Disperse
Dye:
Disperse dyes are the only water insoluble dyes that dye polyester and acetate fibers. Disperse dye molecules are the smallest dye molecules among all dyes. A disperse dye molecule is based on an azobenzene or anthraquinone molecule with nitro, amine, hydroxyl, etc. groups attached to it.
