Presenter(s)

Air permeability is an important property for the evaluation of the performance of apparel and technical textile fabrics, including nonwoven fabrics.  A fabric's air permeability is a measurement of how well it enables air to move through it and is of importance for a number of end uses such as industrial filters, tents, sailcloths, parachutes, raincoat materials, sportswear, shirtings, downproof fabrics and airbags. 

 

This webinar will look at a general overview of air permeability, the importance of testing, and how to test in a way that is repeatable and accurate.  It will focus on two standards:

  • EN ISO 9237 - Determination of the permeability of fabrics to air
  • ASTM D737 - Standard Test Method for Air Permeability of Textile Fabrics

 

Course Outline:

  • What is air permeability and why the test is important and useful. 
  • A general overview of the tests according to EN ISO 9237 and ASTM D737. 
  • Potential issues during testing. 
  • What other standards are also applicable to Air Permeability. 
  • Q & A
