Abstract
The water vapor sorption — desorption isotherms of a series of natural and chemical fibres were determined and the hysteresis coefficients characterizing the nonequilibrium character of the structure and irreversibility of changes in it in sorption of water vapors were calculated. The moisture sorption — desorption isotherms are described by a single equation for a theoretical-probability model. The coefficients of the TPM equation were found for all types of fibres and can be used for predicting the magnitude of sorption and the change in the properties of textile materials in a wide range of external conditions. The points of the beginning of devitrification of the polymer under the effect of moisture were determined.
