Hitherto it has been impossible to study the bending properties of fibers, yarns or fabrics, in the absence of bending testers for these materials. The author has devised a trial apparatus which measures the bending moment acting at one end of a sample which is bent in the shape of a partial cylinder of any radius. From the measurement is obtainable a diagram showing the relation between the bending moment and the curvature of the sample.
The practical capability of this tester is shown in a few examples in this article.
