METHOD AND APPARATUS FOR MANUFACTURING SYNTHETIC FILAMENT FROM SPINNING SOLUTION BY MEANS OF WET SPINNING

摘要

PURPOSE: To obtain a synthetic filament excellent in coloring capability, speed and uniformity, and having a good processing property by setting a ratio of the spinning speed of a bath accompanying the filament and the speed of the spun filament in a prescribed range. CONSTITUTION: This method for producing a synthetic filament from a spinning solution by a wet spinning method of introducing a (part of) spinning bath into a spinning tube so as to accompany with the filament, comprises setting a ratio of the speed of the spinning bath accompanying with the filament (bath speed) and the speed of the spun filament (filament taking out speed) in 0.15-0.95 range value to obtain an objective synthetic filament.
