It actually gets a bit more complicated than even that...saince the
diffrenet materials have different densities, denier, which is based
on mass per 9000 meter of fiber, is close but not exactly the same.
For example, for a series of 50 denier gel spun polethylene (density
approximately 0.95 g/mL) would be the thickest, followed by nylon 6,6
(density = 1.14 g/mL), then silk (density - 12.5 -1.34 g/mL), then
polyester PET type, polyethylene terephthalate, density - 1.37 g/mL)
with the thinnest being Kevlar (density = 1.44 - 1.49 g/mL). this is
ignoring any diffrences in how the strands of the fibers arre twisted
together. If comparing a single fiber, a gel spun polyethylene fiber
of the same denier as a Kevlar fiber would be about 1.55 times as
thick. another words, denier sizing is an improvement, but really
should only be used to compare threads made of the same base material.
that or you can use the densities listed above to figure it
out...more apples and oranges...my personal prefference would be for a
and average thread diameter rating, but I doubt that will ever happen.
Anyway, I usdually don't need anything beneath about 140 denier...
