The thread breaks in the sewing machine can be caused by the following situations. In the first case, the quality of the thread is not good. We generally use 402 special sewing thread for sewing. If you buy some inferior sewing thread, you may encounter frequent thread breakage. Try another line, maybe your problem will be solved.
The second case is that you still use that kind of thin sewing thread when sewing the clothes. We know that there are several types of sewing threads. For example, the thread for sewing jeans is thicker, while for sewing summer fabrics, georgette, silk Such lines are a bit thinner. If you use fine thread to sew the fabric, the thread will break. In such a situation, adjust the matching relationship between your fabric and thread.
There is also a problem with the sewing needle. If you buy a new needle and the needle eye has burrs, the thread will break easily, and the broken place is around the needle. In such a situation, we will change the sewing needle.
If the direction of the sewing needle is wrong, the thread will break, but if we take a closer look at the sewing needle, it has a direction. One side is square, and that is facing in. If you go in the wrong direction, there will be disconnection. The solution is to adjust the needle of the sewing machine, follow the regular needle method, with the square side facing inward, and then tighten the screw.
Except that the upper thread will break, the bottom thread will also break. If the bottom thread is broken, we will take out the bottom shuttle and adjust the upper screw. Generally speaking, it will be tight to cause the thread to break. We only need to loosen the screw slightly. When adjusting, you need to fine-tune it little by little. After the adjustment is done, the thread should be pulled out by pulling it, not too loose or too tight. You can experiment with this yourself and try it slowly.
If the sewing machine is not used for a long time, some parts will be rusty and the thread will be broken. Then we need to add some special sewing machine oil to the sewing machine at this time, so that the parts can rotate flexibly.
If the thread winder of the sewing machine is too tight, it will also cause the thread to break. At this time, we have to loosen the winder. The disconnection can be resolved.
Usually it is a new sewing machine. If the workmanship is rough, there will be burrs in the place where the thread passes, and the thread will break. We can observe carefully. If there is a broken thread caused by the burr, we need to use fine sandpaper. It is flat and smooth.
