20데니어 세섬도 나일론(Polyamide 6)을 위한 Anthraquinone계 산성염료의 합성 및 염색성 연구 = Synthesis and Application of Anthraquinone-based acid dyes for 20denier fine nylon fiber(plyamide 6)

다국어 초록 (Multilingual Abstract)

In this study, we developed a new non - metallised acid dye and applied it to fine nylon fiber, so we could confirmed good dyeability. In the case of an anthraquinone structure in which an electron donating group such as an amine group is substituted, it has molecular structural stability due to intramolecular hydrogen bonding. so we can expect high fastness characteristic. Finally, Dye 1, 2 were synthesized and the structures were confirmed. According to the results of UV-spectroscopy, Dye 1 and 2 containing sulfone groups are more bathochromic shifted than yellow Intermediate 1 and 2. so they are colored orange and scarlet, respectively.
As a result of comparing the dyeing properties of Dye 1, 2 on fine nylon fibers and conventional nylon fibers, the exhaustion(%) was higher when applied to fine nylon fibers though, and K/S values on same dye concentration(% o.w.f.) was higher on conventional nylon fibers. The reason for this result is due to the wide yarn surface area of fine nylon fibers. In addition, we confirmed the uniformity of the surface of the fiber depending on the initial dyeing heating rate, and the excellent leveling property was confirmed at the condition of gentle dyeing heating rate of 1℃/min. It was not influenced by the pH condition, but it showed the most excellent dyeability when the bath was weakly acidic such as pH 5-6.
Finally, the dyed fabrics with optimal dyeing conditions were estimated for wash and light fastness levels.
