发明名称 ABSORBENT MATERIALS HAVING IMPROVED ABSORBENT PROPERTY AND METHODS FOR MAKING THE SAME.
摘要 An absorbent material comprising 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. The mixture is made by (i) applying a solution containing an organic solvent, water and the absorbent property modification polymer onto the plurality of absorbent gelling particles, wherein the weight ratio of the organic solvent to the water is at least 50:50, and (ii) removing a portion of the organic solvent and water from the applied absorbent gelling particles. When a urine is applied to the absorbent material, the absorbent gelling particles are spontaneoulsy 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.
