Characteristics of anti-staining agents

The characteristics of the anti-staining agent, excellent dispersibility, can effectively prevent the redeposition of indigo dye; good anti-backstaining effect, prevent the trousers pockets and labels from staining; strong decontamination and floating color ability, improve washing fastness and cloth Brightness of face; Enzymes are washed with water to prevent back-staining when denim is desizing; Can be bathed with enzymes without affecting the activity of enzymes; Stable in acidic, alkaline and hard water, and compatible with various additives; Green environmental protection additives, without APEO and NPEO, in line with GB, European and American ROHS environmental protection standards; acid and alkali resistance, can be used in a wide range of pH; used for denim desizing, fermentation washing, fermentation grinding, excellent anti-back dyeing effect ;The anti-dyeing effect of polyester/cotton is particularly good; it can be mixed with various surfactants such as anionic, cationic, non-ionic, etc.; it can significantly improve the anti-backstaining effect; good stability, resistance to electrolytes and strong acid and alkali; temperature adaptation range Wide, 25 ℃ -80 ℃ can play its effect significantly; it is an environmentally friendly product, the price of anti-staining agent, APEO-free, no phosphorus, low foam, easy to wash with water; long-lasting anti-staining, fermented washing can still maintain good for 60 minutes The anti-staining effect of this product is higher; the higher the dosage, the better the anti-staining effect;

What is the anti-backstaining agent?

Denim is seen as a major trendsetter by our youth. The spread of denim culture around the world has brought about rapidly changing fashion trends. Several types of washing, such as stone washing, acid washing, and monthly washing, have been introduced successively. During stonewashing or enzymatic washing, the cellulose is degraded and the indigo dye is released. For example, cellulases are temporarily bound to cellulose through anchors. This differs in 1,4-beta glycoside composition. After this process, it can be used for further hydrolysis reactions. In order to avoid this kind of backstaining, which would reduce the value of the garments in the world market, some anti-backstaining agents are used in the sink. These reagents are added to the bath along with other chemicals associated with the corresponding wash. These agents prevent the redeposition of removed dyes on clothing. Anti-backstaining agent is mainly composed of three substances: 1 dispersant, 2 chelating agent, 3 emulsifier.

Classification of anti-staining agents

Anti-staining agents are divided into two types: mechanical and chemical: the former includes wax, grease and some inorganic compounds; the latter includes acids, alkalis, salts, oxidants, reducing agents, etc. There are also special anti-staining agents, such as phenylhydrazine sulfonic acid.
Mechanical resists are substances that prevent dyes from contacting fibers and prevent dyes from fixing on fibers. They can form a film on the surface of the fabric (such as kraft glue, gum, protein, etc.), or can be deposited on the surface of the fabric to retard the dyeing rate of dyes on the fabric, or retard the fixing rate of dyes (such as zinc oxide powder, Insoluble substances such as white powder, calcium carbonate and magnesium oxide), in the subsequent washing process, the ground color dyes in the pattern are washed away together with the mechanical resist to achieve the purpose of resist. In order to make the anti-staining effect good, sometimes a printing paste formulation contains both chemical anti-staining agent and mechanical anti-staining agent.

The function of the chemical resist is to chemically react with the chemicals required for the fixation and color development of the ground dye or the medium necessary for the fixation, and destroy the optimal conditions for the dyeing effect of the ground dye and the fiber. For example, ground color dyes need to develop or fix color in an acidic medium, and alkali or alkaline substances can be used as chemical resists; ground color dyes need to develop or fix color in the presence of oxidizing agents. Can be used as a chemical resist.
Some of these resists are applied to the fiber fabric, so that the dye cannot contact the fiber, such as paraffin, turpentine, starch, clay and barium sulfate. Some of them interact with dyes to make dyes invalid or precipitate, such as lime, lead sulfate, aluminum sulfate, calcium phosphate, etc. There are also anti-staining salt S (the main component of sodium m-nitrobenzene sulfonate) and anti-staining salt H (the main component of ammonium phenylhydrazine sulfonate). It is formulated into a dye-proof paste, first printed on the fabric and then dyed, and the pattern can be obtained after processing.

What users say about KINGSTAR

Our family is a small apartment, the bathroom is only about 4 square meters, I wanted a bathtub at that time, but I didn't expect it could be installed. I chose the bubble sitting style, because the space is too small, so it's very satisfied! Sometimes, if you order aromatherapy and pour a glass of red wine, any unhappiness during the day will disappear at this moment!


The solution provided is very satisfactory and the problem has been solved perfectly.


The anti-back-staining effect is not bad, and the effect of a trial batch of goods is not bad.


The service is in place, and the communication process is also very pleasant.
