Tearing strength is one of the important quality items of finished woven fabrics. It refers to the rupture of a fabric progressively along a line thread by thread. Tearing strength mainly depends on fibre, yarn and fabric characteristics along with mechanical and chemical finishing treatments given to the fabric. From an industry point of view, studying this fabric characteristic is an essential and urgent step because it reflects the endurance extent of the end textile structure. The main objective of this investigation is to examine the effect of twist multiplier (4.1, 4.4 and 4.7) on weft/warp tear strengths for fabric samples of cotton/polyester blend (50:50) using carded and combed spun yarns. In addition, three weft densities being 18, 22 and 25
