  • Sanitary napkin pad liner
    Patent number: 4795455
    Abstract: A napkin pad liner is provided which is designed to be used with a conventional sanitary napkin to provide more rapid fluid take-up and reduced fluid strikeback. The liner includes a cover of a non-wettable, fluid permeable hydrophobic material which covers a thin layer of absorbent fabric. Pressure sensitive adhesive is located on the napkin-facing side of the absorbent fabric. The adhesive is protected prior to use of the liner by a release strip. In a preferred embodiment the liner is embossed with a central channel to promote rapid longitudinal fluid distribution at the time of fluid take-up.
