利用溶胶-凝胶技术，以正硅酸四乙酯、3-叠氮丙基三乙氧基硅烷为前驱体，氨水为催化剂制备光固化二氧化硅溶胶，以十六烷基三甲氧基硅烷为拒水剂对棉织物进行拒水整理。先浸轧光固化二氧化硅溶胶，再浸渍烷烃硅氧烷，无需焙烘，通过紫外光照直接赋予织物拒水性能。采用扫描电镜、X射线光电子能谱仪对整理后的棉织物进行测试。结果表明，光固化二氧化硅溶胶沉积在织物表面，提高了棉织物的粗糙度。接触角测试表明，棉织物对水接触角(5μL)达到155°；整理后的棉织物经30次皂洗后，与水的接触角仍大于135°。

The light curing silica sol was prepared by sol- gel technology using tetraethylorthosilicate (TEOS) and 3- azidopropyltriethoxysilane as precursor, ammonia as catalyst, which was applied in water repel?lence on cotton fabrics with hydrophobic additives hexadecyltrimethoxysilane (HDTMS) as additive. The water repel ence property of fabric was endowed by dip- padding the light curing silica sol, then dipping into alkane siloxane, and then was exposed to UV light without curing. The treated cotton fabrics were characterized by scanning electron microscopy (SEM) and X- ray photoelectron spectroscopy (XPS). The results showed that the light curing silica sol nanoparticles were coated on the cotton fiber surface and increased the surface roughness. Contact angle results demonstrated that the water contact angle of the treated cotton fabric was 155° for 5μL and was stil greater than 135° after 30 times soaping.
