Disperse dye

Disperse dye is a category of synthetic dye intended for polyester and related hydrophobic fibers. Disperse dyes are polar molecules containing anthraquinone or azo groups. It is estimated that 85% of disperse dyes are azos or anthraquinone dyes.[1][2]


The history of disperse dye production is closely related to the synthesis of cellulose acetate fibres. Disperse dyes were invented in 1923-24.[3]

Fundamentals of dyeingEdit

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.[5]
