SEAM PROPERTIES OF STRETCH FABRICS

Abstract

The paper investigates the longitudinal seam stretching properties on ISO 301 lockstitch seams on garments made of stretch fabric. The influence of factors such as manual manipulation during sewing, stitch density, ply number in the seam and sewing thread extension, was investigated on stretch fabric. The result of planed experiment shows that the ply number thread extension and stitch density are significant factors to seam stretching in seam direction. It was found that the most significant factor on seam stretching in longitudinal direction is ply number. By application of sewing thread of higher extension, the stretching of the lockstitch seams in longitudinal direction of over 100% can be obtained.
