Abstract
Abstract: As a subsequent research of the previously reported 9) , a series of diaminoanthraquinoid blue dyes having hexyl,heptyl and octyl substituents were newly synthesized in order to investigate dyeability toward polypropylene fibers. As thelength of alkyl groups introduced to the chromophore increased, the dyeability of the dyes toward polypropylene fibers alsoincreased and then gradually decreased. From the result of dyeing, the hexyl-substituted dye showed the highest color strengthand deep shade on pure polypropylene fibers. The good fastness rates to wash, rubbing and light were also obtained for all ofthe synthesized dyes. Keywords: polypropylene, disperse dyes, dyeing, hydrophobicity, fastness 헥실기이상의알킬치환기를가지는디아미노안트라퀴논계청색분산염료의합성과순수폴리프로필렌섬유에대한염색성 곽동섭 1 · 김태경 † 1 한국염색기술연구소경북대학교섬유시스템공학과, Synthesis of Diamino-anthraquinonoid Blue Disperse D yes having Alkyl SubstituentsLonger than Pentyl Group and their Dyeability toward Pure Polypropylene Fibers Dongsup Kwak 1 and Taekyeong Kim
