An incontinent pad has a pervious inner surface layer and impervious outer surface layer with both layers having edge portions connected together to form an envelope thereat. A high absorbent packet is contained within the formed envelope and overlies major areas of the impervious outer layer. A high loft porous webbed section is in initimate engagement with the high absorbent packet. The high absorbent packet has at least two juxtapositioned nonwoven webs of textile staple fibers with a layer of superabsorbent powder positioned between all of the adjacent webs. The edges of the webs are sealed together to prevent powder migration from the side. Each of the nonwoven webs of the high absorbent packet also includes a binder to impart sufficient strength to the nonwoven webs for facilitating handling and for allowing movement of the fiber under the expanding influence of the superabsorbent powder.
An incontinent pad comprising a liquid impervious layer defining the outer surface of the pad, a nonwoven staple fiber face layer defining the inner surface of the pad, and wherein said liquid impervious layer and said textile staple fiber face layer each includes edge portions with the edge portions of both layers connected together to form an envelope thereat having a pervious inner surface and impervious outer surface, a high absorbent packet contained within said formed envelope and overlying major areas of the impervious outer layer, and a high loft porous webbed section substantially filling the envelope with one surface of the porous section being in intimate engagement with said high absorbent packet and the opposing surface of the face layer, said high absorbent packet comprising at least two juxtapositioned nonwoven webs of textile staple fibers, a layer of superabsorbent non-thermoplastic polymer powder positioned between all of said adjacent layers of said nonwoven webs of textile staple fibers and wherein the average size of the superabsorbent powder particles are between 40 and 150 microns in diameter, and said nonwoven webs have a weight of 1.0 to 3 ounces per square yard, and are formed of staple fibers having a length of between 0.5" to 3.0" and a denier of about 1 to 5 so as to provide a Frazier permeability test equipment value reading of less than 244 feet per minute air flow at a 0.5 inch water gauge pressure drop so as to prevent superabsorbent powder, particularly the smaller particle sizes, from migrating through the juxtapositioned nonwoven webs, said webs having edge portions sealed together to prevent escapement of the superabsorbent powder from within, and each of said nonwoven webs of textile staple fibers having binder means thereon to impart sufficient strength to the nonwoven web for facilitating the handling thereof.
