Problems solved by technology

The enzyme-containing color bleaching powder is suitable for stain removal, bleaching and sterilization of colored fabrics and shirts, but the color bleaching powder absorbs a large amount of water vapor during the production process, which causes the problem of decomposition of oxidative bleaching agents, which is difficult to solve
[0005] CN105505621A discloses a neutral color bleaching powder, the components of which include enzymes, color-protecting agents, anti-redeposition agents, bactericides and solid fillers, and at least cellulase. strong, and can smooth the surface of the clothes and brighten the clothes. However, the neutral color bleaching powder needs to add a color protector to ensure that the washed fabric is more beautiful, and there is also the problem of the color bleaching powder absorbing water and causing the decomposition of the oxidative bleaching agent. question
[0006] Therefore, there is a need to develop a color bleaching powder, which not only has a good decontamination effect, but also can well solve the problem that the oxidized bleach absorbs water and is easy to decompose.

Embodiment 1-6

[0060] The specific components of the color bleaching powder provided in Examples 1-6 and the addition amount of the components (expressed by mass percentage) are shown in Table 1:

[0061] Table 1

[0062]

[0063] The preparation method of the color bleaching powder includes the following steps: turn on the dust removal fan of the mixer, first mix and stir calcium bentonite, tetraacetyl ethylene diamine and trisodium methylglycine diacetate at a speed of 70r / min for 25 minutes, and then mix with Yuanming powder, protease, lipase, amylase, cellulase, mannanase, maleic acid-acrylic acid copolymer and flavor are mixed and stirred at a speed of 80r / min for 15min, and finally mixed with the coated sodium percarbonate Mix and stir for 12 minutes at a rotational speed of 85 r / min, and sieving the mixed materials with 50 meshes to obtain the color bleaching powder.

Embodiment 7

[0065] This example provides a color bleaching powder. The difference from Example 1 is that the added amount of calcium-based bentonite is reduced to 3.0%, the added amount of coated sodium percarbonate is increased to 52.0%, and the other components The content and preparation method are the same as in Example 1.

Embodiment 8

[0067] This example provides a color bleaching powder. The difference from Example 1 is that the added amount of the calcium-based bentonite is increased to 15.0%, the added amount of the coated sodium percarbonate is reduced to 40.0%, and the other components The content and preparation method are the same as in Example 1.

Abstract

The invention provides colored bleaching powder and a preparation method thereof. The colored bleaching powder is prepared from the following components in percentage by mass: 3.0-20.0% of bentonite,40.0-75.0% of an oxidation bleaching agent, 3.0-15.0% of a bleaching activating agent, 0.5-5.0% of a chelating agent and the balance of anhydrous sodium sulphate. According to the colored bleaching powder, the oxidation bleaching agent is more stable in the storage process, and in the fabric washing process, the decontamination and bleaching effects on fabric can be achieved, and the softness andrewetting performance of the washed fabric can be improved.

Description

Technical field [0001] The invention belongs to the field of fabric washing products, and specifically relates to a color bleaching powder and a preparation method thereof. Background technique [0002] Color bleaching powder is the most commonly used powdery bleaching agent in the laundry industry and has been widely used. Color bleaching powder is an oxygen-releasing bleaching agent, which destroys various pigments and bleaches fabric fibers through the released active oxygen during use, so as to achieve the purpose of removing stains and increasing fabric whiteness; at the same time, it bleachs fabrics more gently , Will not damage the fabric, so the colorful fabric will be more beautiful after washing with the color bleaching powder. [0003] Color bleaching powder will inevitably absorb water vapor during the actual production and mixing process and storage process and increase the risk of active oxygen loss. This is more obvious in an environment with very high humidity. Un...
