Tissue paper having large scale, aesthetically discernible patterns

 David M. Rasch et al
The present invention is directed to a single lamina tissue paper having visually discernible, large scale patterns made during the drying step of the papermaking process. Particularly, the tissue is made on a blow through drying belt having a pattern of alternating knuckles and deflection...

Claims

What is claimed is:

1. A single lamina cellulosic fibrous structure having at least three visually discernible regions, said cellulosic fibrous structure comprising:

a background matrix having a first value of an optically intensive property;
a nonembossed first annular region having a second value of the optically intensive property, said second value being substantially different than said first value of the optically intensive property of said background matrix;
a nonembossed second annular region having a third value of the optically intensive property, said third value being substantially different than said second value of the optically intensive property of said first annular region, said second annular region being disposed substantially within said first annular region; and
a nonembossed third region having a value of the optically intensive property substantially different than said third value of the optically intensive property of said second annular region, said third region being disposed substantially within said second annular region.

2. A cellulosic fibrous structure according to claim 1 wherein said second annular region is generally concentric and generally congruent said first annular region.

3. A cellulosic fibrous structure according to claim 1 wherein said value of the optically intensive property of said third region is substantially equivalent said value of the optically intensive property of said first annular region.

4. A cellulosic fibrous structure according to claim 1 wherein said third region is an annular region.

5. A cellulosic fibrous structure according to claim 4 further comprising a fourth region generally interior said third annular region, said fourth region having a value of the optically intensive property substantially different than said value of the optically intensive property of said third annular region.

6. A cellulosic fibrous structure according to claim 5 wherein said value of the optically intensive property of said fourth region is generally equivalent said first value of the optically intensive property of said background matrix.

7. A cellulosic fibrous structure according to claim 1 wherein said value of the optically intensive property of said third region is substantially equivalent said first value of the optically intensive property of said background matrix.

8. A cellulosic fibrous structure according to claim 1 wherein said first annular region has a density greater than said density of said second annular region.

9. A cellulosic fibrous structure according to claim 8 wherein said third region has a density greater than said density of said second annular region.
