Four crosslinkers were synthesised by the reaction of 1,3,5‐trichloro‐2,4,6‐triazine and polyethylene glycol. Their structures were confirmed by Fourier transform infrared spectra and mass spectra. A tetraethylene pentamine dye was crosslinked to cotton and silk via covalent bonds by the crosslinking dyeing process. The effects of pH, temperature, concentration and the chain length of the crosslinkers on the dye fixation were investigated in detail. The fixation of the dye using the crosslinkers on cotton and silk was >97%, and the infrared spectra of cotton, the dyed cotton and the crosslinked dyed one were compared with each other, which indicated that a covalent bond had been formed between the crosslinking dyes and fibres through the crosslinkers.
