Abstract
The combined spinning nozzle for the production of nanofibrous or microfibrous materials comprises a thin-walled electrode (1) and a first non-conductive body (2) adjoining the first wall of said thin-walled electrode, said first body having its wall, which faces the thin-walled electrode (1), provided with an array of grooves (5) formed therein, said grooves leading to the distal end (6) of the combined spinning nozzle and having their proximal ends connected to a supply of spinning mixture. The thin-walled electrode (1) and the first non-conductive body (2) may assume either plate-like or cylindrical shapes. The combined spinning nozzle may further comprise a second non-conductive body (4) adjoining a second wall of the thin-walled electrode (1) and directing the air from the proximal end towards the distal end (6) of the nozzle.
