Abstract

A three layer papermaking press section press felt in which the first layer comprises a core fabric which contains the mechanical loads placed upon the press felt, the second layer comprises a layer of absorbent material, typically a batt needle punched onto the core fabric, and the third layer comprises a porous layer attached to the surface of the absorbent layer. The third layer receives the wet paper web. The three layer press felts remove from about 3% to at least about 5% more water from the wet paper web under pressure in a press section in comparison with the same press felt to which the third porous layer has not been added.
