The KEVLAR® thread we sell has a breaking strain of 12.5Kg. It is ideal for stitching KEVLAR® wick onto fire props. If you keep the stitches deep within the wick and pulled tight it will last for years.
However if you let the fire wicks smoulder by allowing all the fuel to be used up then the KEVLAR® wick will burn away slowly and fall apart and eventually do the same to the thread. Sunlight also degrades and darkens the color of KEVLAR® wick slowly over time. So it is good to have wick covers when using Fire Props during daylight, it also stops you getting your daytime clothes dirty from the residues on the wicks.
A lot of people fasten wick onto their props with screws and to stop themselves from getting branded by a hot screw head they stitch a flap of KEVLAR® tape over the screw heads.
Because of how expensive KEVLAR® is compared to other threads we sell on small spools (which is the most popular size). If you want only a small amount we also sell per meter or per ft (units depend on the language settings) and if you are a big time manufacturer we have the large spools also available.
Cutting KEVLAR®KEVLAR® has a very high cut resistance. Which means it will blunt even the most expensive scissors very fast. At HoP we use box cutters or craft knives which have replaceable blades. Do not ever use your mum's favorite dress fabric scissors or you will be in big trouble!
About KEVLAR®KEVLAR® is one of the most important manmade organic fibers ever developed. Because of its unique combination of properties, KEVLAR® is used today in a wide variety of industrial applications. KEVLAR® para-aramid fiber possesses a remarkable combination of properties that has led to its adoption in a variety of end-uses since its commercial introduction in the early 1970's.
Fibers of KEVLAR ® consist of long molecular chains produced from poly-paraphenylene terephthalamide. The chains are highly oriented with strong interchain bonding which result in a unique combination of properties
