advanced to the two stage draw zone via rolls 25 and 26 which may be heated or non heated in the first draw stage yarn 31 is drawn between feed roll 28 and draw roll 29 at a draw ratio within the range of about 1 01 and about 2 drawn yarn 32 is then subjected to a second draw at a draw ratio at least about 2 2 times the first draw ratio preferably a draw ratio within the range of about 2 2 to about 3 4 times that of the first draw the temperature of roll 28 is less than about 100 u00b0 c the temperature of draw roll 29 is within the range of about 50 to about 150 u00b0 c the temperature of draw roll 30 is within the range of about 100 to about 200 u00b0 c drawn yarn 33 is advanced to heated rolls 34 and 35 to preheat the yarn for texturing yarn 36 is passed through texturing air jet 37 for bulk enhancement and then to jet screen cooling drum 38 textured yarn 39 is passed through tension control 40 41 and 42 and then via idler 43 to optional entangler 44 for yarn entanglement if desired for better processing downstream entangled yarn 45 is then advanced via idler 46 to an optional spin finish applicator 47 and is then wound onto winder 48 the yarn can then be processed by twisting texturing and heat setting as desired and tufted into carpet as is known in the art of synthetic carpet manufacture poly trimethylene terephthalate.
