The disclosure provides a wet-pressed tissue product comprisingfiber 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-yieldfibers from the leaves of, Eucalyptus Hardwood Kraft (EHWK) fibers and Northern bleached softwood kraft (NBSK), wherein the high-yieldfibers 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&#x2033; and sheet bulk greater than about 7.0 cc/g.

High bulk wet-pressed agave tissue

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&#x2033; 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.

Soft tissue comprising non-wood fibers

The present invention provides soft, durable and bulky tissue products comprising non-wood fibers and more particularlyfiber. The inventors have discovered that high yieldpulp 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&#x2033; 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.

The present invention relates to tissue products comprising high yieldfiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yieldpulp 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.

Highly durable towel comprising non-wood fibers

The invention provides tissue products comprisingfibers and methods of producing the same. Preferably thefibers are high yieldpulp 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 percentfiber 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-yieldfibers from the leaves ofHardwood Kraft (EHWK) and Northern Softwood Kraft (NSWK), wherein the high-yieldfibers 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.

High strength and low stiffness agave tissue

The present invention relates to tissue products comprising high yieldfiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yieldpulp 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 8.0 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.
