Abstract

1503207 Laminated absorbent sheet material UNION CARBIDE CORP 23 May 1975 [18 June 1974] 22481/75 Heading B5N A disposable absorbent article, e.g. a disposable diaper or incontinence pad comprises a hydrophobic liquid-permeable top sheet and a liquid impermeable back sheet having therebetween a hydrophilic water-insoluble film containing slits of length 1/16-# inch, preferably #-5/16 inch, whereby liquid contacting the film causes it to swell and the slits to open to permit passage of liquid therethrough. The film may be polyvinyl pyrrolidone, polyacrylic acid and/or irradiated polyethylene oxide, of thickness 0À5-2À0 mils. The top sheet may be an open cell foam, woven or non-woven fibrous material, gauze, or slitted ethylene-ethyl acrylate copolymer film. The back sheet may be olefinic or vinyl material, e.g. embossed polyethylene of thickness 0À4-1À5 mils. Further absorbent layers of cellulosic tissue, non-woven wood fluff or polymeric material may be present on one or both sides of the film. The top and back sheets may be heat- or adhesive-sealed together so as to enclose the slit film.
