AN APPROXIMATE ANALYSIS OF DRYING OPERATION OF WET FABRIC

This study describes an approximate theoretical analysis of drying a m oving wet fabric exposed to constant radiant heat and hot air blown no rmal to its surface. By considering the problem as a combination of he at and mass transfer processes, the governing dimensionless groups are identified and their influence on the residence time is established. These groups are then utilized in the prediction of either the residen ce time or the total length of travel needed to achieve a specific dry ing level of the fabric.
