Broken and bunched thread on back of fabric

Looks great from the top, but the under side the top thread is bunching and broken. Cleaned and oiled, but still breaking and bunching...Makes a different noise and thread breaks. I recently have been learning free motion quilting. Thanks!

Try changing the needle
also try adjusting the top thread tension and see if that helps
make sure the top thread has not come off the thread take up lever
also the machine may need to be checked for a timing problem.

Could that pack of needles have been bad? The new needle today was from a different pack. ?? Thanks so much!!

  • it might have been just that one needle was bad, you can try the other needle that came in the same pack and see if they are good, you will be able to tell real easy if they will sew good or not. happy sewing

    Thanks so much! I will try the other needles and toss them if they make the machine do the same thing. Thanks again!!

SOURCE: Thread bunching and knotting under fabric

The thread does pass over the top of the bobbin case to form a stitch, perfectly normal, whether front or top loading bobbin.

Ensure that all is clean and free of lint jams....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.
The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your
projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with
a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to
disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

After all this, it's OK to tighten your tension up on top a little when free motioning and getting eyelashes/spider webs on bottom. around 6 should do it though.

Try a different bobbin. Look for one that is a little narrower. I had the same problem and changing to a narrower bobbin fixed it.

Make sure that you have the top thread in all the correct positions. I missed two and had the same problem. When I rethreaded it my problem was solved.

When I sew I have thread bunching up underneath the fabric, I've changed needle size, thread, bobbins and cleaned out around the bobbin holder. I'm frustrated and out of ideas.


Susan--
Easy peasy, once you know the problem and how to fix it. It's called "bird nesting" or "thread nesting" or what I refer to as thread "barfs."

Install a brand new needle.
Remove all the thread from the machine.
**ALWAYS RAISE** the presser foot and rethread the top thread.
Verify the top thread path is correct.
Install and thread the bobbin case, make sure it is correct.
Set the top tension to the midway point.

Now retest your machine. Birds nests gone? You may need to tweak the top tension because the factory standard changes due to age and use.

FWIW, problems appearing under the fabric are an issue of the top thread. Thread problems appearing on top of the fabric is a bobbin issue.

Bobbin issues the bobbin thread is bunching up


Check whether it is bobbin thread or the top thread accumulating under the fabric. Generally, if thread problems exist "under" the fabric, it is a top thread issue. If the problems exist "above" the fabric, it is a bobbin issue.

Sounds like a thread nesting (bird nesting) problem where the top thread is globbing under the fabric. Usually, this is caused by misthreading (confirm the thread path), the thread not seated in the tension disk (ALWAYS RAISE the presser foot when threading!), or very loose top thread tension.

Remove the thread. Raise the presser foot and rethread from the beginning. Check that the thread path is correct. Set the upper tension at the midway point between high & low numbers (this is the beginning point for tension and will most likely need to be tweaked for your particular machine).

That is thread nesting or bird nesting. Could be the result of several things, but main reasons are upper tension too loose and the thread not being completely seated in the tension disk.

My bobbin thread continues to bunch up on the back of the fabric.. How can I fix this?


Is it really the bobbin thread that is globbing? Check closely. Usually it is the upper thread accumulating under the fabric.

If it is in fact the bobbin thread, then the bobbin case is not threaded correctly, the bobbin case tension needs adjustment, or it is broken and needs replacement. There are web sites and YouTube videos that show how to adjust the bobbin case tension.

QUICK FIXES: Remove all the thread from the machine. Clean the area around the feed dogs and bobbin area. Oil as instructed in the owner's manual using ONLY fresh, good quality sewing machine oil (only 1-2 drops each spot). Install a brand new needle insuring it is installed correctly. Avoid using fuzzy, old, or bargain bin thread. Rethread: Be sure you raise the presser foot BEFORE threading the upper thread so it will seat properly in the tension disk--and check to make sure you are threading the machine correctly. Check that the upper tension is set properly (the factory standard is usually the halfway point between the high & low number on the selection). Test on a scrap of the fabric you wish to sew. Adjust the upper tension--either tighten to pull the upper thread toward the top of the fabric, or loosen to pull more upper thread down.

Here are some web sites that may help.

When i run a straight stitch, the top of the fabric looks well sewn; the thread on the bottom of the fabric, however, bunches up-it looks nothing like the top stitch.


Is it really the bobbin thread that is bunching under the fabric, or is it really the top thread that is creating loops and "bird nests" under the fabric???

Rethread your upper thread. BEFORE you thread the upper thread, be sure to RAISE the presser foot. This releases the upper thread tension disks so the thread is firmly seated in the tension disk.

If it continues to be a problem, then the upper tension needs to be tightened. Adjust slightly, then test. Repeat until the upper and lower threads meet in the middle of the fabric.

Jamming brand new machine


the tension on the bobbin case needs to be adjusted to needle size and type of fabric the medium fabrics usually use a size 11, light fabrics need a size 9 and heavy like ( corduroy denim or upholstery fabric needs a 14 or 16 Heavy fabrics need a little less tension on the top side so it will feed properly just play with it until it looks good on a scrap of the same fabric
