Evaluating Models for Predicting the Air Permeability of Needle-Punched Nonwovens

  • Published:
Fibre Chemistry Aims and scope

An analysis is made of effective models that have been proposed for predicting the air permeability of needle-punched nonwovens in accordance with the requirements of the Russian standard. An approach that entails constructing models with a single structural parameter is suggested. The parameter can be thickness, surface density, volumetric density, or the space factor. The given approach precludes obtaining models with one correction factor. Models constructed with two correction factors make it possible to predict air permeability for certain values of the structural parameters. The optimum model uses surface density as the structural parameter.
