1. An odor control substrate having a plane of orientation defined by the cross machine direction and machine direction of the substrate, the substrate comprising a plurality of fibers oriented from about 30°
- to about 150°
relative to an axis that is perpendicular to the plane of orientation, at least a portion of said fibers being exposed on a surface of the substrate, wherein an odor control coating is applied to the substrate so that a majority of said coating resides on said exposed fibers, said odor control coating comprising an odor adsorbent that is capable of adsorbing one or more odorous compounds when contacted therewith.

Abstract
An odor control substrate that contains a plurality of fibers oriented in the z-direction is provided. At least some of the fibers contain portions that are exposed on an outer surface of the substrate. An odor control coating is applied to the substrate so that a majority of the coating resides on the exposed portions. As a result, the odor control substrate may retain certain of its beneficial properties even after being applied with the odor control coating, such as good extensibility, absorbency, etc.
