  • Patent number: 10808334
    Abstract: The invention relates to a spinning electrode (1) for producing polymeric nanofibers by electrospinning of a polymer solution or polymer melt, containing an inlet pipe (2) of the polymer solution or melt, which ends on its top face (3), whereby around at least a part of the mouth (20) on the top face of the inlet pipe (2) of the polymer solution or melt is formed a spinning surface (4) rounded downwards below the mouth (20), whereby the spinning surface (4) continues as a collecting surface (6) on the outer surface of the inlet pipe (2) of the polymer solution or melt. The invention also relates to a device for producing nanofibers by electrospinning of a polymer solution or melt, which is equipped with at least one spinning electrode (1) according to the invention. In addition, the invention relates to a method for producing nanofibers by electrospinning of a polymer solution or melt, which is based on using the spinning electrode according to the invention.

  • Publication number: 20180355521
    Abstract: A method, system, and resulting linear fibrous formation are provided wherein a supporting linear formation defines a core that is transported through a spinning chamber. A coating of polymeric nanofibers enveloping the supporting linear formation in the spinning chamber. The coating of polymeric nanofibers comprises a flat stripe wound around the core into a helical form, the flat stripe created from a hollow electrically neutral nanofibrous plume generated in a spinning space above a spinning electrode during spinning by AC electric voltage in the spinning chamber.

  • Patent number: 10041189
    Abstract: The invention relates to a method for production of polymeric nanofibers, in which polymeric nanofibers are created due to the action of force of an electric field on solution or melt of a polymer, which is located on the surface of a spinning electrode, whereby the electric field for electrostatic spinning is created alternately between the spinning electrode (1), to which is supplied alternating voltage, and ions (30, 31) of air and/or gas generated and/or supplied to proximity of the spinning electrode (1), whereby according to the phase of the alternating voltage on the spinning electrode (1) polymeric nanofibers with an electric charge of opposite polarity and/or with segments with an electric charge of opposite polarity are created, which after their creation cluster together under the influence of the electrostatic forces into linear formation in the form of a tow or a band, which moves freely in space in direction of gradient of the electric fields away from the spinning electrode (1).
