  • Patent number: 7749356
    Abstract: Pulp fibers can be treated with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after redispersing the treated pulp fibers in the process water. One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a water insoluble chemical additive thereby forming a chemically treated dried fibrous web containing chemically treated pulp fibers.

  • Patent number: 7661552
    Abstract: By interfolding or interleaving at least a portion of the dispensing panel of a dispenser with the first sheet in a stack of sheet material such that a leading edge of the first sheet is exposed, it is no longer necessary to reach into the dispenser to dispense the first sheet. To dispense the first sheet, the optional removable panel is torn from the dispenser, and then the already exposed leading edge of the first sheet protruding from the dispensing panel is grasped and pulled to withdraw the first sheet from the dispenser.

  • Patent number: 7625462
    Abstract: Polymeric bonding agents having a “triggerable” bonding functionality and which are in the form of particles or fibers, are blended with papermaking fibers prior to formation of a tissue web. After the web is dewatered, and advantageously during or after drying, the triggerable bonding functionality is activated to strengthen the resulting sheet structure. Tissue sheets prepared in this manner can exhibit an improved combination of softness, bulk and strength.

  • Patent number: 7588662
    Abstract: Soft tissue products with a good rate of absorbency, such as facial and bath tissue, are provided by forming a tissue sheet with a non-fibrous polymeric surface structure and thereafter topically applying a softening composition comprising a polysiloxane, a fatty alkyl derivative and glycerin. The non-fibrous polymeric surface structure is created by applying an additive composition to the surface of a tissue sheet prior to or after drying. The additive composition can be an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer.

  • 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.
