An absorbent article 1 has an extensible absorbent member 4 and is extensible as a whole. The absorbent member 4 has three-dimensionally dispersed therein a large number of small absorbent clusters 10a or 10b containing a superabsorbent polymer 11 and fibers 12, 13, 14. The small clusters 10a or 10b are dispersively arranged in a web containing crimped fibers. The small clusters include those composed of a superabsorbent polymer particle 11 and a large number of fibers 12 adhered to the particle 11 and those composed of a helically crimped fiber 13, a superabsorbent polymer particle 11, and fibers 14, the polymer particle 11 and the fibers 14 being taken into the helix of the crimped fiber 13.
An absorbent article having extensibility as a whole and comprising an extensible absorbent member having a number of small absorbent clusters dispersed therein in three dimensions, the small absorbent clusters containing a superabsorbent polymer and fibers.
An absorbent article having extensibility and designed not to be less absorbent when 150% extended in its longitudinal direction than before being extended.
A stretchable absorbent member comprising a web containing crimped fiber, the web having a number of small absorbent clusters dispersed in the web in three dimensions, the absorbent cluster containing a superabsorbent polymer particle and fibers.
