基本重量
複合材材料の基本重量は、材料ウェブから10cm×10cmのサンプルをダイ打抜きして、サンプルを計量装置上で10分の1グラムまで秤量して測定した。3個の複製を秤量して平均し、下の表1に報告する。
不織布複合材の引張り強さは、ASTM D882に従って、インストロンモデル1122定速伸展引張り試験機で測定した。縦方向をウェブの縦方向(MD)として、複合材ウェブから25mm幅×76mm長さのサンプルを切断した。初期ジョー間隔76mmでサンプルを試験機のジョーに取り付けた。次にサンプルの破壊点に達するまで、30.5cm/分の速度でジョーを引き離した。サンプル降伏点負荷をポンドで記録した。4個の複製を試験して共に平均し、kg/cm単位の降伏点負荷の値に変換した。
135度剥離試験を使用して、不織布ループ複合材サンプルから、ミネソタ州セントポールの3M社(3MCo.(St.Paul,MN)からのメカニカルファスナーフック材料(KN−3457)のサンプルを剥離するのに必要な力の量を測定した。両面粘着テープを使用して、ループ試験材料の5.1cm×12.7cm断片を5.1cm×12.7cmの鋼パネル上にしっかり付けた。ループ材料の横方向をパネルの長さに平行にして、パネル上にループ材料をのせた。長さをウェブの縦方向にして、1.9cm×2.5cmのフックファスナーのストリップを切断した。2.5cm幅×20cm長さの紙製リーダーをフックストリップの一端の滑らかな面に付着した。次にストリップとループ材料の間に1.9cm×2.5cmの接触領域があり、ストリップの前端がパネルの長さに沿うように、フックストリップをループ材料の中心にのせた。次に1000gローラーを使用して、1分あたりおよそ30.5cmの速度で、ストリップおよびループ材料ラミネートを手で各方向に2回ロール掛けした。次にサンプルを135度剥離ジグに入れた。ジグをインストロンモデル1122引張り試験機の下側ジョー内に入れた。紙製リーダーの自由端を引張り試験機の上側ジョーに入れた。1分あたり30.5cmのクロスヘッド速度、および1分あたり50.8cmのチャート送り速度に設定したチャート式記録計を使用して、ループ材料からフックストリップが135度の一定角度で剥離する際の剥離力を記録した。4つの最高ピークの平均をグラムで記録した。ループ材料からメカニカルファスナーストリップを取り外すのに必要な力をg/cm幅で報告した。各フックループ組み合わせで、12個の複製を試験して平均した。剥離強さをループ複合材の基本重量で除して剥離強さを正規化し、複合材の単位重量あたりの剥離強さを得た。
動的剪断試験を使用して、不織布ループ複合材材料サンプルからメカニカルファスナーフック材料サンプルを剪断するのに必要な力の量を測定した。135度剥離試験で上述したのと同一のフック材料を使用して、剪断試験を実施した。ループ材料の2.5cm×7.5cmサンプルを切断し、幅はフックの縦方向であった。次にこのループサンプルをループの裏面において3M荷造テープで強化した。1.25cm×2.5cmのフックサンプルもまた調製した。長さはフックの縦方向である。このサンプルを2.5cm幅×7.5cm長さの3M荷造テープのタブの端にラミネートした。フックのない端では、荷造テープを折り返して接着剤を覆った。次にループタブが第1の端を通過して伸び、フックタブが第2の端を通過して伸びるように、長いタブ方向を互いに平行にしてフックをループの中心にのせた。5kgのゴム被覆鋼ローラーを使用し、手で前後に5回ロール掛けしてフック材料をループ材料と係合した。アセンブルしたタブをインストロンモデル1122引張り試験機のジョー内に入れた。フックタブを上部ジョーに入れ、ループタブを下側ジョーに入れた。1分あたり30.5cmのクロスヘッド速度、および1分あたり50.8cmのチャート送り速度に設定したチャート式記録計を使用して、フックストリップが180度の一定角度でループ材料から剪断する際の剪断力を記録した。最大負荷をグラムで記録した。ループ材料からメカニカルファスナーストリップを剪断するのに必要な力を、g/cm−幅で報告した。各フックループ組み合わせで、8個の複製を試験して平均した。剪断強さをループ複合材の基本重量で除して剥離強さを正規化し、複合材の単位重量あたりの剪断強さを得た。
各隆線間に溝があり、1センチメートルあたりおよそ4本の隆線があるように離間した軸方向に平行な隆線がある、機械加工された第1および第2のかみ合い波形成形ローラー間のニップに、ジョージア州アセンズのファイバー・ビジョン(Fiber Vision(Athens,Georgia))からのポリプロピレンカード不織布ウェブ(T196、4デニール繊維、40g/m2)を供給して、米国特許第5,643,397号明細書で例証され述べられる方法を使用して、不織布ループ複合材を調製した。約0.7mmの幅を有する平頂−表面を有するように各隆線を機械加工した。不織布の長さに沿って弓形部分および固着部分があり、各弓形部分は高さが約0.33cmであり、長さが不織布の長さに沿って約0.33センチメートルであり、各固着部分が約0.07センチメートル幅であるように不織布の波形シートを成形した。第1の波形成形ローラーを93℃に加熱し、一方第2の波形成形ローラーを149℃に加熱した。固着部分がバッキング層に包埋され、基本重量28g/m2を有する熱可塑性バッキング層を形成するのに適切な量で、第2の波形ロールと冷却ロールの間のニップの直前に、ダイ温度246℃で従来のコートハンガーダイを通して、ミシガン州ミッドランドのダウ・ケミカル(Dow Chemical(Midland,MI))からのポリプロピレン衝撃共重合体(7C50)を波形不織布の固着部分に押出して、繊維シートを形成した。
