Resumo: 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.

Foram utilizados dados da literatura para as isotermas de dessorção de dois diferentes tipos de materiais têxteis (sarja e meia-malha). Os resultados obtidos apresentaram a quantidade de energia necessária para a dessorção da umidade ligada à fibra dos materiais têxteis durante sua secagem. À medida que a quantidade de umidade livre diminui, a quantidade de energia requerida ao processo de dessorção aumenta. A equação determinada para a obtenção do calor de dessorção, em função da unidade de equilíbrio, apresentou uma correlação de 0,999, para ambos os materiais têxteis, para indicar qualidade nos parâmetros obtidos.Universidade Estadual De Maringá2009-11-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/102510.4025/actascitechnol.v32i1.1025Acta Scientiarum.
