Air Permeability is the resistance of fabrics (woven, knitted and non woven textile materials) to the passage of air under constant preset air pressure. Air permeability is an important property of some textile materials. The air permeability is mainly dependent upon fabric's weight and construction (thickness and porosity).
Air permeability tester TQD-G1 conforms to the multiple national and international standards:
TQD-G1 is professionally applicable to the determination of air permeability of decorating materials used in cars, e.g. polyurethane, expanded plastics, PVC, leather, textiles, non-woven and other materials.
