The production and manufacturing process of textiles are relatively complicated. The clothing that people wear actually undergoes countless processes before they change from cotton or yarn into fabric products. Among them, there are hundreds of types of textile and clothing testing. , For example, to test the performance of air-permeable fabrics.

Under the specified pressure difference condition, the airflow rate that vertically passes through the given area of the sample within a certain time is measured to calculate the air permeability. The airflow rate can be directly measured or converted by measuring the pressure difference between the two sides of the flow aperture.

Test standard: American standard ASTM D737, European standard ISO 9237, Japanese standard JIS L1096.

The ventilation unit can be expressed by mm / s, cm3 / cm2 / s.
