摘要

采用超临界CO2技术对再生聚酯筒纱进行染色,优化了染色工艺,并对染色稳定性进行了探究.结果表明,在温度120℃、压强24 MPa的条件下,分散蓝79、分散橙30染色60 min,分散红60染色90 min,均可达到最大K/S值,且三种染料染色的织物色牢度均达到4～5级,染色反射率曲线无明显交叉,说明具有良好的染色稳定性.

Abstract

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.
