a liquid cooled quench zone may also be suitable for use tension is applied to the fibers by means of a set of godets each comprising one or more reels which may or may not be heated engaging the fibers and operating at different speeds to thereby stretch the fiber the difference in surface velocity in the godets subsequent godets operating at higher velocities determines the spin draw ratio or drawdown of the fibers that is a spin draw ratio of 100 1 indicates the use of a final surface velocity of the godet that is 100 times faster than the extrusion rate of the spinnerette and consequently a fiber cross sectional area 100 times smaller than the cross sectional area of the fiber as extruded after exiting the godet the fibers are cooled to ambient temperature less than 140 u00b0 c preferably less than 100 u00b0 c and collected on a take up reel or other fiber collection device or optionally subjected to redrawing the fibers are redrawn in order to impart further strength properties redrawing may be performed at temperatures less than 140 u00b0 c cold redrawing or performed after first reheating the fiber to a temperature from 140 u00b0 to 250 u00b0 c hot redrawing hot redrawing is the preferred redrawing technique preferred redrawing ratios are as high as 10 1 preferably from 2 0 1 to 5 1 meaning a further reduction of cross sectional area before and after redrawing corresponding to the stated ratio after redrawing the fibers are again cooled to ambient temperature and may again be collected on a take up reel or other fiber collection device the skilled artisan will appreciate that the invention disclosed herein may be practiced in the absence.
