-20- ABSTRACT OF THE DISCLOSURE An absorbent structure comprising a low density cellulosic core formed from a blend of 70-97% by weight of cellulosic fibres and 3-30% by weight of polyethylene pulp, based on the total weight of the cellulosic fibres and polyethylene pulp, is disclosed. The polyethylene pulp is formed from polyethylene having a density in the range of 0.930-0.965 g/cm3 and a melt index of less than 8 dg/min. The polyethylene pulp has monocomponent fibres and the core has a matrix of bonded polyethylene pulp. The blend may contain super absorbent polymer. Absorbent structures of improved properties are obtained e.g. for use in diapers and other absorbent structures. - 20 -
