Abstract

A micropore drying apparatus (10) comprising a micropore drying medium(15) having a wet flow resistance to air flow therethrough that decreases in the machine direction optimizes energy consumption compared to known micropore drying apparatuses, which do not exhibit a decreasing wet flow resistance to air flow in the machine direction. In addition to the micropore drying apparatus (10), a process for drying a web using the micropore drying apparatus.
