Abstract

See full text

A fiber manufacturing method includes the following steps of: dissolving a polymer in a solvent to obtain a polymer solution; spraying the polymer solution into a liquid heated to a boiling point of the solvent or higher, and evaporating the solvent to precipitate a fibrous polymer in a sealed precipitation tank, the liquid being immiscible with the polymer and the solvent; conveying the precipitated fibrous polymer in a liquid from the precipitation tank; water-rinsing the fibrous polymer conveyed in the liquid in the conveying step in a sealed water-rinsing tank; conveying the water-rinsed fibrous polymer in a liquid from the water-rinsing tank; and cooling and condensing solvent gas that is generated in the spraying step and the water-rinsing step.
