Abstract |
Abstract Supercritical fluid dyeing is a new alternative to the conventional aqueous
process because of its environmental benefits. In this study, dyeing properties of
Nylon 6 fabrics were investigated depending on dyeing temperature and pressure in
supercritical CO2 fluid dyeing system. In order to select the optimal condition for
supercritical fluid dyeing of Nylon 6 fabrics, dyeing temperature and pressure were
varied from 100, 110, 120¡É, 200, 230, 260bar, respectively. The results of K/S
values and levelling properties showed that the optimal dyeing condition for Nylon 6
fabrics was 110¡É and 230bar in the supercritical CO2 fluid dyeing system. The
washing fastness ratings of the dyed Nylon 6 fabrics under supercritical medium were
good for both fading and staining except for staining on nylon. |
