粘胶原液着色纺丝用还原染料色光稳定性的研究

A Study on the Color Stability of Spun-dyed Viscose with Vat Dyes

本文研究了还原染料应用于粘胶原液着色纺丝时,高浓度碱剂、带碱氧化和皂洗等工艺条件对其色光稳定性的影响,并分析其中的原因,为筛选可用于粘胶原液着色纺丝的还原染料提供依据。

Factors which could affect the color shade were investigated from high concentration of alkali, oxidizing with alkali and soaping,when vat dyes were used in spun-dyeing of viscose. And the reasons were also studied. It could be a suggestion to decide if a vat dye is suitable for spun-dyeing of viscose.
