The principles of torsional and transverse vibrations have been utilized to measure the torsional and bending rigidities of fibers, respectively. A simple device, based on the principle of the torsional pendulum, has been designed to test regular and hollow staple fibers of fine denier. A vibroscope (interfaced with an oscilloscope) was used to measure the linear density of the fibers, and the results were used to calculate their torsional and bending rigidity properties. The effect of hollow core on the torsional and bending rigidities of the fibers is reported.
