  • Patent number: 8388593
    Abstract: A fluid-management article, such as a sanitary napkin, comprises a body-faceable, liquid-pervious cover having a top surface, a garment-faceable, liquid-impervious barrier, and an absorbent system intermediate the cover and the barrier. The fluid-management article comprises a plurality of fluid-guiding channels that surround a plurality of isolated protrusions. The channels and the protrusions are formed through the top surface of the cover of the fluid management article. The protrusions have an apex that extends a height greater than about 0.5 millimeters (mm) above at least a portion of the plurality of channels. The protrusions have a number density greater than about 0.15 protrusions/cm2.
