Multilayer creping belt having connected openings, methods of making paper products using such a creping belt, and related paper products
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 overlapping 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.
1. An absorbent sheet having a machine direction (MD) of travel and a cross machine direction (CD) crossing the machine direction, the absorbent sheet comprising:
(a) a plurality of hollow domed regions projecting from a side of the absorbent sheet; and
(b) connecting regions forming a network interconnecting the hollow domed regions of the absorbent sheet,
wherein the absorbent sheet has parallel lines of connected domes running in the MD,
with interconnected connecting regions being formed between the MD lines of connected domes such that each hollow domed region of the plurality of hollow domed regions merges with another hollow domed region in a respective interconnecting connecting region.
