  • Publication number: 20230407574
    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.

  • Patent number: 11634870
    Abstract: The present invention provides multi-layered tissue webs, and tissue products comprising the same, the multi-layered webs comprising wood fibers and non-wood cellulosic fibers where the non-wood cellulosic fibers are selectively deposited in one or more outer layers of the multi-layered web. Surprisingly disposing non-wood cellulosic fibers in the outer layers, even in relatively modest amounts, alters the machine and/or cross-machine direction properties of the resulting web, such that MD:CD tensile ratio may be reduced.

  • Patent number: 11261568
    Abstract: The disclosure provides a wet-pressed tissue product comprising Agave fiber and having improved sheet bulk and good cross-machine tensile, toughness and durability properties. Cross-machine properties are significant because tissue products often fail in the cross-machine direction because it is often the weaker of the two product orientations (cross and machine directions). Accordingly, in certain embodiments the present disclosure provides a three-layered single-ply wet-pressed tissue product comprising high-yield Agave fibers from the leaves of Agave tequilana, Eucalyptus Hardwood Kraft (EHWK) fibers and Northern bleached softwood kraft (NBSK), wherein the high-yield Agave fibers comprise at least about 5.0 percent by weight of the tissue product, the product having a CD tensile greater than about 450 g/3? and sheet bulk greater than about 7.0 cc/g.

  • Publication number: 20200040529
    Abstract: The disclosure provides fibrous structures and tissue products comprising a volatile agave compound selected from the group consisting of limonene, hexanaldehyde and 6-Methyl-5-hepten-2-one. The volatile agave compounds may be provided by forming the structures at least in-part from agave fiber, such as Agave tequilana fiber. In other embodiments the volatile agave compounds may be incorporated in the fibrous structures by adding the compounds during formation of the fibrous structure, such as by adding the compounds to the furnish, or by topically applying the compounds to the fibrous structure after formation, in order to provide a lemon-like scent to the fibrous structure.

  • Patent number: 10428465
    Abstract: The invention provides tissue products comprising agave fibers and methods of producing the same. Preferably the agave fibers are high yield agave pulp fibers, which have demonstrated the ability to replace a substantial portion of the long fiber fraction of the furnish without negatively effecting important tissue product properties such as stiffness, CD Durability and bulk. Thus, the tissue product may comprise greater than about 10 weight percent agave fiber and more preferably greater than about 25 weight percent. Accordingly, in certain embodiments the present disclosure provides a three-layered through-air dried tissue product comprising high-yield agave fibers from the leaves of Agave tequilana, Eucalyptus Hardwood Kraft (EHWK) and Northern Softwood Kraft (NSWK), wherein the high-yield agave fibers comprise 10.0 percent by weight of the tissue product, the product having a CD durability greater than about 18 and sheet bulk greater than about 10 cc/g.

  • Patent number: 10337147
    Abstract: The invention provides tissue products comprising hesperaloe fibers and having satisfactory strength in-use and good dispersibility. To produce the instant tissue products the inventors have successfully moderated the changes in strength and stiffness typically associated with substituting conventional wood papermaking fibers, such as NSWK, with hesperaloe fibers. Not only have the inventors succeeded in moderating changes to strength and stiffness they have improved dispersibility. As such, the tissue products of the present invention have properties comparable to, or better than, those produced using conventional papermaking fibers, such as wood pulp fibers.
