Abstract
This study investigated the change in color of acetylated wood by the combined treatment of light and heat. The color of acetylated wood was stable against light, however, heat treatment after light-irradiation made it change greater. Furthermore, the acetylated wood discolored greater than unacetylated one by light-irradiation after heat treatment. These results show that the acetylated wood is not stable when it is exposed under special condition.
Zusammenfassung
In dieser Arbeit wurde die Farbänderung von acetyliertem Holz bei einer kombinierten Behandlung mit Licht und Wärme untersucht. Die Farbe von acetyliertem Holz war zwar lichtstabil, eine auf die Lichtbestrahlung folgende Wärmebehandlung verursachte jedoch eine grössere Farbveränderung. Darüber hinaus verfärbte sich acetyliertes Holz stärker als unacetyliertes bei Lichtbestrahlung nach einer Wärmebehandlung. Diese Ergebnisse zeigen, dass acetyliertes Holz unter besonderen Bedingungen nicht farbstabil bleibt.
