Claims (6)

  1. ａ）既知の幅および厚さを有するダイからフィラメントのストリームを押出すことと、ｂ）押出されたフィラメントを予備的に細化する処理チャンバであって、かつ、互いに平行であり、ダイの前記幅に平行であり、および押出されたフィラメントのストリームの長手方向軸に平行である２つのわずかに隔てられた壁によって画定される処理チャンバを介して、押出されたフィラメントのストリームを方向付けることと、ｃ）前記処理チャンバを通過したフィラメントのストリームをコレクタ上で遮断し、前記フィラメントがそこで不織繊維ウェブとして捕集されることと、ｄ）前記処理チャンバの壁の間隔を選択して、押出されたフィラメントの前記ストリームが広がって、前記ダイの前記幅よりも少なくとも５０ミリメートル幅広の機能性ウェブとして捕集されるようにすることとを含む不織繊維ウェブの調製方法。
  2. 前記平行な壁が、前記フィラメントの移動方向に互いに近接する請求項１に記載の方法。
  3. 前記捕集された機能性ウェブが、前記ダイの前記幅よりも少なくとも２００ミリメートル幅広である請求項１または２に記載の方法。
  4. 前記フィラメントが、前記コレクタに到達する前にダイの前記幅の少なくとも２倍の幅に広がる請求項１または２に記載の方法。
  5. ａ）既知の幅を有するダイからフィラメントのストリームを押出すことと、ｂ）押出されたフィラメントを予備的に細化する処理チャンバであって、かつ、互いに平行であり、前記ダイの前記幅に平行であり、および押出されたフィラメントの前記ストリームの長手方向軸に平行である２つのわずかに隔てられた壁によって画定される処理チャンバを介して、押出されたフィラメントのストリームを方向付けることと、ｃ）前記フィラメントの前記ストリームをコレクタ上で遮断し、前記処理されたフィラメントがそこで不織繊維ウェブとして捕集されることと、ｄ）前記処理チャンバの壁の間の間隔を選択し、エアナイフから下流の前記処理チャンバの主な長さにわたって、前記フィラメントの移動方向に互いに遠離するようにこれらの壁を配置し、それによって、前記押出フィラメントのストリームが、前記ストリームがコレクタに到達する前に前記ダイの前記幅よりも狭い選択された幅を有するようになることとを含む不織繊維ウェブの調製方法。
  6. 押出されたフィラメントが、少なくとも８０００ｍ／分の速度で処理チャンバを通過する請求項１〜５のいずれか一項に記載の方法。
