FIELD: process engineering.
SUBSTANCE: invention relates to production of polymer micro fibrous filtration materials to be used for air cleaning, in particular, in individual respiratory apparatus protection means. In compliance with this invention, slectrospun of fibers from the melt solution consists in introducing salts of higher fatty acids into polymer melts. Content of said salts makes 1-10 wt %. Said polymers are selected from the series of polyolefines and polyethers or the mix thereof, or the mix of series of polyolefines, polyethers and polyamides.
EFFECT: higher physical and chemical properties.
