Sanitary tissue products employing fibrous structures that exhibit novel compressibility properties alone and in combination with plate stiffness properties and methods for making same.
First claim
Opening claim text (preview).
What is claimed is: 1. A sanitary tissue product comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Compressibility of greater than 46.0 mils/(log(g/in 2 )) as measured according to the Stack Compressibility and Resilient Bulk Test Method and a Plate Stiffness of less than 5.20 N*mm as measured according to the Plate Stiffness Test Method. 2. The sanitary tissue product according to claim 1 wherein the pulp fibers comprise wood pulp fibers. 3. The sanitary tissue product according to claim 1 wherein the pulp fibers comprise non-wood pulp fibers. 4. The sanitary tissue product according to claim 1 wherein the sanitary tissue product comprises an embossed fibrous structure ply. 5. The sanitary tissue product according to claim 1 wherein the sanitary tissue product comprises a 3D patterned fibrous structure ply. 6. The sanitary tissue product according to claim 5 wherein the 3D patterned fibrous structure ply comprises a through-air-dried fibrous structure ply. 7. The sanitary tissue product according to claim 5 wherein the 3D patterned fibrous structure ply comprises a fabric creped fibrous structure ply. 8. The sanitary tissue product according to claim 5 wherein the 3D patterned fibrous structure ply comprises a belt creped fibrous structure ply. 9. The sanitary tissue product according to claim 1 wherein the sanitary tissue product comprises a conventional wet-pressed fibrous structure ply. 10. A sanitary tissue product comprising at least one creped through-air-dried fibrous structure ply, wherein the sanitary tissue product exhibits a Compressibility of greater than 36.0 mils/(log(g/in 2 )) as measured according to the Stack Compressibility and Resilient Bulk Test Method and a Plate Stiffness of less than 5.20 N*mm as measured according to the Plate Stiffness Test Method. 11. The sanitary tissue product according to claim 10 wherein the pulp fibers comprise wood pulp fibers. 12. The sanitary tissue product according to claim 10 wherein the pulp fibers comprise non-wood pulp fibers. 13. A multi-ply sanitary tissue product comprising at least one 3D patterned fibrous structure ply comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Compressibility of greater than 36.0 mils/(log(g/in 2 )) as measured according to the Stack Compressibility and Resilient Bulk Test Method and a Plate Stiffness of less than 5.20 N*mm as measured according to the Plate Stiffness Test Method. 14. The multi-ply sanitary tissue product according to claim 13 wherein the pulp fibers comprise wood pulp fibers. 15. The multi-ply sanitary tissue product according to claim 13 wherein the pulp fibers comprise non-wood pulp fibers. 16. The multi-ply sanitary tissue product according to claim 13 wherein the 3D patterned fibrous structure ply is an embossed 3D patterned fibrous structure ply. 17. The multi-ply sanitary tissue product according to claim 16 wherein the 3D patterned fibrous structure ply is a 3D patterned through-air-dried fibrous structure ply. 18. The multi-ply sanitary tissue product according to claim 17 wherein the 3D patterned through-air-dried fibrous structure ply is a non-lotioned through-air-dried fibrous structure ply. 19. The multi-ply sanitary tissue product according to claim 16 wherein the 3D patterned fibrous structure ply comprises a fabric creped fibrous structure ply. 20. The multi-ply sanitary tissue product according to claim 16 wherein the 3D patterned through-air-dried fibrous structure ply is a belt creped fibrous structure ply.
