Device for Measurement of Static and Dynamic Air Permeability and Deformation Changes in Textile Materials

Abstract

This article investigates the measuring of the air permeability of textiles. A new instrument designed to measure the air permeability of textiles is described in the article. The instrument differs from the standard devices mainly due to the components added, which enable the dynamic measurement of air permeability and give the possibility to investigate the structure of the textile tested during the process of measurement. Individual user settings are described and examples are given of how to process the data obtained. The device is operated by a control program. Contrary to the manual devices, the error introduced by the operating personnel is minimised in terms of setting up the measurement and reading the data measured. The device is controlled by a computer and the data obtained is stored in an electronic form for further processing.

“…Volumetric rate per unit area of the textile at a certain pressure difference is air permeability (ASTM D6476,2017; ASTM D 737, 2018) and it affects the thermal regulation of the human body as well as comfort during wearing (Veselá and Kus, 2016). Both natural and forced convective air pass through the fabric is impressed by the fabric ventilation capacity or its breathability (Tyagi et al, 2010).…”
