Abstract
A papermaking press felt comprises a base body, a batt layer, and an anti-rewetting layer comprising a non-oriented film, all intertwiningly integrated by needle punching. The anti-rewetting layer has openings with a three-dimensional structure, with an aperture on the paper web side larger than the aperture on the roll side. This press felt exhibits an excellent anti-rewetting effect while maintaining its water removing capability.
