Impact of different stitch types on seam strength and seam slippage

Abstract

The durability of seams significantly influences the overall performance of garments during their intended use. Seam strength is contingent upon multiple factors, encompassing seam type, stitch type, stitches per inch (SPI), sewing thread count, fabric strength, and fabric type. However, among these factors, the stitch type employed in seam creation holds paramount importance. This study aims to ascertain the impact of distinct stitch types on both seam strength and seam slippage. In pursuit of this objective, a fabric with the following construction (EPI: 186, PPI: 131, Warp Count: 32/1 Ne +40D, and Weft Count: 100D + 40D) has been procured. Subsequently, samples have been meticulously fashioned according to the EN ISO 13936-1 method. The seam strength of each sample has been meticulously assessed utilizing a seam strength tester. Throughout this study, diverse stitch types have been chosen, including lock stitch 301, chain stitch 401, double chain stitch 401x2, and overlock stitch 504. The findings encompassing seam strength have been extracted from the corresponding equipment. Comparative analysis of the findings yielded intriguing insights. This proactive approach ensures the production of high-quality apparel items that align with performance expectations and uphold the standard of excellence.
