Abstract: An improved absorbent consumer paper product such as toilet tissue involves drying fabric that forms an aesthetically pleasing and functionally superior pattern on the paper web before creping. The drying fabric is characterized by a plurality of shute threads extending substantially parallel to each other in a cross-direction of the drying fabric; and a plurality of warp threads extending substantially parallel to each other in a machine direction of the drying fabric. The shute and warp threads are woven together so as to define a number of relatively long warp knuckles at locations where one of said warp threads crosses over at least four of the shute threads.
Abstract: The improved creped non-laminar singular web structure comprising long fibers and short fibers demonstrated by high TWA and Z peeling. Creping causes a certain portion of long synthetic fibers and short fibers to substantially be oriented in a predetermined vertical or Z direction across the thickness of the web structure. In particular, when a stratified preparation containing wet stiff CTMP fibers is used, the vertically oriented CTMP fibers increase the total water absorption (TWA) of the web structure without collapsing. The high TWA print/double-creped paper products manufactured from the above web structure are suitable for heavy wipe and dry uses.
Abstract: Disclosed is a method for reducing the moisture content of a paper web in a papermaking process from in the range of 10% to 32% dry to the range of 33% to 50% dry wherein the embryonic web is supported on a knuckled through drier fabric and lightly pressed between the knuckled through drier fabric and a capillary membrane of a capillary dewatering roll. The capillary membrane has capillary pores therethrough which have a substantially straight through, non-tortuous path with a pore aspect ratio of from about 2 to about 20. A vacuum is drawn within the capillary dewatering roll which is not greater than the negative capillary suction pressure of the capillary pores.

Abstract: A centerflow dispenser for dispensing saturated wipers is disclosed which includes a dispensing nozzle affixed to the container of wet wipes. The nozzle has included therewith a rotatable dispensing disk through which the rolled web is dispensed. The rotatable disk has a dispensing orifice therethrough which includes a node and a plurality of contiguous appendages such that the disk will rotate to the path of least resistance as the saturated wipers are drawn through the dispensing orifice regardless of the direction of extraction of the web through the orifice. One or more drain holes are provided through the dispensing disk to allow liquid squeezed from the wiper as it is drawn through the dispensing orifice to pass back into the container. The nozzle includes a funneled or frusto-conical section which collects any liquid squeezed or which may drip from the wiper as it is extracted from the container to thereby direct such liquid toward the drain holes in dispensing disk.
