In the textile industry there is great interest in evaluating the air permeability in
textiles and non-textiles, since this property has important applications such as
thermal insulation, protection against wind, or properties related to comfort of
the garments. This is why it is important to evaluate the air permeability in textile
materials. The hot wire anemometry technique allows obtaining the flow
velocity profiles both in air and water and that is why, by means of these profiles,
it is possible to evaluate the air permeability in this type of materials. In the
present work the hot wire anemometry technique is implemented to evaluate
the coefficient of air permeability in textile barriers. Among the results found, a
non-linear decrease in the coefficient of air permeability is observed when the
textile coverage factor is increased.
Keywords: textile barriers, velocity profiles, anemometry
