Abstract: The effect of different weft twist multipliers on the structural and mechanical properties of plain-woven finished fabrics has been investigated. Fabrics with 5 different twist multipliers in the single weft (3.1, 3.3, 3.5, 4.0 and 4.5) were woven using 2/34s polyester-viscose (65: 35) warp and weft, keeping the other constructional parameters identical. The fabric assistance, fabric strip strength, yarn and fabric tensile strength, abrasion resistance, stiffness, thickness, air-permeability, crease recovery and yarn crimp of the fabrics were determined. With increase in twist level, the yarn packing coefficient and inter-fibre friction increased initially. Beyond the optimum twist level, the fibre rupture reduced the strength and abrasion resistance because of an insignificant contribution of such fibres towards these properties. Similar trends were observed for fabric stiffness, crease recovery, air-permeability, and fabric assistance.
