摘要
采用自制的水溶性聚氨酯(WPU)以提高活性染料染深色织物时的湿摩擦牢度。通过对其用量、焙烘温度、时间的探讨,确定了浸轧法处理染色织物的最佳工艺:WPU40g/L,120℃焙烘3min,可不加柔软剂处理。处理后织物干、湿摩擦牢度明显提高,且其它色牢度变化不大,耐氯牢度还有所提高。
In the paper, deep color fabrics were prepared with self-made waterborne polyurethane to improve the wet rubbing fastness of cotton fabric dyed with reactive dyes. Through discussion on the dosage, curing temperature and time, the optimal process of padding was settled, that is WPU 40 g/L,curing 3 min at 120℃ , and without softening. The results show that WPU can evidently enhance dry and wet rubbing fastnesses of fabrics with little affect on other color fastnesses, while the color fastness to chlorinated water is improved.
