Description

Disperse dyes:
Disperse dye were originally developed for the dyeing of cellulose acetate, and are water insoluble. The dyes are finely ground in the presence of a dispersing agent and sold as a paste, or spray-dried and sold as a powder. Their main use is to dye polyester but they can also be used to dye nylon, cellulose triacetate, and acrylic fibres. In some cases, a dyeing temperature of **0 ° C is required, and a pressurised dyebath is used. The very fine particle size gives a large surface area that aids dissolution to allow uptake by the fibre. The dyeing rate can be significantly influenced by the choice of dispersing agent used during the grinding.

Disperse dyes are the only water insoluble dyes that dye polyester[1] and acetate fibers. Disperse dye molecules are the smallest dye molecules among all dyes. A disperse dye molecule is based on an azobenzene (as Disperse Red 1 or Disperse Orange *7)[2] or anthraquinone [3] molecule with nitro, amine, hydroxyl, etc. Groups attached to it.
