摘　　要：以干燥石榴皮作为原料,用水煮法提取天然石榴皮色素对羊毛纤维进行常规染色和超声波染色,研究染液浓度、染色时间、染浴pH值、染色温度对石榴皮染色羊毛的染色深度和颜色特征值的影响。实验结果表明:石榴皮色素适合于羊毛纤维的染色,超声波对石榴皮色素上染羊毛纤维具有明显的增深作用,随着染液浓度、染色时间和染色温度的增加,染色羊毛纤维的K/S值增加;超声波染色条件下的石榴皮染色羊毛纤维的耐皂洗牢度和摩擦牢度有一定的提高,均达到3级以上。Compared with the traditional dyeing method,ultrasound dyeing can improve the dyeing efficiency,reduce the sewage discharge,dye amount and dyeing auxiliary,and improve dyeing depth and color fastness.In this study,dried pomegranate peel was selected as dye material and was extracted using boiling method.Then wool fiber was dyed with pomegranate extraction.The effects of ultrasonic,pigment concentration,dyeing time,pH value of dyeing bath and dyeing temperature on K/S value were studied.The results showed that pomegranate pigment had good dyeability to wool fiber and the ultrasonic improved dyeing performance obviously.K/S value of the dyed wool fiber increased with the increase of dyeing time,concentration and temperature.When it dyed with the ultrasonic,both washing fastness and rubbing fastness were above grade 3.
