Abstract

The objective of this paper is to calculate the heat of desorption of moisture during the drying of textile materials, using the Othmer method, which correlates steam pressure and the latent heat of vaporization. Data from the literature were used for the desorption isotherms of two different textile material types (denim and cotton-elastane). The results obtained presented the amount of energy required for desorption of moisture linked to the fiber of textile materials during drying. As the amount of free moisture decreases, the amount of energy required for the process of desorption increases. The equation determined to obtain the heat of desorption, as a function of equilibrium moisture, presented a correlation of 0.999 for both textile materials, which indicates quality in the obtained parameters.
