Abstract
This chapter highlights that the experimental methods for accessing the different properties of Shape Memory Polymers (SMPs) has provided a measure of the unique intrinsic properties this special class of functional polymer possesses. When these polymers are used together with fabrics or when fabrics are finished with these polymers, they require special characterization methods to access the effective transfer of the properties to the treated fabrics. The chapter reviews the evaluation instruments developed for cotton fabrics having unique thermo-responsive properties. It explores the use of SMPs with different formulations to finish woven cotton fabrics and to evaluate such thermo-sensitivity of shape memory fabrics, measurement of shape memory angle after immersing the fabrics in hot water. It also analyzes the difference between wrinkle recovery angle and shape memory angle. The chapter presents a definition of a shape memory coefficient to indicate the shape memory effects in fabrics. It discusses the efficacy of the evaluation methods and concludes that a new evaluation method has been developed for characterizing the shape memory fabrics.
