Correlation Between The Initiated Tear Of A Fabric And Its Constituent Yarns

Abstract

This article represents the relationship between the initiated tearing of a fabric and the yarns’s characteristics with which the fabric is made. There are several characteristics that were considered: the tensile strength of the yarns, the real metric number of the yarn, the elongation of the yarn, the kilometric resistance of the yarns and the hairiness index of the yarns. To better understanding this correlation, tests and experiments were carried out on the yarns and then during the making of the fabrics, we measured the initiated tearing of the fabrics. For a better appreciation of the results, a mathematical modeling of this correlation is presented in this work with possible precision errors which are expressed by the relative and absolute errors associated with each equation. The experiments carried out during the work were carried out with multitudes of yarns from different batches and origins.
