摘　　要：利用环糊精水解物的还原性还原银氨络离子得到纳米银溶液,并通过动态光散射粒径分析、透射电子显微镜表征所得纳米银的粒径大小和分布。采用纳米银胶体溶液对纯棉织物进行抗菌整理,测试了整理后棉织物的抑菌性能。当银氨溶液的浓度为0.0005mol/L时,最终整理后的棉织物对大肠杆菌和金黄色葡萄球菌的抑菌率分别达到99.42%和99.57%,且洗涤50次后仍有92%以上的抑菌率,耐洗性能良好。Silver ammonia complexion was reduced by cyclodextrins hydrolysate to get nano-silver solution. The size and size distribution of nano-silver were measured by HPPS and TEM. Then the solution was used to treat cotton fabrics, and the antibacterial performance of treated fabrics was investigated. The results showed the finished cotton fabrics had excellent antibacterial performance against Escherichia coli （E.coli） and Staphylococcus aureus （S.aureus）, with bacteriostasis rate respectively up to 99.42% and 99.57%. And it remained more than 92% after washing 50 times.
