摘　　要：主要研究超声波在酸性染料染羊毛中的染色性能。选用常规染色和超声波染色对羊毛织物进行酸性染料染色,比较了2种染色方法的染色动力学。利用超声波酸性染料染色羊毛,与常规染色相比,超声波在染液中会产生强烈的空穴效应,染色速率常数较大,扩散活化能较高,染色温度较低,皂洗牢度有所提高,在低温条件下染色,对纤维损伤较小。超声波条件下,酸性染料对羊毛织物进行染色,可以在相对较低的染色温度(70℃)让酸性染料上染羊毛织物,并能获得较好的染色效果。This paper mainly researched the ultrasound dyeing method in acid dyes on wool. The dyeing dynamics of conventional and ultrasound dyeing method were compared. The ultrasound dyeing method will produce strong cavitation effect, had higher dyeing rate constant, higher diffusion activation energy, lower dyeing temperature, better washing fastness. Due to the low dyeing temperature, the wool fiber had lower damage. As a result, ultrasound dyeing method in acid dyes on wool can dye in relatively low temperature （70 ℃ ） , and can obtain good dyeing effects.
