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.

MULTI-LAYERED PRODUCT HAVING AN EMBOSSED INTERIOR LAYER AND A METHOD FOR MAKING THE PRODUCT
20230226795 · 2023-07-20 ·

A multi-layered product having an embossed interior layer is disclosed along with a method of making the product. The multi-layered product has a first layer with an interior surface, a second layer with an interior surface, and a third layer sandwiched between the first and second layers. The third layer has a first surface and a second surface and has a thickness therebetween. The third layer is embossed into a waffle pattern having a plurality of protrusions and a plurality of recesses. Each of the plurality of protrusions and recesses is adjacently aligned and horizontally offset from one another. The plurality of protrusions forms a horizontal plane, at the first surface, which is positioned above a horizontal plane formed by the plurality of recesses, at the first surface. The product also has an adhesive which secures the three layers together.
