Abstract
【解決手段】表面シート3が肌側に配設されたセルロース系繊維からなる非熱融着層10と、非肌側に配設された熱融着性繊維からなる熱融着層11とを含む多層構造からなり、表面シート3の非肌側に、熱融着性繊維からなるセカンドシート6が配設され、セカンドシート6の非肌側面に、セカンドシート6及び表面シート3を一体的に肌側に向けて窪ませた多数の圧搾部15…が形成されている。前記非熱融着層10と熱融着層11とは、互いの繊維が交絡して接合されている。前記セカンドシート6は、熱融着層11より低目付かつ低密度で形成されている。前記圧搾部15は、間欠的なパターンで形成されている。

Description
前記表面シートとセカンドシートとの積層体を、表面が平坦な加熱しないフラットロールと、表面に前記圧搾部に対応する多数の凸部が形成された、少なくとも圧搾時に加熱する凸ロールとの間を通過させることにより、前記セカンドシート及び熱融着層の熱融着性繊維を熱融着して接合すると同時に、前記圧搾部を形成することを特徴とする吸収性物品の製造方法が提供される。
前記表面シートを、表面が平坦な加熱しないフラットロールと、表面に多数の凸部が形成された少なくとも圧搾時に加熱する凸ロールとの間を通過させることにより、前記表面シートの非肌側面に、前記熱融着層及び非熱融着層を一体的に肌側に向けて窪ませた多数の中間圧搾部を形成した後、表面が平坦な加熱しない第2のフラットロールと、表面に前記圧搾部に対応する多数の凸部が形成された少なくとも圧搾時に加熱する第2の凸ロールとの間を通過させることにより、前記セカンドシート及び熱融着層の熱融着性繊維を熱融着して接合すると同時に、前記圧搾部を形成することを特徴とする吸収性物品の製造方法が提供される。
本発明に係る生理用ナプキン1は、図1〜図3に示されるように、ポリエチレンシートなどからなる不透液性の裏面シート2と、肌当接面をなし、体液を速やかに透過させる表面シート3と、これら両シート2、3間に介装された綿状パルプまたは合成パルプなどからなる吸収体4と、この吸収体4の形状保持および拡散性向上のために前記吸収体4の少なくとも肌側面及び非肌側面を覆うクレープ紙又は不織布などからなる被包シート5と、前記表面シート3と吸収体4との間に介在されたセカンドシート6と、前記吸収体4の略側縁部を起立基端とし、かつ少なくとも着用者の体液排出部Hを含むように前後方向に所定の区間内において肌側に突出して設けられた左右一対の立体ギャザーBS、BSを形成するサイド不織布7、7とから主に構成され、かつ吸収体4の周囲においては、その上下端縁部では前記裏面シート2と表面シート3との外縁部がホットメルトなどの接着剤やヒートシール、超音波シール等の接合手段によって接合され、またその両側縁部では吸収体4よりも側方に延出している前記裏面シート2とサイド不織布7とがホットメルトなどの接着剤やヒートシール、超音波シール等の接合手段によって接合されている。図示例においては、吸収体4は1層構造となっているが、中高部を形成する多層構造としてもよく、また、同一の大きさ、形状の吸収体を重ねた多層構造としてもよい。
前記表面シート3は、吸収体4の肌側を覆う部分である肌当接面を形成するものであり、図4に示されるように、肌側に配設されたセルロース系繊維からなる非熱融着層10と、非肌側に配設された熱融着性繊維からなる熱融着層11とを含む多層構造を成している。前記表面シート3は、前記非熱融着層10と熱融着層11とからなる2層構造とするのが望ましいが、その中間にセルロース系繊維や合成繊維などからなる中間層を設けてもよい。
前記セカンドシート6は、前記表面シート3と吸収体4との間であって、前記表面シート3の非肌側に隣接して配設されている。つまり、表面シート3の非肌側層を構成する熱融着層11の非肌側面と、セカンドシート6の肌側面とが対面して配設されている。前記セカンドシート6は、表面シート3とほぼ同形状の平面形状を有しているのが好ましい。このセカンドシート6は、後述するように、前記透液性表面シート3の熱融着層11に対し、圧搾部15における熱融着により接合される。
前記セカンドシート6の非肌側面には、図4に示されるように、前記セカンドシート6及び表面シート3を一体的に肌側に向けて窪ませた多数の圧搾部15、15…が形成されている。前記圧搾部15は、表面シート3の非肌側(熱融着層11の外面側)にセカンドシート6を積層した状態で、前記セカンドシート6の非肌側から圧縮すると同時に熱又は超音波を加えることにより、前記熱融着層11及びセカンドシート6の熱融着性繊維を溶融・固化して、圧搾状態を保形することにより形成した窪み部である。この圧搾部15において熱融着層11とセカンドシート6とが強固に固着され、表面シート3とセカンドシート6とが一体化されている。前記表面シート3及びセカンドシート6の積層体は、肌側面が平坦に形成され、非肌側面に前記圧搾部15…に対応する窪み部が多数形成されている。
次に、前記生理用ナプキン1の製造方法について説明する。ここでは、本発明の特徴である前記圧搾部15を形成する方法について詳細に説明する。その他の工程は、一般的な生理用ナプキンの製造方法と同様である。
