Yahoo forum topic: Natural Fibers for Kites Compared with Synthetics
If we must avoid synthetic polymers for ecological reasons, then natural fibers really can do the job. We can maintain these fibers by traditional means and they will degrade into organic compost. Added cost is offset by enhanced ecological value. Value natural kites more. As Wubbo proposed, we can create the AWE we want, not just take the cheapest greediest route.
Check out how natural v. synthetics really compare. This link has good natural and synthetic fiber strength data (red dots on plot), where flax has stellar strength, and hemp and cotton also impress.

I’d sure like a source that is more recent and about more relevant applications and materials. It does give some info.
CBOS: Cyclic Bend Over Sheave
This is a good book for a pure insight into the fundamentals of what happens inside a rope, its fascinating and quite overwhelming the layers of complexity and interaction which occur inside a rope under stress and illustrates why it is so difficult to predict a ropes life on paper.

See what drives Edelrid to create some of the most sustainable products in the climbing industry. Get a behinds the scenes look at their R&D process and find out exactly how their ropes are made in Germany.
I think this looks like the perfect way to compare rope abrasion resistances; simple and cheap, repeatable, and easily variable with different weights and drum radii and coverings. I think it is better than the
Edelrid test I linked above, at least for our purposes:
Fishing line: Is Braid More Abrasion Resistant Than Mono? Find Out Here…
I guess the result could be explained by the high
Denier a monofilament fishing line would have . But perhaps its related forum comment cyclic bend over sheave (CBOS) could be worse than braided?
