中文摘要：

选用环保载体，用阳离子染料对芳砜纶织物染色．对载体（Levegal C45）用量、无机盐种类及其用量、染色温度、染色保温时间等进行了优化，得到了优化工艺：Levegal C4540mL／L，NaCl 10g／L，130℃保温染色30min．用此工艺放样后测定织物的各项牢度均较好，说明工艺可行，适合于大生产．

英文摘要：

Polysulfone fabric was dyed with cationic dye using environmental friendly carrier. The dosage of carrier Levegal C45, kinds and dosages of inorganic salt, dyeing temperature, dyeing holding time were optimized. The optimal technique was obtained： Levegal C45 40 mUL, NaCl10 g/L, dyed at 130℃ for 30 rain. Under the optimal dyeing technique, the various color fastness of lofting dyed fabric were all good, which indicated the technique was feasible and fit for big production.
