Краткое описание

Moisture movement in a porous medium is a process that occurs in many engineering applications. These include moisture movement in soils, nutrient uptake by plants, drying of food, and petroleum extraction. This process is also of special interest to the textile industry. The mechanisms of water vapor transmission through textile fabrics are not well known. The rate at which they are able to transmit water vapor is most often measured under standard textile testing conditions of 20° C and 65% relative humidity. The experiments described in this article are designed to measure the effect of the temperature and the humidity gradients on water vapor resistance of these fabrics. Experiments involve relative humidities of 40%, 50%, and 70% with the temperature held at a constant 30°C throughout and temperatures of 25, 30, and 35°C with the relative humidity held at a constant 50% throughout.
