  • Patent number: 8247639
    Abstract: 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.

  • Patent number: 7432412
    Abstract: An absorbent article having a substantially oblong rectangular absorbent body A composed of a topsheet 2, a backsheet 3, and an absorbent core 4 between the topsheet 2 and the backsheet 3. The absorbent article further has a pair of side sheets 5 as leak preventive side members on its skin facing side C of the absorbent body A. The leak preventive side members have a pattern P printed with ink in a configuration such that the printed ink is substantially kept away from contact with the skin of a wearer.
