Tissue product comprising bamboo
View Patent ↗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 through-air dried tissue web comprising bamboo fibers having a basis weight from about 10 to about 60 grams per centimeter squared and a Bulk greater than about 5 cubic centimeters per gram wherein the bamboo fibers comprise from about 10 to about 75 percent by weight of the through-air dried tissue web.
2. The through-air dried tissue web of claim 1 wherein the bamboo fibers have an average fiber length from about 1 to about 2 mm.
3. The through-air dried tissue web of claim 1 wherein the bamboo fiber is derived from a bamboo species selected from the group consisting of Phyllostachys heterocycla pubescens, Phyllostachys nigra variant Heno, Phyllostachys vivax and Phyllostachys bambusoides.
4. The through-air dried tissue web of claim 1 wherein the through-air dried web comprises less than about 10 percent softwood fibers by weight of the through-air dried web.
5. The through-air dried tissue web of claim 1 having a Durability Index greater than about 20.
6. The through-air dried tissue web of claim 1 having a Stiffness Index less than about 10.
7. The through-air dried tissue web of claim 1 having a Bulk greater than about 10 cubic centimeters per gram.
8. The through-air dried tissue web of claim 1 wherein the through-air dried web is uncreped.
9. A tissue product comprising a first through-air dried tissue web having from about 10 percent to about 75 percent bamboo fibers by weight of the through-air dried tissue web, the tissue product having a basis weight from about 10 to about 60 grams per square meter and a Bulk greater than about 5 cubic centimeters per gram.
10. The tissue product of claim 9 further comprising a second tissue web plied to the first through-air dried tissue web.
11. The tissue product of claim 9 having a Durability Index greater than about 20.
12. The tissue product of claim 9 having a Stiffness Index less than about 13.
13. The tissue product of claim 9 having a Bulk greater than about 10 cubic centimeters per gram.
14. The tissue product of claim 9 wherein the bamboo fibers comprise from about 20 to about 50 percent of the total weight of the first through-air dried web and the first through-air dried web comprises less than about 10 percent softwood fibers by weight of the through-air dried web.
15. The tissue product of claim 9 having a basis weight from about 20 to about 45 grams per square meter and a Bulk from about 10 to about 22 cubic centimeters per gram.
16. The tissue product of claim 9 having a Stiffness Index from about 5 to about 10.
17. The tissue product of claim 9 wherein the first through-air dried web is uncreped.
18. A tissue product comprising a first through-air dried tissue web comprising from about 10 percent to about 75 percent bamboo fibers by weight of the through-air dried tissue web and substantially free from softwood fiber, the tissue product having a basis weight greater than about 10 grams per square meter, a Stiffness Index less than about 10 and a Durability Index greater than about 20.
19. The tissue product of claim 18 having a Bulk greater than about 10 centimeters per gram.
20. The tissue product of claim 18 further comprising a second through-air dried tissue web plied to the first through-air dried tissue web.
