It has a very fast twist unlike threads you normally buy for leather machines. The purpose of this thread is probably to sew modern stretchy denim. I'm not that read up on thread, to be honest, but I get what you mean. That being said, comparing it to Gutermann thread I use without problem in the 545, the PolyArt thread isn't more elastic - but it's way more keen to split/unwind than the Gütermann thread is. You'd also think that, if that was the problem, it would differ a lot through the range of tension, right? Lower or higher overall tension (as in, both bottom and top) would make a big difference, and it doesn't... And funny enough, this is the most popular heavy thread offered by our biggest industrial sewing machine supplier here and they've carried this product for over 10 years. If this was a common issue, you'd think they would write something on their info page on it, but no... So friggin baffling, this. Quote

Btw, thread in all forms, beyond the domestic stuff, is really hard to source in Sweden. We really don't have a sewing industry here, so availability is very limited and what's available is very expensive. Quote
Members DrmCa Posted December 5, 2021 Members Report Posted December 5, 2021 If you've gone through putting a new needle in, checking the thread path for burrs and missed through holes, ensuring the correct tension top and bottom, then the thread is the only thing left to blame. We use the thread like yours for topstitching jeans, and all of the poly or nylon leather threads that I have has about 2x slower twist. This is all that jumps out on me.

Yeah, I'm ready to give up on it for the Pfaff 545. It's just annoying as I have so much if it, but I just can't spend more time fighting this. Quote
