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.
