| Outline of Final Research Achievements |
Using various microscopic techniques,morphological observations and analyses were performed on the traditional Okinawa textile,Bashofu,and its material,Itobasho.In addition,Bacterial treatment during the process of Bashofu fiber extraction was investigated.Bashofu textile is classified into three classes according to their hardness and softness: Waha(hard used for interior decoration),Nahau(soft used for obi belts of kimono),and Nahagu(very soft used for kimono cloth).As the results of this study,we found that Nahagu thread was thinner than Waha thread,the cell walls of cells constituting fibers in Nahagu were thinner than those in Waha and Nahau,and the content of lignin,one of the components of cell walls,in Nahagu was lower than that in Waha and Nahau.We also succeeded in isolating a bacterial strain suitable for fiber separation,and treatment with this bacterial strain made it possible to separate fibers from hard materials,which was not possible with the traditional method.

芭蕉布のなかでもナハグ繊維は上質で柔らかな着尺用繊維として知られているが,このナハグ繊維が同じイトバショウ植物体から生産されるワーハやナハウ繊維と比べ,なぜ柔らかいのかははっきりとしない.本研究により,このナハグ繊維の持つ形態的・化学的な特性が明らかになり,今後の芭蕉布の生産において着尺用の柔らかい糸を作るときの指標になると考えられる.また植物を材料とする繊維生産において,栽培,育種,採繊工程を検討するときの特質と捉えることができる.単離した菌の利用により,これまで着尺用としては利用できなかった材料についても採繊の道がひらけ,材料不足が原因で減少していた芭蕉布生産の増産策になるであろう.
