  • Patent number: 9890475
    Abstract: The present disclosure relates to a method and a device for application of liquid polymeric material onto the active spinning zone of the cord of the spinning member of the spinning electrode, where the application means moving reversibly along the active spinning zone of the cord in the device for production of nanofibres through electrostatic spinning of liquid material in electrostatic field of high intensity between at least one spinning electrode and against it arranged collecting electrode. The liquid polymeric material is applied onto the cord around its whole circumference without any contact with gaseous environment in the spinning space, where the application means reversibly moves, whereas while the cord is leaving the application means the thickness of the layer of the liquid polymeric material is being reduced and immediately after leaving the application means the process of electrostatic spinning of the liquid polymeric material applied on the cord is started.

  • Patent number: 9279195
    Abstract: 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.

  • Patent number: 8231822
    Abstract: Method for spinning the liquid matrix (38) in electrostatic field between at least one spinning electrode (3) and against it arranged collecting electrode (4), 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 (38) being subject to spinning is to be found in electrostatic field on the active spinning zone (3100) of the cord (310) of the spinning means (31) of the spinning electrode (3). The active spinning zone (3100) of the cord during spinning process has a stable position towards the collecting electrode (4) and the liquid matrix (38) to the active spinning zone (3100) of the cord is delivered either by application to the active spinning zone (3100) of the cord or by motion of the cord (310) in direction of its length.

  • Publication number: 20110037202
    Abstract: The present disclosure relates to the method for spinning of polymer matrix in an electrostatic field induced in a spinning space between a spinning electrode and a collecting electrode, at which the polymer matrix is delivered from a matrix reservoir into the electrostatic field on surface of the spinning electrode or by the spinning elements of the spinning electrode, whose principle consist in that the temperature of the spinning electrode or spinning elements of the spinning electrode, and/or reservoir, and/or of polymer matrix is increased above the surrounding temperature by means of resistance heating. The disclosure further relates to the device for performing of this method.

  • Publication number: 20110033568
    Abstract: The principle of the present disclosure is the device for production of nanofibres through electrostatic spinning of polymer matrix in a spinning space, in which against each other there is positioned a collecting electrode and a spinning electrode, between which an electric field of high intensity is induced. Next to this, in the spinning space there is arranged at least one electrical device which is coupled with winding of a transformer (8, 11), which is insulated for high voltage, while the second winding of transformer (8, 11) is connected to the device for generating and/or evaluating of electric voltage pulses positioned outside the spinning space.
