  • Absorbent article having a hydrophobic transport layer
    Patent number: 4798603
    Abstract: A distinctive absorbent article includes an absorbent body composed of a substantially hydrophilic material which is capable of absorbing a selected liquid. A liquid permeable topsheet layer composed of a substantially hydrophobic material is superposed in facing relation with said absorbent body and has an effective average pore size therein. A liquid permeable transport layer is located between the topsheet layer and the absorbent body, and is composed of a material which is less hydrophilic than the absorbent body and has an effective average pore size therein which is smaller than the pore size of the topsheet layer.
