摘　　要：以正硅酸乙酯为前驱体,在酸性条件下制备硅溶胶,将秦皮天然染料浸提液与硅溶胶共混杂化,制备秦皮天然染料杂化硅溶胶。扫描电镜照片显示染色后纤维表面形成了连续均匀的薄膜。优化的杂化硅溶胶制备工艺和染色工艺为:酯与水物质的量之比1∶7,pH值4,陈化温度60℃,硅溶胶与秦皮浸提液体积比1∶1;80℃染色30 min。染色产品K/S值显著增加且有较强的抗紫外线性能,织物力学性能增强。Using tetraethyl orthosilicate as precursor,silica sol is prepared under acidic conditions.The natural dye cortex fraxini is mixed with silica sol to prepare hybrid composite.Scanning electron microscopy shows that a continuous and uniform film is formed on the surface of the dyed fiber.The optimized preparation and dyeing process of hybrid silica sol are the molar ratio of ester to water 1∶7,pH 4,aging temperature 60℃,the volume ratio of silica sol to cortex fraxini 1∶1,and dyeing at 80℃for 30 min.The dyed products have significantly increased K/S value,excellent ultraviolet resistance and me⁃chanical properties.
