Tissue product comprising bamboo
The disclosure provides tissue webs, and products incorporating the same, where the webs comprise wood and bamboo fibers. More specifically the disclosure provides soft and durable through-air dried tissue webs comprising at least about 10 percent bamboo fiber by weight of the web. In the through-air dried tissue webs of the present disclosure, bamboo typically replaces high average fiber length wood fibers, which increases the bulk of the through-air dried web without negatively effecting softness or durability.
1. A multi-layered, through-air dried, tissue web comprising a first fibrous layer and a second fibrous layer, the first fibrous layer comprising wood fibers and the second fibrous layer comprising bamboo fibers, wherein the first fibrous layer is substantially free of bamboo fibers and wherein the bamboo fibers comprise at least about 10 percent of the total weight of the web, the web having a GMT from about 600 to about 1,000 g/3″, a basis weight from about 20 to about 45 gsm, and a bulk greater than about 10 cc/g.
2. The tissue web of claim 1 wherein the web comprises less than about 5 percent, by weight of the web, softwood fibers.
3. The tissue web of claim 1 wherein the second fibrous layer comprises from about 75 to about 100 percent bamboo fibers.
4. The tissue web of claim 1 wherein the first fibrous layer consists essentially of hardwood pulp fibers and the second fibrous layer comprises from about 80 to about 95 percent bamboo fibers.
5. The tissue web of claim 1 wherein the web has a Tear Index from about 7 to about 20.
6. The tissue web of claim 1 wherein the web has a Stiffness Index less than about 14.
7. The tissue web of claim 1 wherein the web has a Stiffness Index from about 5 to about 14 and a Burst Index greater than about 5.
8. The tissue web of claim 1 wherein the web has a Durability Index greater than about 20.
9. The tissue web of claim 1 wherein the web has a TEA Index greater than about 8.
10. The tissue web of claim 1 wherein the web has a Burst Index greater than about 5.
11. A multi-layered, through-air dried, tissue web comprising a first fibrous layer and a second fibrous layer, the first fibrous layer comprising wood fibers and the second fibrous layer comprising bamboo fibers, wherein the first fibrous layer is substantially free of bamboo fibers and wherein the bamboo fibers comprise at least about 10 percent of the total weight of the web, the web having a GMT from about 1,500 to about 3,000 g/3″, a basis weight from about 35 to about 50 gsm, and a bulk greater than about 10 cc/g.
12. The tissue web of claim 11 wherein the web comprises less than about 5 percent, by weight of the web, softwood fibers.
13. The tissue web of claim 11 wherein the second fibrous layer comprises from about 75 to about 100 percent bamboo fibers.
14. The tissue web of claim 11 wherein the first fibrous layer consists essentially of hardwood pulp fibers and the second fibrous layer comprises from about 80 to about 95 percent bamboo fibers.
15. The tissue web of claim 11 wherein the web has a Tear Index greater than about 10.
16. The tissue web of claim 11 wherein the web has a Stiffness Index less than about 8.
17. The tissue web of claim 11 wherein the web has a Stiffness Index from about 5 to about 8 and a Burst Index greater than about 5.
18. The tissue web of claim 11 wherein the web has a Durability Index greater than about 20.
19. The tissue web of claim 11 wherein the web has a TEA Index greater than about 8.
20. The tissue web of claim 11 wherein the web has a Burst Index greater than about 5.
