Abstract: PROBLEM TO BE SOLVED: To solve the problem that the mechanical characteristics such as strength of fiber obtained at a higher winding speed than conventional speeds deteriorate, and the draw ratio is lowered and remarkable improvement in productivity can be attained when fiber spinning is performed at a higher spinning speed than conventional in a direct spinning and drawing process.
