Abstract
The article considers the problem of predicting the moisture exchange of textile materials in a wet state using the example of knitted fabrics for underwear. Based on the thermodynamic analogy of heat and moisture transfer processes, an experimental scale of the moisture transfer potential of a reference body was constructed. As a result of the study of the mass transfer system “sample – reference body”, the mass transfer characteristics of several knitted fabrics were obtained. Thermodynamic relations are obtained for calculating the intensity of moisture transfer of textile materials in a bag of clothes. The results of calculations are given on the example of the selected samples. The results of the calculations made it possible to establish the relation- ship between the moisture flux density from the sample and the value of the moisture transfer potential. Signifi- cant differences between these flows have been established. The data obtained make it possible to make a fore- cast about the operational efficiency of clothing with various options for the material of the linen layer.
