Abstract

Spirally wound paper products are disclosed having desirable roll firmness characteristics and softness properties. The rolled products can be made from a single ply tissue web formed according to various processes. Once formed, the tissue web is subjected to a shear-calendering device that increases the fuzz-on-edge properties of the web and preserves the bulk of the web when wound.

Claims (37)

1. A rolled tissue product comprising:

a single-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 7.8 mm and a roll bulk of greater than about 10 cc/g, the tissue web having a basis weight of greater than about 30 gsm bone dry, the tissue web further having a fuzz-on-edge of greater than about 1.7 mm/mm on at least one side of the web and a geometric mean tensile strength of greater than about 550 g/3 inches.

2. A tissue product as defined in claim 1 , wherein the base web comprises an uncreped through-air dried web.

3. A tissue product as defined in claim 1 , wherein the roll bulk is about 10.5 cc/g or greater.

4. A tissue product as defined in claim 1 , wherein the roll bulk is about 11 cc/g or greater.

5. A tissue product as defined in claim 1 , wherein the roll bulk is about 11.5 cc/g or greater.

6. A tissue product as defined in claim 1 , wherein the roll bulk is about 12 cc/g or greater.

7. A tissue product as defined in claim 1 , wherein the roll bulk is about 13 cc/g or greater.

8. A tissue product as defined in claim 1 , wherein the roll bulk is about 14 cc/g or greater.

9. A tissue product as defined in claim 1 , wherein the Kershaw firmness is less than about 7.6 mm.

10. A tissue product as defined in claim 1 , wherein the Kershaw firmness is less than about 7.3 mm.

11. A tissue product as defined in claim 1 , wherein the Kershaw firmness is from about 7.0 to about 7.8 mm.

12. A tissue product as defined in claim 1 , wherein the Kershaw firmness is from about 7.2 to about 7.5 mm.

13. A tissue product as defined in claim 1 , wherein the basis weight of the tissue web is about 32 gsm bone dry or greater.

14. A tissue product as defined in claim 1 , wherein the basis weight of the tissue web is about 34 gsm bone dry or greater.

15. A tissue product as defined in claim 1 , wherein the basis weight of the tissue web is about 36 gsm bone dry or greater.

16. A tissue product as defined in claim 1 , wherein the basis weight of the tissue web is from about 30 gsm to about 38 gsm bone dry.

17. A tissue product as defined in claim 1 , wherein the basis weight of the tissue web is from about 32 gsm to about 36 gsm bone dry.

18. A tissue product as defined in claim 1 , wherein the geometric mean tensile strength of the tissue web is about 550 g/3 inches or greater.

19. A tissue product as defined in claim 1 , wherein the geometric mean tensile strength of the tissue web is about 600 g/3 inches or greater.

20. A tissue product as defined in claim 1 , wherein the geometric mean tensile strength of the tissue web is about 650 g/3 inches or greater.

21. A tissue product as defined in claim 1 , wherein the fuzz-on-edge of at least one side of the tissue web is about 2.0 mm/mm or greater.

22. A tissue product as defined in claim 1 , wherein the fuzz-on-edge of at least one side of the tissue web is about 2.5 mm/mm or greater.

23. A tissue product as defined in claim 1 , wherein the fuzz-on-edge of at least one side of the tissue web is about 3.0 mm/mm or greater.

24. A tissue product as defined in claim 1 , wherein the fuzz-on-edge of at least one side of the tissue web is about 3.5 mm/mm or greater.

25. A tissue product as defined in claim 1 , wherein the machine direction coefficient of friction of the higher fuzz-on-edge side of the tissue web is greater than about 0.32.

26. A tissue product as defined in claim 1 , wherein the cross-machine direction coefficient of friction of higher fuzz-on-edge side of the tissue web is greater than about 0.32.

27. A tissue product as defined in claim 1 , wherein the tissue web has a bending stiffness/GM slope A that is less than about 0.006.

28. A tissue product as defined in claim 1 , wherein the tissue web has a compression linearity of less than about 0.50.

29. A rolled tissue product comprising:

a single-ply tissue web spirally wound into a roll, the wound roll having a Kershaw roll firmness of less than about 78 mm and a roll bulk of greater than about 13 cc/g, the tissue web having a basis weight of greater than about 30 gsm bone dry, the tissue web having a fuzz-on-edge of greater than about 1.3 mm/mm on at least one side of the web and a geometric mean tensile strength of greater than about, 550 g/3 inches.

30. A rolled tissue product as defined in claim 29 , wherein the wound roll has a roll bulk of greater than about 14 cc/g.

31. A rolled tissue product as defined in claim 29 , wherein the tissue web has a fuzz-on-edge of greater than about 2 mm/mm on at least one side of the web.

32. A rolled tissue product as defined in claim 29 , wherein the tissue web has a fuzz-on-edge of greater than about 3 mm/mm on at least one side of the web.

33. A rolled tissue product as defined in claim 29 , wherein the tissue web has a basis weight of from about 30 gsm to about 38 gsm.

34. A rolled tissue product as defined in claim 29 , wherein the wound roll has a Kershaw roll firmness of from about 7.0 to about 7.8.

35. A rolled tissue product as defined in claim 29 , wherein the wound roll has a Kershaw roll firmness of from about 7.2 to about 7.5.
