Abstract

Fibrous structures that exhibit a Free Fiber End Count greater than the Free Fiber End Count of known fibrous structures in the range of free fiber end lengths of from about 0.10 mm to about 0.75 mm as determined by the Free Fiber End Test Method, and sanitary tissue products comprising same and methods for making same are provided.

Claims (15)

1. A creped fibrous structure comprising a plurality of fibers and a plurality of uninterrupted, wet-textured line elements, wherein at least one line element is substantially machine direction oriented and sinusoidal and has a Zone 1 having a first width and a Zone 2 having a second width, wherein the second width is less than the first width and the plurality of fibers comprises trichome fibers and the creped fibrous structure exhibits a Free Fiber End Count of greater than 130 to about 155 in the range of free fiber end lengths of from about 0.1 mm to about 0.25 mm as determined by the Free Fiber End Test Method.

2. The creped fibrous structure according to claim 1 wherein the plurality of fibers further comprises wood pulp fibers, wherein the wood pulp fibers are selected from the group consisting of hardwood pulp fibers, softwood pulp fibers and mixtures thereof.

3. The creped fibrous structure according to claim 2 wherein the hardwood pulp fibers comprise eucalyptus pulp fibers.

4. The creped fibrous structure according to claim 1 wherein greater than 50% by weight of the plurality of fibers comprises fibers selected from the group consisting of: trichome fibers, hardwood pulp fibers and mixtures thereof.

5. The creped fibrous structure according to claim 1 wherein the fibrous structure exhibits a basis weight of greater than 15 gsm to about 120 gsm as measured according to the Basis Weight Test Method.

6. The creped fibrous structure according to claim 1 wherein the fibrous structure is a layered fibrous structure.

7. The creped fibrous structure according to claim 1 wherein the fibrous structure is a homogeneous fibrous structure.

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

9. A creped fibrous structure comprising a plurality of fibers and a plurality of uninterrupted, wet-textured line elements, wherein at least one line element is substantially machine direction oriented and sinusoidal and has a Zone 1 having a first width and a Zone 2 having a second width, wherein the second width is less than the first width and the plurality of fibers comprises trichome fibers and the creped fibrous structure exhibits a Free Fiber End Count of greater than 160 to about 205 in the range of free fiber end lengths of from about 0.25 mm to about 0.50 mm as determined by the Free Fiber End Test Method.

10. The creped fibrous structure according to claim 9 wherein the plurality of fibers further comprises wood pulp fibers wherein the wood pulp fibers are selected from the group consisting of hardwood pulp fibers, softwood pulp fibers and mixtures thereof.

11. The creped fibrous structure according to claim 10 wherein the hardwood pulp fibers comprise eucalyptus pulp fibers.

12. The creped fibrous structure according to claim 9 wherein greater than 50% by weight of the plurality of fibers comprises fibers selected from the group consisting of: trichome fibers, hardwood pulp fibers and mixtures thereof.

13. The creped fibrous structure according to claim 9 wherein the fibrous structure is a layered fibrous structure.

14. The creped fibrous structure according to claim 9 wherein the fibrous structure is a homogeneous fibrous structure.

15. A single- or multi-ply sanitary tissue product comprising a creped fibrous structure according to claim 9 .
