Abstract
In this paper different polyester woven fabrics having different number of filaments in its filling yarns were woven. The effect of the number of filaments on the fabric properties was analyzed. The experimental results were assessed using analysis of variance and regression methods via SPSS statistical package. The statistical analysis revealed that properties of polyester fabrics have affected significantly by the number of filaments. As the number of filaments in the cross section of filling yarns increases, fabric thickness, tensile strength, fabric elongation and crease recovery increases. By the contrast, increasing number of filaments leads to a reduction in fabric air permeability, weight loss due to abrasion and fabric tearing strength. [Mofeda Abdul Rahman AL-ansary.
