How to solve the stitch problem of sewing machine1

If we are usingIf there is a problem with the stitches during the sewing process of the electric sewing machine, then it is necessary to focus on checking the thread clamp and the hook, because they are the components that control the tension of the upper thread and the lower thread. The tightness of the bottom line. There are four main types of stitching problems:

Floating upper thread: The tension of the upper thread is too large, or the tension of the bottom thread is too small. The bottom thread is pulled to the top of the sewing material by the upper thread, and the upper thread has a raised phenomenon. The solution: adjust the thread clamp to reduce the tension of the upper thread. Or adjust the hook to increase the tension of the bottom thread

Floating bottom thread: The tension of the upper thread is too small, or the tension of the lower thread is too large, the upper thread is under the sewing material by the lower thread, and the lower thread is raised. The solution: increase the tension of the upper thread.

Or adjust the hook to reduce the tension of the bottom thread

Loose and floating stitches: In this case, the tension of the upper thread and the lower thread may be too small. The solution: properly adjust the tension of the upper thread and the lower thread through the thread gripper and the hook.

Wrinkled fabric: This is where the tension on both the upper and lower threads is too high. Solution: Reduce the tension of the upper thread and the lower thread through the thread clamp and the rotary hook.
