Dispersant used for dye industry
Dispersing agent is a kind of auxiliary agent which can improve and modify the dispersing performance of solid or liquid materials. Dispersant is the main auxiliary agent in the process of dye processing, which plays an important role.
When the solid dye is ground, the dispersing agent is added to help the granules crush and prevent the particles from coalescing and keep the dispersion stable.
Dispersants are also surfactants. There are anionic, cationic, nonionic, amphoteric and macromolecular type. Anion is the most common. In addition to dispersing, many dispersants also have the effect of wetting, dilution, homogenizing and adjusting dye strength.
