Abstract
Description
前記第1伸縮性不織布と前記非伸縮性シートとの貼り合せ部分、及び、前記第2伸縮性不織布と前記非伸縮性シートとの貼り合せ部分における、前記長手方向及び前記幅方向についての破断最大強度が20N/50mm以上である吸収性物品である。
図1から図9より、複合シート1について説明する。図1及び図2に示すように、本発明における複合シート1は、伸縮性不織布2と非伸縮性シートである非伸縮性不織布3とが接着剤4により接着されたシートである。具体的には、複合シート1は、該伸縮性不織布2が伸長された状態で、非伸縮性不織布3と貼り合わされたシートである。
図9を用いて複合シート1の製造方法について説明する。本発明に係る複合シート1の製造方法は、以下のようにして実施される。まず、原反ロール31に巻かれたギア延伸加工前の伸縮性不織布原反5を巻き出す。
本発明にかかる複合シート1は、例えば、吸収性物品であるパンツ型使い捨ておむつ50に使用することができる。以下、上述した複合シート1を使用したパンツ型使い捨ておむつ50について詳細に説明するが、パンツ型使い捨ておむつ50のうち着用者の身体に向けられる側を肌当接面側とし、肌当接面側とは反対側を非肌当接面側とする。
図12に示すように、以下に吸収性物品であるパンツ型使い捨ておむつ50の製造方法について説明する。図12は、使い捨ておむつ50の製造工程を説明する図であるが、該使い捨ておむつ50における非肌当接面側を表面側としており、肌当接面側を裏面側として示している。
以下、本発明の実施例を説明するが、これらの実施例は本発明を好適に説明するための例示にすぎず、何ら本発明を限定するものではない。尚、以下においてMD方向とは、上述の実施形態(図1、図5など)における横方向(Direction M)に該当し、いわゆるマシン流れ方向を指し、CD方向とは、上述の実施形態(図1、図5)などの縦方向(Direction C)に該当し、いわゆるマシン流れ方向に直交する方向を指す。
