Bottom thread keep breaking , sew an inch then break !!

When the thread is fraying at the needle eye, it sometimes means the thread is being held back somewhere in the thread path. Remove the top thread. ALWAYS RAISE the presser foot and rethread. Verify the thread path is correct. Check the tension. If it is too tight, the tensioner is not allowing the thread to advance. (When you raise the presser foot, are you able to pull the top thread?) Try changing thread brands. Some threads and machines just do not get along. AVOID old or bargain bin threads. If you are stitching coarse, abrasive fabric, it can cause thread to fray and break.

check the age of the cotton
cotton is not a single thread but a series of fine threads bonded with a glue
old cotton glue breaks down and the thread separates easilty
next check that the needle is installed correctly with the grove ( thread groove away from the bobbin hook
check the needle and hook timing because if it is off a fraction , the hook will pierce the the thread causing it to break
next check that the eye is the correct size for the thread in use
a needle eye too small for the thread thickness will jam the thread ans not let slide through the eye properly

Remove all the threads.
Replace the needle.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify each thread is in the correct thread path.
ALWAYS THREAD each in the order specified or you will continue to have problems--for a lot of machines, the order is Upper Looper, Lower Looper, then needles.
Check the tension on that particular thread--too tight, it will break.

Breaking thread after about an inch usually indicates it is mis-threaded--a guide has been skipped or threaded out of order or the thread may be wrapped around something.

Sew What Up View thread Help Needle thread keeps breaking

Depends when/where the thread breaks and which thread breaks. Is it shredding or snapping? Does it break immediately or after sewing an inch or more? Is the needle the correct type for the fabric and the needle eye appropriate size for the thread weight?

All About Needles

Install a brand new needle.
Completely remove the top thread from the machine.
AVOID old or bargain bin threads--try a different thread.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the upper tension to the midway point and test the machine.

Be sure the bobbin is installed and turning the correct direction in the bobbin case.
Verify the bobbin case is threaded correctly.

Why is my thread breaking

Sewing Machine Problem 1 Thread Breakage

What Causes My Thread to Shred

I would change the needle because sometimes there is a burr inside the eye of the needle. Now when you rethread, make sure that your presser foot is up, and then pull on the thread to make sure that the thread is seated in all of the guides.

Needle breaks
1.the needle is damaged
2.the needle is not correctly inserted
3.wrong size needle for the fabric
4.the wrong foot is attached
5.the needle clamp screw is loose
6. Top tension is too tight
7. Machine could be out of time


The needle thread breaks

1. the needle thread is not threaded properly

2. The needle thread tension is to tight

3. The needle is bent or blunt

4. The needle is incorrectly inserted

5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew

6. the threads were not drawn to the rear after sewing

7. The thread is either to heavy or to fine for the needle

here are something you might check
upper thread breaks
1.top tension to tight
2.thread to thick or to fine for needle
3.needle not inserted correctly
4.thread caught on something-spool pin, tension area
5.needle damaged
6.needle thread is not threaded properly

Needle breaks
wrong size needle for fabric
wrong foot is attached
needle clamp screw is loose

also check for lint & pieces of broke needle under the needle plate
also the bobbin case area -take the bobbin & case out & check for pieces of broke needle

here is a tip about needle & thread
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

could the tension be adjusted to tightly
is thread feeding off cone/spool freely
also check to see if there are any burrs on the loopers or on the throat plate
here's a tip I learned from a needle & thread expert about needle & thread compatability

Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle

Happy Sewing

Hi, when your thread breaks or frays right before in goes through the eye of the needle:

1. Change your needle - after awhile, the eye can wear down and cause your thread to break or fray, eventhough it looks like the thread isn't even going through the needle. When you change your needle, make sure to install a needle that is compatible with the thread you are using (see below).
   
2. If your thread still frays or breaks, make sure you've threaded your machine correctly. Most machines have a hook or bar right above the needle that your thread need to pass thru before you put the thread thru the eye of your needle. Sometimes that spot above the needle is really hard to get to, and sometimes the thread slips out. Always a good idea to double check. If you are still having problems, the needle you are using is probably the wrong size.
   

There are lots of needles on the market, and lots of threads. You need to make sure your needle is compatible with the thread you use for each project.

The most common needles are size 80 and 90 universal needles, which are fine for most sewing projects. But if you are using a specialty thread, you need to use a needle that is designed to work with that particular thread. For example, top stitching needles have a larger eye than a universal needle, because top stitching thread is thicker than sewing thread. The same is true for metallic thread - needles made for metallic thread an eye designed to allow the thread to pass thru without fraying. Further, if you using fine thread, you need a small needle.

FYI - unfortunately, thread sizes do not correspond directly with needle sizes. Small needle numbers indicate a needle with a small eye. But the smaller the thread size, the larger the thread. For example, size 50 thread is very fine and would usually be used with a size 70 needle. Size 30 thread is fairly thick and would probably be used with a size 90 top stitch needle.

Hope this helps, and remember, you should always change your needle after about 10 hours of sewing, no matter what size needle you are using. If you have more questions, please post again. Thanks, Ginny

I had the same problem with the blue thread- it would sew and inch then pop- mine worked wihtout breaking after I re threaded in this order: green, blue, red then yellow
