高温型活性染料染粘胶织物应用探讨

Study on Dyeing Rayon with High Temperature Reactive Dyes

探讨了雅格素黄4RN、雅格素红6BN、雅格素藏青GN三支高温型活性染料在不同染色温度条件下染粘胶织物时染料的固色率、表面深度K/S值、染后织物的色光以及色牢度的变化。结果表明,当染色温度变化时,织物大部分色牢度没有明显的变化,但色光和固色率略有变化,其中织物表面深度K/S值在染色温度80℃至90℃时达到最大。

Three high-temperature reactive dyes Argazol Yellow 4RN,Argazol Red 6BN,and Argazol Navy GN were used to dye rayon at different temperature. The properties of dyed fabrics such as the dye fixation rate,color-depth K / S,shade and fastness were studied.The results showed that fastnesses of the dyed fabrics had no obvious change when the dyeing temperature changed,but the shade and the dye fixation rate declined or rose; and the color-depth K / S reached maximum between 80-90 ℃.
