My first boats were wooden, and boat repair at the time used various impregnated fibers that had to stand up to moisture and abuse. Hemp, flax, sisal, jute, oakum, are all vegetable fibers. They were usually treated with something (tar, tallow, oil, wax, etc.), to increase the water proofing, but the general idea was that these fibers were the most impervious to moisture and rotting. That's not to say that they wouldn't harbor bacteria, just that certain types of fibres weren't susceptible to rot. I was always amazed by the continued use in the modern day of
waxed jute as a propeller shaft packing material. Delrin, Teflon, and other miracle synthetics are all available, yet jute coated in pig fat was still the packing of choice. Hundreds of hours of a spinning propeller shaft and salt water, and you had to renew the rope ever 5 or 10 years. Amazing.
Silk might have been chosen for woodwinds because it is a little slipperier than some of the vegetable fibers. It also can be made into a thinner thread for finesse work. And it doesn't swell very much when wet, which might be good.
I would recommend a
silk/bamboo mixture. It would just have to produce an exotic tone on a sax. And you could treat the thread with an exotic oil, like cinnamon, lemon grass, or thyme. Not only do these essential oils sound good, but they have antibacterial properties and even kill things like flu, pneumonia, and E.coli germs. Cork can't do that.
I see a new FlemTone product. And my Martin needs new cork (or a FlemTone
Exoticrook sealing system).
