Because of the growing demand for computer aided design and computer display of apparel items for wholesale and retail sale, the need to develop accurate computer simulations of the deformation of apparel fabrics is increasing. The unique combination of low stress mechanical properties (extension, shear, and bending properties) of apparel fabrics results in three dimensional draping properties that are difficult to simulate in a computer program. It is also difficult to represent the dynamic properties of deformation and drape. Fabric deformation is highly nonlinear, requiring the development of highly complex nonlinear computer models. Researchers have developed a universally applicable mathematical model for buckling, folding, and drape properties for textile and apparel fabrics. The model predicts the dynamic behavior, dynamic processing, and tailoring performance of fabrics. Using themodel can aid in the further development of highly accurate computer models for fabric drape and deformation.
