Abstract

The present invention provides tissue webs and products having improved z-directional properties. The improved z-directional properties may be achieved by providing the structure with a unique three-dimensional surface topography, which increases the structure's Exponential Compression Modulus (K) and Caliper Under Load (C0). By improving both K and C0, the present inventors have also been able to provide tissue structures with relatively high Compression Energy (E), which enables the structures to be calendered at high loads without significant loss of sheet bulk or degradation of strength.

First claim

We claim:

1. A multi-ply tissue product comprising a calendered and spirally wound multi-ply tissue web having a machine and a cross-machine direction and a first side with a topographical pattern comprising a plurality of substantially machine direction oriented line elements disposed thereon, the product having a Compression Energy (E) from about 0.0130 to about 0.0150 J/mm 2 , a geometric mean tensile (GMT) from about 500 to about 1,500 g/3″ and a sheet bulk greater than about 10.0 cc/g.

2. The tissue product of claim 1 wound into a roll, the wound roll having a Firmness less than about 7.0 mm.

3. The tissue product of claim 1 having a basis weight from about 30 to about 60 gsm and a caliper from about 550 to about 650 μm.

4. The tissue product of claim 1 having a TS7 less than about 10.5 and a TS750 less than about 85.0.

5. The tissue product of claim 1 having a Stiffness Index less than about 7.5.

6. The tissue product of claim 1 having a sheet bulk from about 10.0 to about 14.0 cc/g, a TS7 from about 9.0 to about 10.0 and a TS750 from about 60 to about 75.

7. The tissue product of claim 1 having an Exponential Compression Modulus (K) greater than about 5.0.

8. The tissue product of claim 1 having a Caliper Under Load (C 0 ) greater than about 9.5 mm.

9. A multi-ply tissue product comprising a calendered, non-compressively dewatered and spirally wound multi-ply tissue web, the tissue product having a caliper greater than about 500 μm, a Stiffness Index less than about 7.5 and a Compression Energy (E) greater than about 0.0130 J/mm 2 .

10. The tissue product of claim 9 having a sheet bulk greater than about 10.0 cc/g.

11. The tissue product of claim 9 having a basis weight from about 30 to about 60 gsm and a GMT from about 800 to about 1,500 g/3″.

12. The tissue product of claim 9 having a TS7 less than about 10.5 and a TS750 less than about 85.0.

13. The tissue product of claim 9 having a Caliper Under Load (C 0 ) from about 9.5 to about 10.5 mm.

14. The tissue product of claim 9 having a Compression Energy (E) from 0.0130 to about 0.0150 J/mm 2 .
