ABSORBENT MEMBERS FOR BODY FLUIDS USING HYDROGEL-FORMING ABSORBENT POLYMER

摘要

Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 50 to 100 % by weight and providing a gelcontinuous fluid transportation zone when in a swollen state. This hydrogelforming absorbent polymer has: (a) a Dynamic Gelling Rate of at least about 0.18 g/g/sec; (b) a Performance under Pressure (PUP) capacity value of at least about 25 g/g under a confining pressure of 0.7 psi (5 kPa); and (c) when the hydrogel-forming absorbent polymer is in the form of particles, a mass median particle size of at least about 100 .mu.m.
