FIELD: chemistry.
SUBSTANCE: invention relates to a composition of a molding solution for producing nonwoven material by electroforming to achieve the required performance properties. Invention relates to composition of molding solution for producing vapour-permeable membrane, as well as control of complex of membrane material operational properties. Composition for producing a vapour-permeable porous membrane contains fluoroplastic F-42 and N, N-dimethylformamide, as well as polyurethane Elastollan 1164 D11 and butyl acetate in ratio of N, N-dimethylformamide and butyl acetate 1:1. When using material based on nanofibers from polyurethane elastollane 1164 D11 and fluoroplastic F-42, a number of properties are achieved, which make it possible to use material as a selective filter for protective clothing.
EFFECT: composition provides higher functional properties of membranes: vapour permeability and strength at tearing.
