초록
In this study, dyeability of PET fabric was investigated depending on dyeing temperature, pressure, and leveling time using laboratory scale supercritical CO2(scCO2) dyeing machine. Dyeing temperature, pressure, leveling time were varied from 100, 120, 130℃, 150, 200, 250bar, 40, 60, 80, 100min, respectively. It is proved that the higher temperature of scCO2 dyeing process, the higher K/S value and the lower L* value, which in turn means the lower amount of dyeing molecules remained after process done. Compared 200bar with 250bar of dyeing pressure, scCO2 dyeing fabrics under 250bar appeared to have a lower L* value, a higher K/S value than those from 200bar, meaning that dyeing color turns to darker with higher dyeing pressure. The experiments showed that the most ideal condition for scCO2 dyeing process is 120℃, 250bar for 60 - 100min of leveling time.
