초록
본 연구에서는 초임계이산화탄소 분위기 하에서 고분자섬유인 PTT (poly(trimethylene terephthalate))와 PET (poly(ethylene terephthalate))에의 분산염료 C. I. Disperse Yellow 54의 평형수착량을 온도와 압력, 그리고 시간에 따라 측정하였다. PTT와 PET 모두 온도와 압력이 증가함에 따라 염료의 수착량이 증가하였으나, 압력에 따른 수착량의 증가속도는 감소하였다. 또한 PTT가 PET보다 훨씬 더 큰 염료의 수착량을 나타냈으나, PTT와 PET 모두 같은 온도와 압력에서의 수착량의 증가속도는 시간이 지남에 따라 감소하였다.
In this study, the amount of equilibrium sorption of C. I. Disperse Yellow 54 dye in the polymeric textiles such as PTT (poly(trimethylene terephthalate)) and PET (poly(ethylene terephthalate)) textiles was measured in the presence of supercritical carbon dioxide at different temperatures, pressures, and time. The amount of dye sorption increased with temperature and pressure in both PTT and PET textiles, but the increasing rate decreased with pressure. The PTT textile has much larger dye sorption than PET textile. The increasing rate of dye sorption decreased with time at same temperature and pressure for both PTT and PET textiles.
