Experimental Analysis of Static Thread Tension on Seam Appearance

Investigate the impact on seam appearance due to fabric weight, bending rigidity and static thread tensions at single needle lock stitch sewing machine. The intersection among the stated parameters is crucial at stitched fabric to predict seam appearance.

Sixteen different weights of fabrics are investigated at fixed foot pressure, needle diameter, bobbin thread tension to explore the effect of intersection.

Present work is suggested that intersection of bending rigidity of fabric and thread has strong linear relationship to magnitude of static needle thread tension at lock stitched sewing machine to predict the aesthetic seam appearance of stitched fabrics.
