Abstract

The present disclosure provides high bulk tissue products, as well as an apparatus and methods for manufacturing the same. The tissue products provided herein not only have high bulk, but they also have improved surface smoothness, particularly compared to tissue products of similar basis weights.

First claim

We claim:

1. A rolled tissue product comprising a multi-ply tissue product spirally wound into a roll, the multi-ply tissue product having a caliper greater than 600 μm and a Surface Smoothness S90 value less than 95 μm, wherein the rolled tissue product has a Roll Structure from about 1.2 to about 1.8.

2. The rolled tissue product of claim 1 wherein the multi-ply tissue product has a Stiffness Index from about 4 to about 8.

3. The rolled tissue product claim 1 wherein the multi-ply tissue product has a geometric mean slope less than about 10,000 grams per 76.2 mm sample width.

4. The rolled tissue product of claim 1 wherein the multi-ply tissue product has a geometric mean stretch greater than about 10 percent.

5. The multi ply tissue rolled tissue product claim 1 wherein the multi-ply tissue product has a basis weight from about 35 to about 45 gsm and a GMT from about 700 to about 1400 grams per 76.2 mm sample width.

6. The rolled tissue product of claim 1 wherein the multi-ply tissue product has a Surface Smoothness Sa value less than about 25 μm and a Surface Smoothness Sq value less than about 40 μm.

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

8. The rolled tissue product of claim 1 wherein at least one ply of the multi-ply tissue product comprises an uncreped through-air dried web.

9. The rolled tissue product of claim 1 wherein the multi-ply tissue product comprises two plies and has a basis weight greater than about 35 gsm, a sheet bulk greater than about 15 cc/g and a Stiffness Index less than about 7.

10. The rolled tissue product of claim 1 wherein the multi-ply tissue product comprises two plies and has a basis weight greater than about 35 gsm, a sheet bulk greater than about 15 cc/g and wherein the rolled tissue product has a Roll Firmness less than about 10 mm.

11. The rolled tissue product of claim 10 wherein the rolled tissue product has a Roll Firmness from about 8 to about 10 mm.

12. The rolled tissue product of claim 1 wherein the multi-ply tissue product comprises two plies and has a caliper from 600 to about 1000 μm and a Surface Smoothness S90 from about 70 to 95 μm.

13. The rolled tissue product of claim 1 wherein the multi-ply tissue product comprises two plies and wherein the rolled tissue product has a Roll Structure from 1.0 to about 2.0.

14. The rolled tissue product of claim 1 wherein each ply of the multi-ply tissue product comprises a through-air dried web having a three-dimensional wave-like surface topography.

15. The rolled tissue product of claim 14 wherein the three-dimensional wave-like surface topography has an amplitude ranging from about 10 to about 40 mm and a wavelength ranging from about 80 to about 120 mm.

16. A rolled tissue product comprising two tissue plies spirally wound into a roll, the two tissue plies having a basis weight greater than about 35 grams per square meter (gsm), a caliper greater than 600 μm, a sheet bulk greater than about 15 cc/g, a Stiffness Index less than about 7, and a Surface Smoothness S90 value less than 95 μm.

17. The rolled tissue product of claim 16 having a geometric mean slope less than about 10,000 grams per 76.2 mm sample width.

18. The rolled tissue product of claim 16 having a geometric mean stretch greater than about 10 percent.

19. The multi-ply tissue product of claim 16 having a basis weight from about 35 to about 45 gsm and a GMT from about 700 to about 1400 grams per 76.2 mm sample width.
