带有异型分布的吸收材料的吸收芯
摘要：
本发明公开了一种用于吸收制品(20)诸如尿布的吸收芯(28)。所述芯包括具有顶侧面(288)和底侧面(290)的芯包裹物(16,16’)；介于顶侧面和底侧面之间的吸收材料(60)；第一纵向延伸的通道形成区域和第二纵向延伸的通道形成区域(26a,b)，该通道形成区域设置在纵向轴线(80)的相反两侧上并且基本上不含吸收材料，优选地芯包裹物的顶侧面通过该通道形成区域附接到芯包裹物的底侧面。芯具有介于第一通道形成区域和第二通道形成区域之间的中心吸收区(62)以及侧向向外设置的第一侧向吸收区和第二侧向吸收区(61,63)。中心吸收区中的吸收材料的平均基重低于侧向吸收区中的吸收材料的平均基重。
摘要（英）：

An absorbent core (28) for absorbent articles (20) such as diapers. The core comprises a core wrap (16, 16') comprising a top side (288) and a bottom side (290), an absorbent material (60) between the top side and the bottom side, a first and second longitudinally-extending channel-forming areas (26a, b) disposed on opposite sides of the longitudinal axis (80) and substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap. The core has a central absorbent zone (62) between the first and the second channel-forming areas and a first and second lateral absorbent zones (61, 63) disposed laterally outwardly. The average basis weight of the absorbent material in the central absorbent zone is lower than the average basis weight of the absorbent material in the lateral absorbent zones.
