Pressfilz zur Papierherstellung

摘要

A papermaking press felt (10) comprises a base body (30), a batt layer (20), and an anti-rewetting layer (40) comprising a non-oriented film, all intertwiningly integrated by needle punching. The anti-rewetting layer has openings (44) with a three-dimensional structure, with an aperture on the paper web side (42a) larger than the aperture on the roll side (42b). This press felt exhibits an excellent anti-rewetting effect while maintaining its water removing capability.
