Description
「接合素子面積」は、一つの接合素子に占有される幾何学的な面積である。異なる面積の接合素子の場合、平均接合素子面積が算出可能である。例えばリング形状の、窪んだ接合素子の場合、接合素子面積は、(孔も含む)接合素子を外周で閉じられる面積と定義される。
図1は、少なくとも一方が熱融解材料を含む、二枚の重なり合うウェブ材料1及び2を概略的に図示している。ウェブ材料はファイバー状の不織布、プラスチックフィルムまたはこれらのラミネートである。さらにウェブ材料は二つ以上の材料レイヤーを備えている。二つのウェブ材料間の重複部分は符号3で示される。重複部分におけるウェブ材料1及び2は、複数個の接合素子を備える接合パターン4によって接合されている。接合は、例えば超音波溶接や、熱接合など熱融解材料が融解されてウェブ材料1及び2を接合させる当該分野で既知の方法によってなされる。こうして、接合された重複部分3は、二つのウェブ材料1及び2を接合する継ぎ目を形成する。この継ぎ目は、図1の二つのウェブ材料と同平面に位置する。両ウェブ材料は重複部分の外側まで延在する部分を有する。
この方法は、繰り返されるロード/アンロードサイクルで伸張性材料がどのように振舞うかを測定する。サンプルは所定の伸張長まで伸張され、0と該所定の伸張長との間での周期運動が実施される。要求されたロード/アンロード張力が記録される。恒久的な、すなわち残存している弛緩した材料の伸張長が測定される。
・クロスヘッドスピード:500mm/min
・クランプ距離:50mm
