Abstract

Creped tissue webs having low surface-roughness and high sheet bulk are disclosed. Specifically creped, single ply tissue web having a single wire probe mean deviation of MIU (MMD) of less than about 0.040 and a sheet bulk of greater than about 12 cc/g are disclosed. Additionally creped, multi-ply tissue web having a single wire probe mean deviation of MUI (MMD) of less than about 0.035 and a sheet bulk of greater than about 10 cc/g are disclosed.

First claim

We claim:

1. A rolled tissue product comprising a multi-ply web spirally wound into a roll, the multi-ply web comprising a first creped through-air dried web and second creped through-air dried web, the multi-ply web having a sheet bulk greater than about 12.0 cc/g, a Stiffness Index from about 7.5 to about 10.0 and a single wire probe mean deviation of MUI (MMD) from about 0.020 to about 0.035.

2. The rolled tissue product of claim 1 , wherein the rolled tissue product has a Kershaw roll firmness from about 5.0 to about 10.0 mm.

3. The rolled tissue product of claim 1 , wherein the multi-ply web has a geometric mean tensile (GMT) greater than about 700 g/3″.

4. The rolled tissue product of claim 1 , wherein the multi-ply web has a GMT from about 700 to about 1,000 g/3.

5. The rolled tissue product of claim 1 , wherein the multi-ply web has a basis weight from about 35 to about 40 grams per square meter (gsm).

6. The rolled tissue product of claim 1 , wherein the rolled tissue product has a roll bulk from about 10 to about 12 cc/g.

7. The rolled tissue product of claim 1 , wherein the multi-ply web has a single wire probe mean deviation of Surface Thickness (SMD) of less than about 3.5 microns.

8. The rolled tissue product of claim 1 , wherein the multi-ply web has a MIU value less than about 0.800.

9. The rolled tissue product of claim 1 , wherein the multi-ply web has a single wire probe mean deviation of Surface Thickness (SMD) from about 1.5 to about 3.5 microns and a MIU value from about 0.600 to about 0.800.

10. A rolled tissue product comprising a single ply web spirally wound into a roll, the web comprising a creped through-air dried web having a basis weight less than about 40 gsm, a sheet bulk greater than about 12 cc/g, a Stiffness Index less than about 8.0 and a single wire probe mean deviation of MUI (MMD) from about 0.030 to about 0.040.

11. The rolled tissue product of claim 10 , wherein the single ply web has a basis weight from about 35 to about 38 gsm.

12. The rolled tissue product of claim 10 , wherein the single ply web has a Stiffness Index from about 6.0 to about 8.0.

13. The rolled tissue product of claim 10 , wherein the single ply web has a GMT from 650 to about 1,000 g/3″.

14. The rolled tissue product of claim 10 , wherein the single ply web has a MIU value from about 0.550 to about 0.700.

15. The rolled tissue product of claim 10 , wherein the single ply web has a single wire probe mean deviation of Surface Thickness (SMD) from about 1.5 to about 3.5 microns.
