What is air permeability?

Air permeability measures how easily air is passed through fabric. It indicates the breathability of weather-resistant and waterproof fabrics and is an important factor in the performance of materials like industrial curtains, sails, airbags and parachutes.


The concept of ‘air permeability’ is widely used in the textile industry to interpret the intrinsic characteristics of fabric. Outdoor garment manufacturers in particular frequently employ this technical information to describe functional performance of products. Air permeability is significantly influenced by a fabric’s material and structural properties, such as shape and value of the pores of the fabric and yarn, which in turn are dependent on the structural parameters of the fabric. The main influences on air permeability are the density of the material and its structure. Fabrics can be coated to modify their air permeability.

 

Application:

Fully Automatic Air Permeability Tester to test the air permeability of various woven fabrics, knitted fabrics, non-woven fabrics, industrial filters, tents, sailcloths, parachutes, raincoat materials, shirtings, downproof fabrics and airbags.

The Feature of air permeability of textile fabrics

Air permeability is the measure of air flow passed through a given area of a fabric. This parameter influences the thermal comfort properties of fabrics to a large extent. It is generally accepted that the air permeability of a fabric depends on its air porosity, which in turn influences its openness. With more porosity, more permeable fabric is obtained.
