Abstract

Azo disperse dyes Ia-f - Va-f were synthesized from corresponding amines, where IR and visible spectra were evaluated. The prepared dyes were used for dyeing polyester, polyester woolen type and wool fibres.A range of bright and leveled shade have been obtained on application of these disperse dyes. The K/S values for various dyed substrate are in the following order, Wool > polyester/wool > polyester.
