Possible reasons for thread breaking

why does my thread keep breaking on sewing machine: Possible reasons for thread breaking

It is discouraging for your upper thread on your sewing machine to keep breaking free and tedious to rethread and fix it. There are a few reasons that could be causing the breakage while sewing your quilt or project. Knowing the reasons why the thread could be breaking free will help you to quickly identify the issue, solve the problem, and finish your work with ease. If you are asking yourself, “why does my thread keep breaking on sewing machine?” then here are some tips and tricks for you.

  1. If your upper thread is breaking free, the problem could be that it is not installed in the sewing machine correctly. Familiarize yourself with the upper thread strand and every part it connects to. By following the strand, you are checking to make sure the top thread is installed correctly at every point. This will help narrow down the cause of the thread breakage and make sure that you are inspecting the whole machine for any other problems.
  2. After making sure the upper thread is installed correctly, make sure the tension is not too tight. If there is an error here, the upper thread will not function properly or will snap easily. Take a look at the tension of the upper strand and make adjustments accordingly using the nobs on the sewing machine. In general, the higher the number on the dial represents a tighter tension, or pull, for the thread.
  3. Check to see that the spool of the thread itself is installed correctly in the sewing machine. Also, check that the correct spool cap is in place. It needs to coordinate in size with the spool of thread you are using. Be careful that the spool cap is not too small or too large or else the top thread could break free.
  4. After making sure the spool of thread is correct, you then should check that the needle is inserted correctly. The flat side of the needle should be away from you, and you can tighten the needle clamp with a screwdriver. Each sewing machine should have instructions to show how each part should be assembled and cared for.
  5. A broken or bent needle could also cause the top strand to break while you are sewing. Proper needle function requires a needle without bends, dents, chips, or breaks. We all tend to keep the needle in the machine until it is absolutely necessary to replace it, but be sure to check the needle itself every now and then for any issues that could be causing the upper thread to break.
  6. While you are checking the tension of the upper thread, you should also check the tension of the lower thread. The top and lower threads should have the same tension to achieve matching stitches. If necessary, the lower strand can be adjusted by hand depending on what machine you have. Older machines especially will need to have both upper and lower strands adjusted to the proper tension as the older machine do not have automatic adjustments.
  7. Be sure to check the bobbin thread and make sure the thread is evenly wound in the bobbin case. Slow and steady wins the race here, so make sure you are winding the thread at an even, slow pace.
  8. Your upper thread could also be breaking because the embroidery data has pitches that are set to zero. Check the data and be sure to erase all pitches of zero.
  9. Check to make sure the thread quality is not poor. The old thread will be lower in quality and will break free a lot easier than newer thread. Also, cheap or bargain thread is more likely to break than new and higher priced thread.
  10. Check that the embroidery data does not contain stitches with extremely small pitches. You should erase this could be the cause of the upper thread problem with the tiny stitches.
  11. There is a specific bobbin that should be used for each kind of sewing machine. You should correctly match the bobbin with the sewing machine for the best quality stitching and quilting. This is an easy way to make sure the upper thread will not break while moving through the machine.
  12. A pesky reason for the top thread problem is if the needle touches the needle plate. This could cause the needle to break or the thread to break. The jarring motion will snag the thread and break it, so make sure the needle is straight up and is hitting the correct part.
