  • Patent number: 11220785
    Abstract: A tissue machine (1) has a Yankee (3) and a shoe roll (4) that forms a nip with the Yankee (3). The nip has a maximum extension from an entry point (7) to an exit point (8). A flexible belt (9) forms an outer circumference of the roll (4). A fabric (10) carries a fibrous web (W) to the nip and passes through the nip with the web. The fabric (10) reaches the circumference of the roll (4) at a first contact point (11) and wraps the roll (4) from the first contact point to the nip. A mechanical support (12) inside the belt (9) supports the belt (9) between the first contact point (11) and the nip. The fabric (10) wraps the roll (4) from the first contact point (11) by more than 80°. The invention also relates to a method of operating the machine.

  • Patent number: 11162223
    Abstract: The invention relates to fibrous structures having desirable physical properties, such as good tensile strength, low stiffness and high bulk, manufactured using a fiber furnish comprising cellulosic fibers having a pH of 5.0 or less and at least one strength resin. Not only do structures prepared with acidic fibers have desirable physical properties, they may also be manufactured in an energy efficient manner. To achieve the greatest energy savings it is generally desirable that acidic fibers not be subjected to mechanical treatment, such as by refining, prior to forming the fiber into a fibrous structure. Further, it may be desirable to subject the remainder of the fiber furnish to a minimal degree of mechanical treatment, such as by refining, so as to produce a furnish having a freeness greater than about 550 mL.

  • Patent number: 9506201
    Abstract: The invention provides methods and compositions for softening paper. An inventive composition and method of its use softens paper products (like tissue paper) by de-bonding its cellulose fibers and by improving the smoothness of the resulting paper. The invention forms a surfactant-polymer complex that attaches de-bonding non-ionic surfactants to cellulose fibers that would otherwise not be retained by the cellulose fibers. This complex prevents the fibers from bonding with each other and makes the paper product smoother. Best of all, the composition is environmentally superior and is a non-toxic.

  • Patent number: 9464386
    Abstract: A method is provided for preventing, minimizing, and/or eliminating the migration of mineral oils from paper food packaging into packaged food. The method can include adding a copper-containing oxidase enzyme, such as a laccase enzyme, to a paper pulp from which the paper food packaging is to be formed. The migration of mineral oils originating from residual inks in recycled old corrugated containers and old newsprint, is particularly suppressed, including the migration of C10-C25 fractions of aromatic mineral oil hydrocarbons and of saturated mineral oil hydrocarbons.

  • Patent number: 9410292
    Abstract: The disclosure provides a multilayered tissue web comprising treated cellulosic fibers selectively disposed in one or more layers, wherein the tissue layer comprising treated fibers is adjacent to a layer comprising untreated fiber and which is substantially free from untreated fiber. Generally the treated fibers have a rate of substitution of about 0.02 to 0.07. In this manner, the disclosure provides a multi-layered tissue web having treated fiber selectively incorporated therein, where the tissue web has basis weight greater than about 10 grams per square meter (gsm), such as from about 10 to about 50 gsm, a sheet bulk greater than about 8 cc/g, such as from about 8 to about 15 cc/g and Stiffness Index less than about 15, such as from about 8 to about 12.

  • Patent number: 9382665
    Abstract: A method of making a wiper/towel product includes compactively dewatering a nascent web having cellulosic microfibers and an apparently random distribution of fibers. The dewatered web is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a creping belt. The belt-creping step occurs under pressure in a belt creping nip. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the hollow domed regions.

  • Patent number: 9365982
    Abstract: It has now been discovered that the ratio of the wet tensile strength to the dry tensile strength of a tissue web, and more particularly a creped tissue web, can meet or exceed satisfactory levels without the excess use of a wet strength resin. For example, by treating the tissue making furnish with less than about 3 kilograms of wet strength resin per ton of furnish, forming the tissue web, and then creping the tissue web with a creping composition comprising a non-fibrous olefin polymer and a dispersing agent, a tissue web having a CD Wet/Dry ratio greater than about 0.30 may be produced. This discovery provides the flexibility to produce a tissue product with increased wet strength while reducing the add-on of wet strength agent.
