4. Air permeability prediction methods

4.1 The benefits of air permeability prediction methods

The prediction of air permeability is of interest in technical textiles, where objective values of this characteristic are expected. The textile industry is looking for trends or ranges of permeability values to match the applications in question.

Prediction can involve textile complexes made up of several layers of fabric, as in the case of protective clothing for workers or sportswear. The "multi-layer" principle is used, for example, for protection against cold, heat, fire or chemical hazards
