The Poisson’s ratio is one of the fundamental properties of any engineering material and presents an essential mechanical aspect of them. The mechanical properties of fabrics as the most common type fibrous materials, especially the Poisson’s ratio, needs to be thoroughly studied. Sometimes the value of Poisson’s ratio obtained for fabrics differs significantly from the other engineering materials, which results in the unique performance of fabrics when subjected to the tensile deformations. Besides, due to the nature and exclusive structure of fabrics compared to the other sheet materials, the measurement methods of Poisson’s ratio and accuracy of the results have been always a matter that required special consideration. A detailed review of different measurement methods of the Poisson’s ratio of fabrics and also the relationship between this property and other physical and mechanical characteristics can be useful for the continuation of researches in this field.
