Air Filtration means the separation of particles from gas by passing through a permeable medium. Quality of filtration depends upon thickness, air permeability, size of pores, bursting strength and porosity of filtering media. A nonwoven textile material exhibits good filtration property due to three-dimension network of fibers enclosing small pocket of void spaces. In the present work, air permeability property is chosen for study and to access optimal conditions required for air filters. The experiment was carried out with three levels and variables using Box-Behnken design combined with response surface methodology (RSM). Denier of fiber, density of fiber and gram per square meter of fabric were independent variables selected to get desired air permeability of needle punched nonwoven fabric. Data were fitted to a Linear model, model fitness was evaluated by the analysis of variance, which indicates P < 0.0001, R² = 0.83 and coefficient of variance [CV] = 12.53, SD = 24.02. Individual and interactive effects of the independent variables on air permeability were interpreted using the proposed mathematical model and validation of RSM was also done.
