Abstract

The present disclosure relates to creped tissue webs that demonstrate low surface-roughness and high sheet bulk. The present disclosure relates to a 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. The present disclosure also relates to a 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.

First claim

1 . A rolled tissue product comprising a single ply creped tissue web spirally wound into a roll, the tissue web having a single wire probe mean deviation of MIU (MMD) of less than about 0.040, a roll bulk greater than about 10 cc/g and a sheet bulk of greater than about 12 cc/g.

2 . The tissue product of claim 1 , wherein the single ply creped tissue web is through-air dried.

3 . The tissue product of claim 1 , wherein the rolled tissue product has a Kershaw roll firmness less than about 7.0 mm.

4 . The tissue product of claim 1 , wherein the single ply creped tissue web has a geometric mean tensile (GMT) from about 650 to about 1,000 g/3″.

5 . The tissue product of claim 4 , wherein the single ply creped tissue web has a Stiffness Index of less than about 8.0.

6 . The tissue product of claim 1 , wherein the single ply creped tissue web has a single wire probe mean deviation of surface thickness (SMD) of less than about 3 microns.

7 . A rolled tissue product comprising a multi-ply creped tissue web spirally wound into a roll, the tissue web having a single wire probe mean deviation of MUI (MMD) of less than about 0.035, a roll bulk greater than about 10 cc/g and a sheet bulk of greater than about 10 cc/g.

8 . The tissue product of claim 7 , wherein at least one ply of the multi-ply creped tissue web is through-air dried.

9 . The tissue product of claim 7 , wherein the multi-ply creped tissue web comprises two plies.

10 . The tissue product of claim 7 , wherein the rolled tissue product has a Kershaw roll firmness from about 5.0 to about 10.0 mm.

11 . The tissue product of claim 7 , wherein the multi-ply creped tissue web has a geometric mean tensile (GMT) from about 700 to about 1,000 g/3″.

12 . The tissue product of claim 11 , wherein the multi-ply creped tissue web has a Stiffness Index of less than about 10.0.

13 . The tissue product of claim 7 , wherein the multi-ply creped tissue web has a single wire probe mean deviation of surface thickness (SMD) of less than about 3.5 microns.

14 . The tissue product of claim 7 , wherein the multi-ply creped tissue web has a single wire probe mean deviation of MUI (MMD) from about 0.020 to about 0.035, a roll bulk from about 10 to about 12 cc/g and a sheet bulk from about 10 to about 12 cc/g.

15 . A rolled tissue product comprising a two-ply tissue web spirally wound into a roll, the tissue web comprising a first creped tissue ply and a second creped tissue ply, the tissue web having a single wire probe mean deviation of MUI (MMD) of less than about 0.035, a single wire probe mean deviation of Surface Thickness (SMD) of less than about 3.5 microns, wherein the rolled tissue product has a roll bulk from about 8 to about 12 cc/g and a Kershaw roll firmness from about 3.5 to about 5.0 mm.

16 . The tissue product of claim 15 , wherein the tissue web has a sheet bulk of greater than about 10 cc/g.

17 . The tissue product of claim 15 , wherein the tissue web has a geometric mean tensile (GMT) of greater than about 700 g/3″.

18 . The tissue product of claim 17 , wherein the tissue web has a Stiffness Index of less than about 10.0.

19 . The tissue product of claim 15 wherein the tissue web is through-air dried.

20 . The tissue product of claim 19 wherein the tissue web has a basis weight from about 35 to about 40 gsm.
