ABSTRACT:
An absorbent member comprising at least one region which comprises an absorbent material in a concentration of from about 60 to 100% by weight. The absorbent material has a improved physical property after swelling and comprises a mixture of (1) a plurality of absorbent gelling particles comprising a water-insoluble, water-swellable polymer, and (2) an absorbent property modification polymer reactive with at least one component included in a urine. When a urine is applied to the absorbent member, the absorbent gelling particles are spontaneously connective through the absorbent property modification polymer. The absorbent material has at least one of the improved absorbent properties after swelling such as (1) liquid permeability, (2) porosity, (3) wet integrity, and (4) recovery property when subjected to external forces.
