Claims
- 1. A method for the production of an absorbent material comprising spreading 100 parts by weight of absorbent resin particles in the form of a planar layer having a thickness regulated in the approximate range of about 0.3 to 5 mm on a substrate and bringing 15 to 150 parts by weight of water and/or steam into contact with said planar layer without disturbing the constitution of said planar layer.
- 2. A method for the production of an absorbent material comprising spreading 100 parts by weight of absorbent resin particles and 0.1 to 10 parts by weight of at least one absorption auxiliary selected from the group consisting of water-insoluble minute particles, surfactants, and fibers together in the form of a planar layer having a thickness regulated in the approximate range of about 0.3 to 5 mm on a substrate and bringing 15 to 150 parts by weight of water and/or steam into contact with said planar layer without disturbing the constitution of said planar layer.
- 3. A method for the production of an absorbent material comprising spreading 100 parts by weight of absorbent resin particles and 0.1 to 10 parts by weight of at least one absorption auxiliary selected from the group consisting of water-insoluble minute particles, surfactants, and fibers together in the form of a planar layer having a thickness regulated in the approximate range of about 0.3 to 5 mm on a substrate and bringing 3 to 30 parts by weight of water and 5 to 50 parts by weight of a polyhydric alcohol into contact with said planar layer without disturbing the constitution of said planar layer.
- 4. A method for the production of an absorbent material comprising spreading 100 parts by weight of absorbent resin particles in the form of a planar layer having a thickness regulated in the approximate range of about 0.3 to 5 mm on a substrate and bringing 15 to 150 parts by weight of water and/or steam into contact with said planar layer without disturbing the constitution of said planar layer, wherein said bringing of water and/or steam into contact with said planar layer causes mutual adhesion of said absorbent resin particles when said particles are moistened.
- 5. The method for the production of an absorbent material according to claim 4, wherein said adhesion is not the result of a covalent bond between particles.
- 6. The method for the production of an absorbent material according to claim 4, wherein said water and/or steam is brought into contact with said planar layer without substantial shearing force on the absorbent resin particles.
