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.

Claims (13)

1. A rolled tissue product comprising a first through-air dried tissue ply and a second through-air dried tissue ply joined in facing arrangement to one another by a plurality of embossments and spirally wound about a core, the product having a basis weight from 35 to 60 grams per square meter, a geometric mean tensile strength (GMT) from 700 to 1,400 g/3″, a sheet bulk from 12.0 to 20.0 cc/g and a Roll Structure from 1.0 to 2.0.

2. The rolled tissue product of claim 1 wherein the multi-ply tissue product has a geometric mean stretch from about 11.0 to about 15.0%.

3. The rolled tissue product of claim 1 having a Roll Structure from 1.2 to about 1.8.

4. The rolled tissue product of claim 1 having a roll bulk from 14.0 cc/g to 18.0 cc/g.

5. The rolled tissue product of claim 1 having a Roll Firmness less than 10.0 mm.

6. The rolled tissue product of claim 1 having a Roll Firmness less than 10.0 mm, a roll bulk from 14.0 cc/g to 18.0 cc/g and a Roll Structure from 1.2 to about 1.8.

7. The rolled tissue product of claim 1 having a GMT from 900 to 1,200 g/3″.

8. The rolled tissue product of claim 1 having a geometric mean slope (GM Slope) mean slope less than about 9,000 g/3″.

9. The rolled tissue product of claim 1 having a GM Slope from 4,000 to 8,000 g/3″.

10. The rolled tissue product of claim 1 wherein the first through-air dried tissue ply or the second through-air dried tissue ply have an outer surface having a plurality of elements disposed thereon in a pattern and providing the outer surface with a three dimensional surface topography.

11. The rolled tissue product of claim 10 wherein the plurality of elements are wave-like linear elements having an amplitude (A) and a wavelength (L).

12. The rolled tissue product of claim 11 wherein the amplitude ranges from about 10 to about 40 mm and the wavelength ranges from about 20 to about 500 mm.

13. The rolled tissue product of claim 11 wherein each of the plurality of linear elements are equally spaced apart from one another in the cross-machine direction and the spacing between adjacent elements ranges from 2.0 to about 10 mm.
