Claims (4)

1. Форсуночное устройство для формования волокон, содержащее форсунку, средство подачи раствора полимера для подачи раствора полимера к форсунке для его выпускания из наконечника форсунки, и средство подачи пара растворителя для подачи газа, содержащего пар того же растворителя, что и растворитель указанного раствора полимера, по меньшей мере к периферии только что выпущенного раствора полимера.1. A nozzle device for forming fibers, comprising a nozzle, means for supplying a polymer solution for supplying a polymer solution to the nozzle for its discharge from the nozzle tip, and means for supplying a solvent vapor for supplying gas containing steam of the same solvent as the solvent of said polymer solution, at least to the periphery of the newly released polymer solution. 2. Форсуночное устройство для формования волокон по п. 1, которое имеет двухтрубчатую часть конструкции, образованную из внутренней трубки, которая является форсункой, и окружающей ее наружной трубки, причем указанная двухтрубчатая часть конструкции выполнена таким образом, что газ, содержащий пар того же растворителя, что и растворитель указанного раствора полимера, подается из пространства между внутренней трубкой и наружной трубкой.2. The nozzle device for forming fibers according to claim 1, which has a two-tubular part of the structure formed from the inner tube, which is the nozzle, and the outer tube surrounding it, and the specified two-tubular part of the structure is made in such a way that a gas containing steam of the same solvent that the solvent of the specified polymer solution is supplied from the space between the inner tube and the outer tube. 3. Способ формования волокон, содержащих полимер, включающий стадию выпускания раствора полимера из наконечника форсунки, в котором формирование волокон выполняют одновременно с подачей газа, содержащего пар того же растворителя, что и растворитель указанного раствора полимера, по меньшей мере к периферии только что выпущенного раствора полимера.3. A method of forming fibers containing polymer, comprising the step of releasing the polymer solution from the nozzle tip, in which the formation of fibers is performed simultaneously with the supply of gas containing steam of the same solvent as the solvent of the specified polymer solution, at least to the periphery of the just released solution polymer. 4. Способ формования волокон по п. 3, в котором газ, подлежащей подаче, содержит вещество, которое в условиях во время формования волокон находится в газообразной фазе и насыщено паром того же растворителя, что и растворитель указанного раствора полимера.4. The method of forming fibers according to claim 3, in which the gas to be supplied contains a substance which, under conditions during the formation of the fibers, is in the gaseous phase and is saturated with steam of the same solvent as the solvent of said polymer solution.
