Description
本明細書において「吸収性物品」とは、主な機能が汚物及び排泄物を吸収かつ保持することである消費者製品を指すために用いられる。吸収性物品には、生理用ナプキン、タンポン、パンティライナー、陰唇間装置、創傷包帯、拭き取り用品、テープ式おむつ及びおむつパンツを含む使い捨ておむつ、再利用可能な外側カバーを有するおむつ用のインサート、成人失禁用おむつ、成人失禁用パッド、並びに成人失禁用パンツが含まれ得る。本明細書において「使い捨て」という用語は、洗濯されること又は他の方法で吸収性物品として再生又は再使用されることが一般に意図されていない吸収性物品を説明するために用いられる(例えば、これらは1回の使用後に廃棄されるように意図され、またリサイクル、堆肥化、ないしは別の方法で環境に適合する方法で処分するように構成されてもよい)。
水蒸気透過率(Water Vapor Transmission Rate、WVTR)を、湿潤カップアプローチを使用して測定し、完全延伸状態におけるテープ式おむつのウエストバンド領域の比率を決定する。特性評価される構造に応じて、ウエストバンド領域から切除された試料は、(ウエストバンド通気性を得るための)物品のすべての層、又は(腰部区域通気性を得るための)ウエストバンド材料を除くすべての層のいずれかを含み得る。水の表面の間に目標の上部空間を達成するように所定の高さまで円筒形のカップを水で満たし、延伸された試料は、カップの上側開口部を覆うように封止される。組み立てたカップをオーブンで特定時間にわたって加熱した後、(この同じ期間中に透過する蒸気に対応する)水分損失の量を重量測定的に求める。WVTR試験カップとして、高さ95mm、ねじ付き開口部における内径が17.8mmの、直線的な壁部を有するガラス製円筒バイアルを使用する。試験前に、23℃±2℃、及び50%±2%の相対湿度で2時間、物品を予め調整する。
WVTR(g/m2/24時間)=([SM(g)-FM(g)]/試料表面積(m2))/24時間
