摘　　要：制备了含Ag/TiO2的复合溶胶,并将其用于纺织品的抗菌整理;探讨了表面活性剂浓度、电解质浓度、pH值和温度对溶胶粒径的影响,并用透射电子显微镜(TEM)观察胶粒的形态;测定了水洗10次后整理织物上的Ag和TiO2的含量、织物抗菌效率的变化及其它性能,并采用X射线衍射(XRD)观察TiO2的晶型及Ag的价态。结果表明,采用含Ag和TiO2的纳米溶胶对织物进行抗菌整理后,抗菌效率可达99.9%,织物的抗紫外性能也有所提高,耐洗性较好,且对白度、断裂强力等性能影响不大。Composite sol with silver and titanium dioxide is prepared and applied to cotton fabric for antibacterial finish, effects of concentrations of surfactants and electrolyte, pH value and temperature on particle size are discussed, the morphology of sol particle is observed by transmission electron microscopy （TEM）, changes of silver and titanium dioxide contents, bacterial resistance and other properties after 10 cycles washing are measured, valence of silver and crystalline form of titanium are observed by X-ray diffraction （XRD）. Results show that nano-sized sol with silver and titanium dioxide can impart cotton fabric 99. 9% bacterial resistance, enhanced UV protection and durability to washing. The process exerts little influence on the whiteness and breaking strength.
