is obvious, and bleaching effect is outstanding, but this type of hydrogen peroxide bleaching stabilizer has following shortcoming: the one, be prone to the silicon dirt, and silicon dirt easily deposition attaches on fabric, even strengthen rinsing, also is difficult to clean, can cause thus that the bleach product feel is coarse hardens, the 2nd, its strong basicity resisting is relatively poor, and the 3rd, the silicon dirt can pollute the machinery inwall, cleans difficulty.Non-silicon class hydrogen peroxide bleaching stabilizer, its principal component mostly is the organic acid chelating agent with sequestering power greatly, characteristics are to become stable water soluble chelate compound with metal ion-chelant, can effectively alleviate or stop the too fast violent catalyticing decomposition action of free metal ion to hydrogen peroxide, can effectively control the decomposing hydrogen dioxide solution rate, bleach product does not have the coarse feel of hardening, no fibre damage.But this type of hydrogen peroxide bleaching stabilizer also has following defective: the one, and the adsorpting pigment ability, bleaching back product whiteness is lower, the 2nd, other impurity beyond can not chelated metal ions, and the excessive invalid decomposition that these impurity also can the catalysis hydrogen peroxide with catalytic decomposition hydrogen peroxide.
Summary of the invention
The objective of the invention is to improve at the shortcoming deficiency of siliceous class hydrogen peroxide bleaching stabilizer, provide a kind of production easy, this one-tenth is low, degree of bleaching is good, can effectively stop the silicon dirt deposition to stick to fabric face, feel does not have the coarse sense of hardening, and can effectively control decomposing hydrogen dioxide solution speed, the textile hydrogen peroxide bleaching stabilizer of no fibre damage.
Main technical schemes of the present invention is in the basic recipe of the siliceous class hydrogen peroxide bleaching stabilizer of tradition, add dirt dispersion agent poly-epoxy succinic acid or its sodium salt, reach peptizaiton, the silicon dirt can be dispersed in the bleaching working solution, and no longer deposition attaches at fabric face the silicon dirt, can not pollute the machinery inwall more yet, bleaching back fabric can be cleaned fabric, bleach product whiteness ideal by normal washing operation, the no coarse feel of hardening, no fibre damage.
Hydrogen peroxide bleaching stabilizer of the present invention includes chelating agent, surfactant, magnesium inorganic salts, sodium metasilicate and water to be formed, and it is characterized in that also containing dirt dispersion agent poly-epoxy succinic acid or its sodium salt.
Raw material is formed weight ratio:
Dirt dispersion agent 2-5, chelating agent 10-15, surfactant 2-5, magnesium inorganic salts 1-5, sodium metasilicate 5-10, water 63-70.
The present invention selects for use poly-epoxy succinic acid or its sodium salt as dirt dispersion agent, because this base polymer has good scale inhibition peptizaiton to the silicon dirt, attaches at fabric face bleach product whiteness ideal so the silicon dirt is no longer deposited, the no coarse feel of hardening, and can not pollute the machinery inwall yet.
The present invention on the basis of the above, chelating agent is selected phytic acid or diethylenetriamine five methene sodium ascorbyl phosphates for use, its sequestering power is strong, make free metal ion be chelated into the water soluble chelate compound of anti-highly basic, Heat stability is good, thereby stoped the violent catalyticing decomposition action of free metal ion to hydrogen peroxide, effectively avoid the local broken hole of fiber or fallen strong damage, no fiber damaged phenomenon.
Surfactant is selected octadecyl polyoxyethylene ether or polyoxyethylene nonylphenol ether for use, and raising hydrogen peroxide bleaching stabilizer stable and uniform under the condition of high temperature highly basic is scattered in the ability in the bleaching working solution, guarantees that fabric reaches best bleaching effect.
The specific embodiment
