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.

Claims15

Dependent claims

A method of manufacturing a soft and resilient tissue product comprising the steps of:

a. forming a fiber slurry;
b. depositing the fiber slurry on a forming fabric;
c. partially dewatering the slurry to form a wet tissue web;
d. transferring the wet tissue web to a through-air drying fabric comprising a support structure and a plurality of linear elements extending in the z-direction therefrom, the elements having a height from about 0.4 to about 0.7 mm;
e. through-air drying the wet tissue web to form a dried tissue web;
and
f. calendering the dried tissue web and winding the calendered web into a rolled tissue product having a Roll Firmness less than about 7.0 mm and a sheet bulk of 15.0 cc/g or greater.
