Abstract
Wool was dyed with weak acid dyes and reactive dyes by ultrasonic wave.The optimum process was determined,the dyeing temperature was 60～70 ℃ at 60～90 min,and the ultrasonic frequency was 20～50 kHz.The washing fastness of dyed wool was improved with little rubbing fastness change.The soluble degree of dyes and the dyeing rate were increased without any damage for wool.
