Combined spinning nozzle for manufacture of nanofibrous and microfibrous materials

摘要

The combined spinning nozzle for the production of nanofibrous or microfibrous materials according to the invention 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) as well as the first non-conductive body (2) may assume either plate-like or cylindrical shapes. The combined spinning nozzle may further comprise the second non-conductive body (4) adjoining the second wall of the thin-walled electrode (1) and directing the air from the proximal end towards the distal end (6) of the nozzle. The combined spinning nozzle is easy to dismantle and clean since the spinning capillaries assume the shape of the grooves (5) formed on the surfaces of the first or third non-conductive bodies (2 or 7 respectively).
