PROBLEM TO BE SOLVED: To provide a spinning bath apparatus for an acrylic fiber bundle, with which a single filament breakage is essentially prevented simply at a low cost. SOLUTION: The spinning bath apparatus comprises a coagulating liquid bath, a spinning nozzle that is sunk in a coagulating liquid and discharges an acrylic polymer solution to the coagulating liquid, a coagulating liquid discharge hole that is positioned in the direction opposite to the discharge direction of the acrylic polymer to the spinning nozzle on the bottom of the coagulating liquid bath and discharges a coagulating liquid approximately in the vertical direction to the raising direction of a coagulated yarn, an overflow port that is arranged at the top of the coagulating liquid bath and pours an excessive coagulating liquid in the raising direction of the coagulated yarn and a grooved guide roller with which the coagulated yarn discharged from the spinning nozzle is firstly brought into contact except the coagulating liquid. The groove bottom part of the lower peripheral surface of the grooved guide roller is positioned at a distance 0-30 mm above the coagulating liquid level. COPYRIGHT: (C)2006,JPO&NCIPI
