  • Patent number: 6245962
    Abstract: Disclosed is an absorbent article, such as a disposable diaper, incontinent pad, sanitary napkin and the like that has as a component of the absorbent core a fluff cellulosic material. The absorbent core is especially effective and efficient for absorbing body fluids contacting the surface of the absorbent article. The absorbent core comprises a first absorbent layer having a fluff cellulosic material and a second absorbent layer of a resilient cellulosic material. The first absorbent layer can have an acquisition orifice so the second absorbent layer can quickly acquire any discharged body fluids. The absorbent article exhibits excellent wet crush recovery substantially without the use of polymeric or polyolefinic materials in either of the absorbent layers. The absorbent core when laterally crushed to approximately 40% of its initial dimension will recover to at least about 70% of its initial, precrushed dimension.
