Description
しかし、前記親水性繊維シートに比べて吸収体の方が親水性が低いため、親水性繊維シートに吸収された体液が吸収体側に移行せずに親水性繊維シート内に溜まったままの状態と成りやすい。このため、例えば着用者が座る、寝るなどの状態において脚を組みかえるなどして、腹圧が変化することにより一度に体液が多量に発生した際には、透液性表面シートの表面側において体液が液流れをおこしてしまい、この体液が製品の周縁部まで達してショーツなどを汚してしまう問題があった。
前記透液性表面シートにおいて、裏面側に、表面側よりも高い親水度を付与するとともに、前記親水性繊維シートにおいて、吸収体側の面に、透液性表面シート側の面より高い親水度を付与し、
前記親水性繊維シートの表面側は前記透液性表面シートの裏面側よりも親水度が低く、前記親水性繊維シートの裏面側は前記透液性表面シートの裏面側よりも高いことを特徴とする吸収性物品が提供される。
疎水性繊維不織布からなる透液性表面シートの裏面側に、塗布する界面活性剤の量を任意に変化させて各塗布量における体液の液流れ(mm)、逆戻り(g)の量を測定した。その結果を表1に示すとともに、塗布量と液流れの量との相関性を図5のグラフに、塗布量と逆戻りの量との相関性を図6のグラフにそれぞれ示す。
(1)斜度30度の傾斜板に製品を貼り付ける。
(2)吸収体上端より90mmの位置を滴下開始地点とし、高さ1cmより人工経血を3cc(3cc/20sec)で滴下する。
(3)表面材上を液体が流れた部分の長さを滴下開始地点より測定し、液流れ距離(mm)とする。
(1)内径6mmφのガラス管に1.5ccの馬血を注入し、製品中央部に1Nの力で押さえた状態で滴下する。
(2)注入完了後、1分間置いて、再度注入する。この操作を繰り返し5回行う(計7.5cc注入)。
(3)最後の注入後、滴下地点に1分後に濾紙を敷いて30g/cm2の荷重(1000g/33.3cm2)を30秒間載荷する。
(4)吸収後と吸収前の濾紙重量の差を算出し、逆戻り量(g)とする。
前記透液性表面シートの裏面側に塗布する界面活性剤の量を、実験例1において最もバランス良く体液の液流れおよび逆戻りを少なくすることができた1.58g/m2に固定し、親水性繊維シートの裏面側に塗布する界面活性剤の量を任意に変化させて各塗布量における体液の逆戻り(g)の量を測定した。その結果を表2に示すとともに、横軸を塗布量比率(親水性繊維シート6裏面への塗布量/透液性表面シート3裏面への塗布量)、縦軸を逆戻り量(g)とした図7のグラフ上にプロットした。
Claims (2)
- 透液性表面シートと裏面シートとの間に、吸収体が介在されるとともに、前記透液性表面シートと吸収体との間に親水性繊維シートが配置された吸収性物品において、
前記透液性表面シートにおいて、裏面側に、表面側よりも高い親水度を付与するとともに、前記親水性繊維シートにおいて、吸収体側の面に、透液性表面シート側の面より高い親水度を付与し、
前記親水性繊維シートの表面側は前記透液性表面シートの裏面側よりも親水度が低く、前記親水性繊維シートの裏面側は前記透液性表面シートの裏面側よりも高いことを特徴とする吸収性物品。 - 前記吸収体の裏面シート側の面に、透液性表面シート側の面より高い親水度を付与してある請求項1記載の吸収性物品。
