Abstract
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.
Claims4
A nozzle device for spinning, comprising a nozzle, a polymer solution supply means for supplying a polymer solution to a nozzle to eject it from a nozzle tip, and a solvent vapor supply means for supplying a gas containing the vapor of the same solvent as a solvent of the polymer solution at least to the periphery of the polymer solution just ejected.
A method of spinning fibers containing a polymer, comprising a step of ejecting a polymer solution from a nozzle tip, wherein spinning is performed while supplying a gas containing the vapor of the same solvent as a solvent of the polymer solution at least to the periphery of the polymer solution just ejected.
