  • Patent number: 10450703
    Abstract: The present application provides a tissue product comprising at least about 10 weight percent high coarseness fibers, from about 1.0 to about 10 weight percent synthetic fibers and less than about 10 weight percent long, low-coarseness cellulosic fibers. The high coarseness fibers may be cellulosic fibers having an average fiber length greater than about 2.0 mm and a coarseness greater than 17 mg/100 m, such as Southern softwood kraft pulp fibers (SSWK) derived from a pine in the Pinus subgenus, and the synthetic fiber is a non-cellulosic, thermoplastic fiber such as non-fibrillated polyethylene terephthalate (PET) fibers. In certain embodiments the tissue products may be substantially free from long, low coarseness cellulosic fibers, yet provide satisfactory strength, such as a geometric mean tensile from about 500 to about 1,200 g/3?, and softness, such as a TS7 less than about 11.0.

  • 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.

  • Publication number: 20190264395
    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.

  • Publication number: 20190249367
    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: 20190161916
    Abstract: The present invention provides a tissue product formed from a fiber furnish consisting essentially of short cellulosic fibers, such as fibers having an average fiber length less than about 2.0 mm, and a synthetic fiber having at least one cross-section dimension less than about 20 microns. The invention also provides a tissue product comprising at least one wet laid multi-layered tissue web comprising a fiber furnish consisting essentially of synthetic fibers and short cellulosic fibers, the multi-layered tissue web having a first and second outer layer and a middle layer disposed there between where the synthetic fibers are selectively disposed in the middle layer. Generally the tissue product comprises less than about 30 percent, by weight of the tissue product, synthetic fiber. In a preferred embodiment the tissue product comprises non-fibrillated polyethylene terephthalate (PET) fibers having a circular cross-section shape with a diameter less than about 5.

  • Publication number: 20190100878
    Abstract: The present invention relates to tissue products comprising high yield hesperaloe fiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yield hesperaloe pulp fibers surprisingly improves the CD Wet/Dry ratio without negatively affecting the absorbency of the tissue product. For example, tissue products of the present invention generally have an Absorbent Capacity greater than about 6.0 g/g, such as from about 6.0 to 8.0 g/g. As such the tissue products are durable when wet, but are still sufficiently absorbent. This balance of absorbency and wet strength is not found in the prior art without resorting to adding latex binders or the like to the tissue product.

  • Publication number: 20190100883
    Abstract: The present invention provides soft, durable and bulky tissue products comprising non-wood fibers and more particularly hesperaloe fiber. The inventors have discovered that high yield hesperaloe pulp fiber, when incorporated in amounts of at least about 5 percent by weight of the tissue product, produces products having a GMT less than about 1000 g/3? and a GM Slope less than about 7.0 kg. At the foregoing tensile strengths and modulus the tissue products of the present invention are also generally soft, such as having a Stiffness Index less than about 10.0, and more preferably less than about 9.0, such as from about 7.0 to about 9.0.

  • Patent number: 9890502
    Abstract: The present invention generally relates to tissue webs and products, which generally have a basis weight less than about 80 grams per square meter (gsm) and a sheet bulk greater than about 5 cubic centimeters per gram (cc/g) comprising a blend of conventional papermaking fibers and high carbohydrate fillers. Surprisingly, the fillers may displace a relatively large amount of conventional papermaking fibers, such as hardwood kraft pulp, without negatively affecting important tissue properties such as caliper, bulk, slough, absorbent capacity and softness. In fact, in certain instances the use of fillers actually improves tissue properties.
