摘　　要：以环氧氯丙烷、丝胶蛋白为原料,利用丝胶蛋白上的氨基对环氧氯丙烷进行取代反应,制成了一种新型的改性剂,通过乳化剂Le-001 15%(o.w.m)和Tween 80 10%(o.w.m)配制了该改性剂的复合乳化剂并应用于棉织物的整理,对整理后棉织物的红外光谱(FT-IR)、表面形貌、白度等进行测试。实验结果表明:含改性剂的复合乳化剂应用于棉织物的整理,改性剂能与棉织物上的羟基发生反应并固着于棉织物上,整理剂质量分数低时,改性前后棉织物的白度和毛细管效应没有明显变化;3次水洗后,棉织物的增重率处于恒定,进一步证明含丝胶的环氧化物改性剂与棉纤维上的羟基发生了化学反应,并固着在棉织物上;用于棉织物整理的改性剂的质量分数在5%～10%为宜,否则会影响棉织物的手感和强力。A new modifying agent was synthesized using epichlorohydrin and sericin protein by totally substituting reaction,and its composite emulsion,prepared by incorporating emulsifier Le-001 15%（o.w.m） and Tween 80 10%（o.w.m） into it,was applied to the treatment of cotton fabrics.FT-IR and SEM were used to examine the treated fabrics,and the whiteness was tested.The results showed that the modifying agent could react with hydroxyl groups of the cotton and fixed on the fabrics after the treatment.If the mass fraction of the finishing agent is low,the whiteness and capillary effect of the cotton fabric after treatment showed little change.The weighting percentage of the treated fabrics remained constant after 3 washing cycles,which further confirmed that the chemical reaction between the modifying agent and hydroxyl groups of the cotton had taken place and the agent had fixed on the cotton fabrics.The preferable mass fraction of the modifying agent was 5%-10% for cotton fabrics,otherwise the handle and strength of the fabric would be affected.
