Disperse Dyes

Disperse Dyes

 

a group of poorly water-soluble dyes used for dyeing polyamide, polyester, polyacrylonitrile, and acetate fibers. Disperse dyes are characterized by the absence of the SO3H and COOH acid groups and a molecular weight of no more than 350. Disperse dyes are dispersed during their manufacture down to a particle size of 0.2-2.0 microns.

Synthetic dyes were perfected 150 years ago by a young chemist called William Henry Perkins, presumably the patron saint of all those cochineal beetles, and the disperse dyes for use on synthetic fabrics were invented in the early 1900s.
