Abstract

Fast-wetting (hydrophilic) coform fibrous structures, more particularly fast-wetting composite fibrous structures, for example dry fast-wetting composite fibrous structures, employing a wet-laid fibrous structure such as a paper web, and a coform fibrous structure, multi-ply fibrous structures, for example multi-ply sanitary tissue products such as multi-ply absorbent products for example multi-ply paper towel products, employing one or more fast-wetting composite fibrous structures, and methods for making same.

First claim

What is claimed is:

1. A paper towel comprising a coform fibrous structure, wherein the coform fibrous structure comprises a plurality of solid additives and a plurality of fibrous elements, wherein at least one of the fibrous elements comprises a polymer composition comprising a polymer comprising a polymer chain disrupter and a hydrophilic modifier, such that the paper towel exhibits a Pad Sink Time of greater than 0 seconds to less than 6.0 seconds within less than 30 days after production of the paper towel as measured according to the Pad Sink Test Method, wherein the coform fibrous structure further comprises at least one scrim material; and
a second fibrous structure ply.

2. The paper towel according to claim 1 wherein the plurality of fibrous elements comprises a plurality of filaments.

3. The paper towel according to claim 1 wherein the polymer chain disrupter comprises a copolymer.

4. The paper towel according to claim 1 wherein the at least one scrim material is substantially void of scrim solid additives.

5. The paper towel according to claim 1 wherein the paper towel further comprises a wet-laid fibrous structure.

6. The paper towel according to claim 5 wherein the wet-laid fibrous structure comprises a plurality of fibers.

7. The paper towel according to claim 6 wherein at least one of the fibers comprises a pulp fiber.

8. The paper towel according to claim 7 wherein the pulp fiber comprises a wood pulp fiber.

9. The paper towel according to claim 8 wherein the wood pulp fiber is selected from the group consisting of: hardwood pulp fibers, softwood pulp fibers, and mixtures thereof.

10. The paper towel according to claim 5 wherein the wet-laid fibrous structure comprises an absorbent gel material.

11. The paper towel according to claim 5 wherein the wet-laid fibrous structure comprises a surface having a surface pattern.

12. The paper towel according to claim 11 wherein the surface pattern comprises one or more relatively high density regions and one or more relatively low density regions.

13. The paper towel according to claim 5 wherein a surface of the wet-laid fibrous structure is adjacent to a surface of the coform fibrous structure.

14. The paper towel according to claim 5 wherein the wet-laid fibrous structure comprises at least one scrim material that forms an exterior surface of the paper towel.

15. The paper towel according to claim 5 wherein the paper towel further comprises a second wet-laid fibrous structure.

16. The paper towel according to claim 15 wherein the second wet-laid fibrous structure comprises a surface having a surface pattern.

17. The paper towel according to claim 16 wherein the surface pattern comprises one or more relatively high density regions and one or more relatively low density regions.

18. The paper towel according to claim 1 wherein the paper towel is in the form of a roll.
