The tensile strength of woven fabrics is influenced by several factors, the most important of which are the type of material, the nature of the composition of the warps and wefts, the number of twists, the density of the warps and wefts per measurement unit and the weave construction. There is number of studies that dealt with these factors either separately or in combination and their effect on the tensile strength and elongation of woven fabrics.
The present study deals with the effect of the multiple layers of woven fabrics and the interlining ratio of these layers on tensile strength and elongation of these fabrics. Fifteen research experiments were conducted with three different weave constructions and three differences in the layers and the interlining ratio. The experiments proved that there is a statistical relationship between the effect of the interlining ratio and the multiple layers on both tensile strength and elongation.
