中文摘要：

以正硅酸乙酯、3-缩水甘油醚氧丙基三甲氧基硅烷（GPTMS）、乙醇、水和盐酸为原料制备硅溶胶,将直接大红4BS杂化其中,制备直接染料杂化硅溶胶。探讨该杂化硅溶胶的染色性能,并与直接大红4BS染色后固色剂固色工艺对比。结果表明,相对于染色后固色剂固色工艺,硅溶胶含量为40%,氯化钠质量浓度为10 g/L,焙烘温度为150℃,焙烘时间为5 min工艺下,染色K/S值提高了11.1%,干湿摩擦牢度各提高了1级,原样变色牢度和沾色牢度各提高了0.5级。杂化硅溶胶染色织物的拉伸断裂强力与未处理样相比略有增加,其中经向拉伸断裂伸长率增加11.6%。经杂化硅溶胶处理后织物弯曲刚度和弯曲滞后矩略增加,织物手感略减小。通过SEM照片可以看出杂化硅溶胶染色的纤维表面形成一层溶胶薄膜。

英文摘要：

A silica sol was prepared with TEOS,GPTMS,EtOH,H2O and HCl.The Direct Red 4BS was doped into this sol and formed a Direct Red 4BS contained hybrid silica sol.The dyeing proformance of Direct Red 4BS contained hybrid silica sol（Ⅰ） was investigated and compared with that of Direct Red 4BS alone but followed by a fixing process with fixing agent（process Ⅱ）.The results showed that when compared with（Ⅱ）,（Ⅰ） which used Direct Red 4BS contained hybrid silica sol containing silica sol 40%,NaCl 10 g /L and baking temperature 150 ℃ for 5 min exhibited enhancement in K /S value by 11.1%,raise in dry and wet rubbing fastnesses by one grade respectively,and improvement in color fastness（fading） and color fastness（staining） by half grade respectively.Compared with the untreated fabric,the fabric dyed with（Ⅰ） has better breaking strength（warp-wise increased by 11.6%）,better bending rigidity and bending hysteresis moment,but slightly lowered hand feeling.From SEM image,a silica film on the surface of the dyed fiber was clearly observed.
