The effect of the mechanical properties on the MIT drape behaviors of fabrics are investigated by experiment and simulation. An improved MIT drape device enables us to detect the drape shapes of fabrics specimens with higher reproducibility than that of earlier authors. The large deformation of a fabric sample under drape is simulated by a non-linear FEM combined with an incremental method, where the sample is modeled by an elastic thin shell. The computed results and observed ones suggest that the simulation is valid for the estimation of the real MIT drape properties of fabrics, and that the MIT drape characteristics of fabrics depend appreciably on the bending rigidity and torsional one but little on the extensional rigidity and shearing one.
