Abstract
An elastic absorbent assembly is presented for use in manufacturing disposable absorbent garments. The elastic assembly includes an absorbent core comprising: a base layer having a pair of side edges and a longitudinal centerline spaced inwardly from the side edges; an elastic construction supported by the base layer, the elastic construction including a plurality of spaced apart elastic elements forming a plurality of channels and a plurality of cells; and superabsorbent polymer particles coupled to the elastic elements.
Claims26
A disposable absorbent article having an elastic absorbent assembly, said article comprising:
- a chassis;
- and
- an absorbent core supported by the chassis, comprising:
- a base nonwoven layer having a pair of side edges and a longitudinal centerline spaced inwardly from the side edges;
- an elastic construction supported by the base layer, the elastic construction including a plurality of spaced apart elastic elements forming a plurality of channels and a plurality of cells;
- and
- superabsorbent polymer particles coupled to cells created by the elastic elements and;
- and a top nonwoven layer disposed over the base layer and the elastic construction, wherein the elastic elements are adhered to both the base layer and the top layer forming said cells defined between pairs of the elastics and the top and base layers, and wherein superabsorbent particles are coupled in said cells.

A method of making an elastic composite for incorporation into a disposable absorbent garment, said method comprising the steps of:
- conveying a first sheet of material;
- spinning a section of a continuous strand of elastic element on the first sheet on the platform, thereby applying the section of elastic element onto the first sheet along a direction generally transverse to a moving first sheet;
- cutting the section of elastic element to sever the section from the continuous strand;
- and
- repeating the spinning and cutting steps such that a plurality of spaced apart elastic elements are applied on the first sheet;
- applying a second sheet of material onto the first sheet having a plurality of elastic elements applied thereon, thereby providing a web of elastic composite having at least two sheets of material and a plurality of elastic elements sandwiched therebetween, wherein said elastic elements are adhered to each of the first sheet and the second sheet such that a plurality of cells are formed between the elastics and the first and second sheets, and wherein prior to forming said cells, superabsorbent particles are applied between the first and second sheets, such that said elastic composite includes cells of superabsorbent particles defined between pairs of elastic elements adhered to the first and second sheets and between said first and second sheets.
