Abstract:
A body fluids absorbent article comprising:a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core having a body-facing side and a garment-facing side and disposed between said liquid-pervious topsheet and said liquid-impervious backsheet,said core including about 100 to about 200 g/m.sup.2 of fluff pulp, about 20 to about 45 g/m.sup.2 of thermoplastic synthetic fibers and about 120 to about 400 g/m.sup.2 of discrete particles of superabsorptive polymer,said fluff pulp and said synthetic fibers being present in an intermixed state so that the relative ratio of said fluff pulp and said synthetic fibers in said core gradually decreases from said body-facing side towards said garment-facing side in a thickness direction of the core,said polymer particles comprises about 20 to about 100 g/m.sup.2 of first polymer particles which have an initial water absorption rate V of about 40 or higher, and about 100 to about 300 g/m.sup.2 of second polymer particles which have and initial water absorption rate V of about 5 to about 20, andall of said first polymer particles are distributed in a lower zone adjacent said garment-facing side of said core while about 100 to about 200 g/m.sup.2 of said second polymer particles are in an upper zone adjacent said body-facing side of said core and up to about 100 g/m.sup.2 of said second polymer particles are distributed in said lower zone.
