CORRELATION BETWEEN TOTAL FRACTIONAL COVER AND WARP BREAKAGE

In this study, the influence of total fractional cover on warp breakage during weaving is investigated by weaving plain and 1 3 twill structure with finer cotton yarns. For this purpose, we have taken cotton yarns of three different count and determined the total fractional cover for the constant value of EPI and varying the PPI for the same count of warp and weft yarn. The PPI is increased for the same EPI until frequent warp breakage occurred during weaving. While the value of total fractional cover increased by the value of PPI, the warp breakage increased with higher total fractional cover value. It was also found that higher fractional cover was attained with 1 3 twill structure without frequent warp breakage compared to the plain structure. This study shows too high total fractional cover disrupts weaving performance with frequent warp breakage.
