摘　　要：由三乙胺和溴丙烯在丙酮溶剂中通过N-烷基化反应合成抗菌单体N,N,N,N-三乙基乙烯基溴化铵(TAAB),并通过雾聚合法制备抗菌棉织物。首先使用雾化硝酸铈铵水溶液处理棉织物表面,通过铈离子的氧化在纤维素分子链上生成自由基活性点,雾化抗菌单体(TAAB)溶液处理该活化棉织物表面,引发接枝聚合获得改性抗菌层。红外(FTIR-ATR)测试结果显示,抗菌单体已成功接枝聚合在棉纤维表面;抗菌测试结果表明,改性后的纤维织物对大肠杆菌等具有良好抗菌性,抗菌率可达90%以上。改性后的抗菌织物其透气、吸湿性能下降不多,拉伸性能有所提高。Antimicrobial monomer N, N, N, N-triethyl-vinyl ammonium bromide（TAAB）is synthesized by triethylamine and bromopropylene in acetone solvent through N-alkylation reaction and antimicrobial cotton fabrics are prepared with mist polymerization method.This study first uses atomizing ceric ammonium nitrate water solution to process the surface of cotton fabrics.Free radical active points are generated on cellulose molecular chain through the oxidization of cerium ion.The surface of this activated cotton fabric is processed with atomizing antimicrobial monomer（TAAB）.Graft polymerization is triggered and modified antimicrobial layer is obtained.Infrared（FTIR-ATR）test result shows that antimicrobial monomer has successfully grafted and aggregated on the surface of cotton fiber.Antimicrobial test result shows that modified fiber fabrics have good antibacterial property for escherichia coli and antibacterial rate can reach over 90%.Air permeability and hygroscopicity of modified antimicrobial fabrics do not reduce greatly and tensile property increases.
