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.
