Abstract

During high speed sewing, needle thread is subjected to dynamic loading, inertia forces, friction and repeated tensile stresses at tremendous rates. The value of these stresses depends upon stitching speed, sewing thread tension, stitch length and sewing thread properties. These parameters affect the tensile properties of sewing threads adversely, leading to loss in seam strength. In this study, the effect of various parameters lubrication (%), stitch density, the number of fabric layers and stitching speed on tensile properties of sewing thread has been studied using Box- Behnken design. Contrary to the popular belief, loss in tenacity increases as stitching speed increases. 4% lubrication (%) is suggested to get minimum tenacity loss (%).
