METHOD FOR PRODUCING ACRYLIC FIBER AND APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus capable of eliminating the breakage of a yarn, and capable of improving the productivity by improving the spinning speed without using a complicated operation or apparatus. SOLUTION: This method for producing an acrylic fiber is characterized in that when producing the acrylic fiber by wet spinning, the tension of fiber bundle is reduced in a coagulation bath. The apparatus for producing the acrylic fiber has a guide means installed for passing the fiber bundle in a meandering state in the coagulation bath.
