のシートに体液を吸収体へ導くための多数の開口を設
け、シート上面を肌接触面とする一方、その下面を吸収
体に接触させる技術が公知である。
【０００３】例えば、米国特許第４，７４１，９４１号
公報には、前記開口としての導液管を有する表面シート
をメルトブロー不織布やスパンボンド不織布製造工程を
利用してつくる技術が開示されている。
【０００４】また、特開平４−８９０５４号公報には、
メルトブロー不織布の一部から前記開口としての導液管

製造技術が開示されている。
【０００５】
【発明が解決しようとする課題】前記両公知技術によれ

できる。メルトブロー繊維は一般に極細であって、これ
を使用した表面シートは肌触りがよい。加えて、この表
面シートには、多数の繊維間隙があり、肌と着用物品と
の間の通気性をよくすることができる。しかし一方で
は、それら繊維間隙の存在により、吸収体に体圧がかか
ると、浸透した体液が吸収体から肌へ向かって逆流し易
いという問題がある。
【０００６】そこで、この発明は、表面シートの所要部
位において、肌接触域の耐水度を周辺の領域よりも相対
的に高くすることにより、良好な肌触りを有し、かつ、
体液の逆流防止機能と通気性とを兼ね備えた表面シート
の提供を課題にしている。
【０００７】
【課題を解決するための手段】この発明が前記課題を解
決するために前提とするところは、シート上面側の体液

において、前記肌接触域の耐水度が相対的に高く、前記
第１領域の周辺である第２領域において、耐水度が相対

【０００９】また、この発明の実施態様の一つにおい

【００１０】
【作用】この発明に係る表面シートは、体液を導くため
の開口を設けることにより透液性となる。また、この表
面シートは、メルトブロー不織布を一例とする熱可塑性

ことで繊維間隙を部分的に塞ぎ、耐水度を高くすること
によって、体液の逆流を防止することができる。この第
１領域の周辺である第２領域、例えばおむつの外周は、
そもそも逆流の可能性が低いから、繊維間隙を塞がなく

維持できる。

【実施例】この発明に係る表面シートの詳細を添付の図

接触域１７とを有する。開口１６の上面側の径は０．３

面側の径は上面側の径より大きくても小さくてもよい。
高耐水度領域１１では、肌触りに支障を与えない程度に
不織布を加熱、加圧して繊維１５どうしの融着の度合い
を高めることにより、繊維間隙の多くを塞ぎ、ＪＩＳ

低耐水度領域１３として、熱処理をあまり加えずに繊維
間隙の多くを残してあるから、不織布本来の通気性や柔
