ABSTRACT

Following the reported study that showed the dyeability of diamino-anthraquinoid blue dyes substituted with relatively shorter alkyl groups, the longer aliphatic substituents than pentyl group were examined in terms of the color strength and fastness properties toward UHMWPE fibers. The color strength was increased up to pentyl group and then gradually decreased. However, the fastness properties were improved continuously to octyl group which was the longest alkyl substituent in this study. The most effective maximum color strength was obtained at 130℃ for 2 hours with 3% owf of dyes. The overall fastnesses to washing, rubbing, and light were good enough for practical uses.
