Abstract	Seam quality is an important factor in determining the durability and performance on the finished garment. As per the established seam quality concepts and theory, this study aims to experimentally investigate the influence of stitch density (SPI) on seam strength in woven cotton fabrics when the stitching is performed using the Industrial single needle lock stitch machine. Two plain-woven cotton fabrics with different structural parameters were stitched using Superimposed Seam (SSa) with spun polyester sewing threads of two linear densities. Stitch densities of 10, 12, and 14 stitches per inch (SPI) were employed. Seam performance was evaluated using standardized tensile testing methods, and statistical analysis was carried out to determine the significance of stitch density on seam behaviour. The results demonstrate that increasing stitch density significantly improves seam strength. The findings confirm the critical role of stitch density in determining seam quality and provide practical guidance for apparel manufacturing and quality control.
