Why Your Sewing Machine Keeps Cutting Thread And What You Can Do About It
What To Know
- The rhythmic hum of a sewing machine can be both soothing and productive, but that harmonious symphony can quickly turn into a frustrating cacophony when the machine starts cutting thread.
- Burrs or rough edges on the thread path, such as the bobbin case or needle plate, can snag the thread and cause it to cut.
- If the thread is not properly threaded through the machine, it can create tension and cause the thread to snap.
The rhythmic hum of a sewing machine can be both soothing and productive, but that harmonious symphony can quickly turn into a frustrating cacophony when the machine starts cutting thread. This common issue can disrupt your sewing projects and leave you scratching your head. In this comprehensive guide, we will delve into the reasons why sewing machines cut thread and provide solutions to help you troubleshoot and resolve the problem.
Causes of Thread Cutting
1. Incorrect Thread Tension:
- Too much tension can cause the thread to snap when it is pulled through the machine.
- Adjust the tension dials on the machine to ensure the thread is flowing smoothly without excessive tightness.
2. Dull or Damaged Needle:
- A dull or damaged needle can create friction and cause the thread to break.
- Replace the needle with a sharp, new one to eliminate this problem.
3. Burrs or Rough Edges on Machine Parts:
- Burrs or rough edges on the thread path, such as the bobbin case or needle plate, can snag the thread and cause it to cut.
- Inspect the machine for any imperfections and smooth out any rough edges with a fine-grit sandpaper or a needle file.
4. Poor Thread Quality:
- Low-quality thread is more prone to breaking and fraying.
- Use high-quality thread designed for sewing machines to minimize thread cutting issues.
5. Improper Threading:
- If the thread is not properly threaded through the machine, it can create tension and cause the thread to snap.
- Follow the threading instructions carefully and ensure the thread is guided correctly through all the guides and tension discs.
6. Overheating:
- Excessive heat generated by the machine can weaken the thread and make it more susceptible to cutting.
- Allow the machine to cool down periodically and avoid sewing for prolonged periods without breaks.
7. Bobbin Tension Too Loose:
- The bobbin thread should be slightly taut to prevent it from becoming loose and tangling with the upper thread.
- Adjust the bobbin tension screw to ensure the thread is snug but not excessively tight.
Troubleshooting Tips
1. Check the Thread: Examine the thread for any nicks, fraying, or weakness. Replace it with a new spool if necessary.
2. Inspect the Needle: Look for any damage or dullness on the needle. Replace it with a sharp, new needle of the appropriate size and type.
3. Clean the Machine: Remove any lint, dust, or debris that may be causing friction and snagging the thread.
4. Adjust the Tension: Refer to the machine’s manual for the recommended tension settings and adjust the dials accordingly.
5. Check the Thread Path: Ensure the thread is correctly threaded through all the guides and tension discs without any obstructions.
6. Lubricate the Machine: Apply a small amount of sewing machine oil to the moving parts to reduce friction and prevent overheating.
7. Use a Thread Conditioner: A thread conditioner can help lubricate the thread and prevent it from breaking.

Frequently Asked Questions
Q: Why does my sewing machine cut thread when I sew thick fabric?
A: Thick fabrics require a stronger needle and thread. Use a heavy-duty needle and a thicker thread designed for sewing heavy materials.
Q: How do I prevent my sewing machine from cutting thread when I sew delicate fabrics?
A: Use a fine needle and a thin thread for delicate fabrics. Reduce the tension settings to minimize stress on the thread.
Q: What is the best way to clean my sewing machine to prevent thread cutting?
A: Regularly remove lint and debris with a soft brush or compressed air. Apply sewing machine oil to the moving parts to lubricate and prevent friction.
