Abstract
PURPOSE: Dry or wet spinning is conducted by using spinnerets having groups of nozzles different in diameter to produce efficiently continuous acrylonitrile filament yarns contining filaments different in denier from each other that can be uniformly dyed and have soft and elastic feeling.
CONSTITUTION: A dope of acrylonitrile polymer is extruded through spinnerets which have three groups, A, B, and C of nozzles different in diameter from each other into the air or another inert gas atmosphere and immediately introduced into a coagulation bath to form fibers. The ratios of nozzle deameter and nozzle number of each group are selected so that the denier ratio of the resulting mixed may be A:B:C=1.5:1.3:1W18:8:1, the nozzle number ratio may be A:B:C=(1W12): (1W12):(2W25) and preferably the number of nozzles with large diameter may be lessened
