Article

The proposed model has limited use for evaluating the effect of the needle-punching and calendering regimes on the air-permeability of the material. It is somewhat difficult to correct the model to consider the effect of changes in thickness during needle-punching and calendering. The limited use of the model is due to the use of the filling factor and thickness of the material as the structural parameter.
