Abstract

Scrubby fibrous structures and more particularly scrubby coform fibrous structures and methods for making same are provided.

First claim

What is claimed is:

1 . A fibrous structure comprising:
a. one or more core components; b. one or more scrim components; and c. one or more scrubby components;
wherein the components are different from one another.

2 . The fibrous structure according to claim 1 wherein at least one of the core components comprises a plurality of solid additives.

3 . The fibrous structure according to claim 1 wherein at least one of the core components comprises a plurality of core fibrous elements.

4 . The fibrous structure according to claim 3 wherein at least one of the core components comprises a plurality of solid additives and a plurality of the core fibrous elements.

5 . The fibrous structure according to claim 3 wherein at least one of the core fibrous elements comprises a polymer.

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

7 . The fibrous structure according to claim 6 wherein at least one of the core fibrous elements exhibits an average fiber diameter of less than 50 μm.

8 . The fibrous structure according to claim 1 wherein at least one of the core components comprises one or more scrubby components.

9 . The fibrous structure according to claim 8 wherein at least one of the scrubby components comprises a scrubby element.

10 . The fibrous structure according to claim 9 wherein the scrubby element comprises a scrubby fibrous element.

11 . The fibrous structure according to claim 10 wherein the scrubby fibrous element exhibits an average fiber diameter of less than 250 μm.

12 . The fibrous structure according to claim 1 wherein at least one of the scrim components is adjacent to at least one of the core components.

13 . The fibrous structure according to claim 12 wherein at least one of the core components is positioned between two scrim components.

14 . The fibrous structure according to claim 1 wherein at least one of the scrim components comprises a plurality of scrim fibrous elements.

15 . The fibrous structure according to claim 14 wherein at least one of the scrim fibrous elements exhibits an average fiber diameter of less than 50 μm.

16 . The fibrous structure according to claim 1 wherein at least one of the scrim components comprises one or more scrubby components.

17 . The fibrous structure according to claim 16 wherein at least one of the scrubby components comprises a scrubby element.

18 . The fibrous structure according to claim 17 wherein the scrubby element comprises a scrubby fibrous element.

19 . The fibrous structure according to claim 18 wherein the scrubby fibrous element exhibits an average fiber diameter of less than 250 μm.

20 . The fibrous structure according to claim 17 wherein the scrubby element comprises a textured pattern present on a surface of the scrim component.

21 . The fibrous structure according to claim 1 wherein at least one of the scrubby components comprises a plurality of scrubby fibrous elements.

22 . The fibrous structure according to claim 21 wherein at least one of the scrubby fibrous elements exhibits an average fiber diameter of less than 250 μm.

23 . The fibrous structure according to claim 21 wherein the scrubby component comprises a textured pattern of the scrubby fibrous elements

24 . The fibrous structure according to claim 21 wherein the scrubby fibrous elements are present on a surface of one or more of the scrim components.
