Abstract

Fibrous structures containing filaments and solid additives, and more particularly to fibrous structures containing filaments and solid additives wherein the fibrous structure has three or more regions that exhibit different characteristics and/or properties and methods for making same, are provided.

First claim

What is claimed is:

1. A wipe comprising a plurality of filaments and a plurality of solid additives, the wipe further comprising a pattern comprising two or more different regions that exhibit different basis weights, wherein the plurality of filaments are present in the wipe at a level of less than 90% by weight of the wipe on a dry basis;
wherein the wipe is a core component;
wherein the wipe further comprises a scrim component.

2. The wipe according to claim 1 wherein the one of the two or more different regions is dispersed throughout another of the two or more different regions.

3. The wipe according to claim 1 wherein the plurality of filaments are present in the wipe at a level of less than 80% by weight of the wipe on a dry basis.

4. The wipe according to claim 1 wherein the plurality of solid additives are present in the wipe at a level of greater than 10% by weight of the wipe on a dry basis.

5. Wipe according to claim 1 wherein the plurality of filaments and the plurality of solid additives are present in the wipe at a weight ratio of filaments to solid additives of greater than 0 but less than 1.

6. The wipe according to claim 1 wherein the plurality of filaments and the plurality of solid additives are commingled together.

7. The wipe according to claim 1 wherein at least one of the plurality of filaments comprises a thermoplastic polymer.

8. The wipe according to claim 7 wherein the thermoplastic polymer is selected from the group consisting of: polyolefins, polyesters, polyhydroxyalkanoates, polyhydroxybutyrates, and mixtures thereof.

9. The wipe according to claim 7 wherein the thermoplastic polymer is a biodegradable thermoplastic polymer.

10. The wipe according to claim 7 wherein the thermoplastic polymer is a compostable thermoplastic polymer.

11. The wipe according to claim 7 wherein the thermoplastic polymer is selected from the group consisting of: polylactic acid, polyhydroxyalkanoate, polycaprolactone and mixtures thereof.

12. The wipe according to claim 1 wherein the plurality of solid additives comprise fibers.

13. The wipe according to claim 1 wherein the scrim component comprises greater than 99% by weight of filaments.

14. The wipe according to claim 1 wherein the pattern comprises a continuous network and a plurality of discrete zones.

15. The wipe according to claim 1 wherein the wipe comprises a liquid composition.

16. The wipe according to claim 15 wherein the wipe is a wet wipe.

17. The wipe according to claim 1 wherein the wipe is a baby wipe.

18. A stack of wipes comprising a plurality of wipes according to claim 1 .
