FIELD: process engineering.
SUBSTANCE: invention relates to production of polymer fibrous filtration materials and covers the method of electroforming 1-10 mcm diametre fibers from 5% to 20% by weight of polymer solution in organic solvent that features viscosity of 3.5 to 5.0 p at electroforming voltage of 60 to 140 kV. In compliance with this method, the used polymer used represents chlorinated polyethylene or polypropylene with chlorination of 64-66% and molecular weight of (2-15) 105. Material, thus produced, is used for protection of respiratory system when applied on dressed gauze substrate.
EFFECT: higher protective properties.
