実施例1
帯電メルトブローポリプロピレン微細繊維を含む2枚のシート(350mm×300mm)の一方を他方に重ねて、100g/m2の基本重量、7μm〜8μmの効果的な繊維直径、および約1mmの厚さを有する層化ウェブを形成した。軽量スパンボンドポリプロピレンウェブ(350mm×300mm、50g/m2、タイプ105OB1UO0、Don and Low Nonwovens,Forrar,Scotland、United Kingdomから入手可能)を微細繊維層化ウェブの1面に接触させて配置した。ポリプロピレン支持メッシュ(380mm×78mm、145g/m2、タイプ5173、Inermas,Barcelona,Spainから入手可能)のストリップを、層化微細繊維ウェブの一方の長いエッジから約108mm離隔し、層化微細繊維ウェブの他方の長いエッジから114mm離隔し、微細繊維表面のエッジに上に延在する残りの微細繊維面上に幅方向に配置した。内側被覆シート(350mm×300mm、23g/m2、LURTASIL(商標)6123、Spun Web,UK,Derby,England,United Kingdom)を支持メッシュおよび残りの露出した微細繊維ウェブの上に配置した。次に、5層構造を、層化構造をほぼ矩形形状に超音波で接着し、上部エッジ、底部エッジおよび2つの側方エッジを形成する周長で一緒に層化される構造を維持する接着部を提供した。層を支持メッシュの長いエッジに沿って一緒に接着もした。このようにして接着された構造の長さは、上部エッジおよび底部エッジに平行に測定したところ、188mmであり、幅は、側方エッジに平行に測定したところ203mmであった。支持メッシュのストリップのエッジは、層化構造の上部エッジから60mm離隔し、かつ、その構造の底部エッジから65mm離隔して位置した。接着部周辺をはみ出た余分な材料を除去し、側方エッジで接着線をはみ出た部分すなわち支持メッシュの中心線に近接する部分で、50mmの長さ×20mmの幅を有する部分はそのままにして、ヘッドバンド取付手段を形成した。
第1および第2の層化シート構造(350mm×300mm)を実施例1と同様に製造したが、支持メッシュを省略した点では異なっていた。曲線接着部を各シートの長いエッジに沿って形成し、接着部の凸部をはみ出た余剰材料を除去した。第3の層化シート構成は、実施例1と同様に製造したが、5層各々が実質的に同一の拡がりを有する点では異なっていた。第1の層化シート構造を内側カバーと接触させながら第3のシート構造の上に配置した。第1および第3のシート構造を、第1のシート構造の接着されていない長いエッジ付近の曲線接着部を用いて、165mmの幅および32mmの深さを有する第1の楕円状呼吸器保護装置部材を形成した。曲線接着部の各半径は145mmだった。
