Air permeability behavior is an important property with an indisputable influence on the application of fabric for technical purpose and clothing applications. The simple method to study air permeability is testing fabric sample under standard condition using the appropriate developed testing equipments. However, simulation of this property is obligatory in the production of woven textile with prescribed air permeability. Among various approaches, numerical methods are considered useful because of the accurate results obtained. For this reason, in this paper a three-dimensional simple model of warp and weft yarns interlacing was drawn and air permeability behavior of plain woven fabrics was simulated in accordance with the experimental conditions. Fabric constructional parameters required to draw a unit cell of the fabric were calculated using Peirce's structural model for plain woven fabric. Comparing the experimental results and data derived from numerical model showed that, it is possible to simulate air permeability in plain woven fabrics by numerical approach. In addition, minimum and maximum numerical prediction errors were 3.41% and 20.92%, respectively.
