Top thread breaks when using metallic thread

Metallic thread is often easier to break when sewing. Make sure the thread is not brittle and old; It may also require "Metallic Embroidery" needles that have a slightly larger needle groove and eye spaces. Also, make sure your thread does not have additional tension on it when being fed from a vertical spool. allow the thread to flow horizontally off of the thread spool into the machine.Or place the spool bottom down on the table next to the machine and let the machine pull it up and over through the machine which needs to be very properly threaded.

Metallic Thread

If the problem continues, I would try different brands of needles and thread.

I'm not exactly familiar with your machine but... a few things you should know. 1. You need a metallic thread Needle. or at least one with a larger hole. 2. Check your bobbin carrier, if anything catches or jams between between the spring and the case it can loosen the bobbin tension and make the top show too much bobbin color. 3. If your bobbin spring becomes grooved from the wear of the thread... same thing. 4. If your spring and everything is ok and clean... tighten the tiny screws to tighten the bobbin tension some.

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

check to see if there are any burrs in that area

check the tension
if the thread will not easily pull thru the needle eye you need one size larger needle
also keep under the needle plate clean of lint
& also the bobbin area

Three things to check:

1.You need to use a needle specifically made for metallic thread. I believe the eye of the needle is square and the thread will pass through it easier, and will not be shredded which can be a cause of breaking.

2. Be sure to check your tension to make sure it is not too tight on the top. Test your stitches, checking both top and bottom tension.

3. The thread should come off the spool straight, not twisting. The thread cone should be standing up straight and the spool should twirl to release the thread. If the spool is not moving and the thread unwinds from the stationary spool, then the thread is twisting and that can cause the breakage as well.

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....I tried cleaning it just like you did. Eventually, I changed the needle and it took care of the problem :)
Hope that helps!

Try using a bigger needle
