In this work, based on the geometrical model given in Part I, a mechanical model is created for dry relaxed slack plain knitted technical fabrics including the three-dimensional friction effects. The equilibrium of forces and moments applied on a loop are written by using the elasticity theory of thin rods. Through this model, it is shown that a dry relaxed plain knitted fabric can be in a stable state induced by friction. The application of the model was carried out on E-glass technical fabric, which was also used in Part I as its dimensional properties were obtained through the created geometrical model. In the current part, Part II, the mechanical properties of this fabric are obtained and discussed as an exemplary application.
