Fibrous structures
Fibrous structures, and more particularly sanitary tissue products containing fibrous structures having a surface exhibiting a three-dimensional (3D) pattern such that the fibrous structure and/or sanitary tissue product exhibits novel properties compared to known fibrous structures and/or sanitary tissue products, and methods for making same are provided.
1. A fibrous structure comprising a surface comprising a three-dimensional surface pattern, wherein the three-dimensional surface pattern comprises one or more pillow regions present in one or more semi-continuous non-pillow regions, wherein the surface exhibits a Total Pillow Perimeter value of at least 30 in/in 2 as measured according to the Total Pillow Perimeter Test Method such that the fibrous structure exhibits a Surface Void Volume value at 1.7 psi of at least 0.090 mm 3 /mm 2 as measured according to the Surface Void Volume Test Method.
2. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Surface Void Volume value at 1.7 psi of at least 0.092 mm 3 /mm 2 as measured according to the Surface Void Volume Test Method.
3. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Surface Void Volume value at 0.88 psi of at least 0.108 mm 3 /mm 2 as measured according to the Surface Void Volume Test Method.
4. The fibrous structure according to claim 1 wherein the fibrous structure comprises a plurality of fibrous elements.
5. The fibrous structure according to claim 4 wherein the plurality of fibrous elements comprise a plurality of fibers.
6. The fibrous structure according to claim 5 wherein at least one of the fibers comprises a pulp fiber.
7. The fibrous structure according to claim 6 wherein the pulp fiber comprises a wood pulp fiber.
8. The fibrous structure according to claim 6 wherein the pulp fiber comprises a non-wood pulp fiber.
9. The fibrous structure according to claim 1 wherein the surface further comprises a surface softening agent.
10. The fibrous structure according to claim 1 wherein the fibrous structure comprises a temporary wet strength agent.
11. The fibrous structure according to claim 1 wherein the three-dimensional surface pattern further comprises one or more semi-continuous pillow regions.
12. The fibrous structure according to claim 1 wherein the three-dimensional surface pattern further comprises one or more discrete knuckle regions.
13. The fibrous structure according to claim 12 wherein the discrete pillow region exhibits a Discrete Pillow Perimeter value of at least 5.00 in/in 2 as measured according to the Total Pillow Perimeter Test Method.
14. The fibrous structure according to claim 13 wherein the discrete pillow region exhibits a Discrete Pillow Perimeter value of at least 10.00 in/in 2 as measured according to the Total Pillow Perimeter Test Method.
15. The fibrous structure according to claim 14 wherein the discrete pillow region exhibits a Discrete Pillow Perimeter value of at least 15.00 in/in 2 as measured according to the Total Pillow Perimeter Test Method.
16. The fibrous structure according to claim 15 wherein the discrete pillow region exhibits a Discrete Pillow Perimeter value of at least 18.00 in/in 2 as measured according to the Total Pillow Perimeter Test Method.
17. The fibrous structure according to claim 1 wherein the fibrous structure is a toilet tissue.
18. A multi-ply fibrous structure comprising at least one fibrous structure ply comprising the fibrous structure according to claim 1 and a second fibrous structure ply.
19. The multi-ply fibrous structure according to claim 18 wherein the multi-ply fibrous structure is toilet tissue.
20. A method for making a fibrous structure according to claim 1 , the method comprising the steps of:
a. providing a plurality of fibrous elements;
b. collecting the fibrous elements on a collection device to form a fibrous structure; and
c. imparting a three-dimensional surface pattern to a surface of the fibrous structure such that the fibrous structure comprises a three-dimensional surface pattern comprising one or more pillow regions present in one or more semi-continuous non-pillow regions, wherein the surface of the fibrous structure exhibits a Total Pillow Perimeter of at least 30 in/in 2 as measured according to the Total Pillow Perimeter Test Method such that the fibrous structure exhibits a Surface Void Volume value at 1.7 psi of at least 0.090 mm 3 /mm 2 as measured according to the Surface Void Volume Test Method.
