超声波在酸性染料染丝绸中的应用

Application of Ultrasonic Wave to Dyeing Silk with Acid Dyes

以酸性大红G上染丝绸为例,对超声波在染色中的应用进行了研究。结果表明,与常规染色相比,采用超声波进行染色可以提高染料的上染百分率,降低染色温度,缩短染色时间,增加扩散系数,降低染料上染的活化能。

The application of ultrasonic wave to dyeing is studied with the example of bright red acid G dyeing silk. The resultshows that dyeing with ultrasonic wave can improve the dye uptake, low dyeing temperature, shorten dyeing time, increase diffu-sion coefficient and decrease the activation energy of dyes comparing with normal dyeing.
