Abstract

PURPOSE: A mixture of an olefin resin and a foaming agent is melt extruded under specific conditions, thereby preventing the accumulation of scales on the die near the outlets of molten polymer without any adverse effect on the quality of foamed and opened yarns.
CONSTITUTION: A foaming polymer is melt extruded from slit of ring die 1 in cylindrical form, drafted and taken off under foaming and opening wherein heating elements 2a is also set near outlet 1a of the molten polymer on ring dice 1 and preferably ring 4a for flowing cooling air is set in such a way to surround bubble 5. Thus cooling air is blown toward the place near molten resin outlet 1 on the die preferably under conditions controlled to 0W50°C in temperature and to 3W20 m/sec in blowing speed.
