Abstract
PURPOSE: To obtain yarns of high grade, by melt spinning a thermoplastic polymer through a spinneret, consisting of a sintered metal or wire netting, and heated itself while cooling the extruding surface to reduce the extruding pressure and improve the spinning property.
CONSTITUTION: In melt spinning a thermoplastic polymer through a spinneret 2 consisting of a sintered metal or wire netting, the extruding surface of the spinneret 2 is cooled while heating the spinneret 2 itself. The heating of the spinneret 2 may be carried out by the heat generation with the Joule heat with the current conduction of the spinneret 2, dielectric heating with high-frequency waves, etc. The cooling of the spinneret surface may be carried out by blowing cool air thereon.
