Abstract: A polyamine crosslinking dye has been synthesized and applied to silk and cotton using crosslinking agents 2-chloro-4,6-di(amino-benzene-4'-beta-sulfatoethylsulfone)-1,3,5-s-triazine and 2,4-di-chloro-6-(aminobenzene-4'-beta-sulfatoethylsulone)-1,3,5-s-triazine, respectively. The effect of pH, temperature and concentration of crosslinker on fixation of the dye has been discussed in detail. The fixation of this polyamine dye reached near 100% and the dyeings were fast to dimethyformamide at the boils. This indicated that the dye fixation was achieved by covalent bonding with the crosslinking agent, which acted as a bridge between the fiber and the dye molecules. The dyed samples showed excellent fastness to washing and rubbing.
