摘　　要：通过对超声波预处理后的羊毛纤维进行染色,并对染色前后的羊毛纤维性能进行测试,分析超声波对羊毛纤维低温染色预处理的最佳时长。研究表明,羊毛纤维经过超声波处理后,纤维的力学性能与结晶度均有不同程度的下降,而纤维的上染率与K/S值却有不同程度的上升。综合染色后羊毛纤维的性能,认为超声波预处理3 h为最佳处理时间。Wool fiber was dyed after ultrasonic pretreatment. Properties of wool fiber before and after low temperature dyeing were measured to optimize the time of ultrasonic pretreatment. Results showed that the mechanical properties and crystallinity of wool fibers pretreated by ultrasonic were decreased while dyeing rate and K/S value were increased. The optimized time of ultrasonic pretreatment was 3 h with comprehensive analysis of the properties for the dyed wool fiber.
