Impact of laundering on the seam tensile properties of suiting fabric Available to Purchase

This paper reports an experimental investigation into the effect of laundering on seam tensile properties with the variation of stitch density, linear density of sewing threads and composition of base material. Tensile properties such as initial modulus, secant modulus, seam strength, strain at fracture and work up to fracture increase with stitch and linear density of sewing threads. The impact of coarser yarn is greater on seam properties of polyester‐cotton fabric than cotton fabric. The tensile properties except seam strain are reduced due to laundering. Reduction in initial modulus and secant modulus due to laundering is higher for polyester‐cotton fabric whereas decrease in seam strength, seam efficiency and strain at break is greater for coarser sewing thread.
