Study on the Properties of Core Spun Yarn and Fabrics of Shape Memory Polyurethane

Core spun yarn with shape memory fibre and cotton were developed using a ring spinning frame and friction spinning machine. Shape memory fabrics were woven from two kinds of shape memory core spun yarns, and the mechanical and shape memory properties of the yarns and fabrics were examined. The yarns have a good weave ability, and the yarns and fabrics have a good shape memory fix and recovery properties. This paper also introduces the application of shape memory yarns and fabrics in protective textiles and compares the shape memory properties of two kinds of shape memory core yarn and woven fabrics weft wise and warp wise.
