Gutermann Mara 100 - a Tex 30 polyester thread
 

Can anyone tell me if they have ever used this thread in quilting and on longarms?

The website Wawak says it is suitable for "outdoor wear". I had emailed them and they said it could be used for quilting and that the TEX is 40....but I have seen on internet that it is TEX 30. Would like to know before I purchase.
Thanks

I've never used it...but if its poly it should work as long as you use it in your bobbin also. Be sure to up your needle size with that heavy of a thread, imho.

Tex 30 is not the same as 30wt, so it may not be a thick thread.

Mara 70 is Tex 40; Mara 100 is Tex 30. So Mara 70 would be stronger. I found this thread (no pun intended!) that indicates Mara 70 is good for outdoor gear:

Also found this website that seems to list all the different Mara threads and their Tex numbers:

There was an interesting discussion on TEX a couple days ago:

I was incorrect, then, as I thought TEX referred to strength. Tex 40 would be a thicker thread (not necessarily stronger) than a Tex 30 thread. Found this explanation that helps too:

Oh fine. Just when I start thinking I might finally know everything I need to know about threads, you guys have to throw this "TEX" stuff into the pot.... and I'm back to being as dumb as a doorknob again.
