摘要:
A method for producing an absorbent structure intended for use in an absorbent article, such as a sanitary napkin, incontinence guard, diaper, wherein the absorbent structure in produced by laying a layer of essentially superabsorbent material between two layers of defibered and moisturized cellulose pulp or tissue, whereafter the composite structure is calendared between one or more pairs of heated rolls, wherewith the layer of superabsorbent material binds in itself and forms a stable layer, which binds to the surrounding cellulose pulp layers or tissue layers. The absorbent structure exhibits excellent absorption properties and can be made very thin. The structure can be manufactured without superabsorbent material being spread around the manufacturing machine during the production process, or escaping from the finished absorbent article when packaging, transporting or using the article.
