摘要
在低温条件下制备掺银纳米二氧化钛溶胶，并将其应用于棉织物整理；通过X射线衍射、透射电镜和扫描电镜等对该溶胶结构和在织物上的状态进行表征；探讨不同掺银量对棉织物抗菌效果和白度的影响，以及整理棉织物的抗紫外线和降解亚甲基蓝等性能。结果表明，当钛酸四丁酯和硝酸银的摩尔分数比为70：1时，采用水蒸法整理，掺银纳米TiO2为锐钛矿相，粒径30～40nm，织物抑菌率可达93.5％，耐洗性较好，抗紫外线、降解亚甲基蓝等性能有所提高，对织物的服用性能则无明显影响。
Ag-doped nano-TiO2 sol is prepared at low temperature and is used to cotton finishing. The crystal structure and the distribution of nano-TiO2 on the fabric surface are observed by X-ray diffraction （XRD）, transmission electron microscopy （TEM）and scanning electron microscope （SEM）. The influence of amount of silver on antibacterial property and whiteness is discussed. The UV resistance performance and the degradation of Methylene Blue of cotton fabric after finishing are also investigated. Results show that Ag-doped nano-TiO2 with anatase phase and particle size of 30 -40 nm is formed on the fabric surface by steaming method with the molar ratio of tetrabutyl titanate to silver nitrate 70 ： 1, and the finished fabric features rate of bacterial inhibition of 93.5%, good fastness to washing, improved UV resistance and degradation of Methylene Blue, and no obvious influence on the wearability.
