摘要

A new series of anthraquinoid red dyes were synthesized with l-amino-2-bromo-4-hydroxyanthraquinone and n-alkylphenols to dye UHMWPE fibers with high light fastness. Their dyeability was examined depending on the length of alkyl chains. As the length of alkyl substituents increases, the dyeability toward UHMWPE fibers improves rapidly from methyl to ethyl substituents and maintains almost same level of color strength, and then decreases from heptyl to octyl groups. The color strength of dyeings increased dramatically with the increase of dyeing temperature from 100 °C to 130 °C. The maximum build-up was shown at around 5 % owf dye amount. From the dyeing rate, equilibrium dyeing was achieved at around 5 h at 130 °C. All kinds of fastnesses were good enough showing higher than ratings 4-5 to washing and rubbing for the longer alkyl substituents. Especially, much improvement was achieved in light fastness showing ratings 4, which was higher than ratings 2 of the previous study.
