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.
An absorbent member comprising at least one region which comprises an absorbent material, wherein said absorbent material 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, wherein said plurality of absorbent gelling particles are spontaneously connective through said absorbent property modification polymer in response to an application of urine, and wherein when said absorbent material swells by absorbing a urine and is formed into a predetermined layer of the swollen absorbent material under a predetermined load, said layer of the swollen absorbent material has a Gel Bulk Density (GBD) value of below 0.95 g/cm.sup.3 in the GBD test.
An absorbent member comprising at least one region which comprises an absorbent material, wherein said absorbent material 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, wherein said plurality of absorbent gelling particles are spontaneously connective through said absorbent property modification polymer in response to an application of urine, and wherein when said absorbent material swells by absorbing a urine and is formed into a predetermined layer of the swollen absorbent material, said layer of the swollen absorbent material has a Saline Flow Conductivity (SFC) value of at least 20.times.10.sup.-7 cm.sup.3 sec/g in the SFC test.
An absorbent member comprising at least one region which comprises an absorbent material, wherein said absorbent material 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, wherein said plurality of absorbent gelling particles are spontaneously connective through said absorbent property modification polymer in response to an application of urine, and wherein when said absorbent material swells by absorbing a urine and is formed into a predetermined layer of the swollen absorbent material, said layer of the swollen absorbent material has a Ball Burst Strength (BBS) value of at least 30 gf in the test.
An absorbent member comprising at least one region which comprises an absorbent material, wherein said absorbent material 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, wherein said plurality of absorbent gelling particles are spontaneously connective through said absorbent property modification polymer in response to an application of urine, and wherein when said absorbent material swells by absorbing a urine and is formed into a predetermined layer of the swollen absorbent material, said layer of the swollen absorbent material has a Compression Recovery (CR) value of at least 15% in the CR test.
