초록 ▼

A technique for incorporating odor control agent particles into an absorbent article is provided. More specifically, the odor control particles are “homogenously” distributed (e.g., in a substantially uniform manner) within an airformed fiber matrix of an absorbent core of an absorbent article. An absorbent core containing such a homogeneously distributed odor control particles may possess a greater surface area for contacting malodorous compounds, thereby increasing the likelihood of odor reduction.

What is claimed is: 1. A method for forming an absorbent web with odor control properties, the method comprising: treating a fibrous sheet with a coating formulation that comprises odor control particles; fiberizing the treated sheet to form a plurality of individual fibers; entraining the fibers in a gaseous stream; and thereafter, depositing the fibers onto a forming surface to form a web comprising odor control particles, wherein substantially all of the odor control particles in the web originate from the treated sheet. 2. The method of claim 1, wherein the odor control particles are inorganic oxide particles. 3. The method of claim 2, wherein the inorganic oxide particles contain silica, alumina, or both. 4. The method of claim 3, wherein the inorganic oxide particles are modified with a transition metal. 5. The method of claim 1, wherein the odor control particles contain a quinone compound. 6. The method of claim 1, wherein the odor control particles constitute from about 0.01 to about 20 wt. % of the coating formulation. 7. The method of claim 1, wherein a solvent constitutes from about 40 to about 99 wt. % of the coating formulation. 8. The method of claim 1, wherein the odor control particles are homogeneously distributed within the web. 9. The method of claim 1, wherein the odor control particles are present in an amount of from about 0.1 to about 10 wt. % of the web. 10. The method of claim 1, wherein the fibrous sheet is a fluff pulp sheet. 11. A method for forming an absorbent web with odor control properties, the method comprising: treating a superabsorbent material with a coating formulation, the coating formulation comprising odor control particles; fiberizing a fibrous sheet to form a plurality of individual fibers; entraining the fibers in a gaseous stream; intermixing substantially all of the treated superabsorbent material with the entrained fibers; and thereafter, depositing the fibers and the treated superabsorbent material onto a forming surface to form a web comprising odor control particles, wherein substantially all of the odor control particles in the web originate from the treated superabsorbent material. 12. The method of claim 11, wherein the odor control particles are inorganic oxide particles. 13. The method of claim 12, wherein the inorganic oxide particles contain silica, alumina, or both. 14. The method of claim 13, wherein the inorganic oxide particles are modified with a transition metal. 15. The method of claim 11, wherein the odor control particles contain a quinone compound. 16. The method of claim 11, wherein the odor control particles constitute from about 0.01 to about 20 wt. % of the coating formulation. 17. The method of claim 11, wherein a solvent constitutes from about 40 to about 99 wt. % of the coating formulation. 18. The method of claim 1, wherein the odor control particles are homogeneously distributed within the web. 19. The method of claim 11, wherein the odor control particles are present in an amount of from about 0.1 to about 10 wt. % of the web. 20. The method of claim 11, wherein the fibrous sheet is a fluff pulp sheet.
