ABSTRACT
In this study the author analyzed the effects of sewing thread count on seam strength. In this study different types of seam classes (Superimposed Seam, Lapped Seam & Bound Seam) were produced by using different sewing thread counts (Tex-27, Tex-60, Tex-80 & Tex-120) and Stitch Class-300 (Lock Stitch) was used to produce the seams keeping the Stitch Per Inch at 4.5. Here seam strengths of different seams were determined by using Titan Universal Strength Tester and ASTM D1683-04 method was used to determine seam strengths. After completing the research work, it was found that seam strength increased with the increment of sewing thread count for same seam class. But the suitability of the sewing thread countchanged with the variation in thread size whendifferent seam classescame into account.
