Breathability

 Breathability - is one of the properties of the fabric, the material's ability to pass air. The value of air permeability depends on the presence and amount of tissue in the long - more than them and they are larger than, the air permeability above. According to this criterion tissue is separated in accordance with the purpose of use. Most high permeability must have linen and dress fabrics, and low - woolen, woolen fabrics, fabrics for outerwear. The quantity of air permeability is determined by using special devices that use the thin air.
