Upper Thread Tension

► Upper Thread Tension
The upper thread tension is optimally set in the factory.
Depending on the brand of sewing thread, variations in upper thread tension may occur. You can override the default setting based on thread and fabric you are using in the Upper Thread Tension in the Sewing Settings. This modification is made to all sewing patterns and kept until changed again in the Settings, even after a machine restart.
The higher the upper thread tension, the more the upper thread is tensioned and the bobbin thread is pulled more strongly into the fabric. The lower the upper thread tension, the less the upper thread is tensioned and the bobbin thread is pulled less strongly into the fabric.
| Perfect Stitch Formation The thread knotting is in the center of the fabric. |
| Upper thread tension too tight This pulls the bobbin thread more strongly into the fabric. |
| Upper thread tension too loose This pulls the upper thread more strongly into the fabric. |
Tip
If the sewing test shows that the upper thread tension is not optimal for a stitch pattern, you can modify the upper thread tension for the selected stitch pattern using the Upper Thread Tension function in the status bar.
