초록
초임계이산화탄소 분위기 하에서 C. I. Disperse Yellow 54 분산염료의 수착량을 압력, 온도 및 시간에 따라 측정하여 고분자 섬유인 PTT (poly(trimethylene terephthalate))와 PET (poly(ethylene terephthalate)) 내에서의 염료의 확산속도를 계산하였다. 고분자 섬유 내에서의 염료의 확산계수(diffusivity)는
Sorption of C. I. Disperse Yellow 54 dye in poly(trimethylene terephthalate) (PTT) and poly (ethylene terephthalate) (PET) textile fibers were measured at various pressures, temperatures, and times in the presence of supercritical carbon dioxide and thereby the diffusivities of the dye in the fibers were calculated. The diffusivity of dye in the polymeric fibers was very low, only in the order of
