A device for production of nanofibers through electrostatic spinning of the liquid matrix in electrostatic field between at least one spinning electrode and a collecting electrode positioned opposite thereto, while the spinning electrode contains at least one spinning member containing the cord, which comprises a straight section which is parallel with a plane of depositing the nanofibers and/or with the collecting electrode and it forms an active spinning zone of the cord. The cord of the spinning member is stationary or is displaceable in a direction of its length or is movable in a direction of its length either discontinuously or continuously and to the cord there is assigned a device for application of the liquid matrix on the cord in a direction of length of the cord.

Device for production of nanofibres through electrostatic spinning of liquid matrix

Method for spinning the liquid matrix () in electrostatic field between at least one spinning electrode () and against it arranged collecting electrode (), while one of the electrodes is connected to one pole of high voltage source and the second electrode is connected to opposite pole of high voltage source or is grounded, at which the liquid matrix () being subject to spinning is to be found in electrostatic field on the active spinning zone () of the cord () of the spinning means () of the spinning electrode (). The active spinning zone () of the cord during spinning process has a stable position towards the collecting electrode () and the liquid matrix () to the active spinning zone () of the cord is delivered either by application to the active spinning zone () of the cord or by motion of the cord () in direction of its length. The invention further relates to the device for production of nanofibres and to the spinning electrode (), whose active spinning zone () of the cord in the carrying body () of the spinning electrode () has a stable position and to the cord () there is assigned the device () for application of the liquid matrix () to the cord (), which is arranged in the carrying body () of the spinning electrode ().

Method for spinning a liquid matrix for production of nanofibres through electrostatic spinning of liquid matrix

The invention relates to the rotary spinning electrode of an elongated shape into the device for production of nanofibres through electrostatic spinning of polymer solutions comprising a pair of end faces, between them there are positioned spinning members formed by wire, which are distributed equally along the circumference and parallel with axis of rotation of the rotary spinning electrode, while the end faces are made of electrically non-conducting material and all the spinning members are mutually connected in a electrically conductive manner.
