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.
Claims35
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.
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 sheet to form a plurality of individual fibers;
- entraining the fibers in a gaseous stream;
- and
- thereafter, depositing the fibers onto a forming surface.
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 the treated superabsorbent material with the entrained fibers;
- and
- thereafter, depositing the fibers and the treated superabsorbent material onto a forming surface.
