Claims (16)

  1. Ein Verfahren zum Bleichen einer Nichtbaumwoll-Cellulose-Textilfaser, eines Garns oder Stoffes durch Inkontaktbringen der Textilfaser, des Garns oder Stoffes mit einem Xylanaseenzym für einen Zeitraum und unter Bedingungen, die geeignet sind, um eine Weißfärbung der Textilfaser, des Garns oder Stoffes zu erzeugen.
  2. Das Verfahren gemäß Anspruch 1, wobei die Textilfaser, das Garn oder der Stoff Flachs, Jute, Ramie oder Leinen umfassen.
  3. Das Verfahren gemäß Anspruch 1, wobei das Bleichen vor der Herstellung eines Textilprodukts stattfindet.
  4. Das Verfahren gemäß Anspruch 1, wobei das Bleichen an einem reinen, nicht verschmutzten Textilprodukt stattfindet.
  5. Das Verfahren gemäß Anspruch 3, wobei die Textilfaser, das Garn oder der Stoff anschließend zu einem fertigen Textilprodukt verarbeitet werden.

  8. Das Verfahren gemäß Anspruch 1, wobei die Textilfaser, das Garn oder der Stoff vor der, gleichzeitig mit der oder nach der Xylanasebleichung mit einer Cellulase, Protease, Amylase, Lipase, Oxidoreduktase oder Esterase behandelt werden.
  9. Die Verwendung eines Xylanaseenzyms zum Bleichen einer Nichtbaumwoll-Cellulose-Textilfaser, eines Garns oder Stoffes durch Inkontaktbringen der Textilfaser, des Garns oder Stoffes mit einem Xylanaseenzym für einen Zeitraum und unter Bedingungen, die geeignet sind, um eine Weißfärbung der Textilfaser, des Garns oder Stoffes zu erzeugen.
  10. Die Verwendung gemäß Anspruch 9, wobei die Textiffaser, das Garn oder der Stoff Flachs, Jute, Ramie oder Leinen umfassen.
  11. Die Verwendung gemäß Anspruch 9, wobei das Bleichen vor der Herstellung eines Textilprodukts stattfindet.
  12. Die Verwendung gemäß Anspruch 9, wobei das Bleichen an einem reinen, nicht verschmutzten Textilprodukt stattfindet.
  13. Die Verwendung gemäß Anspruch 11, wobei die Textilfaser, das Garn oder der Stoff anschließend zu einem fertigen Textilprodukt verarbeitet werden.
  14. Die Verwendung gemäß Anspruch 9, wobei die Textilfaser, das Garn oder der Stoff in einem kontinuierlichen Prozess mit einer Xylanase behandelt werden.
  15. Die Verwendung gemäß Anspruch 9, wobei die Textilfaser, das Garn oder der Stoff in einem diskontinuierlichen Prozess mit einer Xylanase behandelt werden.
