Hi my names angela ive been a seamstess all my life. and it seems there could be a number of soulutions to your problem.first check your needle is in the correct way with the long ridge of the needle facing inwards.
second check you have the thread threaded correctly and it isnt twisted around twice anywere. and check that it pulls quite freely with ur foot lifted.
third. it could be flaw with ur spool case check it isnt damaged by running your finger along the edges if its catching u can file it down a little with a nail file.
fourth it could be your spool is not high enough in the case. so place ur case on a peice of paper and cut around a circle cut a smaller circle inside and insert it into ur spoolcase if your thtead is pulling to tight then you dont need that solution.
well i hope i was useful to you angela,,

The upper thread keeps breaking whenever I sew even though it is always properly threaded and the needle is fine

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

The top needle thread gets mangled,only way to fix is to pull all thread out and rethread the needle

Sounds like the thread is shredding and fraying. Make sure the needle is the correct size for the thread. Try a brand new needle. The other possibility is a possible burr or snag somewhere in the threadpath that is catching and fraying the thread. Another possibility is the fabric is coarse and rough and acts like sandpaper on the thread. AVOID old or bargain bin threads.

My Elna 730 pro. The thread is fraying and breaking.

Be sure to install a brand new needle that is recommended for the thread and fabric you are using.

Check to make sure the machine is threaded correctly. Remove the thread and rethread from the beginning.

Could be old/bargain bin variety thread. Use only fresh, good quality thread.

Another possibility is an incompatibility of needle, thread, fabric. Make sure the thread is not too small for the needle eye which will cause thread fraying. If the fabric is coarse or dense, it can also cause the thread to fray--a needle with a larger scarf (ie top stitch needle) will help protect the thread during the multiple times the needle pierces the fabric. In rare instances, the needle may be defective or there machine has a burr somewhere that is catching and shredding the thread.

It is important to install brand new needles frequently, ie every 8 hours of sewing. The needle is a very inexpensive item but could be very expensive in frustration, damaged fabric, and possible machine damage.

Juki Lu-562 breaking, fraying thread. The tread will fray and eventually break a lot. Is there anything else besides a different size needle or burrs on the foot plate for foot feed?

Be sure that you are using only fresh, good quality thread. Old or bargain bin thread will fray easily. Does the thread have little hairs (fibers) sticking out? If so, get rid of it. Try a different type of thread, ie polyester thread. (FWIW, Coats & Clark used by a stand-by, but it is a lesser-quality thread these days.) Be sure to use the same thread in the bobbin--polyester thread will tend to cut cotton. Try flipping the thread spool over so it feeds off in the opposite direction. Make sure the machine's bobbin area is clean of any lint or debris. The tension may be too tight. The thread may be mis-threaded or the thread is restricted somewhere, ie wrapped around a thread guide or the spool pin. Be sure the thread is running through the thread guide immediately above the needle. Remove the thread and rethread from the beginning. You might try a different type of needle, ie top-stitch needle. Top-stitch needles have a larger scarf that will protect the thread as it pierces the fabric multiple times before forming a stitch. A Top-stitch or Metafil needle has a larger eye to accommodate bigger thread. Are you sewing unusually coarse fabric? It is abrasive and could be causing the excessive fraying.

If the fraying continues, there may still be a burr somewhere.

Top thread keeps breaking

Upper thread breaking is usually a sign of incorrect threading or tension too tight, although there are other possible problems:

Industrial Garment Printers Sewing Machines

When threading the upper thread, be sure to ALWAYS RAISE the presser foot so the thread will seat properly in the tension disks. Avoid old thread or bargain bin thread. If the thread is fraying and breaking at or near the needle eye, then try a different type of needle with a larger thread groove that will protect the thread from fraying on rough fabric. Also, check that the thread is not hanging up on something, ie the slit on the side of the spool where the thread tail is stored.

Thread frays and breaks when sewing and embroidering.

Make sure that the machine is threaded correctly, that the needle is in properly, that the bobbin case and bobbin are both inserted correctly and that you are not using old thread.

Make sure that there is a new needle in the machine and loosen the top tension about a number

You need to carefully re-thread the machine.

Top thread breaking

Get a stuff called "Sewer's Aid". You can get it at Jo-ann in the notions department. It is a lubricant and I just recently used some to stitch rubber strips to nylon straps. The rubber is coated with an adhesive and without the Sewer's Aid, the thread would get gummed up on the adhesive, fray and break. I place the material under the foot, drop the needle and put just a drop where the needle goes into the fabric. It is very thick, like syrup and a little goes a long way. I have never used it on metallics but the way it helped me with the adhesive problem made me a believer.

Thread breaking on Simplicity Denim Star

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
