Abstract
A process for producing purified polysaccharide fiber of the present invention includes bringing a polysaccharide solution, which is obtained by dissolving a polysaccharide raw material in a liquid containing an ionic liquid, into contact with a solidification liquid containing an ionic liquid, and performing dry-wet spinning on polysaccharide, in which the concentration of the ionic liquid in the solidification liquid is 0.4% by weight to 70% by weight, and a distance D from a site where the polysaccharide solution is extruded in the form of fiber to a site where the extruded polysaccharide solution comes into contact with the solidification liquid is 50 mm to 120 mm.
