The influence of axial straining on the tensile characteristics of compact yarns is the main focus of this study. The tensile characteristics studied include breaking force, breaking elongation and breaking work. The tensile tests were carried out at different strain rates and gauge lengths on yarns produced with and without compactness of 60s count. Then individual load extension curves are drawn for the yarns at all strain rates and gauge lengths using Meredith experimental procedure and the slope values are measured at three regions of each and every curve. As the strain rate increases the tenacity increases for both the yarns of 6lfs count (With and without compaction), where as the breaking extension increases up to certain level and at higher strain rate it decreases. As the gauge length increases both tenacity and breaking extension decreases and as the strain rate increases the slope value increases for both the yarns, but as gauge length increases the slope value decreases for both the yarns. From the individual graphical analysis it has been found that the, variations in slope are found to exist in yarn without compactness. The variations are minimized in yarn with compactness.
