Fabric Air Permeability Testing Principle
Important factor that affects the comfort of the fabric is the air permeability of the fabric. Sportswear and windproof and coldproof clothing have higher requirements on the air permeability of fabrics. Some industrial textiles, such as aircraft parachutes and filter cloths, have special requirements for the air permeability of fabrics. The air permeability of the fabric is determined by the number and size of the warp and weft yarns and the fiber gap in the fabric, and is also [...]
