The Research of Cleaning Process for Supercritical Carbon Dioxide Dyeing Equipment

Abstract:

A cleaning process for dyeing apparatus was investigated by employed a self-developed supercritical equipment. The solubility of C.I. Disperse Red 167 was evaluated with acetone, ethanol and carbinol in supercritical carbon dioxide at temperatures of 60, 80,100 and 120 °C and pressures ranging from 12 to 28 MPa. As revealed from the experimental results, the optimal cleaning conditions were as follows: cleaning temperature 100 °C, cleaning pressure 18 MPa, and cleaning time 40 min. Acetone was the most suitable cosolvent and the best cleaning effect was obtained when its concentration was 1%.
