Morphology, wet, wrinkle resilience angle, UV protection and mechanics properties of viscose fabrics finished by nano silicon dioxide/silk distribution were observed and tested to study properties changes of viscose fabrics after nano silicon dioxide/silk treatment to search for the optimum content of the nano silicon dioxide/silk distribution finishing liquor. Research showed that when the nano silicon dioxide content was between 3.5% and 4.5% of the nano silicon dioxide/silk distribution finishing liquor, small reunions were appeared on the viscose fabrics. Meanwhile, properties of wet, UV protection and mechanics were all improved greatly except wrinkle resilience angle. On the whole, it was suggested that the nano silicon dioxide content of nano silicon dioxide/silk distribution should be controlled between 3.5% and 4.5% that functionalities of viscose fabrics can be improved greatly by this simple environmental protection technology.%研究了纳米二氧化硅在丝素与纳米二氧化硅复配整理液最佳含量.通过观察、测试自制丝素与纳米二氧化硅复配整理液对粘胶织物整理后的微观形貌、湿润、折皱回复性、紫外线防护与力学性能变化,说明复配液整理对粘胶织物的性能影响.结果表明,当纳米二氧化硅含量在3.5%～4.5%之间时粘胶织物表面的纳米二氧化硅出现少量团聚现象,且此时粘胶织物的疏水、紫外线防护与力学性能得到很大程度的改善,唯有粘胶织物的折皱回复性能略有降低.总体而言,通过此种简单环保工艺极大提高了粘胶织物的防护性能,因此建议复配整理液中纳米二氧化硅的含量应控制在3.5%～4.5%.
