Geometry of plain weave fabric under shear deformation. Part II: 3D model of plain weave fabric before deformation

The main attempt of this investigation is to establish a model for evaluating internal geometry of woven fabric. A new concept about packing density of yarns inside of fabric is putted in forward and then internal geometry of fabric before deformation is predicted by common data of a fabric. A numerical analysis has been performed for two kinds of actual plain weave fabric on the basis of proposed model. The geometrical specifications of these fabrics are successfully evaluated. This model is to be expanded for predicting shear deformation of fabric in subsequent Part III (Kamali Dolatabadi & Kovar, 2009b).
