Are you annoyed and wondering why my sewing machine’s thread keeps breaking? You’re not by yourself! Together, we will determine the cause of this issue and work on a solution. Let’s troubleshoot first. Sometimes simple things like using the wrong needle or thread can cause this issue. Check if the needle is the right size and type for your fabric.
Also, ensure the thread is suitable for your machine. If they’re off, it can lead to thread breaks. Remember, patience is key. Sometimes it takes a bit of trial and error to find the exact issue.
But with persistence, you’ll likely sort it out! You’ll soon enjoy seamless sewing again because in this article we will discuss the main thread-breaking causes and will discuss their solutions as well.
1- Why Does My Top/upper Thread Keep Breaking (Janome)?
Understanding the frustration behind constant top thread breaks is crucial, especially with Janome machines. Given below are some main causes of top thread breakage in sewing machines especially Janome.
Thread Quality & Needle Selection:
- Using suitable, good-quality thread is vital. Avoid mismatched threads, especially on Janome machines, like rayon for denim seams.
- Ensure the needle matches your fabric and thread. Mismatched needles can significantly affect delicate threads and intricate stitches.
Threading Precision and Thread Delivery Setup:
- Check all thread guides meticulously. A single missed guide can disrupt sewing on your Janome machine rethreading may be necessary.
- Ensure smooth thread delivery to tension discs. Incorrect spool caps or tangled threads can cause breakage issues specifically on Janome machines.
Inspecting Needle Plate & Bobbin Case:
- Regular cleaning of the machine prevents lint buildup, a common cause of thread breakage.
- Damage to these parts on Janome machines can lead to thread shredding. Seeking help from a Janome dealer is advisable if uncertain.
2- What Are the Reasons Of Bobbin Thread Breaking And Bunching?
Over time, as you sew tiny dust and thread bits gather under the needle plate. You should regularly dust under your sewing machine’s throat plate to remove dust, dirt, lint, and debris.
Even if you’ve rethreaded, adjusted tension, and checked the needle, persistent bird nesting means checking your bobbin under the throat plate. If it’s inserted incorrectly or dislodged while sewing, it can cause bunching.
Remove everything, check for bobbin damage and lint, and insert it correctly, ensuring proper threading. This helps to prevent these issues. If your bobbin thread keeps breaking and bunching, here’s why. If it’s inserted backward or gets dislodged while you sew, it won’t move correctly, causing bunching.
So, clear out everything from the bobbin area, check the bobbin for damage, and clean out any lint. This usually fixes the problem.
3- Where Bobbin Tension Goes Wrong- Why Does Bobbin Thread Keeps Breaking?
When bobbin tension isn’t right, the thread struggles, leading to breaks. Incorrect tension, whether too tight or unbalanced, disrupts the sewing process. Adjusting it carefully can resolve issues, allowing smoother stitching and preventing frustrating thread breaks in your sewing projects.
If your bobbin thread keeps breaking despite rethreading and adjusting upper thread tension, it’s time to address bobbin tension. This adjustment, although infrequently recommended by machine manufacturers, becomes necessary to prevent thread breakage.
Bobbin thread issues often arise due to unbalanced or overly tight tension, causing breakage. For an easy sewing experience and high-quality stitches in your projects, it’s essential to check the bobbin tension.
4- Why Does Thread Break While Sewing Thick Fabric?
Why does my thread break while sewing thick fabric? The thread might be too thin or weak for the job. Check the needle size and strength to avoid fraying or splitting stitches. Matching the thread to your
curtain fabric ensures a neater finish and durability, crucial to prevent rusting over time. A thread that’s too fragile easily snaps with heavy fabrics.
Choose a thicker thread, at least 3/8″ in diameter, to withstand the pressure. Thread breaks often result from incorrect tension, poor seam placement, or faulty equipment. To prevent these issues, take extra care when sewing heavyweight fabrics.
Using the right thread thickness, matching it to your fabric, and paying attention to sewing techniques can minimize thread breaks when working with thicker materials.
5- Needle Thread Breakage Causes And Their Solutions
Unequal tension between upper and lower threads, incorrect needle installation, or using old, poor-quality thread can cause breakage. Needle thread breaks during sewing due to several reasons.
Causes of needle thread breakage:
- Unequal tension between upper and lower threads leads to breaks.
- Incorrect needle installation or old, poor-quality thread causes issues.
- Loose yarn in the shuttle or high upper thread tension can result in breakage.
- Improper bobbin threading or tension leads to frequent breaks.
- Trapped thread in the bobbin case can cause repetitive breakage.
- A misaligned or damaged needle affects thread integrity during sewing.
Solutions of needle thread breakage:
- Use a foam pad under the yarn package to prevent swinging.
- Thread more through the guide and reduce tension on the disk.
- Decrease the check spring’s pressure to improve sewing.
- Opt for better-quality needles for smoother stitching.
- Maintain adequate oil supply for machine and needle lubrication.
- Check the distance between the needles and the hook.
- Replace poor-quality yarn to avoid sewing issues.
Frequently Asked Questions
How can you prevent your sewing machine’s thread from breaking?
If your thread keeps breaking, it might be too thin, old, or damaged, or your tension setting could be too high. When working with thicker material, you might need a thicker needle, choose thread that suits the fabric, and lower your tension setting. This can help prevent those frustrating thread breaks during sewing sessions.
Why do sewing threads break during sewing?
Often, thread breakage happens due to an incorrect needle. Before you start sewing, ensure your needle matches the thread size for your project. Remember, the smaller the number on the needle package, whether in American or European sizes, the smaller the needle. This simple check can help prevent frustrating thread breaks while sewing.
How can I determine if my bobbin tension is right?
If it’s too tight, the fabric might gather, and the bobbin thread could show on the top side. If it’s too loose, you might spot loops on the top side and notice the spool thread on the underside. Checking these indicators helps you adjust the tension for smoother sewing.
Conclusion:
It might be annoying to deal with your sewing machine’s constant thread breakage. If you’ve questioned, “Why does my thread keep breaking on my sewing machine? For the upper thread, it’s often due to thread quality, needle selection, or issues with threading precision and delivery setup.
On the other hand, bobbin thread breaks usually stem from incorrect insertion or accumulated debris. Bobbin’s tension problems can further aggravate these issues. However, finding the precise cause and solution, be it for thick fabric sewing or needle thread breakage, demands attention to detail.
With the right tools, like better-quality needles and adequate lubrication, you can minimize these disruptions. You may improve the smoothness and enjoyment of your sewing experience by comprehending these problems, their origins, and how to solve them.
