Abstract: A method for determining the dryness of a fibrous web, in particular a tissue web, during the production of the fibrous web, is carried out in a machine including a drying cylinder, in particular a Yankee cylinder, to which at least one, preferably two, dryer hoods are assigned, and a reel-up for winding up the fibrous web. The determination of the dryness of the fibrous web is carried out before the drying cylinder on the basis of measured values which describe the following variables: the amount of solids in the fiber web at the reel-up, the amount of water in the fiber web at the reel-up, and the amount of water which is evaporated in the dryer hood or hoods. A method for controlling or regulating a machine for producing a fibrous web, a computer program and computer program product are also provided.

Abstract: Soft, durable and bulky tissue products comprising non-wood fibers and more particularly high yield hesperaloe pulp fibers are disclosed. The tissue products preferably comprise at least about 5 percent, by weight of the product, high yield hesperaloe pulp fiber and have relatively modest tensile strengths, such as a geometric mean tensile (GMT) greater than about 1,000 g/3″, and improved durability and cross-machine direction (CD) properties, such as a CD Stretch greater than about 10 percent. Additionally, at the foregoing tensile strengths the products are not overly stiff. For example, the tissue products may have a Stiffness Index less than about 10.0.

Abstract: A fiber structure manufacturing apparatus includes: a defibration unit that pulverizes and defibrates a fiber raw material that contains fibers; a transportation unit that transports a defibrated material after defibration by the defibration unit; a melting-material mixing unit that mixes a melting material into the defibrated material transported by the transportation unit; a fibrous web forming unit that forms a fibrous web by causing a mixture of the defibrated material and the melting material to accumulate; a sheet supplying unit that supplies a shape retainer sheet to the fibrous web; and a heating-and-pressing mechanism that forms a fiber structure by heating and pressing the fibrous web after the shape retainer sheet is supplied; wherein the sheet supplying unit supplies the shape retainer sheet in such a state that nap is raised on a surface, of the shape retainer sheet, that is to be in contact with the fibrous web.

Abstract: A machine for producing a fibrous web, such as a tissue web, has pressing device with a pressing element and a counter-element with a closed surface for forming a pressure nip. A water-absorbing belt with a web side and an opposite pressing element side is guided together with the fibrous web through the pressure nip and the fibrous web is separated at the end of the pressure nip from the web side of the water-absorbing belt and runs further with the counter-element. The water-absorbing belt has at least a first ply and a second ply, and, as viewed in the thickness direction of the water-absorbing belt, a layer in or on the belt half which faces the pressing element, which layer has a higher specific throughflow resistance than the first ply and/or the second ply.

Abstract: Paper products can comprise a first plurality of fibers that are hardwood fibers and a second plurality of fibers that include softwood fibers and surface enhanced pulp fibers (SEPF). The paper product can include one or more first fiber layers that comprise the first fibers, at least one of the first fiber layer(s) defining one of opposing upper and lower surfaces of the paper product, and one or more second fiber layers that comprise the second fibers. When a tissue, by weight, between 50% and 80% of the tissue's fibers can be the first fibers and at least 20% of the tissue's fibers can be the second fibers. The tissue's basis weight can be less than or equal to 21 gsm per ply.

Abstract: Multi-layer substrates comprising top and bottom surface layers comprised of synthetic nonwoven fibers, and a melted thermoplastic material layer between the top and bottom layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F. to 350° F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the top and bottom surface layers that are in contact with the thermoplastic material as it melts.

Abstract: The present invention provides mufti-layered tissue webs, and tissue product comprising the same, comprising long, high-coarseness wood pulp fibers selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing long, high-coarseness wood pulp fibers in one or more outer layers, even in relatively modest amounts, may improve certain product properties, such as durability, without negatively affecting softness. In certain instances, both the softness and durability may be improved by selectively incorporating long, high-coarseness wood pulp fibers in one or more of the outer layers.

Abstract: Methods for forming multi-layer substrates including top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material includes polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F.-350° F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.
