## Description

Item shipped: 40 Yards of Nomex Thread on a METAL BOBBIN (as shown in picture). Excellent resistance to heat exposure (Nomex thread is not fire proof). Flame-resistant characteristics remain after laundering or dry cleaning. Please note: actual color may vary from picture due to computer setting. Details on Nomex can be found on the DuPont website. Google search "DuPont Nomex" without the quotes. PLEASE READ: All our FR materials, thread and products are re-tested by the SFI Foundation every 2 years. The SFI Foundation tests have specific methods and conditions in which the tests are performed. Holding a Bic lighter under a piece of Nomex thread is not the proper method to test fire resistant threads.PROFOX RACING is a current member in good standing with the SFI Foundation and has been for over 15 years.

Review: Economical & Right Amount for Small Projects - This was a great economical purchase! Thank you Profox! This is a bobin with 40 yards of DuPont Nomex thread and the right amount for my project. I paid $9 versus spending $40+ for large spool offered elsewhere on desertcart. I used this to hand sew a Coleman Stove Top Camp Oven insulating cover out of a Tillman Welding Blanket. I needed just enough to sew two 12 inch seams. It worked well. It didn't melt when using the oven on top of the stove. I had plenty of both left over to create a coffee pot cover. I should still have enough thread to make a smoker cover. If you have a small project this is great to use! I'm so glad this was available.
Review: Seems legit - Purchased this thread to sew patches onto my race suit. It can be hard to get nomex fibers in small quantities like this. While testing it, I was surprised by how easily it caught fire. After 10 minutes of research I learned that Nomex (meta aramid) thread is expected to burn, but is expected to self-extinguish. And this thread does self-extinguish very quickly once the thread is removed from the flame source.

### ⭐⭐⭐⭐⭐ Saved money with strong quality profox Nomex thread
*by R***Y on January 8, 2016*

Saved money on great quality product. I have been searching for strong nomex FR thread for months. I needed to repair Nomex racing suit and nomex work uniform/coverall but did NOT want to spend $55 on a big Nomex cone which was way too much thread for my few repairs. Found this profox nomex thread on Amazon and saved A BUNCH OF money! Thread came quickly and I repaired more than a few flame resistant/fire resistant garments including racing underwear, FR gloves from work, and even a friends racing jacket. Thread is strong and great quality. I have tried other brands that shed a lot of fiber dust in the machine, not this product it worked very well is strong great quality and held up to all of my sewing needs. Highly recommended product. Thank you Amazon for offering this profox nomex thread for a great price!
