Absorbent sheet made by creping a nascent web on a multilayer belt having openings

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.

RESILIENT HIGH BULK TISSUE PRODUCTS

The present invention provides tissue webs and products that are manufactured by non-compressive dewatering and/or drying methods, such as through-air drying, where the webs and products comprise cross-linked fiber. The non-compressively dewatered tissue webs and products have improved sheet bulk and z-direction properties. For example, in one embodiment, the invention provides through-air dried tissue products having good sheet bulk and resiliency, such as a sheet bulk greater than about 15 cc/g and Compression Energy (E) greater than about 1.30 N/m. Surprisingly the foregoing products have sufficient strength to withstand use, such as a GMT greater than about 600 g/3, but are not overly stiff, generally having a Stiffness Index less than about 12.

Absorbent sheets having high absorbency and high caliper, and methods of making soft, absorbent sheets

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.

Fibrous structures and methods for making same

Fibrous structures that exhibit a novel combination of properties and to methods for making such fibrous structures are provided.

Method of making a structured fibrous web and a creped fibrous web

The invention relates to a method of making a structured fibrous web (W). The method comprises forming a fibrous web (W) and conveying the formed fibrous web on a water receiving felt (5) to a dewatering nip (PN) formed by a first press unit (8) and a second press unit (9) and where an endless belt (11) is passed through the nip together with the fibrous web 5 (W) and the water receiving felt (5), The endless belt has a side which is covered by a polymer and which contacts the fibrous web (W) in the dewatering nip (PN). After the dewatering nip, the web (W) is transferred with a speed difference to an endless structured clothing (12) which is permeable to air and has protruding knuckles (40) on the side that contacts the fibrous web (W) and which protruding knuckles (49) give the structured clothing (12) a topographic surface 10 area which, for a given length of the structured clothing (12) in the machine direction and a given width of the structured clothing in the cross machine direction, exceeds the plain surface area of a part of the endless belt (11) having an equal length and width. The structured clothing is operated at a speed which is so much lower than the speed of the endless belt (11) that the relative difference in speed between the endless belt (11) and the structured (12) fabric 15 corresponds to the relative difference in surface area between the endless belt (11) and the structured clothing. In this way, the fibers of the fibrous web (W) will be evenly distributed on the structured clothing (12). The invention also relates to a creped fibrous web (W) having a basis weight in the range of 14 g/m.sup.2-40 g/m.sup.2, and having a three-dimensional structure formed by depressed regions (45) and elevated regions (46). The fibers of the fibrous web (W) are 20 evenly distributed over the surface of the creped fibrous web (W).
