A polymeric dye was synthesised via the reaction of 2,4‐dinitrochlorobenzene and polyallylamine prepared from the homopolymerisation of monoallylammonium chloride. The polymeric dye was fixed to cotton and silk via a crosslinking agent [2‐chloro‐4,6‐di(aminobenzene‐4′‐β‐sulphatoethylsulphone)‐1,3,5‐ s ‐triazine]. The fixation of this polymeric dye reached 99% and the dyeing was fast to dimethylformamide at the boil, indicating that the dye fixation was through covalent bonding with the crosslinking agent, which acted as a bridge between the fibre polymer and the dye molecule. The dyed samples showed excellent fastness to washing and rubbing.
