摘　　要：丙烯酰胺(AM)较马来酸酐(MA)有更高的接枝率。利用傅里叶红外光谱对AM/MA体系接枝的织物进行结构分析发现,AM与MA都接枝到织物上;利用核磁共振测试分析AM接枝涤纶织物的接枝机理,是涤纶大分子链α-H所在碳原子及部分脂肪链中的CH2与AM发生接枝;抗熔滴测试发现接枝AM/MA后的织物抗熔滴性能得到提高;扫描电子显微镜显示主要是骨架炭层起到支撑作用。he grafting ratio of acrylamide （AM） of polyester fabric is higher than that of maleic anhydride （MA）. The structure of AM/MA grafted polyester was characterized by FT-IR. The results indicate that the monomers of AM and MA are both grafted onto the fabric. The grafting mechanism was analyzed by 1H-NMR. The result indicates that α-H carbon atoms of polyester macromolecular chain and aliphatic chain CH2 react with AM. The resistance of melt drip test is found that the drop resistance of fabric is improved after being grafted with AM/MA, and the carbon skeleton acts as a support role to prevent melt drip observed by SEM.
