This study was designed to explore the seam performance with special focus on seam strength and efficiency for
commercially obtainable different types of denim fabrics. Technically seam performance is portrayed by strength of
seam, elongation of seam and efficiency of the seam. Seam performance can contribute as an imperative factor in
determining the durability of a garment. Different combinations of denim fabrics were used for seam strength and
efficiency analysis together with four different types of commonly used stitch structures along with three types of
sewing threads like 40, 60, and 80 tex. Seam strength and efficiency for different denim fabrics were changed
consecutively with varying types of stitches combined with increasing stitch density. More specifically, supreme seam performance was observed at light indigo 170 g/m2 (GSM) 100% cotton twill denim fabric for overlock stitch structure alongside higher stitches rather than others. Characteristically the seam line which contains more stitch density encompassed in different denim fabrics demonstrates more seam eminence.
