Convective Drying of Flat Fibrous Materials.

The kinetics of drying dense wool fabric in different regimes has been studied experimentally. The mass-conducting (diffusion) properties of the fabric are determined depending on the content of moisture in it and its temperature. For the convenience of engineering calculations, the obtained data on the mass conductivity of the fabric are approximated by its dependences on moisture content and temperature. It has been established that the kinetics of convective drying of a dense wool fabric is adequately described by A. V. Luikov's model of heat and moisture transfer subject to the dependence of the mass conductivity of the fabric on its moisture content and the temperature of the drying agent. The proposed approach to the calculation of the kinetics of drying a dense wool fabric, its moisture content, and its temperature can be used in the design of the processes of drying various fabrics.
