Modelling of the drying behaviour of regenerated cellulosic fabrics

Drying behaviour of garments during wear after any activity resulted in sweating is of great importance in terms of clothing comfort as well as heat and water vapour permeability for functional clothing design. the aim of this study is to analyze and model the drying kinetics of regenerated cellulosic fabrics which have increasingly use in casual clothing and sportswear. simulated drying experiments showed that modal and lyocell fabrics have similar drying behaviour although their supramolecular arrangement is quite different and drying rate is higher than viscose fabrics. moisture management tests proved that the drying behaviour is directly connected to the liquid moisture spreading capability of regenerated cellulosic fabrics. a two-stage modelling approach which is a combination of linear fit and thin-layer drying equations was tested for modelling of drying behaviour. logarithmic model was found to be the best fitted equation to represent the falling-rate drying period of regenerated cellulosic fabrics. moreover the sufficiency of the proposed model for the computation of drying rate was also proved.
