Elastic properties are found to be critical parameters for polymers which improve the wrinkle resistance of cotton fabric. Those molecular factors which results in optimum recovery of a polymer film from distortion (i.e., stretching) are shown to be directly related to the ability to improve fabric wrinkle recovery. Further, those molecular factors which inhibit the tendency of a polymer to form ordered structures allow the inherent flexibility of the polymer to be utilized in storing energy of distortion. This energy is then available, if the polymer is properly distributed on the fabric, to help overcome the fabric's frictional resistance to recovery. The most advantageous distribution of polymer is one in which interfiber and interyarn elastic bridges are formed.
