吸收制品以及在润湿时形成槽的吸收芯
摘要：
本发明公开了用于个人卫生的吸收制品(20)，该吸收制品包括液体可透过的顶片(24)、液体不可透过的底片(25)、吸收芯(28)和纤维层(54)。该吸收芯包括芯包裹物以及具有超吸收聚合物(SAP)的吸收材料(60)。芯包裹物包括通过基本上不含吸收材料(60)的一个或多个区域(26)相互粘结的顶侧(16)和底侧(16’)。附加层(54)至少部分地粘结到基本上不含吸收材料的所述区域(26)中的芯包裹物的侧面中的一个。当所述吸收材料溶胀时，该芯包裹物沿着基本上不含吸收材料的所述区域(26)形成一个或多个槽(26’)。在所述吸收芯中形成槽(26’)造成在所述纤维层中形成一个或多个对应的沟槽(29)。芯包裹物粘结部(27)可被设计成在用流体加载时以可控方式分层。具有这些限定特性的吸收芯(28)也受权利要求书保护。
摘要（英）：

An absorbent article (20) for personal hygiene comprising a liquid permeable topsheet (24), a liquid impermeable backsheet (25), an absorbent core (28) and a fibrous layer (54). The absorbent core comprises a core wrap and an absorbent material (60) with superabsorbent polymers (SAP). The core wrap comprises a top side (16) and a bottom side (16') bonded to one other through one or more area(s) (26) substantially free of absorbent material (60). The fibrous layer (54) is at least partially bonded to one of the sides of the core wrap in the area(s) (26) substantially free of absorbent material. When the absorbent material swells, the core wrap forms one or more channel(s) (26') along the area(s) (26) substantially free of absorbent material. The formation of the channel(s) (26') in the absorbent core causes the formation of one or more corresponding ditches (29) in the fibrous layer. The core wrap bond (27) may be designed to delaminate in a controllable manner when loaded with fluid. An absorbent core (28) having these delimitation characteristics is also claimed.
