摘　　要：利用谷氨酸钠和苯丙氨酸钠作为阳离子改性剂对棉织物进行阳离子改性前处理,并对改性棉织物进行了染色研究。研究表明:采用谷氨酸钠和苯丙氨酸钠改性后的棉织物,分别采用不同染料进行染色,均可得到较高的K/S值,且各项色牢度指标都达到国家标准。相对于传统工艺,该染色工艺实现了降低盐碱用量的目的。The sodium glutamate and phenylalanine sodium are adopted as cationic agents in cationic modification of cotton fabric. The dyeing process of modified cotton fabric is studied. The result shows that the dyed cotton fabrics modified with sodium glutamate and phenylalanine sodium have good K/S value and color fastnesses. Compared to traditional dyeing process, the concentrations of inorganic salt and alkali of the new process are reduced.
