Construction factors and finishing techniques have an effect upon air permeability by causing a change in the airflow paths through a fabric. Hot calendaring can be used to flatten fabric components, thus reducing air permeability. The ISO 9237 standard for air permeability testing is vital. It ensures the quality and performance of the tests. The test aims to measure a sample’s air permeability. It does this by measuring the change in pressure at both ends of an orifice plate. . Common air permeability tests are ASTM D737–1996, GB/T 5453–1997, and JIS L1096 .
