Anisotropy of fabrics and fusible interlinings

As CAD fabric modelling becomes more widespread there is a need to study the applicability of fabric property parameters which are used in predicting fabric behaviour. The anisotropical mechanical behaviour of woven fabrics, fusible interlinings and their composites were studied on order to invesigate the accuracy of equations used to predict the anisotropic linear elastic behaviour of fabric for in plane and bending deformation. Bending, shear and tensile properties were measured using KES©F equipment. Results showed that the orthotropic model of anisotropy can be applied for the qualitative modelling of woven and fusible interlining fabrics and that simple mechanical models for bending properties can be used for their composites.
