活性染料高温染色技术的研究进展(二)——活性染料高温染色的若干关键问题

Research developments of reactive dyes used in high-temperature dyeing(Ⅱ)

针对高温型活性染料在分散/活性一浴一步法染色工艺中存在的问题,分析了高温下染料的反应性和稳定性,研究高温对活性染料染色热力学和动力学的影响,以及高温染色中固色用碱剂的设计,以深入了解活性染料在高温下染色问题产生的原因。

Aiming at the problems in application of high-temperature reactive dyes to disperse/reactive one-bath one-step process, the reactivity and stability of reactive dyes under high temperature, the ef- fect of high temperature on dyeing thermodynamics and kinetics, and the design of alkali agent for color fixation in high-temperature dyeing are studied. The dyeing problems of reactive dyes under high tem- perature are further studied.
