中文摘要：

采用溶胶-凝胶法制备的稀土离子（Tm）掺杂TiO2溶胶整理棉织物，在波长400—780nm的光照条件下，研究了稀土离子掺杂量、溶胶用量、陈化时间和光照强度对负载溶胶织物自清洁功能的影响。结果表明，织物的自清洁功能与溶胶的制备工艺和光催化工艺有关。在21．0mW／cm^2的光强下照射180min，Tm掺杂量为2％，溶胶用量0．5g／L和陈化5d的条件下，负载溶胶织物对污物的降解率可达到94％左右。棉织物整理后水洗20次，对污物的降解率为80％。但用该方法处理的棉织物，经纬向断裂强力和断裂伸长率均有一定程度的下降。

英文摘要：

Cotton fabric was treated with Thulium（Tm）-doped TiO2 sol which was prepared by sol-gel technique. With the spectrum of 400 - 780 nm irradiation, effects of doping concentrations of rare earth ions, sol dosage, aging time and illumination intensity on the self-cleaning properties of loaded fabric were discussed. The results showed that the self-cleaning performance of fabric was relative to sol preparation and photo-catalytic conditions. At 21.0 mW/cm^2 illumination intensity for 180 min,with the Tm molar ratio of 2%, aging for 5 days and sol dosage of 0.5 g/L, the degradation of pollutants was around 94%. Furthermore, the degradation of pollutants reached 80% with the loaded fabric after washing 20 times. While the breaking strength and elongation at break on warp and weft direction decreased after the treatment.
