exact nature of the coating material and core yarn s used and the characteristics desired of the final product in addition the tension setup required to successfully weave the preferred yarn is different from pvc yarn in general tensions of the warp and fill yarns have been reduced to compensate for the increased yarn friction tackiness and tendency for particulate formation fill yarn winder position and brush position are adjusted to control tension the reduced tension prevents excessive fill yarn breakage thereby increasing loom production time additional measures are taken to improve the process for example the shed is timed to close later in the weaving cycle this reduces the tendency of shaving off the yarn 39 s coating the shed timing delay must however be carefully balanced because too much delay will result in an improper grip of the fill yarn by the warp yarn and will result in a kinky fill stop motion sensitivity is adjusted to prevent false fill stops cutouts placed behind fill yarn tubes on the creel prevent the yarn from looping behind the tube and breaking finally the lubricant application rate is carefully controlled so that the proper amount of lubricant is applied individual yarns that compose the fabric are bonded together in heat setting step 670 in this step the woven fabric is positioned on a finishing range preferably a babcock model.
