When I'm sewing fleece material the material wants to bunch up, how do I stop this?

Be sure to put in a brand new needle (Ballpoint or Microtex) and use a good quality polyester thread.

Lighten the presser foot pressure (if your machine has that capability). If that is not possible, you might find using a walking foot will keep the top fabric from "pushing" in front of the foot.

Sewing Fleece on Sewing Machine

No pre-set "setting" value for fleece, try a test sew to see how machine corrects for thicknesses. If sewing a lot of fleece remember to change needle when you go back to standard fabrics.The fiber dulls rotary cutter blade and dulls needles quickly.

For all machines that I have experience the reverse button or control is only use to lock the finishing end of your sewing & if reverse all the way would not work right.

try adjusting the top tension

make sure the needle can be used for sewing fleece

try rethreading the machine ,make sure each thread guide is used

if you try changing the top tension & the machine doesn't respond to any tension setting then maybe the tension dial needs to be replaced

make sure the bobbin is inserted correctly in the bobbin case

make sure the bobbin is wound correctly

clean under the needle plate & in bobbin area for lint or loose threads

1. make sure your machine is threaded right.2. set the tension between 3 and 4 and play with the tension as you need it to adjust it.3. make sure the bobbin is threaded right.make sure to visit the site below; it has solutions to multiple problems and instructions how to thread the needle or bobbin. Good luck.htt://Fix Looping/Knotting Thread Fix Knotting/Bunching Thread Looping Bunching & Knotting Thread

Hello

You are probably threading the machine incorrectly. Re-thread the machine very carefully as per your instruction manual.

If the problrm persists then You have a thread tension adjustment problem here

There is a tension adjustment knob this is usually located at a point in the thread's travel approximately half way down the sewing machine's head and the point where the thread is looped into a "tension spring"

It is at that point that you need to do your adjustment,tighten it slightly and make a pass of some trash cloth through the machine,if the thread's knotting up has improved adjust a little more test again until the proper tension is set

It should be fairly evident once you start this process if the tension needs to be slightly tighter or slightly looser you may even have to "tweak" this setting slightly once you have the actual project material into it's run because the type of material and the thickness of the needle's pass will have a lot to do with the necessary tension setting.The thread should "lock" at the back side of the material passing thru the machine to have the proper tension setting

Hope this helps you

This sounds like the tension is not set properly for what you are sewing.

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.

You may need to take off the housing that covers the whole dog mechanism. You will need a screwdriver to do this. Blow out the area around the tension gears and dogs, check for loose or disconnedted parts, and re-oil the gears. Fleece fuzz usually collects where you can't see it. This was the problem with my machine that had the same symptom.
