Abstract
Description
ヒステリシス試験は、コンピュータとインターフェイスする市販の引張試験機(例えば、Instron Engineering Corp.(Canton,MA)、SINTECH−MTS Systems Corporation(Eden Prairie,MN)製又はその同等物)を利用する。コンピュータを使用して、試験速度及び他の試験パラメータを制御し、かつデータの収集、計算、及び報告を行う。試験は、23℃±2℃及び湿度50%±2%の実験室条件下で行なわれる。試料は試験前に24時間条件付けされる。
1.適切なつかみ具及びロードセルを選択する。つかみ具は平らな表面を有する必要があり、試料を適応させるために十分に幅広(例えば、少なくとも幅2.54cm)でなくてはならない。また、つかみ具は、試料が試験中に滑らないことを確実にするために十分な力を提供しなくてはならない。試験する試料からの引張応答が、使用するロードセルの許容量の25%〜75%であるようにロードセルを選択する。
2.メーカーの指示に従って試験装置を較正する。
3.グリップ間の距離(標点距離)を25.4mmに設定する。
4.対象となる方向が標点距離方向と平行になるように、試料をつかみ具の平坦面に配置する。試料を上側グリップに取り付け、試料をたるませ、次に下側グリップを閉じる。たるみの予負荷を0.02N/cmに設定する。即ち、たるみが0.02N/cmの力で(10mm/分の一定のクロスヘッド速度で)除去されたときにデータ収集が始まる。ひずみは、0.02N/cmの力での引張試験機のグリップの間の試料の長さである、調整された標点距離(lini)に基づいて計算される。調整された標点距離は試料の初期長さとして取られ、0%のひずみに相当する。試験中の任意の点でのひずみ百分率は、長さにおける変化を、調整された標点距離で割って、100を掛けることによって得られる。
5(a).第1周期負荷:100mm/分の一定クロスヘッド速度で試料を200%のひずみまで引っ張る。つかみ具間で引っ張られた試料の長さをlmaxとして報告する。
5(b).第1周期負荷解除:試料を指定された歪みで30秒間保持し、次にクロスヘッドを100mm/分の一定クロスヘッド速度でその開始位置(歪み0%又は初期試料長、lini)に戻す。試料を緩んだ状態で1分間保持する。
5(c).第2周期負荷:100mm/分の一定クロスヘッド速度で試料を200%のひずみまで引っ張る。
5(d).第2周期負荷解除:次にクロスヘッドを100mm/分の一定クロスヘッド速度でその開始位置(即ち、歪み0%)に戻す。
1.0.02N/cm(lini)のたるみの予負荷でのグリップ間の0.001mm単位の試料の長さ。
2.指定された歪み(lmax)での第1周期のグリップ間の0.001mm単位の試料の長さ。
3.0.02N/cm(lext)の第2周期負荷力でのグリップ間の0.001mm単位の試料の長さ。
4.(lext−lini)/(lmax−lini)*100%として定義された0.01%単位の%永久歪み。
本明細書では、様々な寸法及びそれらの割合が指定される。特に断らない限り、各寸法は、以下の方法により測定される。全ての試験は、約23℃±2℃及び相対湿度約50%±2%で維持される調整室内で行なわれる。本明細書において、試料の幅及び長さは、本明細書に定義されるように、横方向幅及び長手方向長さである。試験前に2時間、試料を約23℃±2℃及び相対湿度約50%±2%で予調整する。
1.実質的に平らで水平な表面に物品を置く。
2.吸収性コアアセンブリを縮小させるように作用する、プロセスによる全ての収縮が引き出されるように、物品を表面に固定する。例えば、物品の長手方向縁部及び/又は吸収性コアアセンブリに沿って物品又は弾性材に適用される、予め収縮させたウエストバンドは、物品を横方向に又はそれぞれ長手方向に縮小してよく、その結果、プロセスによる任意のかかる収縮が引き出される。本物品は、プロセスによる収縮が引き出されて吸収性コアアセンブリを保持できるクランプ又は接着テープで、平らで水平な表面に固定される。
3.本明細書に記載の定義により、その間で各取り付け領域、吸収性コアアセンブリ、任意の未接合領域、及び物品の幅及び/又は長さを測定する点を識別する。これは、臀部を画定することを含む。
4.NISTに準拠するスチール定規を使用して、必要な各寸法を1mm単位で測定する。
5.割合=100%×(第1測定値/第2測定値)の式に従って、全ての必要な割合を計算する。
後述するようなマイクロコンピュータ断層撮影法を使用して、本開示の活性化積層体の1センチメートル当たりのシャーリング数及びシャーリング高さを測定することができる。この方法は、本明細書に記載されているように、第1層を第2層に付着させる2つの平行な直線の付着線間の機械的活性化積層体を測定することのみを意図する。この方法は、追加の層も含むようなこれらの積層体に使用することができる。
