<p>PURPOSE:To obtain an absorbing material useful for sanitary napkin, paper diaper, incontinent pad, mother's milk pad, medical pad, agricultural and horticultural water retaining material, etc., having specific values in density, amount absorbed under pressure and removal ratio of absorbing polymer, consisting mainly of a water absorbing polymer and hydrophilic fibers. CONSTITUTION:The objective absorbing material consisting mainly of a water absorbing polymer [preferably crosslinked polymer of water-soluble ethylenic monomer consisting essentially of acrylic acid (salt)] and hydrophilic fibers (e.g. wood pulp fibers) and having 0.1-0.5g/cm<3> density, 11-25g/g amount absorbed of sodium chloride injection under pressure and <=45% removal ratio of absorbing polymer. The amount of the hydrophilic fibers is preferably 5-500 pts.wt. based on 100 pts.wt. water absorbing polymer.</p> |
