Chelating dispersant is a kind of high-efficiency multifunctional organic chelate often used in the dyeing and finishing process. A substance that lowers the surface tension of water. It has the functions of wetting, penetrating, emulsifying, dispersing, solubilizing, etc. It can soften water quality, has strong complexation and scum dispersing power for calcium, magnesium, iron and other metal ions, and prevents sediments in the dyeing and finishing process. formation and scum produced by other dirt, and can slowly dissolve and remove silicon scale, calcium soap deposits and oligomers in the equipment, prevent metal salts from re-contaminating various fibers, and improve bleaching, dyeing, The whiteness, vividness and color fastness of printed products can also prevent the white background of printed products and yarn-dyed products from being stained again.
Chelating dispersant is a polymer surfactant with excellent dispersion and suspension functions, which can effectively prevent equipment and fabrics from being stained, and has a good effect on metal ions The complexation ability can effectively remove various metal ions; it can slowly dissolve and remove impurities such as calcium, magnesium, iron precipitates, and silicon scale on the equipment; it has good compatibility and has excellent resistance to acids, alkalis, oxidants, Reducing agent performance, can be used in the same bath with general pretreatment and dyeing auxiliaries. The foam is low, which can avoid the inaccurate feeding caused by the foam affecting the liquid level and affect the product quality, and will not cause firewood, deviation, wrinkling and other problems due to excessive foam.
Chelating dispersant Low foaming, good dispersibility, suspension, strong complexing force Chelating dispersant is suitable for fabric pretreatment, dyeing, soaping, etc. Various processes. When used in pretreatment, it can effectively complex various metal ions, and can effectively prevent the Fe3+ on the fabric from violently reacting with hydrogen peroxide to cause holes and other defects; when soaping after printing or dyeing, it can effectively remove reactive dyes And the floating color of other dyes, does not affect the dyeing, shade and whiteness of the fabric. Used in the dyeing process, it can soften the water quality, disperse the dye evenly in the solution, effectively prevent problems such as color spots, and help the fabric to obtain color.
