Composite nonwovens were made by thermal bonding method to examine the validity as the construction materials from needle punched and spunbonded nonwovens. The effects of air permeability, number of layers, porosity and pore size on bonding temperatures were investigated. The air permeability of composite nonwovens was varied with the bonding temperatures. The variation of air permeability was dependent on the nonwoven to have more lower air permeability for 2-layer composite nonwovens. Air permeability of composite nonwovens was influenced by the number of layer. In case of the same weight for multi-layered nonwovens, air permeability coefficients were dependent on the porosity and thickness of nonwovens rather than the weight of nonwovens. Finally, the variation of air permeability of composite nonwovens by puncturing was dependent on the pore size rather than the number of puncture.
