Problems solved by technology

However, when using sodium dichloroisocyanurate alone as a bleaching agent / fading agent, because it releases active chlorine faster, it is not easy to control during operation, and cannot achieve the required fading effect for production, which is not conducive to subsequent re-use. Dyeing treatment

Embodiment 1

[0013] (1) the weight percent that chooses discoloration agent composition is composed of:

[0014] Sodium dichloroisocyanurate: 90%

[0015] Anhydrous sodium metasilicate: 10%

[0016] (2) The above-mentioned components are mixed according to conventional methods to prepare a decolorizing agent composition.

[0017] (3) 1Kg of decolorizing agent composition was added to 300Kg of water, and under the condition of pH 7, 40Kg of blue-green jacquard cloth was put into the bath, stirred, heated, and soaked. The process conditions and fading effects are shown in Table 1.

Embodiment 2

[0019] Add 1Kg of the decolorizing agent composition in Example 1 to 200Kg of water, and under the condition of pH 5, put 10Kg of purple sheepskin / mink skin into the bath, stir, heat up, and soak. The process conditions and fading effects are shown in Table 1.

Embodiment 3

[0021] In 200Kg of water, add 3Kg of the decolorizing agent composition in Example 1, and under the condition that the pH value is 7, 15Kg of chemical fiber cloth (yellow bright velvet / dark camel twill) is put into the bath, stirred, heated, and soaked. The process conditions and fading effects are shown in Table 1.

Abstract

The invention provides a depigment agent combination, comprising: sodium dichloro iso cyanurate 20wt%-95wt% and anhydrous sodium metasilicate 5wt%-80wt%. and it has low soaking damage to fabrics, able to effectively reduce environmental pollution and able to be widely applied to spinning and weaving, and printing and dyeing fields and coat and leather dyeing fields, having better depigment effect, not influencing redyeing and beneficial to resources recycling.

Description

technical field [0001] The present invention relates to a kind of auxiliary agent before printing and dyeing, in particular to an application method of a discoloration agent composition. Background technique [0002] Finished fabrics, fibers may form a backlog due to undesired color, or become defective due to uneven dyeing, affecting sales. In this case, if the existing colors on the fabrics and fibers can be removed, dyed (color-changed) again, and then resold, it can not only realize the reuse of resources, but also increase the profits of enterprises. [0003] The fading of fabrics and fibers is to fade the color on the colored fabrics and fibers to make it fade to its original white, bleached color, or reduce the color depth for re-dyeing. At present, the commonly used fading method is mainly bleaching method, that is to use bleaching agents such as sodium hypochlorite, hydrogen peroxide or sodium chlorite to bleach colored fabrics and fibers. When using sodium hypoch...
