Abstract
Description
また、本発明は、吸収性物品が装着される装着面を有する透液性のトップシートと、不透液性のバックシートとを備え、腹側部、股間部及び背側部を有する外装体と、前記外装体の前記肌側表面に脱着可能に装着された本発明の吸収性物品とを備える、着用物品を提供する。
本発明の一態様(以下「態様1A」という)に係る吸収性物品は、透液性のトップシートと、不透液性のバックシートと、前記トップシート及び前記バックシートの間に配置された吸液性の吸収体とを備え、互いに直交する長さ方向、幅方向及び厚さ方向を有する吸収性物品であって、前記トップシートは、凸部が形成された肌側表面を有する不織布であり、前記吸収体は、前記吸収体を前記厚さ方向に貫通する貫通孔又は前記トップシート側に開口する凹部を有する、前記吸収性物品である。
本発明の一態様(以下「態様1B」という)に係る着用物品は、吸収性物品が装着される装着面を有する透液性のトップシートと、不透液性のバックシートとを備え、腹側部、股間部及び背側部を有する外装体と、前記装着面に脱着可能に装着された、態様1〜態様8のいずれかに係る吸収性物品とを備える、着用物品である。
(1)不織布を切断し、不織布サンプルを作製する。
(2)株式会社キーエンス製のデジタルマイクロスコープVHX−100を使用して、不織布サンプルの切断面に対して垂直の方向からの拡大画像を撮影する。拡大画像は、50本以上の繊維の測定が可能となるような倍率に拡大された画像であり、拡大倍率は、例えば20〜50倍である。拡大画像の撮影の際、不織布サンプルの切断面の最も手前の繊維(イレギュラーに手前に飛び出した繊維を除く)にピントを合わせ、撮影深度(奥行き)を設定する。拡大画像は、3D画像としてPC画面上に作成される。
(3)3D画像を2D画像に変換し、2D画像上に、不織布サンプルの厚さ方向に平行に延在する複数の線を引き、不織布サンプルの厚さ方向に対して+45度〜−45度の角度で配向する繊維の本数をカウントする。
(4)カウントした繊維の本数の、測定範囲内の全繊維の本数に対する割合を計算する。
(5)(1)〜(4)を数回(例えば3〜5回)繰り返し、その平均値を厚さ方向配向繊維の含有率とする。
尿取りパッド100の着用時に加えられる幅方向Yの内側に向かう力によって、トップシート120の肌側表面121は、畝部122以外の部分(例えば、溝部123)を折れ起点として着衣側(バックシート130側)に向けて凸状変形しやすい一方、吸収体140は貫通孔141、第1吸収層140aのうち第2吸収層140bと重ならない部分(低坪量部分)及び圧搾部141,142を折れ起点として肌側(トップシート120側)に凸状変形しやすい。したがって、尿取りパッド100の着用時、トップシート120は吸収体140の貫通孔141内に入り込みやすい。特に、貫通孔141は股間部112に位置するので、トップシート120のうち股間部112に位置する部分が吸収体140の貫通孔141内に入り込みやすい。このため、尿取りパッド100の着用時にトップシート120が押圧されても、トップシート120のうち吸収体140の貫通孔141内に入り込んだ部分は押圧されにくく、この部分における畝部122の形状が維持されやすい。
(1)ウェブの製造
第1層及び第2層の積層体であるウェブを製造した。
第1層を構成する繊維として、ポリエチレンテレフタレートを芯成分とし、ポリエチレンを鞘成分とする同芯芯鞘型複合繊維Aを、耐久親水性の親水油剤でコーティングしたものを使用した。繊維Aの平均繊度は2.2dtex、平均繊維長は45mmである。
上記(1)で製造されたウェブと、図12に示される不織布製造装置300とを使用して、畝溝構造が形成された肌側表面を有する不織布を製造した。
不織布製造装置300における各種設定は、次の通りである。
噴射口332の直径:1.0mm(真円)
噴射口322のピッチ:3.0mm
噴射気体温度:310℃
1つの噴射口あたりの噴射気体風量:5L/分
ウェブ搬送速度:速度100m/分
通気性支持部材310(網状支持部材):70メッシュ
ヒータ部340による加熱処理:加熱処理温度を140℃、通過風速1.2m/秒で6秒間処理
(1)ウェブの製造
第1層及び第2層の積層体であるウェブを製造した。
第1層を構成する繊維として、ポリエチレンテレフタレートを芯成分とし、ポリエチレンを鞘成分とする同芯芯鞘型複合繊維Dを耐久親水性の親水油剤でコーティングしたものと、ポリエチレンテレフタレートを芯成分とし、ポリエチレンを鞘成分とする偏芯芯鞘型複合繊維Eを耐久親水性の親水油剤でコーティングしたものとの混合物(質量比1:1)を使用した。繊維Dの平均繊度は2.2dtex、平均繊維長は45mmである。繊維Eの平均繊度は2.2dtex、平均繊維長は44mmである。
噴射部330による気体噴射処理を行わなかった点を除き、実施例1と同様にして、上記(1)で製造されたウェブを使用して不織布を製造した。
実施例1及び比較例1で製造した不織布の乾燥時厚み及び湿潤時厚みを測定した。
なお、不織布の乾燥時厚み及び湿潤時厚みの測定方法は、上記の通りである。
実施例1で製造した不織布の乾燥時厚みは0.86mm、湿潤時厚みは0.79mmであった。湿潤時厚みは、乾燥時厚みの91%に相当した。
比較例1で製造した不織布の乾燥時厚みは0.78mm、湿潤時厚みは0.62mmであった。湿潤時厚みは、乾燥時厚みの80%に相当した。
トップシートの肌側表面に畝溝構造が形成されていない市販の尿取りパッド(比較品)と、トップシートとして製造例1で製造された不織布を採用した点を除き、比較品と同じ構成を有する尿取りパッド(本発明品)とを使用して、尿吸収時間を測定した。尿サンプルとして、寝たきりの高齢者A、B及びCから採取した尿サンプルA、B及びCを使用した。
