Synthesis and characterization of some bi-functional reactive dyes and their application on various fibers
Author(s): YS Patel and KC Patel
Abstract: Various bi-functional reactive dyes have been prepared by coupling diazotized 4,4’methylene-bis-ortho-bromo aniline with cyanurated coupling components and their dyeing performance as reactive dyes has been assessed on silk, wool and cotton fiber. All the dyes gave yellow to marron shades with good to very good light fastness on each fiber. The purity of dyes was checked by thin layer chromatography. The IR spectra showed all characteristic bands and a representative dye’s PMR spectra showed all the signals. The percentage dyebath exhaustion on different fibers was reasonably good and acceptable. The dyed fibers showed moderate to very good fastness to light, washing and rubbing.
