Cpk,Not to hijack Elizabeth's thread - just thought some additional clarification might help everyone here.
There are many variables to evaluating the dielectric constant of materials. With cotton, as you point out, the amount of air and water in the material makes a difference.
With cotton, I recommend (anduse) a loose weave, almost a gauze, so the amount of air is maximized and the amount of water the material can hold is minimized. I also use pure, unbleached cotton, so additional impurities don't make matters worse, dielectrically. Overkill? Probably. But then again, that's what sounds best to my ears in my system.
YMMV. That's why there are so many different cable manufacturers, and highly rated cables, out there.
As for rubber, according to many different sites, the dielectric constant of rubber also varies: raw, 2.1-2.7; chlorinated, 3; hard, 2.8; isomerized, 2.4 - 3.7; sulpherized, 2.5-4.6; etc.
Take your pick and use what works for you. Generally speaking though, I don't see any figures quote for rubber that best decent cotton or Teflon materials.
So, in that way, raw loose cotton or Teflon's better than rubber.
