Abstract

Fibrous structures, for example sanitary tissue products, such as toilet tissue, and more particularly fibrous structures containing a movable surface and methods for making same and methods for making same are provided.

First claim

What is claimed is:

1. A layered fibrous structure comprising a movable surface layer comprising a plurality of fibrous elements that are bonded at bond sites to a web material layer, wherein at least two of the bond sites exhibit an edge-to-edge bond distance of at least 1 mm and wherein at least a portion of the plurality of fibrous elements within the edge-to-edge bond distance between the bond sites are unbonded to the web material layer.

2. The layered fibrous structure according to claim 1 wherein at least one of the fibrous elements comprises a fiber.

3. The layered fibrous structure according to claim 1 wherein at least one of the fibrous elements comprises a filament.

4. The layered fibrous structure according to claim 1 wherein at least one of the fibrous elements comprises a plurality of fibers and at least one of the fibrous elements comprises a plurality of filaments.

5. The layered fibrous structure according to claim 4 wherein the fibrous structure comprises a layered fibrous structure ply wherein a first layer comprises the plurality of fibers and a second layer comprises the plurality of filaments.

6. The layered fibrous structure according to claim 5 wherein the second layer forms at least a portion of an exterior surface of a toilet tissue.

7. The layered fibrous structure according to claim 6 wherein a scrim material is present on at least a portion of the second layer.

8. The layered fibrous structure according to claim 7 wherein the scrim material comprises filaments.

9. The layered fibrous structure according to claim 8 wherein the scrim material filaments comprise polyvinyl alcohol.

10. The layered fibrous structure according to claim 1 wherein the layered fibrous structure comprises two or more fibrous structure plies.

11. The layered fibrous structure according to claim 10 wherein the layered fibrous structure comprises a first fibrous structure ply adhesively bonded to a second fibrous structure ply.

12. The layered fibrous structure according to claim 1 wherein the edge-to-edge bond distance is at least 1.5 mm.

13. The layered fibrous structure according to claim 1 wherein the layered fibrous structure exhibits a caliper of greater than 20.0 mils as measured according to a Caliper Test Method.

14. The layered fibrous structure according to claim 1 wherein the layered fibrous structure exhibits a caliper of from about 27.0 to about 32.0 mils as measured according to a Caliper Test Method.

15. The layered fibrous structure according to claim 1 wherein the layered fibrous structure exhibits a Capacity Rate Tester (CRT) Capacity of greater than 15 g/g as measured according to a Capacity Rate Tester (CRT) Test Method.

16. The layered fibrous structure according to claim 1 wherein the layered fibrous structure exhibits a Plate Stiffness of less than about 10 N*mm as measured according to a Plate Stiffness Test Method.

17. The layered fibrous structure according to claim 1 wherein the layered fibrous structure exhibits a Capacity Rate Tester (CRT) Rate of less than about 1.0 g/sec as measured according to a Capacity Rate Tester (CRT) Test Method.

18. The layered fibrous structure according to claim 1 wherein the layered fibrous structure comprises a structured fibrous structure ply.

19. A sanitary tissue product comprising a fibrous structure according to claim 1 .

20. A roll of fibrous structure comprising a fibrous structure according to claim 1 .
