Abstract:
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.
