Absorbent articles with improved odor control
First Claim
1. An absorbent article having odor control properties, the article comprising an absorbent core that includes an airformed web, the airformed web containing a matrix of fluff pulp fibers in which odor control particles are homogeneously distributed throughout the matrix by binding along lengths of fibers used to form the matrix prior to formation of the matrix, wherein the binding is accomplished without the use of chemical binders or other attachment structures, wherein the pulp fibers are separated via fiberizing after odor control particle binding and the separated fibers then form the matrix, wherein the odor control particles are inorganic oxide particles, wherein the inorganic oxide particles have an average particle size of from about 1 nanometer to about 50 nanometers.

Abstract
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.
