Abstract
Description
少なくとも1つの長手方向に延在するチャネル領域によって横方向に離間された2つの長手方向に延在する側面領域を有し、前記吸収性コアはまた、長手方向において、前方セクションと、後方セクションと、前方セクションと後方セクションとの間の股部セクションとを有する。また、チャネル領域は、側部よりも坪量が小さい。
横方向の中央領域の幅は、横方向の各側部領域の幅より小さくてもよい。好ましくは、2つのチャネル領域の幅は約2〜3ミリメートルであり、中央領域の幅は約9ミリメートルである。しかし、吸収性物品の設計によってはバリエーションが生じることがある。
試験方法:
曲げモード(12-92)-柔軟性の試験方法
本発明による吸収性物品は、以下に特定されるように、製品の剛性の少なくとも25%の低下を示す。
試験方法は、製品がその目的のために設計された固定具で折り畳まれたり曲がったりしたときに、製品の柔軟性、剛性または抵抗を規定するために使用される。試験方法は、下着に適用した後に体に合うように製品を形作るために必要とされる力を説明しなければならない。
この力は、テフロン(登録商標)で覆われた下部固定具に載置されている製品が上部固定具において下方に移動する金属ワイヤによって固定具内に折り畳まれるときに生じる抵抗として定義される。
この製品は、水平の平行なテフロン(登録商標)で覆われた2つの支持体上に自由に置かれる。試料は、引張試験装置を用いて、2つの支持体の間の製品の中心線で押し下げられる。次に最大の力が登録される。テストプロセスの詳細な説明は以下の通りである。
引張試験装置 Lloyd LRX等
ロードセル 20N
速度 300mm/分
クロスヘッドの動き 40mm
上部固定具 SCA Hygiene Products ABによって製造された12-92、直径3mmの金属ワイヤー
下部固定具 SCA Hygiene Products ABによって製造された47-07、支持体の断面が直径10mmの円形であり、支持体の中心間の距離は40mmである
タルク ベビーパウダー等
テフロン(登録商標)テープ Stokvisにより製造されたPD420
1. 固定具は、引張試験機に取り付ける必要がある。
2. 下部固定具に製品を置く。上部固定具は、上部金属と製品の間の距離を残して調整する必要がある。始める前に、上部の固定具との接触がないようにしなければならない。
3. ゼロを押す。
4. 試験前に製品の剥離紙を取り除き、粘着性を除去するためにタルクで接着剤を覆う必要がある。
トップシートを上向きにして、下部固定具に製品を置く。上部固定具が製品を中心に正確に会うように製品を中心にする。スタートを押す。
最大の力を登録する必要がある。結果の精度を0.1N単位で(by 1 decimal unit N)記述する。
以下の表1は、従来の失禁ライナーの測定結果を示しているのに対して、下記の表2は、本発明による失禁ライナーの測定結果を示している。両方の試験シリーズは、25回の測定を含む手順に基づいていた。
結論として、従来の失禁ライナーの平均値は1.8408Nであったが、本発明による失禁ライナーの平均値は1.3771Nであった。これは、本発明によるライナーが従来のライナーよりも25.2%少ない製品剛性を有すること、または柔軟性を有することを意味する。
