Abstract
A series of ten fabrics, ranging from organdie through tracing cloth to a thick, stiff-finished cotton material, and varying in weight from approximately 5 milligrams per square centimeter (1.46 ounces per square yard) to approximately 45 milligrams per square centimeter (13.25 ounces per square yard), have been compared for bending length, rigidity, bending modulus, bending torque, chord length and radius of curvature by means of the drape tester, the hanging loop, Gurley stiffness tester and the Schiefer flexometer. The tests were all con ducted in an atmosphere closely approximating standard conditions after adequate conditioning of the samples in this same atmosphere.
