The invention addresses problems with liquid absorbent pads having at least about 50% of their absorption capacity represented by water absorbent (including water-swellable) material capable of absorbing at least about 5 times its own dry weight of aqueous liquid. By openings of specified area, present in undulating layer(s) of such absorbent material in specified numbers and total area per unit area of said layer(s), and/or through forming such openings as hinges and displaced flap members for locking the layers of a moving composite together for bending into said undulating configuration, and/or through use of sheath members of material which substantially retain their structural integrity in contact with aqueous liquids, and have open or openable portion(s), pads are formed with both high absorption rate and capacity and/or ready disposability and/or rapid production characteristics, ideally suited for urinary incontinence care and other uses.

A method for producing an absorbent pad, said method comprising the steps of making a plurality of cuts in an absorptive layer including a water-swellable material, each of said cuts forming a flap member which is attached to the absorptive layer by a hinge member, but is otherwise severed therefrom

A method for producing an absorbent pad, said method comprising the steps of making a plurality of cuts in an absorptive layer including a water-swellable material, each of said cuts forming a flap member which is attached to the absorptive layer by a hinge member, but is otherwise severed therefrom, and pushing the flap members away from the adjacent cuts, leaving openings with the flap members extending away therefrom.
