摘　　要：合成了一种二酰亚胺化合物(N,N-二乙基间甲基苯甲酰胺),用于制备芳香族聚酰胺织物的抗紫外老化整理剂。通过改变操作条件(浓度、温度、时间),优化整理工艺,并对处理后芳纶织物的性能进行了表征。结果表明:经该整理剂处理过的芳纶织物在320～330 nm有较强的吸收峰;该织物经30 W紫外老化100 h后,强度保持率高达87%,比未经抗老化整理的对照织物样品的抗老化效能提高了一倍,表现出优异的抗紫外老化性能。In this paper,one kind of diimide compound（N,N-diethyl-m-toluamide） was synthesized,and it was used as protection against UV aging finishing agent for aramid fabrics.The finishing process was optimized and the properties of treated aramid fabrics were characterized.The results showed that the treated aramid fabrics had a strong absorption between 320～330 nm.The tensile strength retention of the treated aramid fabrics after UV-aging 100 h was 87 %,which was doubled compared to untreated blank fabrics.It is found that aramid fabrics after anti-ultraviolet treatment showed excellent ultraviolet resistant properties.
