The statistical investigation of the effect of hydrophilic polyurethane coating on various properties of denim fabric

Coating is a textile finishing process to add various properties onto fabric along with change at the appearance and it found commercial interest in denim market for the last decade. polyurethane (pu) polymer is one of the widely used coating materials for waterproofness and modified pu for breathable coatings have been developed but its effect on mechanical,performance and comfort properties has to be considered. this paper investigates the effect of pu coating on important mechanical,performance and comfort-related / breathability properties of denim fabric and evaluates the contribution of fabric and pu polymer weight at the final product.
