ABSTRACT

Novel super hydrophobic orange dyes having maximum absorption band at 450-500nm were synthesized todye polyolefin fibers such as polypropylene and ultra high molecular weight polyethylene fibers, using 4-alkylanilines andβ-naphthol. Their absorption spectra at visible range showed almost the same, which meant that the alkyl substituentsintroduced to chromophore did not affect on color appearance of the dyes. Considering both color strength and washfastness, the decyl-substituted dye was determined as the optimum one practically. From the dyeing results at variousconditions, the optimum dyeing was 130℃ for 1 hour with 5% owf of dyes. The good fastness ratings to washing,rubbing were obtained showing 4-5 for both fibers. Light fastness was also acceptable giving rating 3-4 for polypropylenefibers and rating 3 for ultra high molecular weight polyethylene fibers.
