    • An absorbent article is provided comprising a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet, wherein the absorbent core comprises particles of superabsorbent polymer. An acquisition layer is positioned between the topsheet and the absorbent core for receiving and distributing fluid insults for absorption by the absorbent core. A temporary storage layer is positioned between the acquisition layer and the absorbent core, the temporary storage layer comprising a nonwoven fabric having a capacity to receive and temporarily hold the fluid insults in proximity to the absorbent core for a sufficient time for the fluid insults to be absorbed by the superabsorbent polymer in the absorbent core. In one advantageous embodiment, the acquisition layer has a calculated average pore size greater than 100 μm and the temporary storage layer has a calculated average pore size less than 100 μm.
    • 提供了一种吸收制品,其包括顶片,底片和位于顶片和底片之间的吸收芯,其中吸收芯包括超吸收聚合物颗粒。 采集层位于顶片和吸收芯之间,用于接收和分配用于吸收芯吸收的流体损伤。 临时存储层位于采集层和吸收芯之间,临时存储层包括无纺织物,该无纺织物具有接收和暂时保持流体在接近吸收芯附近的污物足够的时间以使流体损伤成为 被吸收芯中的超吸收性聚合物吸收。 在一个有利的实施方案中,采集层具有大于100μm的计算的平均孔径,并且临时储存层具有小于100μm的计算的平均孔径。
