ABSTRACT:
Oriented polymeric monofilaments having a diameter of at least about 60 mils and excellent uniformity in roundness, are prepared in which a core of semi-crystalline linear condensation polymer is melt extruded, quenched to a substantially void-free condition, coated with additional polymer to increase the diameters by about from 10 to 100 mils, quenched to a substantially void-free condition, and oriented by drawing about 3.5 times its original length within the orientation temperature range of the polymer.
