摘要
探讨了超声波提取茶叶色素的工艺,通过与沸水提取工艺比较,研究了超声波提取功率、超声处理时间对提取效果的影响,确定了最佳超声波提取工艺为超声波功率960 W,超声处理时间10min。并将提取的茶叶色素用于阳离子改性真丝染色,固色处理后真丝织物的摩擦牢度和耐皂洗牢度均有所提高。
The ultrasonic extraction process of black tea was studied. Compared with common extraction process, the influences of ultrasonic power and ultrasonic time on the extraction effects were discussed. The optimal extraction process was ultrasonic power of 960 W and ultrasonic time of 10 min. The extraction solution was used in silk dyeing which modified by cationic agent STC-6, and the fabric was dyeffixing treated with WQG-2. The color fastness of the treated fabric was improved.
