<p>PROBLEM TO BE SOLVED: To provide a wet spinning apparatus for producing fiber yarn having small cross-sectional shape unevenness and size unevenness while suppressing temperature unevenness of spinning dope and a method for producing fiber.SOLUTION: A spinning apparatus for discharging spinning dope from a discharge hole of a nozzle pack into a coagulated liquid F is a wet spinning apparatus to which a supply pipe 5 for supplying the spinning dope to the nozzle pack is connected, and in which a discharge face 2 at a discharge side having the discharge hole is in contact with the coagulated liquid F and other part of the nozzle pack and the spinning dope supply pipe 5 are not in contact with the coagulated liquid F due to a seal box 1. The seal box 1 has such a shape that width thereof becomes wide at a part and narrow in a direction from the discharge face 2 to the spinning dope supply pipe 5.</p> |
