SAUNDERS THREAD SPECIFICATIONS
KEVLAR® IS THE REGISTERED TRADEMARK FOR DuPont's family of high-temperature-resistant aramid fibers having a unique combination of toughness, extra-high strength and exceptional thermal stability. SAUNDERS THREAD manufactures both continuous multifilament and spun KEVLAR® for a variety of sewing operations. Continuous multifilament KEVLAR® is available in both soft and bonded, but only in natural yellow color. Spun KEVLARŪ is available in a range of package dyed colors. There will be strength loss when dying the Spun KEVLAR®. This should be taken into consideration when selecting the correct Tex and Yarn Size. The spun fiber is considered un-dyeable and some variation can be seen from one lot to the next.
