Absorbent article

An absorbent article comprises an absorbent body of a hydrophilic material having a liquid permeable top cover which has an effective average pore size. A liquid permeable transport layer is located between the top cover and absorbent body. This is made of a material which is less hydrophilic than t...

Beschreibung
Zusammenfassung:	An absorbent article comprises an absorbent body of a hydrophilic material having a liquid permeable top cover which has an effective average pore size. A liquid permeable transport layer is located between the top cover and absorbent body. This is made of a material which is less hydrophilic than the absorbent body and has an effective pore size smaller than the topcover pore size. Pref. the absorbent body includes an absorbent hydrogel polymer material. A distinctive absorbent article includes an absorbent body (16) composed of a substantially hydrophilic material which is capable of absorbing a selected liquid. A liquid permeable topsheet layer (14) 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 (18) is located between the topsheet layer (14) and the absorbent body (16), and is composed of a material which is less hydrophilic than the absorbent body (16) and has a pore size gradient through a thickness dimension of the transport layer (18).
