16th World Textile Conference - AUTEX2016, Ljubljana, Slovenia, 8 - 10 June 2016
In this work, conventional (HT) and microwave (MW) heating in the exhaust dyeing of the trilobal and round shaped polyester (PES) yarns were studied with C.I. Disperse Yellow 184/1, a fluorescent dye. The colouristic and fastness properties of the dyed fabrics and the effects of fibre cross-sectional shape on dyeing were investigated and compared with each other. Microwave dielectric heating provides many advantages over the conventional heating. It provides uniform dyeing in a very short time, good colour fastnesses and the repeatability in dyeing.
