Four kinds of cationized cottons such as acrylamide-cotton(AAM-cotton), aminoethyl cotton(AME-cotton), N-methylolacrylamide-methylamine-cotton(NMA-MA-cotton) and poly-epichlorohydrin-ethanolamine -cotton(PECH-EA-cotton) were prepared and their dyeing properties with reactive dyes were examined. All four cationized cottons could be dyed with reactive dyes using a small amount of electrolyte and alkali, especially NMA-MA-cotton could be dyed without electrolyte and alkali. The dye fixation on AAM-cotton, AME-cotton and PECH-EA-cotton were increased with alkali concentration in dyebath but that of NMA-MA-cotton was decreased. The wash fastness of cationized cottons was generally good and light fastness of AME-cotton was grade 4~5.
