What's the differences between Settanyl Brazilian Waxed Polyester and C-Lon Bead Cord?
Nylon versus Polyester
Nylon is made out of continuous filament fibers. It imitates filament silk. Polyester is made of shorter fibers, spun together the same way as cotton and linen.
Expect more stretching with polyester. Nylon after an initial stretch has minimal stretching.
2 Ply versus 3 Ply
C-Lon is a 3-ply cord. Settanyl is a 2-ply cord. 3 ply construction makes a rounder cord. 2-ply construction makes a cord that can be more easily flattened.
Bond versus Wax Coating
Bond is an applied coat to the cord after it has been extruded, spun and plied. It is similar to a resin coat that's applied, then dried in an oven. Tack is also often applied to cord when it is wound on spools. It kelps the spools from unraveling. Bond sometimes whitens over time when exposed to changes of temperature or heavy handling. Rubbing alcohol applied to the cord surface restores the transparency of the bond.
Wax is applied after the cord has been plied. Wax is not a permanent finish. Over time the wax coating gets thinner, leaving the cord more susceptible to wear and tear.
The Settanyl Brazilian Waxed Polyester is about 1mm in diameter, just a tad thicker than C-Lon Tex 400 Bead Cord, the heavier cord of C-Lon.
Wash & Wear
Both types of cord can be washed. Both will fade with long exposure to sunlight.
Bonded nylon is a bit harder to knot. Waxed polyester is easier to knot as the first half of the knot holds itself better as the wax creates a form of adhesion. Undoing knots is easier with bonded nylon and much harder with waxed polyester without damaging the cord.
In the end it is all about personal preferences. Many types of knotting lend themselves to waxed fibers. Some artists, experts and beginners alike, will love the availability of this cord.
Personally I would get a few spools to test if I could. Unfortunately, I have a major skin sensitivity to the wax coating on this thread, so I will leave this thread to other to play around and experiment with!
