A sustainable process for cotton and polyester/cotton blend dyeing with nucleophilic disperse dyes through chemical modification

In this study, the dyeing of cellulose fibre with disperse dyes is attempted by chemically modifying the cellulose fibre with a previously reported bifunctional cross-linker AXL-2 at a neutral pH. The modified cellulose was then dyed with nucleophilic disperse dyes containing amino and/or hydroxyl groups. One end of the cross-linker binds with the hydroxyl groups of cellulose, while the second one binds with the disperse dye molecule containing free NH2 or OH groups.
