Hey, back to the rayon discussion: I know that rayon wicks more efficiently than cotton, due in part to the more linear alignment of the fibers. And I can see how this would be an obvious advantage if you use heavy VG and/or chain vape. Even though I've read that it's a bit fussier to set up, I thought about trying it, because those that use it rave about it, and the flavor it gives. But doesn't it have a lower threshold for burning than cotton? I tried looking it up, and was directed to sites talking about ironing clothes. And one had a scale of 1-7, 7 being the hottest to use, and cotton was a 7. Rayon was a 3- and it recommends ironing rayon clothing inside out to prevent damaging the finish of the exterior. Another discusses how rayon is much more susceptible to loss of stability when wet. I couldn't find anything about advances in rayon that was used in wicking material, or anything temp related discussing rayon wicks. But wouldn't the lower temp resistance make it last a shorter time? I was wondering if anybody that has both ever tried it on a coil dry, just to see which singed or burned at a lower temp.
Doesn't really matter, rayon isn't going to burn under normal vaping. Try it, see if it works for you. There's a thread dedicated to all things related to wicking with rayon here --> https://www.e-cigarette-forum.com/f...er-flow-flavor-saturation-and-nic-hit.561226/
