FIELD: manufacture of substantially endless thin threads from polymer solutions, in particular, lyocellulose textile masses.
SUBSTANCE: method involves forming textile mass flowing from at least one forming aperture or forming slot; drawing formed thread or film by means of gas flow accelerated to high speed by means of Laval nozzle, whose narrowest section is arranged downstream of textile mass exit end; delivering threads onto tape formed as non-woven material or gripped in the form of yarn and separated from solvents in settling tanks.
EFFECT: improved method and apparatus for manufacture of endless thin threads and film, which are not damaged by thermal action of gas flows used for drawing thereof.
