- 繊維の液状懸濁液(suspension)を用意し、
繊維を破砕、こう解(beating)、または切断しないように、単一の移動面を用いてフィブリル化繊維(fibrillated fiber)を作成するように繊維をせん断リファイニング(shear refining)し、そして
続いて、フィブリル化繊維からナノファイバーを分離するようにフィブリル化繊維をクローズドチャネルリファイニング(closed channel refining)または均質化(homogenizing)し、
繊維懸濁液はせん断リファイニングから次続のクローズドチャネルリファイニングへおよびそこを通って連続的かつ一続きで流れ、そしてせん断リファイニングからクローズドチャネルリファイニングへの繊維懸濁液の流量は制御され、処理後のナノファイバーは50から0のカナディアン・スタンダード・フリーネス評価を有する、
ナノファイバーを作成するための方法。 - 分離されたナノファイバーを残りのフィブリル化またはコア繊維から実質的に分離することをさらに含む、請求項1に記載の方法。
- クローズドチャネルリファイニングまたは均質化が繊維コアからナノファイバーを追加的に作成する、請求項1に記載の方法。
- クローズドチャネルリファイニングは、フィブリル化繊維からナノファイバーを分離し、繊維コアを残し、そして繊維コアから追加のナノファイバーを作成するように、最初に第1のせん断速度(shear rate)であり、次いで、第2のより高いせん断速度である、請求項1に記載の方法。
- 液状懸濁液における繊維のせん断リファイニングはナノファイバーが付着された繊維コアを生み、そしてクローズドチャネルリファイニングまたは均質化が繊維コアからナノファイバーを分離する、請求項1に記載の方法。
- フィブリル化繊維のクローズドチャネルリファイニングは、フィブリル化繊維をせん断、粉砕、こう解および切断することによるものである、請求項1に記載の方法。
- 繊維懸濁液がせん断リファイニングからクローズドチャネルリファイニングまたは均質化へ連続して流れる、請求項1に記載の方法。
- せん断リファイニングまたはクローズドチャネルリファイニング中に生じた熱を繊維懸濁液から取り除くことをさらに含む、請求項1に記載の方法。
- 相対的に相互に関して移動する歯の間に繊維懸濁液を通すことによりクローズドチャネルリファイニングが遂行され、該歯はフィブリル化繊維からナノファイバーを分離するのに十分なせん断力を繊維懸濁液の繊維に与えるように離間されそして選択的に繊維コアから追加のナノファイバーを作成する、請求項1に記載の方法。
- 繊維懸濁液を加圧し、該加圧された繊維懸濁液を、フィブリル化繊維からナノファイバーを分離しそして選択的に繊維コアから追加のナノファイバーを作成するのに十分なせん断力を繊維懸濁液の繊維に与えるような圧力および寸法の口を通過させることにより均質化が遂行される、請求項1に記載の方法。
- 付着されたナノファイバーを有する繊維コアからなるフィブリル化繊維の液状懸濁液を用意し、そして
繊維コアからナノファイバーを分離しそして繊維コアから追加のナノファイバーを生成するように、最初に第1のせん断速度で、続いて第2の、より高いせん断速度でフィブリル化繊維をクローズドチャネルリファイニングまたは均質化し、

ナノファイバーを作成する方法。 - フィブリル化繊維のクローズドチャネルリファイニングは、フィブリル化繊維をせん断、粉砕、こう解および切断することによるものである、請求項11に記載の方法。
- 繊維懸濁液は、第1のせん断速度で作動する第1のロータから第2のせん断速度で作動する第2ロータに連続して流れる、請求項11に記載の方法。
- 繊維懸濁液は、第1のせん断速度で作動する第1のロータから第2のせん断速度で作動する第2ロータに連続して直列に流れ、そして繊維懸濁液の流量を制御することをさらに含む、請求項11に記載の方法。
- クローズドチャネルリファイニング中に生じた熱を繊維懸濁液から取り除くことをさらに含む、請求項11に記載の方法。
- 相対的に互いに移動する一組の歯間に繊維懸濁液を通過することによりクローズドチャネルリファイニングが遂行され、該歯はフィブリル化繊維からナノファイバーを分離しそして繊維コアから追加のナノファイバーを作成するのに十分なせん断力を繊維懸濁液の繊維に与えるように離間される、請求項11に記載の方法。
- 繊維懸濁液を加圧し、該加圧された繊維懸濁液を、フィブリル化繊維からナノファイバーを分離しそして繊維コアから追加のナノファイバーを作成するのに十分なせん断力を繊維懸濁液の繊維に与えるような圧力および寸法の口を通過させることにより均質化が遂行される、請求項11に記載の方法。
