摘要： Absorbent wetlaid paper containing at least 1% by weight, calculated on the dry weight of the paper, of an absorbent polymeric material having a thermo-reversible liquid uptake capacity, which has a cloud point, Cp, in water within the temperature interval 30-60° C., preferably 35-55° C., at which the polymer has a substantially higher liquid uptake capacity at temperatures below said cloud point as compared to at temperatures above the cloud point. The thermo-reversible polymer will then be inactive during the papermaking process and be activated to its swelling and absorbent form when it is brought into contact with a liquid, the temperature of which is below the cloud point, Cp, of the polymer.

摘要： The present invention relates to an absorbent body 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 which, in use, is intended to face towards the wearer, and a second absorbent layer which is intended, in use, to face away from the wearer. According to the invention, the absorbent body includes at least two mutually different cellulose fluffs, wherein the major part of the fibre structure of the first absorbent layer is comprised of a first type of cellulose fluff having low liquid-spreading ability and a critical bulk which exceeds 8 cm.sup.3 /g at 2.5 kPa, while the major part of the fibre structure of the second absorbent layer is comprised of a different type of cellulose fluff having a critical bulk beneath 8 cm.sup.3 /g at 2.5 kPa and a higher liquid-spreading ability than the cellulose fluff in the first absorbent layer. The second absorbent layer will therefore be highly capable of draining liquid from the first absorbent layer. The second absorbent layer includes superabsorbent material which is admixed generally uniformly in the cellulose fluff within at least one area of the layer.

摘要： An absorbent porous structure for use in a diaper, a pant diaper, an incontinence guard, a sanitary napkin or the like, with a liquid acquisition portion and a liquid storage portion which are an integrated unit. The liquid acquisition portion comprises a compressed polymeric open-cell foam which expands upon wetting, and the liquid storage portion comprises a polymeric open-cell foam which may be the same or different from the foam in the liquid acquisition portion. The liquid storage portion also contains a superabsorbent material, with the amount of superabsorbent material being lower in the part of the liquid storage portion that is located closest to the liquid acquisition portion than in the part of the liquid storage portion that is located furthest from the liquid acquisition portion. Other embodiments include a method for producing the absorbent structure and an absorbent article containing such an absorbent structure.
