Patent

CA 2446249

A press felt for use in a papermaking machine comprises a base body, a batt material and a hydrophilic nonwoven fabric, all intertwiningly integrated by needle punching. The batt material comprises a staple fiber, and is composed of a wet paper web side layer and a press side layer. The hydrophilic nonwoven fabric is provided in the wet paper web side layer. The hydrophilic character of the nonwoven fabric improves the movement of water to the nonwoven fabric, and the holding the water in the nonwoven fabric. As a result rewetting is prevented more effectively than in the case of prior press felts.
