Determination of the coefficients of the mass transfer and of energy for the drying process of textile, in function of the density of the material

Abstract:

The mass transfer coefficient and of energy coefficient by contact presents during the drying process of a thin textile were determined. Four textile material of different density and experimental data of the drying process were used. The coefficients were determined to evaluate the behavior of each type of textile material in function of the temperature of the cylindrical dryer. The textile materials present densities between 144 y 230g/m2, and the behavior of the transfer coefficients with respect to the temperature of the cylinder is similar to that found for textile with density smaller than 200g/m2 presented higher values of the heat transfer coefficients and lower values of the mass transfer coefficients, compared to the material of higher density.
