This document discusses stiffness, drape, and methods for measuring these properties in fabrics. It defines key terms like handle, flexibility, rigidity, and drape. The Shirley stiffness tester and Cusick drape tester are described as methods that use cantilever bending principles and projected light areas to objectively measure a fabric's stiffness and draping ability. Factors that influence a fabric's stiffness and drape include yarn twist, fabric cover, thickness, weave, and chemical finishes. Higher twist, cover, and thickness increase stiffness while long floats and certain finishes improve flexibility and drape.
