Abstract
PURPOSE: A non-heating chimney is provided under the spinneret instead of a heating chimney and the temperature in the chimney is adjusted to that of the polymer preheating, thus preventing the disturbance of the air in the chimney and producing undrawn yarns having good drawability.
CONSTITUTION: A thermoplastic resin as polyethylene terephthalate is melt spun wherein a non-heating chimney 3 is provided under the spinneret to adjust the temperature of the atmosphere in the chimney to that of the preheated polymer in the spin block 1. The temperature is detected with detecting terminal T3 in the non-heating chimney 3 and controlled by controller C and the polymer is preheated with heater H1.
