Abstract |
Abstract The influence of the contact amount of carbon dioxide per unit mass of
dyestuff(¥á) on dyeing uniformity in supercritical fluid dyeing is analyzed in this study. The
experiments using a 5L class Pilot Scale dyeing machine is carried out for this study purpose.
For a fixed temperature and pressure, the amount of sample and the dyeing leveling
time were considered as process variables. The results show that the increase in the
amount of the sample causes a higher color difference than the reference sample, and it
also increases the amount of residual dye. On the other hand, the color difference tended
to decrease with the increase in dyeing time. Based on these results, the correlation between ¥á value and dyeing uniformity in supercritical fluid dyeing is obtained. |
