Drawing POY yarn by mechanical and thermal conditions and winding it on beams. 


Draw warping is a term used in correlation with weaving beams only. Draw warping connotes the drawing ("stretching") of POY yarn as well as winding the yarn parallel on beams - whereas this all happens on one machine.


The feedstock for draw warping is extruded POY yarn that is wound on spools (normally around 800 to 2000 ends) and put on a creel. Said yarn is then pulled off the spools and led through rolls that preheat and draw the yarn. The yarn goes then on a heat plate which fixates the drawing / orientation of the yarn. Finally, the yarn passes through cooling rools and is being wound on the warp beam.
