Synthesis, Characterization and Dyeing Properties of an Alkali-Clearable Monoazo Disperse Dye on Polyester Fibres

Abstract:
characterized by analytical instruments such as DSC، FTIR، Mass spectra، 1HNMR، 13CNMR and UV-Visibletechniques. The synthesized dye was applied on polyester fabric according to HT method. Dyeing and fastnesses properties of synthesized dye on polyester fibres were investigated. The results showed that the synthesized dye had good build-up، excellent wash fastness and good light fastness on polyester fibres. Also، the elimination of the reduction clearing and its replacement with alkali clearing process of dyed fabrics was evaluated. The results represented that the synthesized dye is hydrolysable and removable from the surface of dyed polyester fabrics under alkaline condition. To this reason the reduction clearing process and consuming of sodium hydrosulfite were eliminated in the dyeing of polyester using the synthesized dye. J. Color Sci.
