Abstract

A tissue with two surfaces having elevated regions is provided. The elevated regions can be imparted onto the surfaces of the tissue utilizing various papermaking techniques and devices, such as using patterned fabrics, wire-mesh, and/or pressure rolls. A tissue of the present invention can have a substantial fiber density gradient in the -z direction and a relatively low fiber density gradient in the x-y plane. Moreover, the tissue can also have a substantial pore size distribution gradient in the -z direction and a relatively low pore size distribution gradient in the x-y plane for improved absorption properties.

Claims (35)

1. An article of manufacture comprising:
a tissue having a first surface and a second surface, said first surface of said tissue having elevated regions forming a first topography, said second surface of said tissue having elevated regions forming a second topography that differs in at least one topographical characteristic from said first topography, wherein said tissue has a higher fiber density gradient in the -z direction than in the x-y plane.
2. An article of manufacture as defined in claim 1, wherein said at least one topographical characteristic is selected from the group consisting of pitch depth, pitch width, direction, number of elevated regions per unit area, and combinations thereof.
3. An article of manufacture as defined in claim 1, wherein said second surface is imparted with at least 50% more elevated regions per square inch than said first surface.
4. An article of manufacture as defined in claim 1, wherein said second surface is imparted with between about 50% to about 300% more elevated regions per square inch than said first surface.
5. An article of manufacture as defined in claim 1, wherein said elevated regions of said second surface have a pitch depth of between about 20% to about 100% greater than the pitch depth of said elevated regions of said first surface.
6. An article of manufacture as defined in claim 1, wherein said tissue has a higher pore size distribution gradient in the -z direction than in the x-y plane.
7. An article of manufacture as defined in claim 1, wherein said fibers contain pulp fibers.
8. An article of manufacture as defined in claim 1, wherein said tissue has a basis weightless than about 120 grams per square meter.
9. An article of manufacture as defined in claim 1, wherein said tissue has a basis weight less than about 60 grams.
10. An article of manufacture as defined in claim 1, wherein said tissue contains multiple plies.
11. An article of manufacture as defined in claim 10, wherein one ply defines said first surface and another ply defines said second surface.
12. An article of manufacture as defined in claim 10, wherein one ply defines said first surface and said second surface.
13. A tissue comprising:
a fibrous web containing pulp fibers having a first surface and a second surface, said first surface of said fibrous web having elevated regions forming a first topography, said second surface of said fibrous web having elevated regions forming a second topography that differs in at least one topographical characteristic from said first topography, wherein said fibrous web has a higher fiber density gradient in the -z direction than in the x-y plane and a higher pore size distribution gradient in the -z direction than in the x-y plane.
14. A tissue as defined in claim 13, wherein said at least one topographical characteristic is selected from the group consisting of pitch depth, pitch width, direction, number of elevated regions per unit area, and combinations thereof.
15. A tissue as defined in claim 13, wherein said second surface is imparted with at least 50% more elevated regions per square inch than said first surface.
16. A tissue as defined in claim 13, wherein said second surface is imparted with between about 50% to about 300% more elevated regions per square inch than said first surface.
17. A tissue as defined in claim 13, wherein said elevated regions of said second surface have a pitch depth of between about 20% to about 100% greater than the pitch depth of said elevated regions of said first surface.
18. A tissue as defined in claim 13, wherein said tissue contains multiple plies, wherein one of said plies comprises said fibrous web such that an outer surface of said tissue is formed by said first surface of said fibrous web.
19. A tissue as defined in claim 18, further comprising a second fibrous web containing pulp fibers having a first surface and a second surface, said first surface of said fibrous web having elevated regions forming a third topography, said second surface of said fibrous web having elevated regions forming a fourth topography that differs in at least one topographical characteristic from said third topography, wherein said second fibrous web has a higher fiber density gradient in the -z direction than in the x-y plane and a higher pore size distribution gradient in the -z direction than in the x-y plane.
20. A tissue as defined in claim 19, wherein another one of said plies comprises said second fibrous web such that the other outer surface of said tissue is formed by said first surface of said second fibrous web.
21. A process comprising the steps of:
providing a paper web containing fibers having a first surface and a second surface;
contacting said first surface of said paper web with a first device containing protrusions so that said protrusions of said first device impart said first surface with elevated regions, said elevated regions of said first surface forming a first topography; and contacting said second surface of said paper web with a second device containing protrusions so that said protrusions of said second device impart said second surface with elevated regions, said elevated regions of said second surface forming a second topography that differs in at least one topographical characteristic from said first topography, wherein said paper web has a higher fiber density gradient in the -z direction than in the x-y plane.
22. A process as defined in claim 21, wherein said first device is selected from the group consisting of a fabric, wire-mesh, and a roll.
23. A process as defined in claim 21, wherein said second device is selected from the group consisting of a fabric, wire-mesh, and a roll.
24. A process as defined in claim 21, further comprising the step of applying pressure to said first surface while said first device is contacting said first surface.
25. A process as defined in claim 24, further comprising the step of applying pressure to said second surface while said second device is contacting said second surface.
26. A process as defined in claim 24, wherein said pressure applied to said first surface is less than about 60 pounds per square inch.
27. A process as defined in claim 24, wherein said pressure applied to said first surface is between about 35 to about 45 pounds per square inch.
28. A process as defined in claim 21, further comprising the step of applying pressure to said second surface while said second device is contacting said second surface.
29. A process as defined in claim 28, wherein said pressure applied to said second surface is less than about 60 pounds per square inch.
30. A process as defined in claim 28, wherein said pressure applied to said second surface is between about 35 to about 45 pounds per square inch.
31. A process as defined in claim 21, further comprising the step of drying said paper web.
32. A process as defined in claim 31, wherein said drying step is accomplished by through-air drying.
33. A process as defined in claim 21, wherein said at least one topographical characteristic is selected from the group consisting of pitch depth, pitch width, direction, number of elevated regions per unit area, and combinations thereof.
34. A process as defined in claim 21, wherein said second surface is imparted with at least 50% more elevated regions per square inch than said first surface.
