Descrição

In order to ensure an acceptable quality even at the highest spinning or weavings 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 find in current textile operations have been developed. This high speed dynamometer has than be used to investigate the influence of high strain rates on tensile properties and fracture morphology of a technical viscose multifilament yarn.
