Patent CA-2402661-A1 (CA)
Title: Papermaking press felt
Inventor: WATANABE KAZUMASA
IPC: D21F7/08
Filed: 2002-09-11
Abstract: A papermaking press felt having excellent rewetting suppression without impaired water-squeezing capability.  comprises a base body, batt layers, and a rewetting prevention layer, integrated with one another by needle punching. The rewetting prevention layer has three dimensional passages comprising a verge opening, a wet paper web side opening and a roll side opening. The wet paper web side opening is larger than the roll side opening. Under nip pressure, water from the wet paper web moves into the roll surface side of the felt, passing through the passages in the rewetting prevention layer.  Although a rewetting phenomenon tends to occur when the press felt is released from the nip pressure, movement of water through the passages back to the wet paper web side of the felt is suppressed since the roll side openings are narrower than the wet paper web side opening.
