What is the Tension in a Sewing Machine?

Before we jump to the tutorial, let’s know what is the tension in the sewing machine. The stitch tension or thread tension is the amount of pressure on the thread that passes through the machine to produce stitches. Sewing or stitching quality on a fabric depends a lot on the tension. Higher pressure on the thread will produce loose stitch.

Besides, lower pressure on the stitch will produce a tighter stitch. The sewing tension can be easily altered using the built-in dial on your sewing machine. The dial should be in the right position to produce the perfect stitch along with other factors.

How does Tension work?

There are two types of tension in the sewing machine which are top thread tension and bottom thread tension. Most of the sewing machines feature two metal discs on the top to utilize the top tension. You can control the thread using the dial on the machine. There is a spring that will adjust the thread when you turn the dial.

If you turn the machine two the increment of the number, then the tension of the machine will increase. You can decrease the tension by doing the opposite. Though in most of the machines you will require manually adjusting the tension, some sewing devices may adjust the tension automatically.

Make sure that the presser foot is raised when you are adjusting the sewing tension. Another type of tension is called bottom tension which is also known as bobbin tension. The tension can be adjusted by tweaking a screw on the bobbin case. You will usually don’t require adjusting the bobbin tension that much.

When Do You Require Adjusting the Tension?

The sewing tension doesn’t require frequent adjustment. You will only need to alter the top tension if the top thread tension alters somehow. Such as, it can happen while changing the thread weight from heavy to low. You may also require changing the tension when your thread material or brand is changed.

You will also need to adjust the top thread tension if the bobbin stitches are visible on the top of the fabric. If you think that the top thread is properly adjusted, then it can happen for the weak threads from the bobbin.

Sometimes, the needle threads can be visible on the bottom of the fabric when the bottom thread is tightening much. However, it can also happen for the weak threads that arrive from the top. In both of the situations, you will need to correctly adjust both tensions following the user manual.
