Document Type and Number:
Japanese Patent JPWO2006001324
Kind Code:
A1
Abstract:
A spinning pack for dry-wet spinning is provided with a spinneret having not less than 6,000 spinning holes and having an aspect ratio Ra of not less than 2.5 for a spinning hole array of the spinning holes. In a device and method for producing a fiber bundle, a drawing angle of single fibers formed by the single fibers and a spinneret surface of a spinneret is in a range from 87° to 92°, the single fibers being fibers discharged from the outermost spinning holes located in the long side direction of the spinneret and running to a fiber bundle diverting guide provided in a coagulation bath. Further, a drawing angle of single fibers formed by the single fibers and the spinneret surface of the spinneret is in a range from 83° to 87°, the single fibers being fibers discharged from the outermost spinning holes located in the short side direction of the spinneret and running to the fiber bundle diverting guide provided in the coagulation bath.
