Claims (1)
- 【特許請求の範囲】 1. 木材の断片から繊維を分離する方法であって、木材を光で照射し、該光の 強度が、木材の性質と使用光波長とに応じた、結合が照射木材の中葉に沿っ て切断されて繊維間の結合がゆるくなるような大きなものであり、前記照射 のあと、繊維が機械的に木材の断片から分離されることを特徴とする方法。 2. 赤外から紫外までの範囲から選択される波長を有する光を使用して、木材 の端面を、ある割合の前記結合が切断されるまで、照射することを特徴とす る請求項1記載の方法。 3. 光による処理が、たとえばエクサイマーレーザーからの紫外レーザー光を 用いて実施されることを特徴とする請求項1または2記載の方法。 4. 木材が、木材の周囲の空気にオゾンを生成するように選択される光波長で 照射され、生成されるオゾンガスが繊維間の結合を切断し、またゆるくする のに寄与することを特徴とする請求項1〜3の中の1つ以上に記載の方法。 5. 木材が、パルスの形の光で、繊維間の結合を確実にゆるくするのに十分な 数のパルスによって照射されることを特徴とする請求項1〜4の中の1つ以 上に記載の方法。 6. 光照射中に、流体または蒸気の形の液体が木材に加えられることを特徴と する請求項1〜5の中の1つ以上に記載の方法。 7. 繊維が研削法によって木材断片から分離されることを特徴とする請求項1 〜6の中の1つ以上に記載の方法。 8. 所定の流量の液体が分離工程に加えられることを特徴とする請求項1〜7 の中の1つ以上に記載の方法。 9. 機械的に分離されたあとの繊維を所定波長の光で処理して、繊維から残留 リグニンを除去し、かつ原繊維を所望の程度まで暴露するようにすることを 特徴とする請求項1〜8の中の1つ以上に記載の方法。
