Synthesis and Characterization of Reactive Dyes based on 4, 4'-Diamino Diphenylsulphone and their Dying Application on Silk, Wool and Cotton fibres

Abstract

A series of hot brand bisazo reactive dyes have been derived by tetrazotised 4, 4’ diaminodiphenylsulphone with various cyanurated coupling components and their dying performance on silk, wool and cotton has been studied. The purity of all the dyes was checked by thin layer chromatography. The IR spectra showed all characteristic band and H1 NMR spectra of representative dye showed all the signals. The percentage dye bath exhaustion on silk, wool and cotton fibers was reasonably good and acceptable. The dyed fibers showed moderate to very good fastness to light, washing and rubbing.
