The bending behavior of woven fabrics under low curvature conditions has been analyzed by linear viscoelastic theory. The fabric is assumed to behave viscoelastically and to be subjected to friction restraints in bending deformation. The friction restraint is considered to be proportional to the curvature and can be described by a friction moment. A model has been constructed by a standard three-element solid model and a paralleled friction sliding element. The equations of the model for a cyclic curvature variation are derived. A set of parameters of the equations for each fabric has been obtained experimentally. The bending rigidity and hysteresis for wool, cashmere, wool/polyester blended, polyester and cotton fabrics have been predicted, displaying that they are in very good agreement with the experimental observations.
