Cellulose fibres and nanofibres have gained interest because of the high strength and 
firmness, biodegradability and renewability [1]. The manufactures of polymer 
nanofibres via electrospinning technique have been perceived as a persuasive system for 
producing fibres with submicron diameters by electrostatic forces [2]. 
In this work, the possibility of preparing cellulose nanofibres using electrospinning 
method was investigated.
The condition of electrospinning was following: the distance between the needle tip 
and collector was set to 14 cm. The collector used was aluminum foil with the width of 
21 cm. The inner diameter of the needle was 0.353 mm. Injection rate of the spinning 
solution was 0.03-90 mkl/min. The collecting time is 120 min, voltage 0.5-30 kV. After 
electrospinning, the obtained cellulose fibres were peeled from the collector and 
vacuum-dried at 60
0
C for 1 h. Electrospinning system (NanoNC eS-robots, South 
Korea) was used for the fabrication of nanofibers. The relative humidity and 
temperature during the spinning process was 60% and 25
°
C, respectively. 
The optic microscopy method showed that nanofibres are formed with different 
diameters (nano and micro sizes). Atomic force microscopy studies have also confirmed 
the formation of nanofibers with diameters ranging from nanometers to micrometers. 
IR spectroscopic studies of cellulose nanofibers showed that nanofibres are 
characterized by spectra typical of cellulose, however, new absorption bands are 
observed.
