い。As described above, in the present invention, the outer cylinder of the defibrating machine (16) is used.
Since the bamboo pieces (1C) are introduced from the side surface of (18), the bamboo pieces (1C) are oriented in the defibrating machine (16) so as to be substantially along the axial direction of the inner cylinder (20), and therefore, The long axis of the piece (1C) is substantially along the blade edge (21A) of the impeller (21) of the inner cylinder (20), and in this state, the bamboo piece (1C) is defibrated. (1C) is hardly affected by the defibrating force in the long axis direction, and the resulting fiber (1D) maintains the length of the bamboo piece (1C) without breaking, generating short fibers and finely pulverized materials. Is minimized and 30
Long fibers of mm to 100 mm are easily manufactured. Conventionally, in a normal defibrating machine, an input port of a material to be crushed is provided at an upper portion of an outer cylinder. In this case, the long axis of the bamboo piece is substantially perpendicular to the blade edge of the impeller, so that the bamboo piece is crushed in the long axis direction and easily broken, and a large amount of short fibers and finely pulverized materials are generated. Therefore, in this case, it is almost impossible to produce bamboo fibers having a fiber length of 10 mm or more.
