Abstract

Fibrous structures, more particularly non-woven fibrous structures that exhibit properties that consumers associate with cloths, sanitary tissue products incorporating such fibrous structures and processes for making such fibrous structures are provided.

Claims (27)

1. A wet-laid fibrous structure comprising from about 10% to about 100% by weight on a dry fibrous structure basis of naturally occurring fibers and a plurality of tufts, wherein the fibrous structure exhibits a Wet Caliper of greater than 25 mils and a Flex Modulus of less than about 0.25 GM Bmean.

2. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a wet caliper of greater than about 26 mils.

3. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Flex Modulus of less than about 0.24 GM Bmean.

4. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a basis weight of less than about 120 g/m 2 .

5. The fibrous structure according to claim 1 wherein the fibrous structure comprises an embossment.

6. The fibrous structure according to claim 1 wherein the fibrous structure comprises two or more regions that exhibit different densities.

7. The fibrous structure according to claim 1 wherein the fibrous structure comprises a surface comprising undulations.

8. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 1 .

9. The sanitary tissue product according to claim 8 wherein the sanitary tissue product is in roll form.

10. A wet-laid fibrous structure comprising from about 10% to about 100% by weight on a dry fibrous structure basis of naturally occurring fibers and a plurality of tufts, wherein the fibrous structure exhibits a wet caliper of greater than 23 mils and a VFS of greater than 10.2 g/g.

11. The fibrous structure according to claim 10 wherein the fibrous structure exhibits a wet caliper of greater than about 24 mils.

12. The fibrous structure according to claim 10 wherein the fibrous structure exhibits a VFS of greater than about 10.4 g/g.

13. The fibrous structure according to claim 10 wherein the fibrous structure exhibits a basis weight of less than about 120 g/m 2 .

14. The fibrous structure according to claim 10 wherein the fibrous structure comprises an embossment.

15. The fibrous structure according to claim 10 wherein the fibrous structure comprises two or more regions that exhibit different densities.

16. The fibrous structure according to claim 10 wherein the fibrous structure comprises a surface comprising undulations.

17. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 10 .

18. The sanitary tissue product according to claim 17 wherein the sanitary tissue product is in roll form.

19. A wet-laid fibrous structure comprising from about 10% to about 100% by weight on a dry fibrous structure basis of naturally occurring fibers and a plurality of tufts, wherein the fibrous structure exhibits a dry caliper of greater than 31 mils and a VFS of greater than about 9.6 g/g.

20. The fibrous structure according to claim 19 wherein the fibrous structure exhibits a dry caliper of greater than 32 mils.

21. The fibrous structure according to claim 19 wherein the fibrous structure exhibits a VFS of greater than about 9.8 g/g.

22. The fibrous structure according to claim 19 wherein the fibrous structure exhibits a basis weight of less than about 120 g/m 2 .

23. The fibrous structure according to claim 19 wherein the fibrous structure comprises an embossment.

24. The fibrous structure according to claim 19 wherein the fibrous structure comprises two or more regions that exhibit different densities.

25. The fibrous structure according to claim 19 wherein the fibrous structure comprises a surface comprising undulations.

26. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 19 .

27. The sanitary tissue product according to claim 26 wherein the sanitary tissue product is in roll form.
