Abstract


Cotton/elastane fabrics are popular for their excellent stretch and recovery properties. However, the optimization of dimensional stability of such fabrics is quite challenging for the textile manufacturer. Heat-setting is one of the most common methods used to improve the dimensional stability of cotton/elastane fabrics. The aim of this study was to model the heat-setting process of cotton/elastane knitted fabrics using response surface methodology. Heat-setting time, temperature, fabric width extension (%) and overfeed (%) were taken as predictor variables while length- and width-way fabric shrinkage, and fabric areal density were taken as response variables. The developed response surface regression models can be used for predicting and optimizing the dimensional stability properties of cotton/elastane fabrics. It could be concluded by statistical analysis that all the predictor variables used in this study have significant effect of the dimensional stability of cotton/elastane knitted fabrics.
