がある。However, the addition of chitosan to clothing currently performed is performed, for example, by immersing the clothing in a chitosan solution, so that the chitosan of the clothing may fall off by washing. However, there is a problem that various effects of the above chitosan are not maintained well. For example, most of chitosan will run off after washing about 3 times, and if dipping is repeated to prevent the run off and chitosan is added, the surface of the garment will be hardened and the design of the garment will be impaired, or the skin will not feel smooth. Occurs. As an addition method other than dipping, it is possible to apply by spraying in a heated state, but in that case, chitosan deteriorates due to high heat, and good effects cannot be expected, which is feared.

When the chitosan solution from the inside of the supply tank 1 is discharged into the solid tank 2 by the nozzle 6, it is solidified by the action of the acid solution 10 to form the continuous linear body R. Then, the continuous linear body R is cut by the low-frequency ultrasonic vibration transmitted from the ultrasonic vibration generator 8 through the acid solution 10. Thus, for example, a random chitosan fiber K having a thickness of 2 decimel and a length of 2 to 5 mm is prepared. The large number of cut and produced chitosan fibers K flow in the solid-state tank 2 to the downstream side, where they are received by one end side of the first conveyor 12 and taken out from the solid-state tank 2.

The chitosan fiber K from which the acid adhering to the surface of the cleaning tank 3 has been removed is flown downstream in the cleaning tank 2, where it is received at one end of the second conveyor 16 and taken out of the cleaning tank 3. . The chitosan fiber K conveyed by the second conveyor 16 is dropped from the other end side of the second conveyor 16, received by the one end side of the third conveyor 18, and introduced into the dryer 4. Chitosan fiber K is the third conveyor 18
It is dried by the heat from the heater 17 when it is transported by
The other end of the third conveyor 18 is dropped into the stacking unit 9 to be stacked. A fan 20 is provided above the inside of the inlet of the stacking unit 9, and the operation of the fan 20 allows the chitosan fibers K on the third conveyor 18 to efficiently fall and collect in the stacking unit 9.
