Resist Salt S is a common auxiliary agent widely used in the textile printing and dyeing industry, and it is a typical non - toxic and stable inorganic salt auxiliary. It is usually presented as white crystalline powder, which is easily soluble in water and has good chemical stability under normal printing and dyeing conditions. It does not react with most dyes, auxiliaries or textile fibers, and can maintain stable performance in a certain range of acid - base environments.

Main Application Scenarios

1. Textile Vat Dye Resist PrintingThis is the core application field of Resist Salt S. In the vat dye printing process, it is mainly used as a resist agent and reducing stabilizer. When printing patterns on fabrics, Resist Salt S can be added to the resist paste. It can inhibit the reduction reaction of vat dyes in the resist area, so that the dyes in this area cannot be reduced to leuco form and thus cannot combine with fibers. In this way, clear white patterns can be formed on the dyed fabric background, ensuring the sharpness and definition of the pattern edges. At the same time, it can stabilize the reducing system of the dye bath, prevent excessive reduction of dyes and avoid color fading or color change of dyed fabrics.
2. Textile Reactive Dye Printing AuxiliaryIn the reactive dye printing process, Resist Salt S can be used as an auxiliary to adjust the dyeing rate. It can slow down the reaction speed between reactive dyes and fibers in specific areas, assist in controlling the dye uptake of fibers, and avoid color stains or uneven dyeing caused by too fast reaction. It is especially suitable for printing products with multi - color overlapping or gradient color requirements.
3. Color Fixing Auxiliary for Blended FabricsFor blended fabrics containing cotton, linen and other cellulose fibers, Resist Salt S can be used as an auxiliary in the post - dyeing color fixing process. It can improve the binding fastness between dyes and fibers to a certain extent, reduce the color fading phenomenon of fabrics during washing or rubbing, and enhance the color fastness of printed and dyed products.
4. Other Auxiliary ApplicationsIn some industrial fields such as pigment printing, Resist Salt S can be used as a dispersing auxiliary to improve the dispersion stability of pigment pastes and prevent pigment particles from agglomerating, thus ensuring the uniformity of pigment printing. In addition, it can also be used as a buffer in some water - based coating systems to adjust the pH value of the system and maintain the stability of the coating formula.
