Abstract

Articles, such as sanitary tissue products, including fibrous structures, and more particularly articles including fibrous structures having a plurality of fibrous elements wherein the article exhibits differential cellulose content throughout the thickness of the article and methods for making same are provided.

Claims (20)

1. A fibrous structure comprising a paper web and a plurality of filaments, wherein the plurality of filaments are spun onto the paper web such that the fibrous structure exhibits a CRT Rate of greater than 0.33 g/sec as measured according to the Absorptive Rate and Capacity (CRT) Test Method and a Wet Web-Web CoF of less than 1.85 as measured according to the Wet Web-Web CoF Test Method.

2. The fibrous structure according to claim 1 wherein the paper web comprises pulp fibers.

3. The fibrous structure according to claim 2 wherein the pulp fibers comprise wood pulp fibers.

4. The fibrous structure according to claim 1 wherein at least one of the plurality of filaments comprises a polymer.

5. The fibrous structure according to claim 4 wherein the polymer comprises a thermoplastic polymer.

6. The fibrous structure according to claim 5 wherein the thermoplastic polymer comprises a polyolefin.

7. The fibrous structure according to claim 6 wherein the polyolefin is selected from the group consisting of: polypropylene, polyethylene, and mixtures thereof.

8. The fibrous structure according to claim 4 wherein the polymer comprises a compostable polymer.

9. The fibrous structure according to claim 4 wherein the polymer is selected from the group consisting of: polylactic acid, polyhydroxyalkanoate, polyesteramide, polycaprolactone, and mixtures thereof.

10. The fibrous structure according to claim 1 wherein the fibrous structure further exhibits a TS7 of less than 17.80 dB V 2 rms as measured according to the Emtec Test Method.

11. A fibrous structure comprising a paper web and a plurality of filaments, wherein the plurality of filaments are spun onto the paper web such that the fibrous structure exhibits an HFS of greater than 17.0 g/g as measured according to the Horizontal Full Sheet (HFS) Test Method and a Wet Web-Web CoF of greater than 1.85 as measured according to the Wet Web-Web CoF Test Method.

12. The fibrous structure according to claim 11 wherein the paper web comprises pulp fibers.

13. The fibrous structure according to claim 12 wherein the pulp fibers comprise wood pulp fibers.

14. The fibrous structure according to claim 11 wherein at least one of the plurality of filaments comprises a polymer.

15. The fibrous structure according to claim 14 wherein the polymer comprises a thermoplastic polymer.

16. The fibrous structure according to claim 15 wherein the thermoplastic polymer comprises a polyolefin.

17. The fibrous structure according to claim 16 wherein the polyolefin is selected from the group consisting of: polypropylene, polyethylene, and mixtures thereof.

18. The fibrous structure according to claim 14 wherein the polymer comprises a compostable polymer.

19. The fibrous structure according to claim 14 wherein the polymer is selected from the group consisting of: polylactic acid, polyhydroxyalkanoate, polyesteramide, polycaprolactone, and mixtures thereof.

20. The fibrous structure according to claim 11 wherein the fibrous structure further exhibits a TS7 of less than 17.80 dB V 2 rms as measured according to the Emtec Test Method.
