Description
A class of water-insoluble dyes that are usually applied as aqueous dispersions. First used in 1923 for dyeing acetates, disperse dyes are now also used for other types of synthetic fibers, such acrylic, nylon, and polyester. Disperse dyes contain amino groups in the following classes: nitroarylamine, azo, and anthraquinone. In addition to dyeing from an aqueous dispersion, high-temperature (100-130C) and/or pressure to incorporate the colorant into a synthetic fiber. After dyeing, the fibers may remain untreated or may be fixed with heat (thermosol) or diazotization treatments. They provide good lightfastness and washfastness. Also used for heat-transfer printing.
