Abstract
【解決手段】 おむつ1の前外面シート11と内面シート13との間には、前ウエスト弾性体18が取り付けられ、後外面シート12と内面シート13との間には、後ウエスト弾性体19が取り付けられる。内面シート13の内側には、吸収体30が取り付けられ、吸収体30と内面シート13との間には、一対のレッグカフ40が取り付けられる。レッグカフ40の第1側域は、吸収体30と内面シート13との間で接合され、第2側域42は、吸収体30の横方向Xの外側に延出され、内面シート13に接合されることなくカフ弾性体43が複数本取り付けられている。前後ウエスト域2,3は、縦方向Yに隣接する第1〜第3領域2a〜2c,3a〜3cをそれぞれ有し、各領域に第1〜第3弾性体18a〜18c,19a〜19cが取り付けられている。

Description
おむつは1、シャーシ10から吸収体30を剥離し、各領域を所定の寸法に切り取ってサンプルとして用いた。第1領域2aでは、横方向Xの長さ寸法150mm、縦方向Yの長さ寸法65mm、第2領域2bでは、横方向Xの長さ寸法150mm、縦方向Yの長さ寸法60mm、第3領域2cでは、横方向Xの長さ寸法150mm、縦方向Yの長さ寸法25mmをサンプルとして用いた。各サンプルは、温度約20〜23℃、湿度約60〜65%RHの恒温恒湿にて弾性体の弛緩状態で24時間放置後、引っ張り試験機(インストロンジャパン カンパニイリミテッド製)を用いて測定した。
剛性はテーバー法により、テーバースティフネフテスター(株式会社 安田精機製作所製)を用い測定した。サンプルは、シャーシ10および吸収体30を含むとともに、縦方向Yの長さ寸法を約70mm、横方向Xの長さ寸法を約38.1mmに切り取って用いた。サンプルの厚さ方向の長さ寸法(C)を測定し、このサンプルをチャック中心に触れる程度に挟む。支持ローラとサンプルの間隔を長さ寸法(C)×0.08(mm)に調整し、補助重りをかぶせる。サンプルを左右両方向に回転させ、15度支持刻線と振り子の中心刻とが一致した点で、左側(D)および右側(E)の目盛りを読み取る。剛性は、(D)+(E)/2×(補助重りの数値)/1000×9.807によって求められる。測定は複数回おこなわれ、その平均値をこの実施形態の剛性値としている。
本発明の明細書および特許請求の範囲において、用語「第1」および「第2」は、同様の要素、位置等を単に区別するために用いられている。
