FIELD: materials.
SUBSTANCE: invention relates to production of superfine fibre materials for superfine filtration by electroforming methods from charged polymer solutions and method of filter material producing from polymer fibres without tissue substrates. Method involves deposition of substrate-base on movable, grounded, solid electrode, made of aluminium sheet with thickness of 10 cm with rounded edges. Protection of fiber-forming elements and reduction of corona discharges is performed by electronegative gas solvent vapors mixture, in particular, nitrogen purified from traces of oxygen.
EFFECT: invention ensures production of materials with high filtration characteristics, higher efficiency of filtering material forming process and reduced its fire hazard.
