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

In addition to the correct selection of dyes, reasonable dyeing and finishing processes can also improve wet rubbing fastness. The smoother the fabric surface, the higher the wet rubbing fastness, so the singeing should be clean, and the colored fiber particles should be reduced. The hair effect of the dyed semi-finished products directly affects the dye penetration of the dye. The better the penetration, the better the diffusion of the dye into the fiber after dyeing, which is beneficial to reduce the accumulation of dye on the surface of the fabric. The addition of penetrant and mercerizing treatment are beneficial to improve the wet rubbing fastness. Read More
