Abstract: A cellulosic fibrous structure having two regions distinguished from one another by basis weight. The first region is an essentially continuous high basis weight network. The second region comprises a plurality of discrete low basis weight regions. The cellulosic fibers forming the plurality of second regions are generally radially oriented within each region. The cellulosic fibrous structure may be formed by a forming belt having zones of different flow resistances arranged in a particular ratio of flow resistances. The zones of different flow resistances provide for selectively draining a liquid carrier through the different zones of the belt in a radial flow pattern.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

The high basis weight region is subdivided into low density regions, so that a fibrous structure having three regions is produced. In a second embodiment, the fibrous structure has four regions. Both the high and low basis weight regions are further subdivided into high and low density regions. The process comprises applying noncoincident differential pressure to selected regions of an embryonic fibrous structure.

Abstract: A woven papermaking belt having a paper contacting top surface plane and an opposed backside. The belt comprises a fabric having yarns disposed, in part, in the top surface plane to form knuckles. The belt further comprises reinforcing piles extending from a proximal end to a distal end. The distal ends of the reinforcing piles are disposed between the top surface plane of the papermaking belt and the backside of the papermaking belt. The reinforcing piles resist applied loads and may prevent deflection of the knuckles during the papermaking process. The applied loads may either be normal to the belt, as occurs during imprinting, within the plane of the belt, which causes sleaziness of the belt, or both. The belt according to the present invention may have piles with proximal ends disposed at two or more different elevations, as well as distal ends, which are disposed at two or more elevations. This arrangement provides a belt which imprint different densities onto paper during papermaking, according to the ability of the piles to resist compressive loads applied normal to the plane of the belt. In one alternative embodiment, the piles may be disposed between the first and second layers of a multi-layer papermaking belt. The belt according to the present invention is particularly suitable for woven papermaking fabrics having long, unsupported knuckles.

Abstract: The present invention provides a wet pressed paper web. The web has a first relatively high density region having a first thickness K, a second relatively low density region having a second thickness P, which is a local maxima, and a third region extending intermediate the first and second regions. The third region includes a transition region having a third thickness T, which is a local minima. The present invention also provides a method of making a wet pressed web. An embryonic web of papermaking fibers is formed on a foraminous forming member, and transferred to an imprinting member to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web and the imprinting member are then pressed between first and second dewatering felts in a compression nip to further deflect the papermaking fibers into the deflection conduits in the imprinting member and to remove water from both sides of the web. The imprinting member can have a continuous, monoplanar web contacting surface for molding a wet paper web to have a continuous, relatively high density network and a plurality of relatively low density, discrete domes dispersed through the relatively high density network.
