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.

16. 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. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. 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. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
