Abstract

The invention relates to a method of producing nanofibres from polymer solutions by electrospinning process in which spinning elements from non-metallic, electrically non- conductive materials having a ragged surface are used. Advantageously, during the spinning process, the spinning elements sink gradually in the lengthwise direction into the spinning solution, come gradually out of the solution and enter gradually an electric field. During the electrospinning process, the shape of the layer of the spun polymer solution adhered to the spinning elements is modified locally and formation of Taylor cones necessary for the proper process of the nanofibres formation is stimulated. Further, the invention concerns the spinning elements for carrying out the above method, the said spinning elements being manufactured from non-metallic, electrically non-conductive materials having a rugged surface and positioned in the carrying elements so that they are oriented in the direction oblique to the surface of the spinning solution.
