Document Type and Number:
Japanese Patent JP2007516365
Kind Code:
A
Abstract:
A press felt for use in the press section of a papermaking machine is provided. The press felt includes a base fabric layer and at least one layer of a staple fiber batt material connected thereto. The press felt has a paper side surface (PS) which when in operation is in contact with a paper web conveyed thereon and a machine side surface (MS) which contacts various press section components. The base fabric layer includes a regenerated cellulosic component in either or both the MD and CD yarns. Regenerated cellulosic fibers may also be provided in the batt and/or scrims located in the batt to improve dewatering when compared to similarly constructed felts which lack this regenerated cellulosic material.
