  • A new series of anthraquinoid magenta dyes having alkylphenyl substituents was synthesized and applied toward pure polypropylene fibers. The affinity of the dyes toward polypropylene fibers was increased gradually with the increase of the length of alkyl substituents. The optimum length of alkyl group was determined as heptyl substituents from the practical point of view. The color values of the dyes on polypropylene fabrics displayed slight bluish red, namely magenta which is more practical than primary red in color matching. The good fastness ratings to washing, rubbing and light were obtained for the dyes having longer alkyl groups than hexyl substituents. Expecially they exhibited ratings 4 of light fastness, which is higher than primary red dyes previously reported.

  • 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 $130^{\circ}C$ for 2 hours with 3% owf of dyes. The overall fastnesses to washing, rubbing, and light were good enough for practical uses.

  • The optical and physical properties of alkyl-substituted anthraquinoid dyes were investigated in terms of dyeing of pure polypropylene fiber. The length of alkyl substituents of the dyes did not affect the molar extinction coefficient and maximum absorption wavelength of them. The use of a double-tailed cationic surfactant, didodecyldimethylammonium bromide(DDDMAB), could make the hydrophobic dyes dispersed in water effectively. As the amount of DDDMAB increased, the average particle size of dye dispersion decreased. Maximum color strength of the fabrics was shown in the case that 1.5 molar ratio of DDDMAB was used. As for the fastness properties, commercially acceptable result was obtained in general.

  • The dyeability and fastness properties of super-hydrophobic navy dyes having different length of alkyl groups were investigated on ultra high molecular weight polyethylene fabrics. Those dyes exhibited strong color strength in the wavelength of mainly 550~650nm, which meant that they were navy color. From the results accomplished under various dyeing conditions, it can be concluded that those dyes have higher affinity on the fibers at $130^{\circ}C$ than at the lower dyeing temperature. Considering processing time and thermal damage of the fibers, one hour is good enough to obtain full strength of color. Maximum color strength was obtained at 2~3%owf of pure dyes. Except for the rub fastness under dry condition, all fastness such as to washing and light showed as good as of 4~5 ratings.
