I did a kerosine lamp test and a 100%vg wicking race comparing ramie to hemp fiber. Ramie showed as good or slightly better capillary action. These are not real lab conditions so results are not exact (hard to get two wicks exactly the same out of fibers). In the height above the liquid level that it reached in an hour, the ramie raised VG the highest of any wick I have tested, and slightly faster to raise VG 1 inch above the liquid surface than hemp.. As I said in the hemp thread I would like to get some ramie degummed fiber to test as what I have is ramie top. Have not had any luck finding the degummed ramie fiber. In earlier hemp testing the degummed hemp fiber wicked better than the hemp top.
I'm also looking for degummed ramie fiber, but it appears so far, it's only available by the truck load
