KEVLAR(R) is a para-aramid, a member of the aramid family of
manufactured fibers. Aramid fibers have no melting point, low flammability, and
good fabric integrity at elevated temperatures. Additionally, para-aramid fibers
have excellent strength-to-weight properties.
Fire performance equipment manufacturers and wick suppliers
deal mainly in materials that contain a blend of aramids (both para- and meta-aramids)
and fiberglass. Aramids lend greatly to the physical structural integrity of a
fabric, while the small amount of fiberglass adds somewhat to the thermal
integrity of the fabric. Blends are also a cost-effective solution; while some
retailers may deal in pure KEVLAR(R) fabrics, it is rare, as pure KEVLAR(R) is
very expensive and an inferior thermal solution.
The firedancing industry generally lumps all aramid blend
wicking into one category, and calls it "KEVLAR(R)." At Flamma Aeterna,
you can find three types of wick material: two different aramid/fiberglass
blends (called K1 and K2), and one of pure KEVLAR(R) (called KX):
- K1 material is the blend most widely used as wicking by the fire-dancing community.
Tapes are made of KEVLAR(R), NOMEX(R), and fiberglass. Ropes
are a tubular blended braid with a fiberglass or K1 (i.e., blended) core. The
braided ropes are not as flexible as the K2 ropes, but are generally more
- K2 material is woven aramid/fiberglass, and is the default for most of our equipment
options. It is slightly better-priced, and, though rated as 1/8 in., it is
slightly thicker than K1 tapes. Otherwise, the K1 and K2 tapes compare very
similarly, performance-wise. Ropes
are less durable than in K1series, but are, initially, much more sponge-like and
The weave is
more basic than the K1 weave, lending to increased fraying when cutting; glue or
tape ends when cutting or storing. In finished products, this is not generally
noticeable because ends are concealed or glued to limit fraying.
- KX material is made of pure KEVLAR(R), and can be found in our threads and
