Effect of Air Permeability Characteristics of Protective ...
It seems that air permeability characteristic of clothing material is the major determinant in this respect since it enables better cooling. It can, thus, be concluded from the present data that for clothing material with similar static thermal resistance, the higher the air permeability value is, the lower is the physiological strain, which is in accord with the conclusion made by Havenith et al. (2011) .Get Price Send E-mail
Air Permeability of Woven Fabrics
The air permeability is a very important factor inthe performance of some textile materials. Especially, it is taken into consideration for clothing, parachutes sails, vacuum cleaners, fabric for air bags and industrial filter fabrics. The air permeability is mainly dependent upon the fabric’s weight and construction (thickness and porosity).Get Price Send E-mail
