HIGH STRENGTH AND LOW STIFFNESS HESPERALOE TISSUE

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.

LAYERED FIBROUS STRUCTURES COMPRISING CROSS-LINKED FIBERS

The invention provides fibrous structures, such as tissue products, manufactured using non-compressive dewatering and drying methods, such as through-air drying, where the structures are multi-layered and have cross-linked fibers selectively disposed in one or more outer most layers. Compared to similarly prepared fibrous structures that are substantially free from cross-linked fibers the instant fibrous structures have improved surface properties, such as good softness and smoothness, as well as improved bulk. Further, by layering the cross-linked fibers and manufacturing the fibrous structures without compressive dewatering the tensile strength of the finished structure is not degraded.
