Description
好ましくは、スペーサー布は、吸収繊維および超吸収材料を実質的に含まない。
手順:
本方法の原理は、材料の厚さを連続的に測定しながら金属ロッドで5Nの力まで材料をゆっくりと圧縮するものである。結果は、力と伸長のデータ点から構成される。力は、ロッドの接触面積に与えられる圧力に変換される。金属ロッドは円柱状で、10mmの直径を有し、7cm超の直径を有する平らな底部を備える。ロッドは、インストロン試験機の上部取付具における10Nロードセルに搭載される。底部取付具に平板を搭載し、ロッドの下の中央に配置することにより、サンプルを板の上に配置し、板を移動させずに圧縮することができる。ロッドの移動速度は5mm/minである。これらの設定は、「New Mechano 5N」と称されるインストロンBluehillプログラムに予めプログラムされるが、試験を開始する前に、全ての範囲が確実に適切な値に設定されるようにプログラム設定を確認すべきである。変更されたバージョンで運転すると、装置、特に精密なロードセルに損傷を与え得る。
1回目は、サンプルなしの空の運転である。この運転を使用して、鋼板がロッドを停止するゼロ厚さ位置を見つける。空の運転では典型的に、ロッドが金属に衝撃を与えるときに生じる力が急速に増加し、装置が十分に速く埋め合わせることができないことに起因して、ロッドが停止する前に、設定した最大限度より高い力が発生する。ロードセルが損傷を受けずに衝撃に耐えることができるように注意しなければならない。限界最大力およびロッドの速度を低下させる特殊な設定を空の運転のために使用することができる。
サンプルは、試験した材料から打ち抜いた50mm辺の正方形である。材料の厚さが不均一な場合、材料の最も厚い部分からサンプルをとった。ロッドをサンプルの中央にプレスし、各サンプルは運転と運転の間に移動させずに3回試験する。各試験材料の10サンプルを使用して、空の運転を含めて合計30回の測定を行い、各試験材料に31の試験運転を実施する。
試験材料は以下の通りである。
結果は、力対伸長のデータ点一式である。力は、Mecano法で測定した力(N)をロッドの底部面積(m2)で割ることによって圧力に再計算する。
手順:
Edana試験方法WSP110.4(05)破断荷重およびおよび伸びNWまたは米国標準方法ASTMD 882(これに準ずる方法)に従って、本発明によるスペーサー布およびサンプルBの引張試験測定を実施した。使用したINSTRON機は、id:100180;cell 100N id:100182であった。試験サンプルは、25mm幅であり、インストロンで使用した引張速度は100mm/minであった。
図5に示すように、2つのサンプルの引張強度(N)および伸び(%)の値をグラフにプロットする。本発明によるスペーサー布は、製造装置での使い捨て吸収性物品への変換を好都合にする低い伸び(%)を示す。
