Hydroxyl polymer web structures comprising a tuft
Web structures comprising a tuft and methods for making same are provided. More particularly, web structures comprising a polymeric structure comprising a crosslinked, hydroxyl polymer, wherein the web structure comprises a tuft and processes for making such web structures are provided.
1. A sanitary tissue product comprising a web structure comprising a tuft that defines an open void area tunnel, wherein the web structure comprises a first fiber comprising a crosslinked, hydroxyl polymer selected from the group consisting of starch, starch derivatives and mixtures thereof and wherein the tuft comprises the first fiber and wherein the web structure further comprises a second fiber having a chemically different composition relative to the first fiber comprising the crosslinked, hydroxyl polymer wherein the sanitary tissue product further comprises an additional ply of a web structure such that the tuft protrudes at least into the additional ply.
2. The sanitary tissue product according to claim 1 wherein the tuft protrudes through the additional ply.
3. The sanitary tissue product according to claim 1 wherein the polymeric structure further comprises a hydroxyl polymer selected from the group consisting of: polyvinyl alcohol, polyvinyl alcohol derivatives, chitosan, chitosan derivatives, cellulose derivatives, gums, arabinans, galactans, proteins, and mixtures thereof.
4. The sanitary tissue product according to claim 1 wherein the web structure comprises a plurality of tufts.
5. The sanitary tissue product according to claim 4 wherein the plurality of tufts are uniformly distributed on the web structure.
6. The sanitary tissue product according to claim 1 wherein the web structure comprises a plurality of substantially randomly oriented first fibers.
7. The sanitary tissue product according to claim 1 wherein the first fiber has a fiber diameter of less than about 50 μm.
8. The sanitary tissue product according to claim 1 wherein at least a portion of the first fiber exhibits no melting point.
9. The sanitary tissue product according to claim 1 wherein the tuft is integral with, but extends from the web structure.
10. A sanitary tissue product comprising a layered web structure comprising a first layer and a second layer, wherein the first layer comprises a first composition and the second layer comprises a second composition, wherein the first and second compositions are chemically different such that the first layer exhibits an extensibility different from the second layer, wherein a portion of one layer protrudes at least into the other layer such that a surface of the layered web structure comprises a tuft that defines an open void area tunnel, wherein the layered web structure comprises a polymeric structure comprising a crosslinked, hydroxyl polymer selected from the group consisting of starch, starch derivatives and mixtures thereof and wherein the tuft comprises the crosslinked, hydroxyl polymer.
11. The sanitary tissue product according to claim 10 wherein the first composition comprises the polymeric structure.
12. The sanitary tissue product according to claim 10 wherein the polymeric structure further comprises a hydroxyl polymer selected from the group consisting of: polyvinyl alcohol, polyvinyl alcohol derivatives, chitosan, chitosan derivatives, cellulose derivatives, gums, arabinans, galactans, proteins, and mixtures thereof.
13. The sanitary tissue product according to claim 10 wherein the layered web structure comprises a plurality of tufts.
14. The sanitary tissue product according to claim 13 wherein the plurality of tufts are uniformly distributed on the layered web structure.
15. The sanitary tissue product according to claim 10 wherein the layered web structure comprises a nonwoven web comprising substantially randomly oriented fibers.
16. The sanitary tissue product according to claim 10 wherein the fiber has a fiber diameter of less than about 50 μm.
17. The sanitary tissue product according to claim 10 wherein at least a portion of the fiber exhibits no melting point.
18. The sanitary tissue product according to claim 10 wherein the polymeric structure is in the form of a film.
19. The sanitary tissue product according to claim 10 wherein the tuft is integral with, but extends from the layered web structure.
20. The sanitary tissue product according to claim 10 wherein the sanitary tissue product further comprises an additional ply of a web structure such that the tuft protrudes at least into the additional ply.
21. The sanitary tissue product according to claim 20 wherein the tuft protrudes through the additional ply.
