Seam performance of bi-stretch denim fabrics

Abstract

Today, denim garments are generally produced from bi-stretch fabrics due to high level of physical comfort requirements. On the other hand, an important performance that determines the garment quality is seam strength. In order to produce high quality denim garments, the factors that affect the seam strength property must be examined. So, in this study the effect of weave type (Twill 3/1 Z and Twill 2/2 Z) and weft sett (21, 25, 29 wefts/cm) on seam strength and seam efficiency of bi-stretch denim fabrics were studied. Consequently, it is seen that increase in weft sett increases the weft direction seam strength. Weave type has no considerable effect on seam strength and seam efficiency in weft direction whereas a considerably higher seam strength and seam efficiency is obtained in warp direction.
