Garment Seam Strength Depending on Needle Size and Stitch Length

Joining patterns into an article of clothing are usually performed using sewing machines where sewing threads are drawn between different material layers making different machine stitches with necessary properties. Appropriate choice of the type of sewn seam, machine sewing stitch, needle and sewing thread allows making joints with accurately specific elasticity and strength. This kind of joining is relatively inexpensive and reliable. Most of the garment seams are subject to forces. If seam strength is small, the seam may break. Each joint should have minimum strength. This paper explores optimal parameters of sewing needle size and the number of seam stitches for three material types in order that a qualitative and strong seam is obtained.
