Abstract

M. S. Patel, S.K. Patel and K.C. Patel*

Various hot brand reactive dyes have been prepared by coupling diazotised 4,4'-methylene-bis-ortho-chloroaniline with various anilino cyanurated coupling components and their dyeing performance as hot brand reactive dyes have been assessed on viscose rayon, wool and silk fibres. These dyes have been found to grve a wide range of violet to brown shades with very good depth and levelness on each fibre. The purity of all dyes have been checked by thin layer chromatography. The IR spectra of all these dyes showed all charactenstic band present in the dye molecules. The percentage dye-bath exhaustion on different fibre have seen found to be reasonably good and acceptable. The dyed fibres show fairtogood fastness to light, washing and rubbing.
