  • Publication number: 20220333314
    Abstract: A method of making a paper product can comprise making one or more sheets at least by, for each of the sheet(s), forming a web from one or more furnishes that comprise fibers dispersed in water. The fibers of the furnish(es) can comprise a plurality of first fibers that are hardwood fibers and a plurality of second fibers that include softwood fibers and surface enhanced pulp fibers (SEPF), the SEPF having a length weighted average fiber length of at least 0.20 mm. The method can comprise at least partially dewatering the web to form the sheet. The sheet(s) can be laminated and/or embossed such that a total dry tensile strength of the paper product is less than or equal to 90% of the sum of the total dry tensile strength(s) of the sheet(s).

  • Publication number: 20220333312
    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.

  • Patent number: 10844546
    Abstract: A process having the steps of producing the web material with the papermaking machine; measuring a molar amount of a monovalent inorganic ionizable cation species (MIICS) in the web material; measuring a molar amount of a divalent inorganic ionizable cation species (DIICS) in the web material; calculating a molar ratio of the measured molar amount of the MIICS to the measured molar amount of the DIICS in the web material; determining if the molar ratio of MIICS to DIICS is about less than or equal to 10; and, if the molar ratio of MIICS to DIICS is greater than about 10, adding an amount of DIICS to the papermaking machine to adjust the molar ratio of MIICS to DIICS so the web material adhering to the Yankee drum drying system has a molar ratio of MIICS to DIICS of about less than or equal to 10, is disclosed.

  • Patent number: 10844547
    Abstract: A process for manufacturing a web material is disclosed. The process generally comprises the steps of providing a papermaking machine with a monovalent inorganic ionizable cation species (MIICS) and a divalent inorganic ionizable cation species (DIICS) measuring devices, measuring molar concentrations of MIICS and DIICS in the web material with the MIICS and DIICS measuring devices and calculating a molar ratio of the measured molar concentration of the MIICS to the measured molar concentration of the DIICS, and subsequently determining if the calculated molar ratio is about less than or equal to 10. If the molar ratio is greater than 10, adding an amount of DIICS to the papermaking machine and manufacturing the web material with the papermaking machine with the added amount of DIICS.
