Patent

CA 2117342

The present invention relates to an absorbent body (3) which is intended to form the absorbent element in an absorbent article, such as a diaper, an incontinence guard or a sanitary napkin, and includes a first absorbent layer (16) which, in use, is intended to face towards the wearer, and a second absorbent layer (17) which is intended, in use, to face away from the wearer. According to the invention, the absorbent body (3) includes at least two mutually different cellulose fluffs, wherein the major part of the fibre structure of the first absorbent layer (16) is comprised of a first type of cellulose fluff having low liquid-spreading ability and a critical bulk which exceeds 8 cm3/g at 2.5 kPa, while the major part of the fibre structure of the second absorbent layer (17) is comprised of a different type of cellulose fluff having a critical bulk beneath 8 cm3/g at 2.5 kPa and a higher liquid-spreading ability than the cellulose fluff in the first absorbent layer (16). The second absorbent layer (17) will therefore be highly capable of draining liquid from the first absorbent layer (16). The second absorbent layer (17) includes superabsorbent material which is admixed generally uniformly in the cellulose fluff within at least one area of the layer (17).
