Evaluation of Sewing Performance of Plain Twill and Satin Fabrics Based On Seam Slippage Seam Strength and Seam Efficiency

Seam strength is an important factor in determining the durability of a garment.Seam strength is determined by resistance to pulling force and abrasion.Seam tenacity break the fabric or the weakest stitch of seam.Seam abrasion resistance is the amount of rubbing action needed to wear away stitches in the seam strength is related to stitch type, thread strength ,thread tension, seam type,seam efficiency, width ,and stitches per inch.Loop strength of thread is more important to durability the seam need not be stronger than the fabric being sewn.A triple stitched lapped seam would not be necessary for a pair of corduroy jeans since the fabric itself is not strong and would wear out before the seam.It is better to have the thread is an overstressed seam that to damage the fabric.Our project objective is to find the seam of strength by using different type of materials.
