UNION DYEING OF WOOL/POLYESTER BLEND FABRIC USING A SULPHATOETHYLSULPHONE DYE ANALOGUE OF C.I. DISPERSE YELLOW 16

Dyeing of wool, polyester and wool/polyester blend fabrics with a sulphatoethylsuphone dye analogue of the commercial C. I. Disperse Yellow 16were investigated. Maximum exhaustion values and colour yield were observed using the modified disperse dye at pH 7. The result showed that the modified disperse dye was more convenient for union dyeing of wool/polyester blend fabric compared with the commercial disperse dye. Excellent to very good wet fastness properties on all dyed fabrics were achieved using the modified disperse dye if compared with the commercial disperse dye.
