Abstract
A highly absorbent tissue product is provided having a uniform density and a three-dimensional structure including at least first and second background regions separated by a visually distinctive transition region. The first and second background regions include a series of parallel ridges and depressions extending in the machine direction.
Claims22
A sheet material comprising:
- tissue material having a substantially uniform density and having a machine direction;
- a first region having alternating ridges and depressions extending substantially parallel with the machine direction;
- a second region having a plurality of alternating ridges and depressions extending substantially parallel to the machine direction, wherein the ridges and depressions within the first and second regions have a substantially uniform width, wherein the ridges within the first and second regions have a substantially equal width, wherein the depressions within the first and second regions have a substantially equal width, and wherein the depressions have a greater width then said ridges;
- a visually distinctive transition region separating said first and second regions;
- and
- wherein the ridges within the first region are laterally offset from the ridges within the second region and the depressions within the first region are laterally offset from the depressions within the second region.
