Abstract
A method for manufacturing an absorbent structure in an absorbent article, such as a sanitary napkin, tampon, panty protector, incontinence guard, diaper, bed protector, wound or sore dressing, saliva absorbent and like articles is produced by using absorbent material in roll form directly in the product without first defibrating the material and then forming a mat. The material possesses good wicking properties and swelling properties, which are meaningful to the function of the product. A high surface dryness is obtained, among other things. In addition to cellulose fibres, the absorbent structure may also include superabsorbent material and/or binding fibres, among other ingredients, The pulp mat is very thin, therewith obviating the need to compress the mat further in the product. In the case of certain product applications, the material is softened mechanically prior to its use as an absorbent material.
