Kevlar cord: 30 meters
Item sold in 30-meter rolls. The price shown is for 30 meters. Please note, the needle shown in some of our photos is not included with the spool of string.
30-meter spool of Kevlar twine:
To create or repair your own fire juggling equipment. This Kevlar string It allows you to sew your strands and create heat-resistant assemblies.
This allows certain constructions to be strengthened, but also allows wicks to be fixed together. while avoiding certain hotspots, such as on torches to swallow the fire .

Some interesting characteristics of Kevlar:
- Excellent resistance to shocks and fatigue.
- Good chemical behavior with respect to fuels.
- Significant moisture reabsorption (4%) requiring steaming before impregnation.
- Excellent heat resistance (decomposition from approximately 400°C).
What type of needle should be used with Kevlar?
For sewing with Kevlar twine, the same type of needles are generally used. only for leather. These are curved saddler's needles. NetJuggler does not sell Not this type of needle, but you can easily find them in haberdasheries.
We recommend using larger sizes to avoid injury. When sewing, using a small pair of tweezers can be very helpful for fingers.
Are you looking for string for a fire diabolo?
Thin Kevlar string is too thin to be used as diabolo string. For practicing fire diabolo, we recommend choosing the option Thick Kevlar twine , better suited for this use.
An unexpected use:
Some of our customers also use this Kevlar string to make Legs of lamb roasted with string. Thanks to its heat resistance, it won't burn. While it's cooking. We're still waiting for an invitation to come and taste it!
For what type of practice?
Fire safety equipment is intended for informed users and professionals. Fire remains an activity presenting significant risks.
Warning: This item can be dangerous. Always handle with care. Handle a burning object with care and have something on hand to extinguish it (a wet cloth is fine). (flammable, intended for this use only). This item is prohibited for persons under 18 years of age.

Hello, I just received your Kevlar string.
Which supposedly does not burn I just put the flame of my lighter
And your string broke an explanation
?
Kevlar is indeed an extremely tensile fiber: at the same diameter, it is stronger than steel. It is for this property that it is widely used in many technical and safety fields. 💪
On the other hand, its fire resistance has its limits :
Kevlar can withstand temperatures up to about 400°C (852°F ) continuously. But exposure to a concentrated flame—like the blue part of a lighter flame 🔥 that reaches well over 1000°C (2022°F)—causes it to degrade immediately. Therefore, even a simple lighter can quickly damage or melt the fiber.
In the field of fire juggling , Kevlar is used in very specific conditions:
🔥 The wicks are always soaked in dearomatized petroleum , a fuel that allows a relatively cool flame (mainly yellow) to be maintained, limiting direct thermal aggression on the Kevlar.
🔄 The apparatus (torches, bolas, staffs, etc.) are generally in constant motion during use, which helps avoid fixed points of localized overheating.
⚠️ On the other hand, if the still burning material is placed on a surface such as bitumen , it will reflect the heat, cause thermal accumulation under the Kevlar and quickly cause the temperature to exceed 400°C, leading to the disintegration of the fiber.
Additionally, the way Kevlar is mechanically stressed while burning also has a great influence on its lifespan:
🔧 When it is twisted, bent or rubbed while hot or burning, the internal fibers become fragile.
👷♂️ This is what we observe, for example, in some of our customers who build giant flaming puppets : at the pivots and joints, repeated movements and mechanical constraints accelerate the degradation of Kevlar.
✅ Conversely, in more classic uses (torches, bolas, staffs, etc.), where the Kevlar is in fluid movement and without too many mechanical constraints, our customers carry out several hundred ignitions of a few minutes before the Kevlar shows signs of wear.
For your project of hanging hams 🥩 over a fire or embers, you should instead choose specific ropes designed for cooking and holding under prolonged heat, which will be better suited to this culinary use.
Please do not hesitate to ask any further questions; I am available to provide any further information. 😊
Good evening, is this string compatible with the use of a fire stick or is it better to use thick string? Or another type of string or cable?
It's best to use the thicker string we offer on our website. We're working on a new Kevlar string that will be even better for use with Levisticks, which should be available by this summer.
Hello, is this string suitable for making a whip cracker?
THANKS!
This string is far too thin to make a whip cracker. Gora uses a 2mm diameter kevlar cord twisted around itself. We don't sell it by the meter, but we do sell ready-made crackers. Wick for Gora whip .
Is it possible to know the weight per meter of the thick string as well as the diameter of the thin string?
Good morning,
Can these strings be used for the fire levistick wire?
This string can actually be used for a fire levistick or for a non-fire levistick.
Good evening, for using a fire diabolo, is thin Kevlar string better or thick Kevlar string?
Thank you in advance for your response.
Please note this string will be too thin to be used as a diabolo string. If you want Kevlar string to practice with a fire diabolo, I recommend using our thick Kevlar string .
information on the diameter of the string.
Good evening,
Is this the right size to attach to sticks for making fire diabolo?
This Kevlar string is made for sewing Kevlar patches. It's also perfect for making flaming diabolos!
Hello, what is the diameter of the Kevlar strings? Thank you.
Thin twine is less than 1 mm thick. Thick twine is made up of several thin strings and is approximately 1.2 mm thick.
