Tensile Properties and Fracture of Viscose Yarn under High Speed Impact

Abstract

In order to ensure an acceptable quality even at the highest spinning or weaving speeds, tensile instruments and testing conditions have to be improved. Therefore, a new high-speed dynamometer and a new method to subject yarns at strain rates similar to those found in current textile operations have been developed. This high-speed dynamometer has then been used to investigate the influence of high strain rates on tensile properties and fracture morphology of a technical viscose multifilament yarn.
