A new mechanical model is proposed in this paper to evaluate the shearing properties for woven fabrics during the initial slip region. Compared to the existing mechanical model for fabric shear, this model involves not only bending but also torsion of curved yarns. This model has the advantage of taking into consideration the yarn undulation in fabrics while keeping mathematical rigor. Moreover, an erroneous formula in the previous research work from a referenced paper is modified. Analytical results show that this model provides better agreement with the experiments for both the initial shear modulus and slipping angle than the existing model. The approach for this model can be extended to predict other mechanical properties of fabrics in order to obtain more precise results. (C) 2004 Elsevier Ltd. All rights reserved.
