Supercritical CO2 dyeing is a more environmentally friendly dyeing method. In this study, 5 different red disperse dyes were used for polyester in supercritical CO2 dyeing at different pressures, temperatures and time and then compare its levelness and color yield. From the results of that dyeing shows the dye Red 4 having a better relatively dye uptake than the other 4 dyes in supercritical CO2 dyeing. Under the dyeing conditions at a fixed temperature of 120℃ and time 3600 seconds of dye Red 4, the pressure to be more than 3000psi in order to obtain the leveling effect. Under the dyeing conditions at a fixed temperature of 120℃ and pressure 3625psi of dye Red 4, the time in 1200 seconds to obtain the leveling effect. Under the dyeing conditions at a fixed temperature of 3600 seconds and pressure 3625psi of dye Red 4, the temperature at 80℃ to obtain the leveling effect. From the results of dyeing fastness, in addition to dye Red 4 on nylon staining of the washing fastness is lower about 3-4 grade, the other of the dyeing fastness can reach more than 4 grades.
超臨界CO2染色屬於較環保的染色方式,此研究使用5支不同紅色分散性染料以以不同溫度、時間及壓力在超臨界CO2對聚酯進行染色布中,並比較其中的均染性與上色率。從其染色結果得知,染料Red 4較其他4支染料在超臨界染色中,具有較佳的相對上色率。染料Red 4在固定溫度120℃及時間3600秒條件下染色時,壓力需在3000psi以上才可獲得均染效果。在固定溫度120℃及壓力3625psi條件下染色時,時間在1200秒即可達到均染效果。在固定時間3600秒及壓力3625psi條件下染色時,溫度於80℃即可達到均染效果。從染色堅牢度的結果得知,除染料Red 4在耐水洗牢度對尼龍纖維染污3-4級偏低外,其餘各項染色堅牢度均可達到4級以上。
