I am sewing with Matte Jersey Knit and continue to get loops underneath my work. I have consulted the manual and adjusted thread tension, changed the needle and thread. Adjusted the pressure dial and I still get loops! What am I doing wrong. Is it the material that I using? I thought this machine could handle anything.
It's most likely not the machine. It's the other things, ie needle, thread, etc. combination. For sewing knit, be sure to use a ball point needle. The needle eye size is important to so the thread is neither too small nor too large for the thread weight.
FWIW, it sounds like bird nesting. --the thread is not seated completely in the tension disk. Remove the top thread from the machine and ALWAYS RAISE the presser foot when rethreading!
Also, check that the tension is appropriate for the project. The two threads should meet in the middle of the fabric. If there is top thread showing on the underside of the fabric, the top tension is too loose. Tighten it until it until the top thread pulls the bobbin thread up into the fabric.

SOURCE: looping underneath
I watched a 'You Tube' demo that showed ........if you loosen or tighten the very small screw at the base of the bobbin this gives you the correct tension & stops the looping under the fabric........I didn't even know this screw existed ! It is trial & era at first re the correct tension but you do get there.... the art is to do it in small mini stages.....like you hardly move it ! Thanks to 'You Tube' I can now get on and finish my drapes !

Put the tension settings back to the mfg's suggested setting.
Re-thread the machine with the presser foot up and there will be no more loops.

If the machine is now threaded, lift the presser foot.
Now, pull about 10" of thread through the needle.
The next time you thread the machine, lift the presser foot first.
When the presser foot is up, the tension control opens and allows the thread to "seat" into the control, then when the foot is down the control closes to the indicated setting.
When threading the machine with the foot is down, thread does not enter the tension control and when you start to sew, there is no tension on the thread.
No tension = loosey, goosey, loopy stitches underneath.
Because the lack of tension on the top thread, the bobbin thread cannot lock a proper stitch.

This is a top tension issue, you need to check two things,
-make sure you thread the machine with the pressure foot up ( this allows the tension discs to open up so you can pull the fabric away from the machine with the foot up and allows the thread to get to bottom of the tension discs)
-make sure your tension settings are set to the medium setting. (Usually 4 or 5)
If this still does not help, then turn the top tension knob up (from 5 to 6,7,8,9....)
-If that still doesn't do it, your probably need the tensions reset, and your local family sewing store will be able to assist you further.

It is most likely because you have it on a type of stitch but did not switch the didstance that you want the zig zag to be. Just change you stitch or your distance.
