Description
本発明はセルロースファイバーを処理することによってミクロフィブリル化セルロースを製造する方法に関する。本発明はまた、この方法に従い生成されるミクロフィブリル化セルロースに関する。
セルロースファイバーはセルロースポリマー、すなわちセルロース鎖から形成されている多成分構造体である。当技術で知られているリグニン、ペントサンおよびその他の成分がまた、存在することがある。ファイバー中のセルロース鎖は相互に付着し、基本フィブリルを形成する。数個の基本フィブリルは相互に結合し、ミクロフィブリルを形成し、数個のミクロフィブリルは凝集体を形成する。セルロース鎖、基本フィブリルおよびミクロフィブリル間の結合は水素結合である。
本発明の目的は改善されており、またエネルギー効率の良い様相でミクロフィブリル化セルロースを製造する方法を提供することにある。
本発明は改善されており、またエネルギー効率の良い様相でミクロフィブリル化セルロースを製造する方法に関する。
分解の用語は、ファイバーが短くされ、柔軟にされ、または全てのその他の様相で処理により機械的に影響を受けることを意味する。酵素がスラリー中に均一に分布されることを確実にするために、ファイバーおよび酵素を含むスラリーを攪拌または混合するだけでは、本発明により開示された方法におけるようにはファイバーは分解されない。本発明に従う組合せ処理によってミクロフィブリル化セルロースの長さは短くされ、従ってこのスラリーの処理ファイバーの長さは格別に減少される。
パインクラフトパルプを80nkat/gの活性を有するエンドグルカナーゼに富む酵素を用いて組合せ機械的処理および酵素処理で処理した。このパルプは20重量%のコンシステンシイを有し、pH5において50℃±3℃の温度で3時間かけて処理した。パルプを次いで、顕微鏡下に検査した。対照として、同一パルプを先ず、組合せ処理の場合と同一の酵素、使用量、pHおよび温度を用い3時間かけてパルプコンシステンシイ5重量%において酵素処理した。

- 前記セルロースに作用する酵素がセルラーゼであり、および/または前記ヘミセルロースに作用する酵素がキシラナーゼであることを特徴とする、請求項5に記載の方法。
- 酵素を、機械的処理に先立って、または機械的処理期間中に添加することを特徴とする請求項1〜6のいずれかに記載の方法。
- 単一処理を圧縮機、シュレッダー、精製装置、デフィビレーター、スクリュー、パルパーまたはボンプ内で行うことを特徴とする請求項1〜7のいずれかに記載の方法。
- スラリーを一回以上の順次単一処理工程で処理することができることを特徴とする請求項1〜8のいずれかに記載の方法。
