Simulation of Sewing in Lapel Part using Blind-stitch Sewing Machine and A Relation between Sewing Factors and Configuration of Lapel

We examined the bending property of fabric blind-stitched with interlining and verified that the bending rigidity and 2HB by KES system changed with the amount of needle penetration and the spacing between stitch lines. As a simulation of lapel sewing using optional outer fabric and interlining, the sewing condition for blind-stitch machine was set up by using the results obtained in the previous paper. It was shown that the actual amount of needle penetration agreed well with the predicted one, indicating that the simulation was very useful. It was also shown that the configuration of stitched lapel was effected by sewing factors such as the amount of needle penetration and the spacing between stitch lines.
