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.

First claim

What is claimed is:

1. A fibrous structure comprising a paper web comprising a plurality of fibers and a coform fibrous structure comprising a plurality of filaments comprising a compostable polymer, wherein the plurality of filaments of the coform fibrous structure are spun onto the paper web such that the fibrous structure exhibits a CRT Rate of greater than 0.35 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 compostable polymer comprises a thermoplastic polymer.

3. The fibrous structure according to claim 2 wherein the thermoplastic polymer comprises a polyolefin.

4. The fibrous structure according to claim 3 wherein the polyolefin is selected from the group consisting of: polypropylene, polyethylene, and mixtures thereof.

5. The fibrous structure according to claim 1 wherein at least one of the plurality of fibers is a pulp fiber.

6. The fibrous structure according to claim 1 wherein the fibrous structure further exhibits a Bending Modulus of less than 10.00 milligram·cm·grams/mils 3 as measured according to the Flexural Rigidity and Bending Modulus Test Method.

7. The fibrous structure according to claim 1 wherein the fibrous structure further exhibits a TS7 of less than 17.0 dB V 2 rms as measured according to the Emtec Test Method.

8. A fibrous structure comprising a paper web and a plurality of fibers and 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.

9. The fibrous structure according to claim 8 wherein at least one of the filaments comprises a polymer.

10. The fibrous structure according to claim 9 wherein the polymer comprises a thermoplastic polymer.

11. The fibrous structure according to claim 10 wherein the thermoplastic polymer comprises a polyolefin.

12. The fibrous structure according to claim 8 wherein the fibrous structure comprises a coform fibrous structure.

13. The fibrous structure according to claim 8 wherein at least one of the plurality of fibers is a pulp fiber.

14. The fibrous structure according to claim 13 wherein the pulp fiber is a wood pulp fiber.

15. The fibrous structure according to claim 8 wherein the fibrous structure further exhibits a Bending Modulus of less than 10.00 milligram·cm·grams/mils 3 as measured according to the Flexural Rigidity and Bending Modulus Test Method.

16. The fibrous structure according to claim 8 wherein the fibrous structure further exhibits a TS7 of less than 17.0 dB V 2 rms as measured according to the Emtec Test Method.
