Disperse Dyes - Classes, Properties, Process, Methods, applications

A disperse dye is a dye with extremely low solubility in water but in which it is in a finely dispersed state. The size of a disperse dye particle is in the region of approximately 0.5 - 1 mm. Disperse dyes are applied in the form of a fine aqueous dispersion. The fibres most readily coloured by disperse dyes are cellulose acetate, polyester, acrylic and nylon. Chemically, the disperse dyes belong to various classes such as azo, anthraquinone, methylene, and diphenylamine. They are non-ionic dyes and do not have any polar groups.
