most any type of synthetic filament yarn can be employed in the invention as long as it can be drawn generally the yarn employed is a polyamide polyester or polyolefin yarn however the use of other yarns is within the scope of the invention good results were obtained using polypropylene as the polyolefin yarn yarns processed according to the method and apparatus of the present invention are normally processed at a rate ranging from about 600 to about 1000 meters per minute to produce a drawn yarn having a twist ranging from about 0 1 to about 1 0 twists per inch tpi however rates ranging from about 800 to 900 meters per minute and a twist ranging from about 0 2 to about 0 8 tpi will probably be used most often it is recognized that twisting a yarn such as by employing a 2 for 1 twister and then drawing the twisted yarn is not a new process in the broad sense however such a process has been difficult to operate with feed yarns having a tenacity ranging from about 1 0 to 2 0 grams per denier satisfactorily because of filament breakage as is well known in the art as spun.
