高耐光牢度红色活性染料的轧染应用

Pad dyeing with red reactive dyestuffs of high light fastness

活性染料耐光牢度问题常见于三原色中的红色组分,其相对较低的耐光牢度,导致三原色组合整体耐光牢度的下降。文章从筛选染料入手,阐述了当前高耐光牢度红色活性染料的发展与现状;结合生产实践,介绍高耐光牢度红色活性染料应用在轧染工艺中的实践情况。

The poor light fastness of red component in trichromatic dyestuff always leads to low light fastness of the reactive dyeings. The development and present status of red reactive dyes with high light fastness are introduced. Combined with practical applications, applicability of several red dyes are discussed in pad dyeing.
