PURPOSE:To prevent the clogging of nozzle or generation of fine filament even after the repeated use of a spinneret, and to improve the stability of operation, by carrying out the mixing and spinning of plural polymers using a mixed spinning nozzle pack furnished with a specific static mixer. CONSTITUTION:Separately melted and supplied polymers A, B such as polyester, polyamide, polyethylene, etc. are introduced into a nozzle pack for mixed spinning. The pack is furnished with two or more polymer-feeding parts (polymer- introducing holes 1A, 1B) and static mixers 4, 5, 6 divided into >=2 stages containing 1-3 elements each. The polymers are mixed in the pack, and extruded through the nozzle 8 of the nozzle plate 7. Stable operation can be carried out by this apparatus without causing the nozzle clogging and the generation of fine filament.
