Estimating the term…
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.
A tissue product comprising at least about 20 weight percent high yield hesperaloe pulp fibers, the tissue product having a GMT from about 400 to about 1,000 g/3″ and a Stiffness Index less than about 10.0.
A tissue product comprising at least one multi-layered through-air dried tissue web comprising a first and a second layer, the first layer being substantially free from high yield hesperaloe pulp fibers and the second layer consisting essentially of high yield hesperaloe pulp fibers, the tissue product having a Durability Index greater than about 28.0 and a Stiffness Index less than about 10.0, wherein the tissue product comprises from about 20 to about 50 weight percent high yield hesperaloe pulp fibers.
A single-ply through-air dried tissue product comprising at least about 20 weight percent high yield hesperaloe pulp fibers, the tissue product having a basis weight from about 30 to about 60 gsm, a sheet bulk greater than about 10 cc/g and a Stiffness Index less than about 10.
