Hydrothermal Properties of Cotton and Wool Fabrics Containing Chemical Fibers

Abstract

We pr esent an equation for analytical determination of the mass conductivity coefficient, obtained on the basis of the macroquantum thermodynamic method. Such an approach has allowed us to develop an engineering method for qualitative analysis and design of hydrothermal processes, in particular in materials and articles for textile and light industry. To test the equation obtained, we have conducted an experimental study of the mass conductivity of cotton and wool fabrics. We present a flow chart for calculation of the mass conductivity coefficient. In recent decades, a new approach has been recognized and steadily developed in physics for describing thermodynamic behaviors in processes: macroquantum physics. This approach is based on the principle of the substantiality of energy [1-3], and also the concept of macroquantization of thermodynamic parameters [4, 5]. A number of scientific results have shown that this approach is reasonable and very fruitful [5-7]. As applied to thermophysical processes of heat and mass transfer, such an approach has made it possible to develop an engineering method for qualitative analysis and design of hydrothermal processes, in particular, in materials and articles for textile and light industry [7]. We have obtained an equation for analytical determination of the mass conductivity coefficient for materials over a wide range of variation in the structural characteristics [λ m , kg/(m·s·Pa)]: , 2 2
