In the textile and clothing sector, air permeability is important for the exchange of air between the inner layers of clothing and the environment.

This will substantially influence the wearing comfort of clothes. Air permeability is also important for drying after washing. In the technical sector, it plays a role in air and gas filters – or with air bags in the automobile industry.
