A method for manufacturing a structurally integral, compound fluid-absorbent structure having superposed transfer and reservoir layers united in an intimate fluid-communicative relationship. The method comprises the steps of laying in a superposed relationship and in physical contact a slurry of cellulosic fibrous material forming the transfer layer and a slurry of peat moss material forming the reservoir layer. The resulting laminated composite slurry layer is dewatered and calendered to enhance the drying power of the reservoir layer. Subsequently, the laminated composite web is subjected to perf-embossing to relax the fibrous network of the transfer layer and enhance its ability to rapidly take-up fluid. To render the transfer layer responsive to the perf-embossing operation, a debonding agent is incorporated therein. The invention also extends to a fluid-absorbent component manufactured by the aforementioned method, which can be used as an absorbent core for disposable absorbent products such as sanitary napkins, diapers, urinary pads, adult briefs, wound dressings, and the like.
