PROBLEM TO BE SOLVED: To obtain an absorbing material excellent in various kinds of absorbing characteristics such as absorbing rate or absorbing magnification under pressure and shape-retaining property and provide a method for inexpensively producing the absorbing material by simplifying a production process to improve productivity. SOLUTION: Water content of a water-containing gel of a hydrophilic crosslinking polymer is reduced while pressurizing (rolling). A water-containing gel composition 10 comprising, e.g. a water-containing gel containing a crosslinked poly(meth)acrylic acid (salt), a glycerol (e.g. a polyhydric alcohol), a polyester fiber (e.g. a forming auxiliary material), etc., is fed onto the upstream side of a pressure roller 2 in a drier drum 1. The water-containing gel composition 10 is pressurized (rolled) and heated by a pressure roller 2 to form a sheet 11. Thereby, the objective sheet-like absorbing material whose at least one side is smooth is obtained. |
