Abstract
The invention concerns a porous material, a method for making same and its applications. Said porous material comprises a mixture of cellulose fibres and at least an elastomer and is characterised in that it has a honeycomb structure having cells with a size ranging between 0.1 and 10 mm, a density of the order of 0.03 to 0.1, water absorbing capacity not less than 750%, and water holding capacity after manual wringing less than 100%. The invention is applicable for making in particular sponges and household goods comprising a spongy element such as brushes and squeegees for cleaning surfaces.
