The Role of Glass-Transition Temperature of Polymeric Additives in Durable-Press Finishing of Knitted Cotton

Abstract

Polyacrylate and polyurethane additives to crosslinking treatments of circular knitted cotton fabrics are discussed. The effect on textile properties of varying glass-transition temperature in these polymers from -32 to +40°C is examined. Dimensional stability and strength of the finished fabrics are independent of polymer glass transitions. Fabric stiffness and resistance to flat abrasion increase and recovery from tensile strain decreases, with increasing glass-transition temper ature of the polymer additives.
