发明名称	MELT-SPINNING SPINNERET PACK
摘要	<P>PROBLEM TO BE SOLVED: To provide a melt-spinning spinneret pack free from generation of quality difference of shape and physical properties of each filament constituting a multi-filament, and suitable for spinning a multifilament especially having low dtex by a method of blowing a straightened cooling air flow from the outer circumference toward the center side by using a cylindrical cooling air blower. Ž<P>SOLUTION: In the melt-spinning spinneret pack, a molten thermoplastic polymer supplied into a spinneret pack 1 is expanded F<SB>2</SB>, and filtered while keeping the expanded state to filter foreign materials in the polymer, the filtered polymer is joined together at a part while constricting the flow at a joining part F<SB>3</SB>formed at the center of the pack, round tubular polymer flow paths F<SB>4</SB>are arranged with equal spaces in a manner expanding on the downstream from the top including the outlet of the polymer injected from the joint part, the polymer is distributed to nozzle groups H equally distributed on a circular center line formed of the equally distributed polymer flow paths, and the multifilament is spun from the nozzle groups.
