PCT No. PCT/JP96/03191 Sec. 371 Date Jun. 26, 1997 Sec. 102(e) Date Jun. 26, 1997 PCT Filed Oct. 31, 1996 PCT Pub. No. WO97/16492 PCT Pub. Date May 9, 1997A water content of a water-containing gel of a hydrophilic cross-linked polymer is reduced by pressuring (calendaring) it. Then, a gel composition including, for example, a water-containing gel including cross-linked poly(meth)acrylic acid (salt), glycerol (polyhydric alcohol) and polyester fibers (auxiliary forming material), etc., is fed to a drum dryer on an upstream side of a pressurizing roller. Then, the resulting gel composition is pressurized (calendared) heated by a pressurizing roller to be formed into a sheet. As a result, a sheet-like absorbent material having at least one smooth surface can be obtained. The absorbent material resulting from the described method shows excellent properties and especially absorbing properties such as absorbing rate, absorbency under load, and shape retaining properties. |
