Description
具体的に説明すると,本発明は以下の構成を有する。
すなわち,本発明の使い捨ておむつは,着用者の腹部に接する前身頃と,着用者の背部に接する後身頃と,前身頃と後身頃の間に位置する股下域を有する。そして,前身頃と後身頃は,使い捨ておむつの幅方向の両端部分に設けられたサイドシール部4において,相対する端部が接合される。
ここで,前身頃及び後身頃は,は,それぞれ,本体領域11,21と延出領域12,22を有している。本体領域11,21は,サイドシール部4が幅方向の両端部分に形成された領域である。また,延出領域12,22は,本体領域11,21から股下域の方向に向かって延出し,幅方向における幅が股下域の方向に向かうにつれて漸次狭くなる形状の領域である。
また,本体領域11,21には,一又は複数の第1伸縮部材13,23が,幅方向に沿った伸長状態で配置されている。また,延出領域12,22には,一又は複数の第2伸縮部材14,24が,幅方向に沿った伸長状態で配置されている。
そして,第2伸縮部材14,24は,油剤付着量が,0.1重量%以下となっている。
ここで,本願明細書において,「A〜B」とは,「A以上B以下」であることを意味する。
また,本願明細書において,使い捨ておむつや吸収性本体の「長さ方向」というときは,基本的に,前身頃側と後身頃側を結ぶ方向(図2における上下方向)を意味し,「幅方向」というときは,基本的に,長さ方向に直交する方向(図2における左右方向)を意味する。
吸収性本体3は,前身頃外装体1と後身頃外装体2の間に架橋された状態で保持され,使い捨ておむつ100の着用時おいて,着用者の股下部に位置し,着用者が排泄した尿などの液体を吸収保持する。吸収性本体3は,使い捨ておむつの股下部3を中心に,前身頃1及び後身頃2にかけて配置される。図2に示されるように,吸収性本体3は,吸収体31と,トップシート32と,バックシート33とを備えていればよい。
本実施例では,前身頃外装体と後身頃外装体の本体領域に固定される第1伸縮部材として,旭化成せんい株式会社社製の「製品名:ロイカ(登録商標)」,「製品コード:ポリウレタン繊維(一般名スパンデックス)」(以下,「糸ゴムA」)を用いた。糸ゴムAの油剤付着量は,油剤(鉱物油)が3重量%(平均値)であり,油剤(その他)が2重量%(平均値)であった。また,糸ゴムAの繊度は,470dtexであった。また,糸ゴムAの伸長率は,330%とした。
比較例では,前身頃外装体と後身頃外装体の本体領域に固定される第1伸縮部材,及び延出領域に固定される第2伸縮部材の両方に,上記糸ゴムA(油剤が付着したもの)を用いた。その他の条件については,実施例と比較例を同じものとした。

3…吸収性本体
3a…股下域
4…サイドシール部
11,21…本体領域
