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.

High strength and low stiffness hesperaloe tissue

Hesperaloe tissue having improved cross-machine direction properties

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.
