When producing polyester sewing thread, it is inevitable that there will be a problem of polyester sewing thread jumper . So what about polyester sewing thread jumper ? The phenomenon of jumpers occurs especially during the stitching process. To avoid this phenomenon, once again, as a front-line production operator should check whether the quality of the polyester thread is qualified, is there any mold or deterioration? 1. We have to check if the selected polyester thread is matched with the needle. The polyester thread is too fine because the toughness is insufficient, it will easily break. The needle is too thick for the sewing thread, which will make the polyester thread have no way. The passage was cut off. 2, the needle problem is also we should pay attention to, check whether there is a phenomenon because the needle heat fuses the seam, especially when using the fiber, because the machine is running at high speed, the needle repeatedly inserts the fabric to friction and heat, making The chemical fiber having a lower melting point is melted. 3. Another problem is to check if the bobbin thread is too full or the winding is not uniform. If the bobbin is too slow or uneven, it will not be very smooth during the transportation. In addition, the operator's gesture is not good. Or the speed of the car without the rhythm will cause the polyester sewing thread to be cut. Please indicate the source.
