Absorbent body for an absorbent article

A diaper, comprising:

• a casing;
• an absorbent body enclosed in the casing,
• a back part which is intended to be placed rearwardly on a wearer in use,
• a front part which is intended to be placed forwardly on the wearer in use, and
• a crotch part which extends between the back part and the front part and which is intended to be placed in the crotch region of the wearer in use, between the thighs thereof, as seen from a side of the diaper proximal to the wearer in use,
• the absorbent body includes a first fibre-based absorbent layer of fluff-pulp and a second fibre-based absorbent layer of superabsorbent material and fibre-based fluff-pulp material, which second absorbent layer exhibits a high liquid-dispersing ability,
• the first absorbent layer includes a superabsorbent material of high gel strength mixed essentially uniformly in the fibre material within at least one area of the layer, said first absorbent layer containing between 2 and 30% superabsorbent material calculated on the total dry weight of the layer in the at least one area in which the superabsorbent is mixed, and
• the second absorbent layer includes at least one layer of superabsorbent material within at least one area of the second layer, the second absorbent layer containing between 2 and 60% superabsorbent material calculated on the total dry weight of the layer in the at least one area in which the superabsorbent material is distributed, and,
• wherein the at least one layer of superabsorbent material of the second absorbent layer is substantially not mixed with the fibre-based material of the second absorbent layer.

An absorbent body comprising:

• a first fibre-based absorbent layer which is intended to lie proximal to a wearer in use,
• a second fibre-based absorbent layer which is intended to lie distal to the wearer in use,
• the second absorbent layer exhibiting a high liquid-dispersing ability,
• the first absorbent layer includes a superabsorbent material of high gel-strength which is admixed essentially uniformly in fibre material of the first absorbent layer within a least one area of the first absorbent layer, and
• the second absorbent layer includes upper and lower fibre layers and at least one layer of superabsorbent material disposed between the upper and lower fibre layers;
• wherein a major part of the fibre material in the first absorbent layer includes a fluff-pulp having an open fibre structure and a critical bulk above 8 cm.sup.3 /g at 2.5 kPa;
• and fibre material in at least the upper fibre layer of said second absorbent layer lying proximal to the first absorbent layer includes mainly another type of fluff-pulp having a critical bulk beneath 8 cm.sup.3 /g at 2.5 kPa and has a higher liquid-dispersing ability than the fluff-pulp in the first absorbent layer.
