The rate of air flow passing perpendicularly through a known area of fabric is adjusted to obtain a prescribed air pressure differential between the two fabric surfaces. From this rate of air flow, the air permeability of the fabric is determined.
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.
TQD-G1A Air Permeability Tester is applicable to the test of air permeability and air resistance of automotive interior decoration materials, such as polyurethane foam, PVC, leather, textiles, nonwovens etc.
