Abstract
An absorbent material produced by mixing 100 parts by weight of an absorbent polymer with 1 to 80 parts by weight of synthetic pulp in the presence of 1 to 40 parts by weight of water, an absorbent body produced by mixing 100 parts by weight of an absorbent polymer with 1 to 80 parts by weight of synthetic pulp in the presence of 1 to 40 parts by weight of water, dry mixing the resultant mixture with 10 to 1,000 parts by weight hydrophilic fibers based on 100 parts by weight of the absorbent polymer, pneumatically molding the resultant mixture in the form of web, and thermally compressing the resultant web to a density in the range of from 0.1 to 1.0 g/cm.sup.3, and a method for production thereof.
