Use a metallic needle, instead of your usual sewing needle, and you'll have less shredding. A metallic needle has a larger eye than an embroidery or quilting needle.But if it's last minute and you don't have time to go to the store to get a metallic needle, try using a slower speed and place the spool farther away from the machine. For example, put a thread stand next to your machine so you can run the thread to your machine, but place the cone of thread on the floor. Doing this helps the kinks work themselves out as the metallic is drawn off the cone as you sew. Try it, it works!! And remember to slow the speed down too.
Place a layer of dissolving stabilizer (I like the Light WSS by the yard the best) over the hooped fabric. Spray a light mist of food grade silicone spray over the WSS and place the hoop on your machine.This does two things....as the needle penetrates the top stabilizer, a tiny bit of silicone coats the needle, and by spraying the stabilizer, rather than placing a small bit of silicone on the thread, you avoid getting silicone on your tension discs.When you're finished, spritz some water on the WSS and brush it away.You'll find food grade (non-staining) silicone spray in quilt shops, or do a search online

I have been told by my embroidery group that using the thread stand and netting over the thread helps too. I am making a mini quilt that uses gold metallic thread and it is always breaking. since its a Christmas quilt, I've lost interest since the season is over. I'm going to get back at it soon, and I'm going to try the thread stand with the netting. Also, a good quality thread is best.
When you the netting I got my from the Flower shop it is free I place the netting half on the spool and just a little tucked under the cone.
Tuck the rest inside
and I turn my speed down on bar
I hope this help and I do use the sewers aid when I hear the machine getting labored I put it on the needle.
