Embroidery is a beautiful art, but nothing is more frustrating than constant thread breaks in the middle of a project. Whether you're a beginner or a seasoned pro, understanding the root causes can save you time, reduce frustration, and improve the quality of your work. Here are some common reasons for thread breakage on embroidery machines and how to fix them.
1. Needle Installed Backward
One of the most overlooked issues is installing the needle incorrectly. The scarf of the needle (the small groove near the back) should always face backward, while the smooth part of the needle eye (hole) should face forward. Installing the needle incorrectly can disrupt the stitch formation, leading to frequent thread breaks.
How to Fix It:Double-check the needle orientation when installing it. Refer to your embroidery machine manual if you're unsure.
2. Incorrect Needle Size or Type
Using the wrong needle for your fabric and thread can also cause breakage. A needle with an eye that’s too small for the thread will create unnecessary tension, while the wrong needle type might not penetrate certain fabrics smoothly.
How to Fix It:
Use the correct needle size and type for your thread and fabric. For example:
Size 75/11 needles work well with most embroidery threads.
Use ballpoint needles for knits and sharp needles for woven fabrics.
If you're unsure, consult the needle guide provided with your embroidery machine.
3. Tension Issues
Improper thread tension is a frequent culprit for thread breaks.
Top Thread Tension: If the top thread tension is too tight, it can cause the thread to snap.
Bobbin Thread Tension: If the bobbin tension is too tight, it can pull excessively on the top thread, leading to breakage.
How to Fix It:
Adjust the top thread tension by following your machine’s tension guide.
For bobbin tension, use a screwdriver to loosen the bobbin case screw slightly if it’s too tight. Ensure it’s not too loose, though—just enough for smooth stitching.
4. Old or Poor-Quality Thread
Thread that’s old, brittle, or of poor quality tends to break easily. Over time, thread can dry out or degrade, especially if it’s stored in direct sunlight or a humid environment.
How to Fix It:
Invest in high-quality embroidery thread. Polyester threads tend to be more durable than rayon threads.
Store thread in a cool, dry place away from sunlight.
5. Needle Is Dull or Damaged
Needles don’t last forever. A dull, bent, or damaged needle won’t pass through fabric smoothly, creating excess stress on the thread and causing it to break.
How to Fix It:Replace the needle regularly, especially after completing large projects or when working with tough fabrics like denim.
6. Thread Path Issues
If the thread is not correctly threaded through the machine’s path, it can snag or catch on rough spots, leading to breakage.
How to Fix It:
Re-thread the machine from scratch, making sure the thread passes through all the guides, tension discs, and the take-up lever correctly.
Check for any rough spots or burrs along the thread path and address them.
7. Poorly Maintained Machine
A dirty or poorly maintained embroidery machine can cause thread breakage. Dust, lint, or small thread pieces stuck in the tension discs or bobbin area can interfere with smooth thread flow.
How to Fix It:
Clean your machine regularly, focusing on the bobbin case, thread tension discs, and needle plate area.
Oil your machine as per the manufacturer’s instructions.
8. Incorrect Fabric Stabilizer
Using the wrong type or insufficient stabilizer can cause the fabric to move excessively, creating tension on the thread and resulting in breakage.
How to Fix It:Choose the correct stabilizer for your fabric:
Tear-away stabilizer for woven fabrics.
Cut-away stabilizer for knits and stretchy fabrics.
Water-soluble stabilizer for delicate fabrics like lace.
9. Incorrect Bobbin Thread
Using incompatible or poor-quality bobbin thread can also cause breakage.
How to Fix It:
Use embroidery-specific bobbin thread that matches the weight and type of your top thread.
Ensure the bobbin is wound evenly and inserted correctly.
10. Improper Hooping Technique
If the fabric is not hooped tightly enough, it can cause the material to shift during embroidery, pulling on the thread and causing breaks.
How to Fix It:
Hoop the fabric tightly, ensuring it’s taut but not stretched.
Avoid over-tightening the hoop, as this can distort the fabric.
Final Thoughts
Thread breaks on embroidery machines can be frustrating, but they’re often preventable with proper setup and maintenance. By ensuring your needle is installed correctly, using the right needle and thread, adjusting tension, and maintaining your machine, you can significantly reduce thread breakage.
