Abstract
In this paper, micropolyester woven fabrics with plain, twill and satin weave structures and five different weft densities were produced. Using ANOVA statistical analysis, the effects of weft density and weave structures on the physical and mechanical properties of these fabrics were investigated. The findings of this study revealed that increasing weft density leads to an increase in fabric breaking load, stiffness and crease recovery. On the contrary, the increase in weft density decreased air permeability, and tearing strength. The effect of weft density on fabric breaking elongation and abrasion resistance are similar to each other. Plain weave fabrics were superior to other structures in fabric breaking load, breaking elongation and fabric stiffness. Satin weaves have higher air permeability, whereas twill weaves have higher crease recovery. [Gadah Ali Abou Nassif.
