Abstract: | A new series of magenta dyes having different length of alkyl substituents was synthesized to dye unmodified polypropylene (PP) and ultra-high molecular weight polyethylene (UHMWPE) fiber. It could be concluded that the affinity of the dyes onto unmodified PP and UHMWPE fibers was increased with the increase of the length of alkyl substituents. The optimum length of alkyl group was determined as the longest dodecyl-substituted dye in this study. Their absorption spectra appeared almost the same at visible range, which meant that the length of alkyl substituents did not affect the color appearance of the dyes. The color fastness properties of the dyeings to washing, rubbing and light were good enough for commercialization. |
