Abstract (en)

[origin: EP3399077A1] A nozzle device for spinning comprising a nozzle, a polymer solution supply means that supplies a polymer solution to the nozzle and ejects the polymer solution from the nozzle tip, and a solvent vapor supply means that supplies a gas containing vapor of the same solvent as the solvent of the polymer solution at least to the vicinity of the polymer solution just ejected, and a spinning method using the nozzle device for spinning. Solidification of a spinning solution is prevented at the nozzle tip from which the spinning solution is ejected.
