Abstract

The article presents a new method for calculating the drying process of fabrics based on the A. Lykov’s and G. Filonenko’s equations of drying kinetics. Experimental data on convective and convective-radiation drying of various fabrics are processed. The equations are given for determining the densities of heat fluxes, the intensity of moisture evaporation, and the temperature for the period of falling drying rate. The equations for determining the duration of drying of fabrics are presented. The values of heat transfer coefficients and Bio numbers for different tissues are calculated. It is shown that the number of Bio when drying fabrics is less than one, and the main limiting factor is the external heat and moisture exchange of the surface of evaporation of moisture from the surface of the material with the environment. Verification of the reliability of the obtained computational equations and comparison of the calculated values with the experimental ones are presented. The mismatch values are within the acceptable limits of the accuracy of the experiment and processing.
