Textile industry involves a crucial energy-intensive drying stage to remove the moisture left. Determining drying characteristics for fibers is vitally important so as to optimize the drying stage. This paper describes a way to determine the drying characteristics of fibers with analytical method developed for this purpose. The model presented, is based on fundamental heat and mass transfer equations. The results from the parametric study provide a better understanding of the drying mechanisms and may lead to a series of recommendations for drying optimization.
