摘　　要：In order to improve the antibacterial property of cellulose,a new N-halamine antibacterial material precursor was synthesized.1,2,3,4-Butanetetracarboxylic acid( BTCA) was used to attach the N-halamine precursor onto cotton fabric as the cross-linking agent. The synthesized compound was characterized by1 H nuclear magnetic resonance(1H NMR). The cotton fabric treated with Nhalamine precursor was characterized by Fourier transform infrared spectroscopy( FT-IR) and scanning electron microscopy( SEM).The antimicrobial efficacy, washing durability and UVA light stability were investigated. The cotton fabric treated with the Nhalamine precursor could be rendered biocidal after exposure to dilute household bleach. The chlorinated cotton fabric shows great antimicrobial efficacy,100% of Staphylococcus aureus( S. aureus)with 1.00 ×10~7 CFU and 99. 998% of Escherichia coli (E. coli)O157∶H7 with 2. 20 × 10~7 CFU can be inactivated with 30 min of contact. Washing durability tests indicate that over 55% of the chlorine can be regained upon rechlorination after 50 washing cycles,and UVA light stability tests show that over 62% of the chlorine can be regenerated after irradiation of 12 h.In order to improve the antibacterial property of cellulose,a new N-halamine antibacterial material precursor was synthesized.1,2,3,4-Butanetetracarboxylic acid（ BTCA） was used to attach the N-halamine precursor onto cotton fabric as the cross-linking agent.
