摘要： A cellulosic sheet includes a single ply providing a first surface of the cellulosic sheet on one side and a second surface of the cellulosic sheet on a second side. The single ply has a caliper of at least about 130 mils/8 sheets, a basis weight of less than about 16 lbs/ream, and a dry machine direction/cross machine direction (MD/CD) tensile ratio of less than about 1.0.

摘要： An absorbent sheet made by a process that includes the steps of forming a nascent web from an aqueous papermaking furnish, and creping the nascent web on a multilayer belt that includes (i) a first layer made from a polymeric material having a plurality of openings, and (ii) a second layer attached to the first layer, with the nascent web being deposited onto a surface of the first layer. The absorbent sheet includes a plurality of hollow domed regions projecting from a side of the absorbent sheet, with each of the hollow domed regions being shaped such that a distance from at least one first point on an edge of a hollow domed region to a second point on an edge at an opposite side of the hollow domed region is at least about 0.5 mm.

摘要： An absorbent cellulosic sheet made by a method that includes forming an aqueous cellulosic web on a portion of a structuring fabric in a papermaking machine, and drying the cellulosic web to form the absorbent cellulosic sheet. The portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of at least about 26. The absorbent cellulosic sheet has a caliper of at least about 160 mils/8 sheets and a dry machine direction (MD) to cross machine direction (CD) tensile ratio of less than about 1.0.

摘要： A system for fabricating a sheet product. A first rotatable roller includes a rotatable drum portion having an outer surface that rotates about a rotational axis in a first direction and conveys a sheet product. The rotatable drum portion also has a plurality of ports communicative between an inner surface and an outer surface. The ports extend along and around the drum portion. The first rotatable roller emits a pressurized fluid. A second rotatable roller has an outer surface arranged proximate to the outer surface of the rotatable drum portion of the first rotatable roller, and a heat source portion to heat the second rotatable roller to dry the sheet product. The second rotatable roller rotates in a second direction that is opposite to the first direction. A gap is defined between the second rotatable roller and the first rotatable roller through which the sheet product passes.

摘要： An absorbent cellulosic sheet made by a method that includes forming an aqueous cellulosic web on a structuring fabric in a papermaking machine, non-compactively dewatering the cellulosic web on the structuring fabric, and drying the cellulosic web to form the absorbent cellulosic sheet. A portion of the structuring fabric on which the cellulosic web is formed has an adjusted planar volumetric index of at least about 27.

摘要： A method of creping a cellulosic sheet and a creped web made by a creping process. The method includes preparing a nascent web from an aqueous papermaking furnish, depositing and creping the nascent web on a multilayer creping belt that includes (i) a first layer made from a polymeric material having a plurality of openings, and (ii) a second layer attached to a surface of the first layer, with the nascent web being deposited on the first layer, and applying a vacuum to the creping belt such that the nascent web is drawn into the plurality of openings, but not drawn into the second layer.

摘要： An absorbent sheet of cellulosic fibers that has an upper side and a lower side. A plurality of hollow domed regions projects from the upper side of the absorbent sheet. Each of the hollow domed regions is shaped such that a distance from at least one first point on an edge of a hollow domed region to a second point on an edge at an opposite side of the hollow domed region is at least about 0.5 mm. Connecting regions form a network interconnecting the hollow domed regions of the absorbent sheet. A singly-ply of the absorbent sheet has a caliper of at least about 140 mils/8 sheets.
