  • Patent number: 11746473
    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.

  • Patent number: 8679292
    Abstract: A method is conceived for producing hydrophobic lignocellulosics based on the graft copolymerisation of vinyl-type monomers onto the lignocellulosic backbone initiated by a redox couple initiator in aqueous medium. The green modification process can be carried out on any lignocellulosic material, for example, chemical, chemi-thermomechanical or thermo-mechanical pulps, bleached or unbleached. The technology disclosed in this invention yields individual lignocellulosic entities, for instance, hydrophobic pulp fibers, that can be used in combination with other fibers or polymers to produce nonwoven fibrous materials or composites. A significant aspect of the invention is that the modified lignocellulosic material possesses an efficient hydrophobic barrier and minimum interfacial energy to generate optimum adhesion when introduced to polymer resins.

  • Publication number: 20100147473
    Abstract: Tissues are provided as multi-ply tissue products having greater tactile sensation and resiliency in hand. Improved tissues may have a thickened and reduced density middle layer. The tissues may serve as applicators for chemical agents to be released during use of the tissue. A tissue having an improved tactile impression to the consumer, with enhanced resilience and high external bulk is disclosed. In one embodiment, a multi-ply structure having at least three plies is desirable. A middle or intermediate ply is comprised an increased thickness and a greater bulk is employed. In general, the exterior plies of the tissue are smooth and desirable to the consumer.

  • Patent number: 7662257
    Abstract: A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking whose fiber orientation is biased along the direction between pileated interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.

  • Patent number: 7662256
    Abstract: The present invention is generally directed to paper products having great softness and strength and methods of making the paper products. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side.

  • Patent number: 7648772
    Abstract: A sheet of cellulose based material having enhanced strength, particularly the dry strength, substantially unaffected repulpability is disclosed. The sheet of cellulose based materials generally includes a first cellulose based material connected with a second cellulose base material element. The first cellulose based material is formed by separating a portion of the fiber from a furnish, treating the separated portion with a cationic wet strength resin which is allowed to bond to the fiber. The treated fiber is them mixed with the untreated balance of the fiber at some point before the paper machine. The fiber that is separated may be secondary fiber, virgin fiber or combinations thereof. The second cellulose base material element is substantially free from any treatment. The second cellulose base material element may be include substantially all untreated fibers.

  • Patent number: 7563344
    Abstract: Wet-pressed creped tissue sheets exhibit continuous undulating valleys separated by continuous mono-planar macro-ridges running in the machine direction of the sheet, the macro-ridges being of a lower fiber density relative to the fiber density of the undulating valleys. The tissue structure can be created by pressing a densified tissue web against the surface of a Yankee dryer while the web is supported by a texturizing (molding) fabric having a web-supporting surface having highly topographic continuous or substantially continuous ridges and valleys and thereafter creping the web.
