Textile Fabric Air Permeability Testing Machine ISO 9237/ASTM D737/BS 5636
ISO 9237/ASTM D737/BS 5636 Textile Fabric Air Permeability Testing Machine
Application:
Air permeability is an important factor in the performance of such textile materials as gas filters, fabrics for air bags,
clothing, mosquito netting, parachutes, sails, tentage, and vacuum cleaners. In filtration, for example, efficiency is directly
related to air permeability. Air permeability also can be used to provide an indication of the breathability of weather-resistant and rainproof fabrics, or of coated fabrics in general, and to detect changes during the manufacturing process. In specialty, industrial and military applications, it can play a vital role in protection. In every market, satisfying the demands of consumers and producers requires ways to accurately and repeatably test material air flow.
Usage:
To determine the resistance of fabrics (woven, knitted and nonwoven textile materials) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area.
Standard:
GB/T 5453 Textile fabrics - Determination of permeability
