Abstract
A tampon is provided with a permeable or soluble barrier layer interposed between an absorbent core and an overwrap, allowing substantially complete, uniform wetting to be obtained even under light flow conditions. The barrier prevents immediate flow of fluid into the core, allowing time for fluid to be carried by the overwrap around the outer surface of the tampon, prior to being drawn into the absorbent core.
