摘　　要：以环氧氯丙烷、丝胶蛋白为原料,在碱性条件下制备新型丝胶改性剂.丝胶改性剂与涤纶织物上的羧基发生酯化反应并固着于涤纶织物上,改善涤纶织物的抗静电性、吸湿性等性能.对整理后涤纶织物的抗静电性、透气性、毛细效应、接触角、强力等进行测试.结果表明:改性涤纶织物的抗静电性得到改善,表面电荷由原来的0.036μC变为0.001μC;多次水洗后,涤纶织物表面电荷基本稳定,说明丝胶改性剂与涤纶织物上的羧基发生酯化反应,并固着在涤纶织物上;透气性由原来的19.43 mm/s变为46.29 mm/s.A novel sericin modifier was prepared using epichlorohydrin and sericin protein as raw materi-als under alkaline condition. The sericin modifier reacted with the carboxyl groups on polyester fabric through esterification reaction and fixed onto the fabrics, improving the antistatic and hygroscopic properties of polyes-ter fabrics. The antistatic, gas permeability, capil ary effect, contact angle and strength of finished polyester fab-ric were tested. The results showed that the antistatic property of modified polyester fabric was improved and the surface charge changed from 0.036 μC to 0.001 μC. After repeated launderings, the surface charge on the finished polyester remained steady showing the esterification reaction between the sericin modifier with the carboxyl groups on polyester fabrics. The gas permeability also increased from 19.43 mm/s to 46.29 mm/s.
