Definitions
- Absorbent articles of the above mentioned kind are intended to be used for absorption of body liquids such as urine and blood. They usually comprise a liquid pervious topsheet, which during use is intended to be facing the wearer's body, e g a nonwoven material of spunbond type, a meltblown material, a carded bonded wadding etc. They further have a liquid impervious backsheet, e g a plastic film, a plastic coated nonwoven or a hydrophobic nonwoven, and an absorbent structure arranged between the liquid pervious topsheet material and the liquid impervious backsheet. This absorbent structure may be constructed by several layers such as a liquid acquisition layer, storage layer and distribution layer.
- Fig. 1 shows a schematic cross section of an absorbent structure according to the invention in compressed form containing three different integrated layers
- Fig. 2 shows the absorbent structure according to Fig. 1 in expanded form.
- Fig. 3 shows in a view from above an absorbent article in the form of an incontinence guard.
- the superabsorbent material may also be applied on the dried foam, e g in the form of a monomer solution which is applied on the side of the which is intended to be facing away from the wearer.
- the monomer solution will then form a coating on one side of the foam and a part of the monomer solution will penetrate into the open pore system of the foam.
- the monomer solution is polymerized and is then crosslinked. With this method there is provided a gradient of the superabsorbent concentration from one side of the foam on which the monomer solution has been applied and a distance into the foam material, so far as the monomer solution has penetrated.
- the topsheet 6 and the backsheet 7 have a somewhat larger extension in the plane than the absorbent structure 1 and extend outside the edges thereof.
- the layers 6 and 7 are interconnected within their projecting portions, e g by gluing or welding with heat or ultrasonic.
