Paper Dryer Fabric Tension Impacts Dryer Performance

Dryer fabrics, often called dryer “felts”, are used to hold paper against the outer surfaces of steam-heated drying cylinders. The pressure from the dryer fabrics increases the rate of heat transfer from the dryer to the paper. The pressure that is applied to the paper depends on the fabric tension and the diameter of the dryer. The pressure can be calculated, as a first approximation, by the equation:
