FACTORS AFFECTING FABRIC AIR PERMEABILITY
The ability of air to pass through a fabric is known as its air permeability. It directly impacts its wearability. For example, summer fabrics require good air permeability, while winter outerwear should have lower air permeability to ensure windproofness and prevent heat loss. air permeability is crucial for certain fabric applications in defense and industry. For example, parachutes require high air permeability, and tarpaulins must be durable and breathable. Fabric air permeability is determined by the number and size of spaces between [...]
