Abstract

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

First claim

What is claimed is:

1 . An absorbent fibrous structure comprising a soil adsorbing agent and a detackifier.

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 the absorbent fibrous structure exhibits an average Mirror Cleaning Densitometer Value of greater than −0.45 as measured according to the Mirror Cleaning Test Method.

6 . The absorbent fibrous structure according to claim 1 wherein soil adsorbing agent comprises a branched copolymer.

7 . The absorbent fibrous structure according to claim 6 wherein the branched copolymer comprises a monomeric unit derived from an acrylamide compound.

8 . The absorbent fibrous structure according to claim 6 wherein the branched copolymer comprises a monomeric unit derived from a methylene bisacrylamide compound.

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

10 . The absorbent fibrous structure according to claim 1 wherein the soil adsorbing agent and the detackifier are present in an emulsion.

11 . The absorbent fibrous structure according to claim 10 wherein the emulsion is an inverse emulsion.

12 . The absorbent fibrous structure according to claim 11 wherein the emulsion is a dewatered inverse emulsion.

13 . The absorbent fibrous structure according to claim 10 wherein the emulsion comprises less than 37% by weight of the soil adsorbing agent.

14 . The absorbent fibrous structure according to claim 10 wherein the emulsion comprises greater than 0.1% by weight of the detackifier.

15 . The absorbent fibrous structure according to claim 10 wherein the emulsion further comprises a hydrocarbon fluid.

16 . The absorbent fibrous structure according to claim 10 wherein the emulsion comprises a viscosity of less than 2000 cps as measured according to the Bulk Viscosity Test Method.

17 . A multi-ply sanitary tissue product comprising an absorbent fibrous structure according to claim 1 .

18 . A method for making an absorbent fibrous structure according to claim 1 wherein the method comprises the step of contacting an absorbent fibrous structure with an emulsion comprising a soil adsorbing agent and a detackifier.

19 . An absorbent fibrous structure comprising an emulsion comprising a soil adsorbing agent comprising a monomeric unit derived from acrylamide compound and a monomeric unit derived from a hydroxyalkylacrylate compound and a detackifier.

20 . An absorbent fibrous structure comprising an emulsion comprising a soil adsorbing agent comprising polyacrylamide and a detackifier.
