  • Publication number: 20120330259
    Abstract: An absorbent product has a top sheet, an absorbent core and a back sheet. The absorbent core includes 40% by weight or more of high absorbent resin powder and it is possible to slim down the absorbent core while keeping a sufficient amount of absorption to thereby achieve slimming down of the absorbent product. A top sheet lower part contacting the high absorbent resin powder in the absorbent core includes hydrophilic fibers having water retention characteristics, and moisture is temporarily retained in the top sheet lower part before reaching the absorbent core and rapidly disperses in a range facing the absorbent core of the top sheet lower part. As a result, it is possible to reliably absorb the moisture of excrement in the absorbent core and to simplify a structure of the absorbent product.
