前記ポリマーシートにおける着用者の体液排出部位に対応する領域の肌側面に隣接して、パルプ繊維を含んでなる繊維状吸収体が配設され、
前記高吸水性ポリマーは、前記繊維状吸収体と重なる領域には配置されず、それ以外の領域に配置されていることを特徴とする吸収性物品が提供される。
本発明に係る生理用ナプキン1は、図1及び図2に示されるように、ポリエチレンシート、ポリプロピレンシートなどからなる不透液性裏面シート2と、経血やおりものなどを速やかに透過させる透液性表面シート3と、これら両シート2,3間に介在された2層のシート間に高吸水性ポリマーを配置してなるポリマーシート4と、前記ポリマーシート4の所定位置の肌側面に隣接して配設されたパルプ繊維を含んでなる繊維状吸収体5と、必要に応じて前記透液性表面シート3の非肌側に隣接して配設された親水性の不織布などからなるセカンドシート6と、表面両側部にそれぞれ長手方向に沿って配設されたサイド不織布7,7とから構成されている。また、前記ポリマーシート4の周囲において、そのナプキン長手方向の前後端縁部では、前記不透液性裏面シート2、透液性表面シート3の外縁部がホットメルトなどの接着剤やヒートシール等の接着手段によって接合され、またその両側縁部ではポリマーシート4の側縁よりも側方に延出している前記不透液性裏面シート2と前記サイド不織布7とがホットメルトなどの接着剤やヒートシール等の接着手段によって接合され、外周にポリマーシート4の存在しない外周フラップ部が形成されている。
前記不透液性裏面シート2は、ポリエチレンやポリプロピレン等のオレフィン系樹脂シートなどの少なくとも遮水性を有するシート材が用いられるが、この他にポリエチレンシート等に不織布を積層したラミネート不織布や、さらには防水フィルムを介在して実質的に不透液性を確保した上で不織布シート(この場合には防水フィルムと不織布とで不透液性裏面シートを構成する。)などを用いることができる。近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材は、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートである。
前記不透液性裏面シート2と透液性表面シート3との間に介在されるポリマーシート4は、肌側(透液性表面シート3側)に配置された上層シート10と非肌側(不透液性裏面シート2側)に配置された下層シート11との間に、高吸水性ポリマー12が配置された構造を成している。前記上層シート10と下層シート11との間には、パルプなどの繊維状吸収材が配置されず、粉粒状の高吸水性ポリマー12のみが配置されている。このため、前記ポリマーシート4の厚みを薄くでき、確実に薄型化を図ることができるようになる。
