Abstract

Thick and absorbent and/or flexible toilet tissue and methods for making same are provided.

First claim

What is claimed is:

1. A multi-ply toilet tissue comprising at least one fibrous structure ply comprising a plurality of fibrous elements, wherein the multi-ply toilet tissue exhibits a caliper of greater than 20.0 mils as measured according to a Caliper Test Method and a Capacity Rate Tester (CRT) Capacity of greater than 15 g/g as measured according to a Capacity Rate Tester (CRT) Test Method.

2. The multi-ply toilet tissue according to claim 1 wherein the caliper is from about 27.0 to about 32.0 mils as measured according to the Caliper Test Method.

3. The multi-ply toilet tissue according to claim 1 wherein the Capacity Rate Tester (CRT) Capacity is from about 20 g/g to about 28 g/g as measured according to the Capacity Rate Tester (CRT) Test Method.

4. The multi-ply toilet tissue according to claim 1 wherein the multi-ply toilet tissue exhibits a Capacity Rate Tester (CRT) Rate of less than about 1.0 g/sec as measured according to the Capacity Rate Tester (CRT) Test Method.

5. The multi-ply toilet tissue according to claim 1 wherein the multi-ply toilet tissue exhibits a Total Wet Decay of greater than 30% as measured according to a Wet Decay Test Method.

6. The multi-ply toilet tissue according to claim 1 wherein the multi-ply toilet tissue exhibits an Initial Total Wet Tensile of greater than 30 g/in as measured according to a Wet Tensile Test Method.

7. The multi-ply toilet tissue according to claim 1 wherein the at least one fibrous structure ply comprises a structured fibrous structure ply.

8. The multi-ply toilet tissue according to claim 1 wherein the plurality of fibrous elements comprises pulp fibers.

9. The multi-ply toilet tissue according to claim 1 wherein the plurality of fibrous elements comprises filaments selected from the group consisting of: polyvinyl alcohol filaments, polysaccharide filaments, polysaccharide derivative filaments, and combinations thereof.

10. The multi-ply toilet tissue according to claim 1 wherein the multi-ply toilet tissue further comprises a second fibrous structure ply.

11. A multi-ply toilet tissue comprising at least one fibrous structure ply comprising a plurality of fibrous elements, wherein the multi-ply toilet tissue exhibits a caliper of greater than 20.0 mils as measured according to a Caliper Test Method and a Plate Stiffness of less than 8.00 N*mm as measured according to a Plate Stiffness Test Method.

12. The multi-ply toilet tissue according to claim 11 wherein the caliper is from about 27.0 to about 32.0 mils as measured according to the Caliper Test Method.

13. The multi-ply toilet tissue according to claim 11 wherein the multi-ply toilet tissue exhibits a Capacity Rate Tester (CRT) Capacity of from about 20 g/g to about 28 g/g as measured according to a Capacity Rate Tester (CRT) Test Method.

14. The multi-ply toilet tissue according to claim 11 wherein the multi-ply toilet tissue 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.

15. The multi-ply toilet tissue according to claim 11 wherein the multi-ply toilet tissue exhibits a Total Wet Decay of greater than 30% as measured according to a Wet Decay Test Method.

16. The multi-ply toilet tissue according to claim 11 wherein the multi-ply toilet tissue exhibits an Initial Total Wet Tensile of greater than 30 g/in as measured according to a Wet Tensile Test Method.

17. The multi-ply toilet tissue according to claim 11 wherein the at least one fibrous structure ply comprises a structured fibrous structure ply.

18. The multi-ply toilet tissue according to claim 11 wherein the plurality of fibrous elements comprises pulp fibers.

19. The multi-ply toilet tissue according to claim 11 wherein the plurality of fibrous elements comprises filaments selected from the group consisting of: polyvinyl alcohol filaments, polysaccharide filaments, polysaccharide derivative filaments, and combinations thereof.

20. The multi-ply toilet tissue according to claim 11 wherein the multi-ply toilet tissue further comprises a second fibrous structure ply.
