Synthesis and dyeing performance of some novel thiazole azo disperse dyes

Abstract EN

The synthesis of some novel monoazo disperse dyes derived from 5-acetyl-2-amino-4-methylthiazole using various N-alkyl derivatives of aniline and their dyeing performance as disperse dyes have been assessed on cellulose triacetate fabric.

The spectral properties of these dyes were also measured.

The dyed fabric show good light fastness, very good rubbing, perspiration, washing fastness and excellent sublimation fastness.

These dyes have been found to give bright yellow to maroon color shade with very good depth and levelness on fabric.

The dye bath exhaustion and fixation on fabric has been found to be very good.
