后铬媒介染料替代品的最新进展

New Developments in the Substitution of Afterchrome Dyes

这篇文章阐述了反应性染料作为后铬媒染料替代物的应用技术要点 ,对加工过程中染色各要素如温度、染浴pH值、匀染剂以及后处理条件对化学固色和羊毛质量的影响进行了讨论 ,这种讨论有助于更深入了解染色过程。

This article describes the technical know how require for the application of reactive dyes as a substitute for afterchrome dyes. A discussion of the effect of dyeing parameters such as temperature, dyebath pH, levelling agents and aftertreatment conditions on chemical fixation and wool quality provide deeper insight into the dyeing process. Details are given of experience gained in the wool industry, including further processing such as spinning.
