The purpose of this study is to investigate the change of handle when cotton fabric is treated with chitosan-polyurethane mixed solution and crosslinked with epichlorohydrin in order to form three-dimensional crosslinks in the molecules, which in turn would improve the wash-fastness of the chitosan-treated fabrics. The application of epichlorohydrin decreased the EM(Tensile extensibility) and WT(Tensile energy) values, indicating the stiffness increased in the treated fabrics due to the 3-dimensional crosslinking. The crosslinking of the cotton fabric samples resulted in the increase in T.H.V. effectively for the use of summer dress shirt fabric.
