What's the matter with the upper thread of the sewing machine always breaking?

1. The quality of the thread is not good, try another thread with better quality.

2. There is a problem with the sewing needle. If the broken place is around the needle, check to see if there is a burr in the eye of the needle. Generally, the needle has burrs, and the thread is easy to break.

3. If the direction on the sewing needle is wrong, the thread will break. The sewing needle has a direction, and one side is square, which faces inward. If the direction is wrong, the thread will also break.

4. It is usually a new sewing machine. If the workmanship is rough, there will be burrs where the thread passes, and the thread will break.

5. If the thread winder of the sewing machine is too tight, it will cause thread breakage. At this time, the thread winder should be loosened.

Precautions for use of sewing machine

Before using the sewing machine, you should first check whether the parts are in good condition and whether the rotation is flexible. Before use, each oil eye should be properly filled with oil, and oil should be added at any time during use.

When using a sewing machine, it is not advisable to wear gloves, and the distance between the hands and the needle must be more than 60 mm. The upper and lower threads must be even, and a certain speed must be mastered to prevent sticking hands. If there is a breakdown during use, it should be stopped immediately and used after troubleshooting. When the machine head needs to be disassembled during repair, be careful not to lose parts.
