Application of chelating dispersants in dyeing and finishing

Chelating dispersant is a highly efficient and multi-functional organic chelate compound often used in dyeing and finishing processes. It is a surfactant and is a substance that can significantly reduce the surface tension of water. It has the functions of wetting, penetrating, emulsifying, dispersing, and solubilizing. It can soften water quality, has strong complexing effect on calcium, magnesium, iron and other metal ions and scum dispersing power, and prevents sedimentation during dyeing and finishing processes. and scum generated by other dirt, and can slowly dissolve and remove silicon scale, calcium soap precipitates and oligomers in the equipment, prevent metal salts from re-contaminating various fibers, and improve bleaching, dyeing, It can improve the whiteness, vividness and color fastness of printed products, and at the same time prevent the white background of printed products and yarn-dyed products from being stained again.

Chelated Synthetic dispersant is a polymer surfactant with excellent dispersing and suspending functions, which can effectively prevent equipment and fabrics from being stained. It has good complexing ability for metal ions and can effectively remove various metal ions; it can be slowly dissolved It also removes calcium, magnesium, iron precipitates, silicon scale and other impurities on the equipment; it has good compatibility and excellent acid, alkali, oxidant and reducing agent resistance and can be used in the same bath as general pre-treatment and dyeing auxiliaries. . The low foam can avoid inaccurate feeding caused by the foam affecting the liquid level and affecting the product quality, and it will not cause problems such as firewood, deviation, and wrinkles due to excessive foam.

Chelated dispersants have low foaming properties, good dispersion and suspension properties, and strong complexing force. They are suitable for fabric pre-treatment, dyeing, soaping and other processes. When used in pre-treatment, it can effectively complex various metal ions, which can effectively prevent Fe3+ on the fabric from reacting violently with hydrogen peroxide to cause defects such as holes; it can effectively remove reactive dyes when soaping after printing or dyeing. And the floating color of other dyes does not affect the dyeing, color light and whiteness of the fabric. Used during the dyeing process, it can soften the water quality and evenly disperse the dye in the solution, which can effectively prevent problems such as color spots and help the fabric obtain color.
