A model of fabric bending that includes a nonlinear elastic contribution, a viscous friction contribution, a Coulomb friction contribution, and a hysteretic contribution is presented. These are combined to recover the loading, unloading and hysteresis behaviors observed in the bending tests performed under the Kawabata Evaluation System. Results of the model and its components are compared and contrasted with experimental results. It is found that inertial effects dominate the behavior of the model in the early stages of the KES test and that, once the static friction threshold is overcome, friction arises from the slipping of the yarns with respect to each other. The results show that nonlinear elastic behavior arises from jamming of the yarns and their subsequent compression.
