Summary: | The effect of heat-setting treatment on the performance of cotton/elastane fabric has been studied. Response surface
methodology has been used to design the experiments where temperature (°C), time (s) and fabric width extension (%) are taken as factor variables. Fabric dimension (lengthwise and widthwise), fabric areal density and fabric tension decay are taken as response variables. The findings establish that the optimum heat-setting parameters are 190℃ temperature,
75s process time and 13.5% width extension. It is necessary to optimise the heat-setting parameters to achieve better fabric
dimensional stability, as overheating damages and deteriorates some of the elastane filaments, resulting in reduced recovery properties after a certain temperature point.
