Abstract

Fibrous elements, such as filaments and/or fibers, and more particularly to fibrous elements that contain a fast wetting surfactant, fibrous structures made therefrom, and methods for making same are provided.

First claim

What is claimed is:

1. A multi-ply toilet tissue comprising a monocomponent fibrous element produced from an aqueous polymer melt composition void of thermoplastic water-insoluble polymers and comprising a blend comprising a monocomponent non-thermoplastic fibrous element-forming polymer, water, and a branched fast wetting surfactant selected from the group consisting of: sulfosuccinate surfactants, alcohol sulfate surfactants derived from branched alcohols, paraffin sulfonates, and mixtures thereof wherein the branched fast wetting surfactant facilitates removal of water from the monocomponent fibrous element during formation from the aqueous polymer melt composition, wherein the fibrous element exhibits greater than 50% fast wetting surfactant recovery after extraction with water according to the Determination of Total Free Surfactant in Fibrous Structure Using Water Extraction/HPLC Test Method.

2. The multi-ply toilet tissue according to claim 1 wherein the fibrous element-forming polymer comprises a hydroxyl polymer.

3. The multi-ply toilet tissue according to claim 2 wherein the hydroxyl polymer comprises a polysaccharide.

4. The multi-ply toilet tissue according to claim 1 wherein the fibrous element-forming polymer is selected from the group consisting of: polyvinyl alcohol, polyvinyl alcohol derivatives, polyvinyl alcohol copolymers, gums, arabinans, galactans, proteins, and mixtures thereof.

5. The multi-ply toilet tissue according to claim 1 wherein the blend comprises two or more fibrous element-forming polymers.

6. The multi-ply toilet tissue according to claim 1 wherein the fast wetting surfactant is selected from the group consisting of: anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic surfactants, and mixtures thereof.

7. The multi-ply toilet tissue according to claim 1 wherein the fast wetting surfactant comprises a sulfosuccinate surfactant.

8. The multi-ply toilet tissue according to claim 1 wherein the blend further comprises a non-hydroxyl polymer selected from the group consisting of: polyacrylamide and its derivatives; polyacrylic acid, polymethacrylic acid, and their esters; polyethyleneimine; copolymers made from mixtures of monomers of the aforementioned polymers; and mixtures thereof.

9. The multi-ply toilet tissue according to claim 8 wherein the non-hydroxyl polymer comprises polyacrylamide.

10. The multi-ply toilet tissue according to claim 1 wherein the fibrous element comprises a filament.

11. The multi-ply toilet tissue according to claim 1 wherein the multi-ply toilet tissue comprises a plurality of fibrous elements according to claim 1 .

12. The multi-ply toilet tissue according to claim 1 wherein the multi-ply toilet tissue exhibits a basis weight of from about 10 g/m 2 to about 120 g/m 2 .

13. The multi-ply toilet tissue according to claim 11 wherein the multi-ply toilet tissue further comprises one or more solid additives.

14. The multi-ply toilet tissue according to claim 13 wherein at least one of the one or more solid additives comprises a fiber.

15. The multi-ply toilet tissue according to claim 13 wherein the multi-ply toilet tissue further comprises a scrim connected to the surface of the multi-ply toilet tissue such that the solid additives are positioned between the scrim and the surface of the multi-ply toilet tissue.

16. The multi-ply toilet tissue according to claim 1 wherein the fibrous element is a crosslinked fibrous element.

17. A multi-ply toilet tissue roll comprising a multi-ply toilet tissue according to claim 1 .
