Domestic disperse dyes contain about 1/2 amount of anionic dispersants. The reason is: in the molecular structure of disperse dyes, there is no hydrophilic group (-SO3Na), so it has high hydrophobicity and low solubility. In water, due to the repulsion of water, the uncharged dye particles will natu Read More
