Disperse dyes are substantially water-insoluble nonionic
dyes for application to synthetic hydrophobic fibers from aqueous dispersions.
Definition
Water-insoluble dyes,
which, when held in fine suspension, can
be applied to acetate rayon fabrics. The
dye, together with a dispersing agent, is
warmed to a temperature of 45–50°C and
the fabric added. By modifying the method
of application it is possible to dye polyacrylic
and polyester fibers. The yellow/orange
shades are nitroarylamine derivatives
and the green to bluish shades are derivatives
of 1-amino anthraquinone. Certain
azo compounds are disperse dyes and these
give a range of colors.
