The possibility of applying the approach developed to assess the permeability of water in porous systems of various nature was studied for predicting air permeability in non-woven needle-punched fabrics and processed materials based on polyester fibers with a linear density of 1.7 tex. The application of the proposed approach in predicting the air permeability of fabrics and materials is substantiated. Methods of modeling air permeability are considered and a correlation between the models for assessing the permeability of water and air is established.
