This is exactly right. The Flash Point of Rayon is 681.8 degrees Fahrenheit (361 degrees Celsius). That is the lowest temperature at which Rayon will begin to vaporize into gas. Carbon Monoxide is not formed in this process. Carbon Monoxide is a product of combustion of the gas. The ignition temperature of Rayon is 842 degrees Fahrenheit (450 degrees Celsius). Most reasonable vapers are seldom if ever going to get anywhere near those temperatures even by accident and certainly not on a routine basis. And, no, Rayon is not synthesized (created by compounding chemicals). It is a product of processing natural fibers which consists of a purifying wash and rinse in the final steps that removes any chemicals used during the processing. Rayon is every bit as safe as Cotton and wicks (transfers liquid) much more efficiently.In the study, the wicks are burning I think. In a vaporizer, they float in liquid and they are heated. Gas emission should not be the same.
Well I'm nearly through the pack now, no off taste, but I did always fire them before I used them. Haven't used Japanese cotton in a while so shall order some this weekend, along with flavour concentrates and PG and VG and accessories, not due a mod till later in the month. Going for a squonker this timeI take it they are not labeled as organic cotton? For a small price difference I'd stick with ones labeled organic that specify how or if they have been whitened. Some organic cotton balls are whitened with hydrogen peroxide. This may or may not - according to your own taste buds - leave a bit of a taste for the first few hits on a new wick. The boiling is to remove that taste more than to sterilize them - although it will help with that as well. Some people aren't really concerned with any of that. You could try them as they are or boil them or go with organic and boil or not boil those. It's up to you.
I had some rayon shipped by Bondo in his package to me. It does seem supreme to cotton, I think I may order some on the weekend instead of Japanese cotton.I have a ton of Muji cotton, which is very good, but I always go back to rayon. I do find the flavor much cleaner than any cotton I've used.
Eco-wool seems to be OK, at least until I find something better.
You could also use a SS mesh for wicking.so, just run a wickless dripper... problem solved and VAPE ON!
Amanda, I do not know how your post got inserted into my reply, REALLY, I was talking to the clown with the rash from rayon... I apologize profusely...@Daniel What???? When on earth did I talk about Eco-wool LOL As far as I know I've never used it - I'm a rayon fan!!
I think you were quoting someone else!

I got a rash on my chest a couple days after I started using the Kayfun wicked with rayon. After spending the last week tracking possible causes, it appears that it is the rayon wick. I could taste the cooked rayon and it became more noticeable as the days went on.
I strongly suspect that cooking the rayon within a heating coil is not safe to vape. It is not possible to use rayon as a wick without cooking it to carbon when it has a heating element wrapped around it.I re-wicked every other day as the rayon was toast - completely broken down with the heat.
I went back to the mineral wick eco-wool yesterday. The rash has calmed down this AM.
There isn't anybody out there that is feeding us good reliable data on the materials we use for vaping.
We should be very conservative when evaluating new materials for ourselves.

Acute toxicity of the combustion products from various kinds of fibers.
Yamamoto K.
Abstract
Acute toxicity of the combustion products from various fibers was evaluated in animal experiments. The materials used were cotton, gauze, acetate, rayon, polyester (PE), polychlal (PC), polyvinylidene chloride (PVDC), silk, wool, polyacrylonitrile (PAN), and modacryle (MA).
Rats, mice, and rabbits were exposed to gases released from these materials, heated with an electric heater. In experiments with rabbits animals inhaled gases through a tracheal cannula under urethane narcosis. As indices for toxicity, the time at which animals were impaired severely, was used in rat experiments while the death time was used in experiments with rabbits and mice. The concentrations of O2 and CO in the exposure room were determined continuously, blood COHb and cyanide values were also estimated. Gases from fibers containing nitrogen impaired severely and killed the animals earlier than any other materials. Blood analyses revealed the presence of high values of cyanide in PAN, MA, and silk experiments. HCN was considered to be responsible for the high toxicity of gases from these materials. In the case of wool, despite of high toxicity of its combustion products, blood cyanide and COHb values were not very high. Gases from cotton, gauze, and rayon impaired severely and killed the animals relatively early in the exposure period. Toxicity of combustion products from these materials was attributable to CO on the basis of gas and blood analyses. Acute toxicity of PE and acetate gases, being less than that of cotton, gauze, rayon under the present experimental conditions, was explained mainly by CO. Neither severe impairment nor death occurred during exposure in PC and PVDC experiments.

Sorry to being up an old thread , but I also had problems with rayon. Gave me an extreme sore throat. Tried boiling it and had no problems after that.
Ohhhh you gonna be in trubba!!!After reviewing this necro thread, I have come to the conclusion that Amanda did it.

rash on your skin sounds like a reaction to latex in/on your clothing,,, or like my neighbor,, she suddenly could not tolerate her laundry soap of 20 years.I got a rash on my chest a couple days after I started using the Kayfun wicked with rayon. After spending the last week tracking possible causes, it appears that it is the rayon wick. I could taste the cooked rayon and it became more noticeable as the days went on.

Everybody assumes that I cooked the wick to charcoal - not so. I seldom dry burn or use high watts.
......I could taste the cooked rayon.......

Hi there, do you know of a store that carries them that I could just walk in and buy them I'm in Jacksonville Florida we have most of the big storesI use Japanese cotton, Shiseido. I don't burn it at all -- when I pull a gunked wick and rinse it in running water, the whole thing returns to pure white, so there's no burning at all. Considering I vape at 10w, that doesn't really surprise me.
I tried rayon briefly, but found I didn't care for the taste -- it does have a taste, and to some of us, quite unpleasant. The reason I like cotton, and that *specific* type of cotton, is the total lack of taste from the wick itself. With a new wick, I'll get a *vaguely* cottony taste for maybe 2-3 hits, and then it's gone. The rapid break-in is why I prefer Shiseido over KGD, or any other type of cotton.

I don't use them personally but there is a store called h-mart that sells them by me. it's an asian supermarket store.Hi there, do you know of a store that carries them that I could just walk in and buy them I'm in Jacksonville Florida we have most of the big stores
Cool thanks, says that just penny's has them too I'll probably go with nordstrumsActually, no; I had thought that Sephora carried them, but when I got there (after braving the xmas traffic and crowds at the mall in 2014!), I found that they didn't; they only had Ko Gen Doh and their own brand, but no Shiseido. I ordered them from Nordstrom, which offers free shipping on everything.
It wigs me out to realize I bought this pkg almost 2 yrs ago, and have used hardly any of it, even though I rewick quite frequently, about every 3-4 days.

^^^^DITTO^^^^ fantastic jooce flavor from the get-go, without the cotton taste.After using Rayon I can't use any thing else.
i wanted to try the ko gen do but im not sure what the specs are dont want to vape ground up bugs, the F5 cotton had none of that stuff in it at all, thats what ive been using
I use Asbestos
Last forever and glows in the dark too
My X wife got it for me
I really like KGD but it takes a minute to break in. But holds juice real well once saturated.i wanted to try the ko gen do but im not sure what the specs are dont want to vape ground up bugs, the F5 cotton had none of that stuff in it at all, thats what ive been using
For all of you telling good folks to use rayon, STOP IT! You are probably just paid by big rayon to inundate these vape forums with pro-rayon views. So why don’t you just admit it!! You guys are on Sally’s payroll and you know it. How many of you “vapers” hold stock options in rayon heavy companies? Ya that’s what I thought. Nah but rayon wicks nice and gives you some flavorful vapor. Cotton’s dead!! Long live Sally!
^^^^THIS^^^^---------Love it, laughing my ass off.
