Abstract
A new series of anthraquinoid red dyes were synthesized with 1amino2bromo4hydroxyanthraquinone and nalkylphenols 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 buildup 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 45 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
