摘要：

为解决涤/棉混纺或交织物靛蓝染料染色同色性较差的问题，探讨了保险粉、氢氧化钠和苯甲醇用量，染色温度和时间等工艺条件对模拟涤棉织物K/S值的影响，测试了染色织物的色牢度。结果显示：靛蓝上染涤纶和棉织物染色条件相差较大，一浴一步法很难使两种纤维染得同色；通过对涤/棉织物进行两浴法染色，第一次染色时靛蓝2%(omf)，在100℃加入苯甲醇20mL/L或120℃不加苯甲醇的条件下保温60min，第二次染色靛蓝6-8%(omf)，30℃保温60min，染色涤纶和棉织物有较好的同色性、满意的染色深度及一定的染色牢度。

Abstract:

For solving the problem that indigo dyeing polyester/cotton blended or mixed fabrics are difficult to reach good union dyeing effect. The effects such as dosage of sodium dithionite, sodium hydroxide and benzyl alcohol, dyeing temperature and time on K/S value of polyester/cotton fabrics were studied, and the color fastness of the dyed fabrics was also tested. The results showing that the polyester/cotton fabrics are hard to get union dyeing effect by one step and one bath method with indigo dyes as the dyeing process for single polyester and cotton fabrics are different; Polyester and cotton fabrics reached good union dyeing effect, satisfied dyeing depth and dyeing fastness when the fabrics first dyeing with indigo 2%(omf), at 100℃ with benzyl alcohol 20mL/L or 120℃ without benzyl alcohol for 60min, and then be dyed with indigo 6-8%(omf), at 30℃ for 60min.

Key words: polyester/cotton fabric, indigo dye, union dyeing, K/S value
