Study on Dyeing Equipment in Supercritical CO2

摘要：

This experiment studied supercritical CO2 dyeing by Disperse Red 167 on pure linen cloth. The solubility of dyes, the modifying of fabric and the dyeing process which primarily influenced dyeing results are analyzed. The optimum dyeing parameters are as follows: pressure=27MPa, temperature=120℃. After being dyed, the fabric was detected with infra-red spectrum and visual microscope; the dyed fabric was tested by the standard of GB251-1995 and GB250-1995. The result was that its fastness to crocking and washing could both reach grade 4.The rate of dyeuptake can be 82％. Because this water-free dyeing facility has the characteristic of dynamic dyeing, and the accumulation and remain of dye on fabric are reduced.
