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.
Claims20
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.
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.
