Abstract

Fibrous structures and more particularly to fibrous structures that exhibit improved TEWL properties, for example lower TEWL % Difference Values as measured according to the TEWL Test Method described herein, compared to known fibrous structures, sanitary tissue products comprising such fibrous structures and method for making such fibrous structures are provided.

First claim

What is claimed is:

1 . A fibrous structure comprising a first web material comprising a plurality of fibers, wherein the fibrous structure exhibits a TEWL % Difference Value (Wipe 144 Day 5) of less than 42.0% as measured according to the TEWL Test Method.

2 . The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Force Variability Value of less than 1.40 as measured according to the Glide on Skin Test Method.

3 . The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Force to Drag Values of less than 100 as measured according to the Glide on Skin Test Method.

4 . The fibrous structure according to claim 1 wherein the first web material comprises a plurality of fibrous elements.

5 . The fibrous structure according to claim 4 wherein at least one of the fibrous elements comprises a fiber.

6 . The fibrous structure according to claim 5 wherein the fiber comprises a pulp fiber.

7 . The fibrous structure according to claim 6 wherein the pulp fiber comprises a wood pulp fiber.

8 . The fibrous structure according to claim 1 wherein the first web material comprises a wet laid fibrous structure ply.

9 . The fibrous structure according to claim 1 wherein the surface of the fibrous structure further comprises at least a portion of the first web material.

10 . The fibrous structure according to claim 1 wherein the surface material is associated with the first web material.

11 . The fibrous structure according to claim 10 wherein the surface material is associated with the first web material through one or more bond sites.

12 . The fibrous structure according to claim 1 wherein the surface material comprises a second web material.

13 . The fibrous structure according to claim 12 wherein the second web material comprises a plurality of fibrous elements.

14 . The fibrous structure according to claim 13 wherein the fibrous elements comprises a non-naturally occurring fiber.

15 . The fibrous structure according to claim 14 wherein the non-naturally occurring fiber comprises a polysaccharide.

16 . The fibrous structure according to claim 15 wherein the polysaccharide is selected from the group consisting of: cellulose, cellulose derivatives, starch, starch derivatives, hemicelluloses, hemicelluloses derivatives, and mixtures thereof

17 . The fibrous structure according to claim 13 wherein at least one of the fibrous elements comprises a filament.

18 . The fibrous structure according to claim 17 wherein the filament comprises polyvinyl alcohol.

19 . The fibrous structure according to claim 17 wherein the filament comprises a polysaccharide.

20 . The fibrous structure according to claim 12 wherein the second web material comprises a crosslinked polymer.
