What is "Air Permeability" - Definition & Explanation
The porosity of a fabric as estimated by the ease with which air passes through it. Air permeability measures the warmth of blankets, the air resistance of parachute cloth, the wind resistance of sailcloth, etc. as measured on standard testing equipment.
The permeablity, or the ease with which air passes through material. Air porous ness determines such factors as the wind resistance of sailcloth, the air resistance of parachute cloth, and the effectiveness of different kinds of air filtration media. It is also a measure of warmness, or coolness of a fabric.
The degree to which a fabric, coating or laminate allows air to pass through its construction.
