Abstract

Fibrous structures, for example toilet tissue, having a surface including a plurality of fibrous elements, such as a plurality of hydroxyl polymer filaments that exhibit an average fiber diameter of less than 2 μm as measured according to the Surface Average Fiber Diameter Test Method such that the fibrous structure exhibits a Dual Surface Glide Value of less than 17.7 g as measured according to the Glide Test Method—3 Inch Sample and method for making same is provided.

Claims (21)

1. A fibrous structure comprising a plurality of fibrous elements, wherein the fibrous structure comprises a surface comprising a plurality of hydroxyl polymer filaments that exhibit an average fiber diameter of less than 2 μm as measured according to the Surface Average Fiber Diameter Test Method such that the fibrous structure exhibits a Dual Surface Glide Value of less than 17.7 g as measured according to the Glide Test Method—3 Inch Sample.

2. The fibrous structure according to claim 1 wherein the plurality of fibrous elements comprises fibers.

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

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

5. The fibrous structure according to claim 1 wherein the plurality of fibrous elements are present in the form of a paper web.

6. The fibrous structure according to claim 5 wherein the paper web is a wet laid fibrous structure.

7. The fibrous structure according to claim 6 wherein the wet laid fibrous structure comprises a patterned wet laid fibrous structure.

8. The fibrous structure according to claim 5 wherein the paper web is an embossed fibrous structure.

9. The fibrous structure according to claim 1 wherein the plurality of fibrous elements comprises filaments.

10. The fibrous structure according to claim 1 wherein the plurality of fibrous elements comprises fibers and filaments.

11. The fibrous structure according to claim 1 wherein the hydroxyl polymer filaments of the surface comprise polyvinyl alcohol filaments.

12. The fibrous structure according to claim 1 wherein the hydroxyl polymer filaments of the surface comprise a polysaccharide filaments.

13. The fibrous structure according to claim 1 wherein the hydroxyl polymer filaments of the surface are present in a first layer of hydroxyl polymer filaments comprising polyvinyl alcohol and a second layer of hydroxyl polymer filaments comprising a polysaccharide.

14. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Dual Surface Glide Value of less than 17.7 g as measured according to the Glide Test Method—4 Inch Sample.

15. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Single Surface Glide Value of less than 12.7 g as measured according to the Glide Test Method—3 Inch Sample.

16. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Single Surface Glide Value of less than 12.7 g as measured according to the Glide Test Method—4 Inch Sample.

17. A roll of fibrous structure comprising a fibrous structure according to claim 1 .

18. A package comprising one or more rolls of fibrous structure according to claim 17 .

19. A method for making a fibrous structure according to claim 1 , the method comprising the steps of:

a. providing a fibrous structure comprising a plurality of fibrous elements; and

b. applying a plurality of hydroxyl polymer filaments that exhibit an average fiber diameter of less than 2 μm onto a surface of the fibrous structure such that the fibrous structure exhibits a Dual Surface Glide Value of less than 17.7 g as measured according to the Glide Test Method—3 Inch Sample.
