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]
History
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 dyeing
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]
Examples
- Disperse Orange 1 is an azo dye.
- Disperse Red 9 is a red dye derived from anthraquinone.
- Disperse Red 11, also called C.I. 62015 and 1,4-diamino-2-methoxy anthraquinone, is another anthraquinone dye.
- Disperse Red 60 is also an anthraquinone dye.
- Disperse Yellow 26 is a yellow disperse dye.
- Disperse Yellow 42 is prepared by the reaction of two equivalents of aniline with 4-chloro-3-nitrobenzenesulfonyl chloride.
