Abstract
【解決手段】 横方向に延びるとともに縦方向に離間される複数本のウエスト弾性体が伸長状態で収縮可能に取り付けられている前ウエスト部材および後ウエスト部材、ならびに前後ウエスト部材の非身体側に接合されるクロッチ部材を有する使い捨て着用物品において、前ウエスト部材および後ウエスト部材のうち少なくとも一方は、縦方向に画成されていて横方向の伸張応力が異なる複数の弾性領域を有し、この複数の弾性領域のうち伸張応力が最も高い高弾性領域に位置する第1接合部分に、クロッチ部材が接合されている。
【選択図】図2
Description
上記のように形成されることにより、本実施形態における各弾性領域81〜84における横方向の伸張応力は、高い方から順に、高弾性領域83、ウエスト弾性領域81、レッグ弾性領域84、低弾性領域82となっている。
まず、おむつ1と同じ構成で形成されたおむつを、各弾性領域に切り分けた。具体的には、前後外端縁21,31と平行に、前後外端縁21,31から縦方向に50mmまで、50mmから75mmまで、75mmから140mmまで、140mmから170mmまでの領域をそれぞれ切り出した。ウエスト弾性領域81、低弾性領域82、高弾性域83およびレッグ弾性域84に相当するこれらをそれぞれ、サンプルA,B,C,Dとした。サンプルAは、約940dtexの弾性糸を5本含み、サンプルBは、約780dtexの弾性糸を1本含み、サンプルCは、約940dtexの弾性糸を9本含み、サンプルDは、約780dtexの弾性糸を2本含む。各サンプルは、前後ウエスト部材20,30だけでなく、それぞれの位置に配されたクロッチ部材40およびカバーシート70をも含んでおり、シーム部5で互いに接合されることによって、環状に保たれている。
上治具の上側および下治具の下側がサメ肌状になっている固定式長治具を上下に180mm離間させ、これに、各サンプルA〜Dを、シーム部5の片側が上治具の上に反対側が下治具の下になるように、環状のサンプルの内側に治具をはめることによって固定した。
次いで、この治具を速度300mm/minで動かし、チャック間が460mmになるまで離間させて、動きを反転し、チャック間が180mmになるまで接近させた後、再び動きを反転してチャック間が460mmになるまで離間させた時点の伸張応力を測定した。
従って、おむつ1の有する横方向の伸長応力は、高弾性領域83>ウエスト弾性領域81>レッグ弾性領域84>低弾性領域82の関係を有することがわかった。高弾性領域83は、着用者の腰骨の位置に相当するため、おむつ1は、腰骨の位置における伸張応力が高く、ウエスト開口付近の伸張応力が低くなっている。上記のような構成により、本発明のおむつ1は、着用者に快適な履き心地を提供することができる。
