Abstract

Hydroxyl polymer polymeric structures, for example fibrous elements, such as filaments and/or fibers, and more particularly to hydroxyl polymer fibrous elements that contain a dual purpose material and/or dual purpose material component, fibrous structures made therefrom, and methods for making same are provided.

First claim

What is claimed is:

1. A fibrous element comprising a fibrous element-forming polymer and a dual purpose material, wherein the dual purpose material exhibits both a crosslinking facilitator function and a fast wetting surfactant function within the same dual purpose material, wherein the dual purpose material has the following Formula I:

wherein MO 3 S consists of M + and − O 3 S, where M + is an ammonium or iminium cation; and R 2 is independently selected from the group consisting of: alkyl, hydroxyalkyl, alkanolamine, aryl, hydroxylaryl, or part of a heterocyclic ring, and where R is a C 1 -C 18 linear or branched alkyl and/or a C 1 -C 12 linear or branched alkyl and/or a C 1 -C 8 linear or branched alkyl group.

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

3. The fibrous element according to claim 2 wherein the hydroxyl polymer comprises a polysaccharide.

4. The fibrous element according to claim 3 wherein the polysaccharide is selected from the group consisting of: starch, starch derivatives, starch copolymers, chitosan, chitosan derivatives, chitosan copolymers, cellulose, cellulose derivatives, cellulose copolymers, hemicellulose, hemicellulose derivatives, hemicellulose copolymers, and mixtures thereof.

5. The fibrous element according to claim 1 wherein the fibrous element further comprises a crosslinking agent is selected from the group consisting of: imidazolidinones, polycarboxylic acids, and mixtures thereof.

6. The fibrous element according to claim 5 wherein the crosslinking agent comprises an imidazolidinone.

7. The fibrous element according to claim 6 wherein the imidazolidinone is dihydroxyethyleneurea.

8. The fibrous element according to claim 1 wherein the dual purpose material is selected from the group consisting of: ammonium sulfosuccinate diester salts, iminium sulfosuccinate diester salts, and mixtures thereof.

9. The fibrous element according to claim 1 wherein M + is an ammonium or iminium cation + NH n R 2 4-n where n is 0-4.

10. The fibrous element according to claim 1 wherein the dual purpose material is produced from an amine and a sulfosuccinic acid diester.

11. The fibrous elements according to claim 1 wherein the dual purpose material is selected from the group consisting of: sulfosuccinic acid bis (isobutyl ester) ammonium salt; sulfosuccinic acid bis(pentyl ester) ammonium salt; sulfosuccinic acid bis(2-ethylhexyl ester) ammonium salt where the ammonium cation is derived from ammonia, dimethylaminoethanol, diethylaminoethanol, dimethylaminopropanol, 2-amino-2-methyl-1-propanol, methyldiethanolamine, 4-ethylmorpholine, 4-methylmorpholine, 4,4-dimethyloxazolidine.

12. The fibrous element according to claim 1 wherein the fibrous element 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.

13. The fibrous element according to claim 1 wherein the fibrous element comprises a filament.

14. The fibrous element according to claim 1 wherein the fibrous element exhibits an average diameter of less than 50 μm as measured according to the Average Diameter Test Method.

15. A fibrous structure comprising a plurality of fibrous elements according to claim 1 .

16. The fibrous structure according to claim 15 wherein the fibrous structure further comprises one or more solid additives.

17. The fibrous structure according to claim 16 wherein at least one of the solid additives comprises a naturally occurring fiber.

18. The fibrous structure according to claim 16 wherein the fibrous structure further comprises a scrim connected to the surface of the fibrous structure such that the solid additives are positioned between the scrim and a surface of a nonwoven substrate of the fibrous structure.

19. An aqueous hydroxyl polymer melt composition comprising a fibrous element-forming polymer and a dual purpose material that exhibits both a crosslinking facilitator function and a fast wetting surfactant function within the same dual purpose material, wherein the dual purpose material has the following Formula I:

wherein MOSS consists of M + and − O 3 S, where M + is an ammonium or iminium cation; and R 2 is independently selected from the group consisting of: alkyl, hydroxyalkyl, alkanolamine, aryl, hydroxylaryl, or part of a heterocyclic ring, and where R is a C 1 -C 18 linear or branched alkyl and/or a C 1 -C 12 linear or branched alkyl and/or a C 1 -C 8 linear or branched alkyl group.
