Abstract

The present invention provides multi-ply tissue products having distinctly different first and second outer surfaces or sides. The two-sidedness is generally provided by forming one of the surfaces from a tissue ply having a plurality of macrofolds and the other side from a substantially planar tissue ply. The first ply may be attached to the second ply at longitudinally spaced apart points that define a macrofold therebetween. The length of tissue between the points of attachment may form a wave-like structure having an amplitude and wavelength and having a transversely orientated void that extends from a first edge to a second edge of the tissue. The combination of these elements provides a tissue product that is both aesthetically pleasing and well suited to cleaning due to the large amount of surface area created by the macrofolds.

First claim

What is claimed is:

1. A tissue product having a machine direction (MD) and a cross-machine direction (CD), a first upper surface and an opposed bottom surface, the product comprising:
a first tissue ply having a basis weight from about 10 to about 45 grams per square meter (gsm) and sheet bulk greater than about 5 cubic centimeters per gram (cc/g) and a first MD length,
a second tissue ply having a basis weight from about 10 to about 45 grams per square meter (gsm) and sheet bulk greater than about 5 cubic centimeters per gram (cc/g) and a second MD Length,
a plurality of substantially CD orientated lines of perforation spaced apart from one another in the MD and defining a plurality of sheets therebetween, the sheets having a sheet length (L);
wherein the first MD Length is substantially equal to the sheet length (L) and the second MD Length is at least about 150 percent of the sheet length (L).

2. The tissue product of claim 1 wherein the first ply is substantially planar, and the second ply comprises a plurality of substantially CD orientated macrofolds defined by points of attachment between the first and second plies, the points of attachment being spaced apart from one another in the MD.

3. The tissue product of claim 2 wherein the points of attachment are substantially equally spaced apart from one another a distance from about 5.0 to about 16 mm in the MD.

4. The tissue product of claim 2 wherein the points of attachment extend substantially continuously in the CD.

5. The tissue product of claim 2 wherein each of the plurality of macrofolds are similarly sized and shaped.

6. The tissue product of claim 2 further comprising a plurality of dot embossments disposed on the second ply between the spaced apart points of attachment.

7. The tissue product of claim 1 wherein the second MD Length is from about 120 to about 600 percent of the sheet length (L).
