Abstract

Absorbent fibrous structures containing a branched copolymer soil adsorbing agent and methods for making same are provided.

First claim

What is claimed is:

1 . An absorbent fibrous structure comprising a branched copolymer soil adsorbing agent such that the absorbent fibrous structure exhibits a CRT Initial Rate that is greater than the CRT Initial Rate of the absorbent fibrous structure void of soil adsorbing agents as measured according to the CRT Test Method.

2 . The absorbent fibrous structure according to claim 1 wherein the absorbent fibrous structure exhibits an average Soil Adsorption Value of about 90 mg soil/g absorbent fibrous structure or greater as measured according to the Soil Adsorption Test Method.

3 . The absorbent fibrous structure according to claim 1 wherein the absorbent fibrous structure comprises a plurality of pulp fibers.

4 . The absorbent fibrous structure according to claim 1 wherein the absorbent fibrous structure exhibits a moisture level of less than 30% as measured according to the Moisture Content Test Method.

5 . The absorbent fibrous structure according to claim 1 wherein branched copolymer soil adsorbing agent comprises a monomeric unit derived from an acrylamide compound.

6 . The absorbent fibrous structure according to claim 1 wherein the branched copolymer soil adsorbing agent is present in the absorbent fibrous structure at a level of from about 0.005% to about 5% by weight of the absorbent fibrous structure.

7 . The absorbent fibrous structure according to claim 1 wherein the absorbent fibrous structure further comprises a surfactant.

8 . The absorbent fibrous structure according to claim 1 wherein the absorbent fibrous structure exhibits a CRT Initial Rate of greater than 0.54 g/second as measured according to the CRT Test Method.

9 . A single- or multi-ply sanitary tissue product comprising the absorbent fibrous structure according to claim 1 .

10 . The sanitary tissue product according to claim 10 wherein the sanitary tissue product comprises a paper towel.

11 . A cleaning pad comprising the absorbent fibrous structure according to claim 1 .

12 . An absorbent fibrous structure comprising a branched copolymer soil adsorbing agent such that the absorbent fibrous structure exhibits a CRT Initial Rate that is greater than 0.54 g/second as measured according to the CRT Test Method.

13 . The absorbent fibrous structure according to claim 12 wherein the absorbent fibrous structure comprises a plurality of pulp fibers.

14 . The absorbent fibrous structure according to claim 12 wherein the absorbent fibrous structure exhibits a moisture level of less than 30% as measured according to the Moisture Content Test Method.

15 . The absorbent fibrous structure according to claim 12 wherein branched copolymer soil adsorbing agent comprises a monomeric unit derived from an acrylamide compound.

16 . The absorbent fibrous structure according to claim 12 wherein the branched copolymer soil adsorbing agent is present in the absorbent fibrous structure at a level of from about 0.005% to about 5% by weight of the absorbent fibrous structure.

17 . The absorbent fibrous structure according to claim 12 wherein the absorbent fibrous structure further comprises a surfactant.

18 . A single- or multi-ply sanitary tissue product comprising the absorbent fibrous structure according to claim 12 .

19 . The sanitary tissue product according to claim 18 wherein the sanitary tissue product comprises a paper towel.

20 . A cleaning pad comprising the absorbent fibrous structure according to claim 12 .
