  • Patent number: 4392862
    Abstract: Absorptive devices comprising a facing element, a support element, an absorbent core, and a backsheet. The facing element is a body fluid permeable, unbonded, carded web of resilient, hydrophobic fibers which has been affixed to the supporting element through the means of spaced apart regions of bonding. The supporting element is a body fluid permeable planer sheet compatible with and affixed to the facing element. The absorbent core must absorb and retain body fluids while the backsheet must be impermeable to such fluids. The four elements are superimposed one upon another in the order mentioned and are united in that position to form devices such as disposable diapers, sanitary napkins, incontinent pads and the like.
