  Abstract

The Poisson’s ratio is one of the mechanical properties of fabrics, which is a measure of the deformation during the load exertion. In this research, five groups of spunbonded nonwovens with different areal weights were investigated. These fabrics were subjected to uniaxial extension in the machine direction, bias, and the cross-machine direction. The Poisson’s ratio of spunbonded fabrics has been analyzed considering the effects of two aspects of the areal weight and the loading direction. The results of this study show that at the first stages of extension, the value of the Poisson’s ratio is relatively low, but after the rise of elongation, it increases until reaching a constant value, followed by a decreasing trend, due to the occurrence of the structural jamming. Furthermore, it was observed that the effects of the areal weight and the loading direction on the Poisson’s ratio of nonwoven fabrics were significant at the confidence level of 95%. The value of Poisson’s ratio in the machine direction is greater than the two other directions and with increasing the areal weight, the Poisson’s ratio decreases. Changes in the Poisson’s ratio versus extension and the tensile load follow a Gaussian function with a good approximation.
