摘　　要：以γ-氨丙基三乙氧基硅烷(APTES)为偶联剂在棉织物表面连接氨基,然后利用氨基与银离子的络合作用在棉织物上负载银。探讨了偶联剂浓度、偶联温度、络合温度等因素对银负载量的影响,并测试了载银抗菌棉织物的抗菌性能。结果表明,偶联处理的优化工艺为:偶联温度50℃,偶联剂用量0.4%;络合反应的优化工艺为:络合温度35℃,反应时间100 min。经过处理得到的载银抗菌棉织物对大肠杆菌和白色葡萄球菌都具有良好的抗菌性,且经10次洗涤后,抗菌性能仍显著。Aminopropyltriethoxysilane （APTES） was used to anchor amino groups on the surface of cotton fabric, and Ag was loaded by the complexation of amino groups with Ag^＋. The effect of coupling agent concentration and coupling temperature on the loading capacity of silver on cotton fabric were studied, and antibacterial property of the cotton fabric was tested. The results show that the optimized conditions of coupling process are that coupling temperature is 50 ℃, and the concentration of coupling agent is 0.4%. The optimized condition of complexation reaction are as follows： the complexation temperature is 35 ℃ , reaction time is 100 min. The antibacterial property of the Ag-loaded cotton fabric to Escherichia coli and Staphylococcus albus is farely well even after 10 times washing.
