Why Does Thread Keep Breaking While Sewing? Causes and Solutions

Thread breaking while sewing is one of the most common problems, whether you are a beginner or an experienced sewer. Not only is it frustrating, but it also slows down the sewing process and affects the final result.

In most cases, broken thread is not caused by a damaged sewing machine. It usually comes from small technical issues that often go unnoticed.
In this article, we will discuss the reasons why thread keeps breaking while sewing and how to fix them.

Causes of Thread Breaking While Sewing

1. Thread tension is too tight

One of the most common causes is thread tension that is set too high. When the thread is pulled too tightly, it does not have enough flexibility and eventually snaps, especially when sewing thick or layered fabrics.
The solution is to lower the tension gradually until the stitches run smoothly.

2. The thread is not suitable for the fabric

Using thin thread for thick fabric, or low-quality thread for heavy sewing, can easily cause the thread to break. Use stronger thread for fabrics like denim or canvas, and standard thread for lighter fabrics such as cotton or rayon.

3. The needle is dull or damaged

A dull, bent, or chipped needle can damage the thread during sewing. The thread continuously rubs against the needle until it eventually breaks.
Replace your needle regularly, especially after sewing thick fabrics or if the needle has been used for a long time.

4. Needle size does not match the thread

If the needle is too small for a thick thread, the thread will be squeezed in the needle eye. This causes excessive friction and makes the thread wear out and break easily.
Make sure the needle size matches the thickness of the thread you are using.

5. Incorrect threading path

When the thread is not placed correctly through the machine’s threading path, the tension becomes uneven. This often happens when threading the machine in a hurry.
When threading, make sure the presser foot is lifted so the thread sits properly in the tension discs.

6. Dirty and poorly maintained sewing machine

Lint, dust, and fabric residue that build up around the bobbin area and thread path can create extra friction, causing the thread to break more easily.
Clean your sewing machine regularly, especially around the needle plate and bobbin area.

7. Sewing at very high speed

Sewing too fast, especially on thick fabrics or detailed areas, can cause the thread to be pulled suddenly and snap.
Try reducing your sewing speed and work more steadily for better and safer results.

How to Prevent Thread from Breaking While Sewing

Here are some simple steps you can follow:
* Use good quality thread
* Match the thread, needle, and fabric properly
* Adjust the thread tension correctly
* Replace needles regularly
* Keep your sewing machine clean

Conclusion

Thread breaking while sewing can be annoying, but it is not a serious problem if you understand the causes. With proper tension settings, the right choice of thread and needle, and regular machine maintenance, sewing can become much smoother and more enjoyable.
For sewing beginners, understanding basic issues like this is an important step toward achieving neat stitches and keeping sewing tools in good condition.
