Study of Energy-Saving Dyeing Process for Poly(lactic acid) Fabric

Abstract:

. This research studied to develop an energy-saving dyeing process for PLA. The disperse dye used was C.I. Disperse Red 167.1. The effect of dispersing agents viz. SLS and the commercial dispersing agent, on the dyeing ability of the dye on PLA was determined. An energy-saving dyeing process was developed as a 2-stage dyeing process. The dyebath was first preheated at 60°C for 10 minutes followed by dyeing at 110°C for shorter times of 10 and 20 minutes when the conventional process was carried out at 110°C for 30 minutes. The results show that the 2-stage dyeing process provides a satisfactory dyeing with less energy consumption as compared with the conventional PLA dyeing process.
