Abstract

Pre-moistened fibrous structures containing filaments and solid additives, wherein the fibrous structures exhibit capacity values that are superior to known pre-moistened fibrous structures as measured according to the Capacity Test Method described herein and methods for making same are provided.

First claim

What is claimed is:

1. A pre-moistened, calendered, co-formed fibrous structure comprising a plurality of filaments, and a plurality of solid additives commingled together, wherein the pre-moistened, calendered, co-formed fibrous structure further comprises a scrubby component comprising a surface pattern on the pre-moistened, calendered, co-formed fibrous structure that provides aggressive cleaning by the pre-moistened, calendered, co-formed fibrous structure during use and wherein the pre-moistened, calendered, co-formed fibrous structure further comprises a liquid composition such that the pre-moistened, calendered, co-formed fibrous structure exhibits a capacity value of at least 8.5 g of liquid composition/g of dried fibrous structure as measured according to the Capacity Test Method, wherein the pre-moistened, calendered, co-formed fibrous structure exhibits a basis weight of from about 125 g/m 2 to about 800 g/m 2 as measured according to the Fibrous Structure Basis Weight Test Method and wherein the pre-moistened, calendared, co-formed fibrous structure comprises a core component a co-formed fibrous structure that exhibits a basis weight of greater than 50% to less than 100% of the total basis weight of the pre-formed, calendered, co-formed fibrous structure as measured according to the Fibrous Structure Basis Weight Test Method.

2. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the plurality of filaments are present in the pre-moistened, calendered, co-formed fibrous structure at a level of less than 90% by weight of the pre-moistened, calendered, co-formed fibrous structure on a dry basis.

3. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the plurality of solid additives are present in the pre-moistened, calendered, co-formed fibrous structure at a level of greater than 10% by weight of the pre-moistened, calendered, co-formed fibrous structure on a dry basis.

4. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the plurality of filaments and the plurality of solid additives are present in the pre-moistened, calendered, co-formed fibrous structure at a weight ratio of the plurality of filaments to the plurality of solid additives of greater than 0 but less than 1 .

5. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein at least one of the plurality of filaments comprises a thermoplastic polymer.

6. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the plurality of solid additives comprise fibers.

7. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the pre-moistened, calendered, co-formed fibrous structure further comprises a first region and a second region, wherein the first and second regions exhibit at least one common micro-CT intensive property that differs in value as measured according to the Micro-CT Test Method.

8. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the pre-moistened, calendered, co-formed fibrous structure is a floor cleaning pad.

9. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the liquid composition comprises a surfactant.

10. The pre-moistened, calendered, co-formed fibrous structure according to claim 1 wherein the scrubby component comprises a filament that exhibits a greater average fiber diameter than the average fiber diameter of the plurality of filaments commingled with the plurality of solid additives.
