Abstract

The article deals with an experiment that was carried out on a test spinning device designed for the production of nanofibres by electrostatic spinning from a string. In the experiment, a spinning device was created in the form of a vertical stringed moving electrode. This was rewound between two coils and a polymer solution was continuously delivered to the electrode surface by a special dosing device. The intensity of the electric field and the distance of the Taylor cones. Nozzles from which emerging nanofibers travel to the collector, depend on the different cross sections of the strings used. The aim of the experiment was to find critical voltage for different strings. Critical voltage is one in which the spinning process starts. This value is very important as it creates a requirement for a minimum supply voltage. The work selects and points out to different cross-sections of the strings and the corresponding distance of the Taylor cones.
