Abstract

Spirally wound paper products are disclosed having desirable roll bulk, firmness and softness properties. The rolled products can be made from a multiple ply tissue webs formed according to various processes. Tissue webs having basis weights greater than about 40 grams per square meter were wound into rolls having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 15 cc/g. Similarly, tissue webs having basis weights less than about 40 grams per square meter were wound into rolls having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 18 cc/g.

Claims (41)

1. A rolled tissue product comprising a multi-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 15 cc/g, the tissue web having a basis weight of greater than about 40 gsm.

2. The tissue product of claim 1 , wherein at least one ply of the multi-ply tissue web comprises a through-air dried web.

3. The tissue product of claim 1 , wherein the roll bulk is about 17 cc/g or greater.

4. The tissue product of claim 1 , wherein the roll bulk is about 18 cc/g or greater.

5. The tissue product of claim 1 , wherein the Kershaw firmness is less than about 8 mm.

6. The tissue product of claim 1 , wherein the Kershaw firmness is from about 5 mm to about 8 mm.

7. The tissue product of claim 1 , wherein the geometric mean tensile strength of the tissue web is about 900 g/3 inches or greater.

8. The tissue product of claim 1 wherein the geometric mean tensile strength of the tissue web is from about 900 g/3 inches to about 1300 g/3 inches.

9. The tissue product of claim 1 wherein the CD stretch of the tissue web is greater than about 10 percent.

10. The tissue product of claim 1 wherein the CD stretch of the tissue web is from about 10 to about 15 percent.

11. The tissue product of claim 1 wherein the Burst Strength of the tissue web is greater than about 1000 grams.

12. The tissue product of claim 1 , wherein the multi-ply tissue web comprises two plies.

13. The tissue product of claim 12 , wherein the two plies comprise through-air dried webs.

14. A rolled tissue product comprising a through-air dried multi-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 15 cc/g, the tissue web having a basis weight of greater than about 40 gsm, a Burst Strength greater than about 1000 grams and a geometric mean tensile strength from about 900 to about 1300 g/3 inches.

15. A rolled tissue product comprising a multi-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 18 cc/g, the tissue web having a basis weight less than about 40 gsm.

16. The tissue product of claim 15 , wherein at least one ply of the multi-ply tissue web comprises an uncreped through-air dried web.

17. The tissue product of claim 15 , wherein the roll bulk is from about 18 to about 22 cc/g.

18. The tissue product of claim 15 , wherein the Kershaw firmness is from about 5 to about 9 mm.

19. The tissue product of claim 15 , wherein the basis weight of the tissue web is from about 32 to about 38 gsm.

20. The tissue product of claim 15 , wherein the geometric mean tensile strength of the tissue web is about 900 g/3 inches or greater.

21. The tissue product of claim 15 , wherein the geometric mean tensile strength of the tissue web is from about 900 to about 1300 g/3 inches.

22. The tissue product of claim 15 , wherein the CD stretch of the tissue web is greater than about 7 percent.

23. The tissue product of claim 15 , wherein the CD stretch of the tissue web is greater than about 10 percent.

24. The tissue product of claim 15 , wherein the CD stretch of the tissue web is from about 13 to about 15 percent.

25. The tissue product of claim 15 , wherein the Absorbency is greater than about 16 grams per gram.

26. The tissue product of claim 15 , wherein the tissue web comprises two plies.

27. The tissue product of claim 26 , wherein the two plies comprise uncreped through-air dried webs.

28. A rolled tissue product comprising a multi-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 10 mm and a roll bulk of greater than about 18 cc/g, the multi-ply tissue web having a first and a second surface, the first surface having a Surface Smoothness from about 0.15 to about 0.25 MIU, wherein the web has a basis weight less than about 50 gsm.

29. The tissue product of claim 28 , wherein at least one ply of the multi-ply tissue web comprises an uncreped through-air dried web.

30. The tissue product of claim 28 , wherein the multi-ply tissue web comprises two plies.

31. The tissue product of claim 28 , wherein the Kershaw firmness is from about 3 to about 5 mm.

32. The tissue product of claim 28 , wherein the geometric mean tensile strength of the tissue web is from about 900 to about 1300 g/3 inches.

33. The tissue product of claim 29 wherein the CD stretch of the tissue web is from about 7 to about 12 percent.

34. A rolled tissue product comprising a multi-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 5 mm and a roll bulk of greater than about 10 cc/g, the multi-ply tissue web having a first and a second surface, the first surface having a Surface Smoothness greater than about 0.15 MIU, wherein the web has a basis weight greater than about 40 gsm.
