Abstract
Description
吸収性補助具の主な必要条件は保護である。保護は本質的に3つの基本的な要因に関連し、すなわち、
i)吸収能力(典型的には、吸収性コア1グラム当たりの吸収される液体のグラム−g/gとして測定される、吸収性コアの比吸収能力又はSACに関連する)、
ii)漏れ保護(典型的には、1単位時間当たりの吸収される液体のミリリットル−ml/秒として測定される獲得速度、およびmmで測定される拡散に関連する)、並びに
iii)乾燥(典型的には、再湿潤として、すなわち、特定の条件下で吸収性コアを放置したときの液体のグラムとして測定される)である。
前記で参照された従来技術文書により典拠された広範囲に及ぶ努力にもかかわらず、i)吸収能力、ii)漏れ保護、およびiii)乾燥を同時に提供することができる構造を確認する持続的な必要性が存在する。更に、保護と快適さおよび目立たないことを組み合わせるとともに、前記で考慮された従来技術に固有の欠点を避けることが可能である吸収性物品の必要性が高まっている。
手順:
a)吸収性物品の中央/股領域から方形の試料(300×130mm)を切断する;
b)圧力型板(中央に「空のシリンダー」を有する、300mm×130mm×9mm−515÷522g)および関連する重り(2×2,850g)を試料上にゆっくりと置く;
c)特定の量の試験液(80mL)を方形試料の中央の上に25mL/秒よりも高い流速で注ぎ始める;
d)同時に時間の計測を開始する;
e)液体が試料の表面から消えたときに時間の計測を停止する。
手順:
a)吸収性物品の中央/股領域から3つの隣接する正方形の試料(105×105mm)を切断する;
b)特定量の試験液(15mL)をそれぞれの正方形試料上に注ぐ;
c)試料上にプレキシグラス型板(100×100×8mm−90÷95グラム)および重り(4500グラム)をゆっくりと置く;
d)10分間待つ;
e)型板および重りを取り外し、試料上に計量した濾紙の積み重ね(200g/sqm)を適用し、再び、型板および重りを濾紙上にゆっくりと置く;
f)2分間待つ;
g)濾紙を計量する。
濾紙の重量の増加は、再湿潤重量として記録される。
手順:
a)吸収性物品の中央/股領域から3つの連続的な正方形の試料(100×100mm)を切断する;
b)乾燥した正方形試料をそれぞれ計量する;
c)正方形試料をイノックス・ワイヤ(inox wire)ふるい(Uni番号32メッシュ)の中に入れ、計量する;
d)試験流体を含有するレザバの中にふるいを沈める−試料は完全に浸からなければならない;
e)15分間待つ;
f)ふるいを持ち上げ、トレイ上に置く;
g)ふるいの中の試料から過剰量の液体を重力によって2分間排出させる;
h)試料上にプレキシグラス型板(100×100×8mm−90÷95グラム)および重り(5,000グラム)を適用する;
i)5分間待つ;
l)濡れた試料を含有するふるいを計量する。
試料の重量の増加と乾燥試料の重量との比率は、比吸収能力として記録される。
手順:
a)獲得速度での方法の工程a)〜e)に従う;
b)獲得速度での方法の工程c)〜e)を更に3回繰り返し、それぞれの繰り返しの間は定められた時間待つ。
