Kevlar™ thread is one of the strongest and most fire retardant commercially available threads. It is in the Aramid thread family and is about 2˝ times stronger than nylon or polyester, has almost no stretch, does not melt, and decomposes at 800°F. Our filament Kevlar is yellow and is called "Natural".
Metal Reinforced Kevlar -
This thread has a stainless steel core that is wrapped in Kevlar. This results in a stronger, stiffer, more abrasion resistant thread that still can be used for machine sewing. The thread has about the same diameter as our regular Size 92 Kevlar.
