ABSTRACT:
A method for making an absorbent member is disclosed. The method includes introducing fibers into an air stream to form an air-fiber mixture. This air-fiber mixture is then directed to a porous media having a first surface. The air-fiber mixture contacts the first surface and the fibers collect on the first surface and forms a fibrous mat. The air passes through the first surface and can be recovered and recycled, if desired. The air-fiber mixture is then terminated or diverted so that the fibrous mat can be removed from the first surface. The fibrous mat is wetted by water to obtain a desired moisture content. Finally, the wetted fibrous mat is compressed to a predetermined thickness to form an absorbent member, which has unique expansion properties.
