The effect of Poisson’s ratio on the mechanical properties of fabrics is undeniable. In the present study, a geometrical model for the Poisson’s ratio of two-guide-bar warp-knitted fabrics is developed, based on the presented models in the previous parts of this series. For this purpose, warp-knitted fabrics are categorized into two groups, according to their structures. Thereafter, a geometrical model is presented to predict the Poisson’s ratio of each group. To verify the generated models, theoretical results are compared with the available experimental data. The results show that the generated models are a suitable guidance to consider the Poisson’s ratio of warp-knitted fabrics.
