Sažetak
When tensile force acts on woven fabric samples, unwanted plastic deformations and tearing of the fabric may occur. In order to avoid the occurrence of plastic deformation in the fabric, the elasticity limit and the yield point of the material should be known. For this purpose, raw cotton woven fabrics have been deposited in the plain and in the twill weave with same warp density and different weft densities. From the obtained force-elongation curves, for all weft densities, when force acts in warp and in weft direction, the elasticity limit and the yield point were determined. This paper analyzes the impact of weft density change on values of maximum force, breaking force, force at the yield point and force at the limit of elasticity. When the force acts in the weft direction, as the weft density increases, so do the values of the elasticity limit and the yield point. Fabrics in a plain weave with a higher weft density have a greater possibility of elastic and elastoplastic deformation, than fabrics in a twill weave.
