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.
