Supercritical carbon dioxide fluid dyeing process of recycled polyester cheese
Supercritical carbon dioxide dyeing technology is used to dye recycled polyester cheese.The dyeing process is optimized,and the dyeing stability is explored.The results show that at a temperature of 120℃ and a pressure of 24 MPa,the maximum K/Svalue can be achieved with Disperse Blue 79 and Disperse Orange 30 for 60 min,and Disperse Red 60 for 90 min.The color fastness of the three dyes reaches Grade 4-5,which meets the requirements of national standards.The reflection rate curve indicates good dyeing stability without obvious intersection.
