Abstract
The change in properties of cotton fabric produced by polymeric additives with varying degrees of stiffness or softness has been investigated by measuring these properties at different temperatures. It was concluded that changes in crease-recovery angle produced by these polymers were not due to lubrication but were related to the elastic-recovery properties of the added polymer. Changes in tear strength and abrasion resistance were shown to be a function of interyarn mobility by measuring yarn withdrawal forces of the fabrics. Radiation-induced deposition of polymers produced changes that were qualitatively similar to those made by conventional polymer applications, but the changes were not as pronounced. This was attributed to the lower degree of surface deposition and the lack of cross-linking of the radiation deposited polymers.
