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.
Claims14
A single-ply tissue product comprising a calendered and spirally wound single 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) greater than about 0.0100 J/mm2, a geometric mean tensile (GMT) from about 500 to about 1,500 g/3″ and a sheet bulk greater than about 15.0 cc/g.
A single-ply tissue product comprising a calendered, non-compressively dewatered and spirally wound single ply tissue web, the tissue product having a caliper greater than about 600 μm, a Stiffness Index less than about 7.5 and a Compression Energy (E) greater than about 0.0100 J/mm2.
