ABSTRACT:
A method of producing an absorbent structure in an absorbent article includes the steps of compressing an air laid web of cellulose fibers into a dry-formed sheet having a first density of between 0.2-1.0 g/cm.sup.2 and mechanically softening the compressed sheet by a noncutting method to a second density, which is lower than the first density, whereby the sheet is delaminated so as to form a plurality of partially separated thin fiber layers, each of which layers exhibits a density which corresponds to the first density.
