  • Patent number: 9371615
    Abstract: A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web having an apparently random distribution of papermaking fiber. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is fabric creped from the transfer surface utilizing a patterned creping fabric. The fabric creping step occurs under pressure in a fabric creping nip defined between the transfer surface and the creping fabric. The creping fabric contacts the transfer surface and applies pressure to the web against the transfer surface such that the fibers of the web are redistributed on the creping fabric to form a web with a drawable reticulum having a plurality of interconnected regions of different local basis weights.

  • Patent number: 9279219
    Abstract: An absorbent cellulosic sheet having a variable local basis weight. The sheet includes a papermaking-fiber reticulum having a plurality of fiber-enriched pileated regions of a relatively high local basis weight each extending a distance in a cross-machine direction (CD) of the sheet, and a plurality of elongated densified regions that interconnect the plurality of fiber-enriched pileated regions. The elongated densified regions (i) have a relatively low local basis weight, and each extending a distance in a machine direction (MD) of the sheet, and (ii) are arranged in a repeating pattern having leading and trailing edges, such that the elongated densified regions are longitudinally staggered with respect to each other.

  • Patent number: 8568560
    Abstract: A method of making a cellulosic absorbent sheet. A cellulosic web is prepared from an aqueous papermaking furnish. The web is fabric-creped.
