Disperse dyes are polar molecules containing anthraquinone or azo groups.[1][2] The history of disperse dye production is closely related to the synthesis of cellulose acetate fibres.[3] Disperse dyes are non-ionic in nature and partially soluble in water.The interaction of dye molecule and polymer takes place with Van der Waals and dipole forces.[4] Disperse dyes have better diffusion at boiling to a higher temperature.
