| Outline of Final Research Achievements |
Fibrillation treatment was performed on mulberry pulp by a wet milling method of stone mill type and by a wet mechanical disintegration method, which are ones for nanocellulose production.
By using the wet milling method of stone mortar, wet beating of kozo fiber to obtain the fiber with highly external fibrillation (fluffing on the fiber surface) was obtained. This means that it has a skeleton similar to that of ordinary kozo fiber, but that it can enhance self-adhesiveness, and that it can be a novel paper conservation material.In a wet mechanical disintegration method in which the raw material dispersion liquid is jetted at high pressure from the nozzle and beaten inside the chamber with high degree, mulberry fibers with different degrees of fibrillation are obtained depending on the number of treatments, which shows an adhesive force close to starch paste, It showed that it could be a safe alternative material.

| Academic Significance and Societal Importance of the Research Achievements |
楮繊維は、我が国の紙本文化財原料として多く用いられているが、同一材料である楮繊維で紙本文化財資料の修復箇所の強化がはかれること。また、生物被害に遭いやすいデンプン糊を代替できることを明かにした。このことは新しい修復材料としてフィブリル化楮繊維が有用であり、修復処理の高度化に寄与するものであることを示している。
