Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
We claim: 1. A rolled tissue product comprising a tissue web spirally wound into a roll, the web having a three-dimensional surface topography comprising a plurality of alternating valleys and ridges, the center of adjacent ridges spaced apart from one another at least about 1.7 mm, a basis weight from about 35 to about 50 gsm, a sheet bulk from about 12 to about 20 cc/g and a Surface Smoothness S90 value from about 70 to about 120 μm. 2. The tissue product of claim 1 wherein the tissue web comprises an uncreped through-air dried web. 3. The tissue product of claim 1 wherein the tissue web has a Stiffness Index from about 6 to about 8 and a GMT from about 700 to about 1400 g/3″. 4. The tissue product of claim 1 wherein the tissue web has a GM Slope from about 4,000 to about 8,000 g/3″. 5. The rolled tissue product of claim 1 wherein the tissue web has a GMS from about 14 to about 18 percent. 6. The rolled tissue product of claim 1 wherein the tissue web is a single-ply through-air dried tissue web. 7. The rolled tissue product of claim 1 wherein the tissue web has a Surface Smoothness S90 value less than about 105 μm. 8. The rolled tissue product of claim 1 wherein the tissue web has a Surface Smoothness S90 value from about 70 to about 105 μm, a Surface Smoothness Sa value less than about 22 μm and a Surface Smoothness Sq value less than about 35 μm.
