【摘要】 采用溶胶-凝胶技术,用0.37mol/LTiO2水溶胶处理后的纯棉织物的紫外线(297nm)透过率仅为0.8%,水洗牢度较好,具有一定的拒水作用,耐水压值达193.1Pa,淋水级数50分.与带有环氧基的硅氧烷水溶胶混合使用,能使直接染料皂洗的沾色牢度提高1~2级.更多还原

【Abstract】 The cotton fabrics treated with sol-gel technology using water-sol of TiO2 at 0.37 mol/L showed uv (297 nm) penetration as low as 0.8%, good wash-fastness and a certain degree of water-repellency (resistant to water pressure of 193.1 Pa, rinsing rate of 50 points). It could improve the direct dye fastness by 1 or 2 rates when used in soaping together with water-sol of siloxanes with epoxy groups.更多还原
