摘　　要：采用三聚氯氰和对位酯对β-环糊精进行改性,制得双活性反应型β-环糊精,然后与真丝反应制得β-环糊精接枝真丝织物,采用红外光谱、紫外可见光谱对接枝真丝及反应性环糊精进行表征,探讨环糊精接枝率的影响因素,并且优化了接枝工艺。结果表明,反应型β-环糊精可成功接枝真丝,而且保持了良好的包络性能。当反应型β-环糊精质量分数0.6%、NaHCO3质量浓度2 g/L、浴比1︰50、85℃处理45 min时,溶液中环糊精接枝真丝的接枝率为0.49%。A double reactive β-cyclodextrin was synthesized by the modification of β-cyclodextrin by cyanuric chloride and 4-aminophenyl-β-sulfatoethylsulfon, and then reacted with silk fabric to obtain β-cyclodextrin grafted silk fabric. The grafted silk fabric and reactive β-cyclodextrin were characterized by FTIR and UVVis spectroscopy. The factors affecting the grafting of β-cyclodextrin were studied and the optimum grafting process was determined. The results demonstrated that the reactive β-cyclodextrin could be successfully grafted onto silk fabric, and retained excellent inclusion property. When grafting condition was reactive β-cyclodextrin 0.6 % （owf）, sodium bicarbonate 2 g/L, liquid ratio 1 ： 50 and temperature 85 ℃ for 45 minutes, the grafting rate was up to 0.49 %.
