The Effect of Moisture Contained in Woven Fabric on Its Air Permeability And Porosity

Popis výsledku v původním jazyce

Air permeability and porosity are very important properties of textile fabrics and these properties are strongly related to each other. Another very important property of fabrics is their ability to moisture absorption. During normal use, the textile materials are moisturized due to the sweating. Moisture contained in the fabric reduces its porosity and therefore, it can be expected that it will also reduce its air permeability. This paper presents the results of an experiment which was carried out on a set of fabrics – cotton, polypropylene and cotton/polypropylene blends. Changes in the porosity and air permeability of these fabrics were investigated depending on the portion of the moisture contained in the fabric and also on the portion of the cotton fibres contained in the fabric. It was found that the changes in polypropylene fabrics are only little, conversely the most pronounced changes are in cotton fabrics. The change of the air permeability depending on the percentage of moisture content it is possible to approximate by a second-order polynomial model.
