Abstract
PURPOSE: To obtain polyester fibers having physical properties enough for practical use and pilling resistance only by the spinning step, by taking off melt extruded specific ethylene terephthalate polyester chips at a high speed.
CONSTITUTION: Polyester chips, consisting of a polyester containing ethylene terephthalate as principal repeating units, and having an intrinsic viscosity [η]≥0.5, preferably 0.6W1.0, and a moisture content ≥0.01wt%, preferably 0.03W0.10wt%, are melt extruded and taken off at a high speed ≥6,000m/min and spun to give the aimed fibers.
