Soft tissue comprising non-wood fibers
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.
1. A tissue product comprising wood pulp fibers and from about 5 to about 50 weight percent high yield hesperaloe pulp fibers, the product having a geometric mean tensile (GMT) less than about 1000 g/3″ and a geometric mean slope (GM Slope) less than about 7.0 kg.
2. The tissue product of claim 1 having a GMT from about 400 to less than about 1,000 g/3″.
3. The tissue product of claim 1 having a GMT from about 500 to about 800 g/3″.
4. The tissue product of claim 1 having a GM Slope from about 4.5 to about 7.0 kg.
5. The tissue product of claim 1 having a GMT from about 400 to less than about 1,000 g/3″ and a GM Slope from about 4.5 to about 7.0 kg.
6. The tissue product of claim 1 having a Stiffness Index from about 7.0 to about 9.0.
7. The tissue product of claim 1 having a Durability Index from about 25 to about 35.
8. The tissue product of claim 1 having a GMT from about 400 to less than about 1,000 g/3″, a Durability Index from about 30 to about 35 and a Stiffness Index from about 8.0 to about 10.0.
9. The tissue product of claim 8 having a GM Slope from about 4.5 to about 7.0 kg.
10. The tissue product of claim 1 comprising less than about 5 weight percent Northern softwood kraft (NSWK) and from about 10 to about 40 weight percent high yield hesperaloe fiber.
11. The tissue product of claim 1 comprising at least one multi-layered through-air dried web wherein the high yield hesperaloe fiber is selectively disposed in only one layer of the multi-layered through-air dried web.
12. The tissue product of claim 1 having a Burst Index greater than about 8.0.
13. The tissue product of claim 1 having a TEA Index greater than about 9.0.
14. The tissue product of claim 1 having a Tear Index greater than about 12.0.
15. The tissue product of claim 1 having a basis weight from about 30 to about 60 grams per square meter (gsm).
