Abstract
Dyeing of PET yarn in supercritical carbon dioxide can reduce water usage, prevent pollution and save energy. Effects of supercritical conditions on the uniformity of PET package were investigated with a pilot plant. It was found that the uniformity of PET package is improved as the CO2 flow rate increasing. The dyeing process with optimum flow reversal yield more uniform samples than those without, the most optimized reversal interval is 15 min. Both the uniformity and the percent exhaustion of PET package dyed with this pilot plant were shown good reproducibility. The wash and rub fastness properties of PET yarn dyed in the plant were good to very good.
