摘　　要：采用甘氨酸(Gly)和乙二醇二缩水甘油醚(EGDE)对碱脆弱的羊毛织物进行加固,通过正交实验得到较优的加固方案:Gly质量分数为2%,EGDE质量分数为1.5%。在此加固条件下织物断裂应力提高了2.07倍,断裂应变提高了1.58倍。采用热重(TG)、X-射线衍射(XRD)、红外光谱(ATR-FTIR)等对Gly、EGDE与脆弱羊毛织物的作用关系进行分析探讨。结果表明:加固后样品的热稳定性增加,结晶度有所降低。初步证实EGDE与羊毛纤维发生了交联,推测认为Gly作为中间连接体与EGDE反应后作为加固剂,使得相距较远的角蛋白分子之间发生交联的可能性增大,形成较大的三维网状结构。Glycine（Gly）and ethylene glycol diglycidyl ether（EGDE）were used to consolidate fragile wool fabrics.A favorable consolidation condition was determined by orthogonal tests：the Gly mass concentration 2% and EGDE mass concentration 1.5%.In this condition,the breaking stress and breaking strain of the fabrics improved 2.07 and 1.58times respectively.The interaction effects between Gly,EGDE and wool fabrics were investigated by TG,XRD and ATR-FTIR.The results indicate that：heat stability of the sample enhances after consolidation;the degree of crystallinity reduces.The tests preliminarily verify that crosslinking occurs between EGDE and wool fiber.It is believed that Gly as the intermediate serves as the consolidation agent after reaction with EGDE so that the possibility that keratin molecules far away from each other crosslink increases and large three-dimensional network structure forms.
