The polyester may be contain up to 10% of repeat units derived from a C 3-6 alkylene glycol or diethylene glycol; and up to 20% of repeat units derived from terephthalic acid. The filament is drawn immediately after extrusion or after storing at a relative humidity of at least 65% and a temperature of 71-73‹ F; and heated during drawing by passing over a hot plate or snubbing pin at a temperature of at least 100‹ C. |
