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.

Press felt for papermaking

A press felt for papermaking comprises a base body, a fibrous assembly, and a three-dimensional knitted fabric within the interior of the felt. The base body and the knitted fabric may be in contact, or, for improved adhesion between the base body and the knitted fabric, a fibrous assembly may be disposed between the base body and the knitted fabric. Excellent compression recoverability and sustainability may be obtained.
