Rayon wick, better flow, flavor, saturation and Nic Hit!

[VenusianSky]

The only safety item that I found worth repeating and that is burn a piece and make sure it burns fast, smells like burning paper and leave nothing but a fine ash. If any synthetic i.e. plastic, synthetic fibers have been mixed in you will notice it tends to shrink into a ball and leave a black balled up blob.

I did the burn test as well. Wasn't quite ready for it, cause that sucker went up quick. I was standing next to my kitchen sink for a reason, but I didn't think I was going to have to throw it in so quickly. I guess I wasn't thinking that this stuff is sort of like a puff of micro fiber paper.

Hi guys... if anybody would be so kind as to send a sample of CC to Italy, I could surely use the help. I've been searching all over Europe, but even Amazon UK appears to be shipping them from the States... and it's a big package. Ready to pay for material and shipping, through PayPal. PM if moved by my situation.

I know exactly what you are talking about. It reminded me of the days when I used to reload shotgun shells and use a black powder rifle. I would burn old shotgun powder to get rid of it and it burned pretty good. One day after giving up on guns I decided to get rid of my black powder by burning it... bad mistake it doesn't burn it flashes like the old time flash bars that photographers used.

The article I read on the burn test for rayon suggested having an empty metal mop bucket very close to pitch it in when it burned a little faster than your worst nightmare.

Yeah I know what you mean, it went faster then I thought it would.

Slick,

Just wait until the first report comes in when someone hits the fire button before priming.


PS - and yes sometimes I get lazy and don't remove the Bat before re-wicking. But so far I have been lucky.

 

[JeremyR]

Just curious if anyone using this stuff cares or thinks about if rayon is safe or not to use as wicking material??? Don't really hear anyone talk about this

Lol

It's been talked about pretty exhaustively.

If you put upr settings in 30 posts per page instead of 10. Then do an advanced thread search for my user name. That will make the posts regarding safety and technical data easier to find.

Rayon has gained GRAS status, (generally regarded as safe) no one has brought anything forward showing otherwise.

Rayon a is created when it reaches this formula- (cellulose OH + na2So4 ) it's then rinsed of salts to become (cell OH) pure regenerated cellulose. From a tree, ect.

I don't recall anyone ever "proving" that cotton was "safe", or silica, or yarn, or bamboo, or mesh, or hemp, or ceramic .. or any of the other wick mediums. Is there a post somewhere that offered proof that "those" wicking mediums are safe? If so then I must have missed those posts .. would love to see the "proof" that those are "safe".

I'm in Italy, and I do have some rayon to share.. Only it's not cellucotton, it's no-brand rayon fiber.

PM me, in case you're interested

Amen "stashbldr"

Case in point XC-116 or whatever they call it now. The vaping vendor of this stuff gives you all the hazardous chemicals contained in the virgin form and warning from the manufacture. They also tell you what the manufacture says you must do before using it as a wick material and insists that they do what the Mfg instructs be done and then goes a little bit over the recommendations.

Now keep in mind that all these ceramic / glass fiber materials i.e. ekowool, silica, glass and whatever you want to call it is designed as high temperature insulation for thermocouples (temperature probes) used in furnaces and other high temp situations as is G.E.'s XC-116. when used for it's intended use health concerns are probably the furthest thing from their minds.

Cotton manufactures' have had more than their share of heath problems in the processing of cotton over the years just ask anyone that lived in one of the southern communities that were for all practical purposes a "Cotton Mill" towns.

Considering that I smoked anything I could get my hands on for 30 years, and have seen what people would do for a cigarette, including trolling sidewalks for smokeable butts, the paranoia over safety just makes me snicker a little bit. I think the only completely safe thing to do would be to not smoke or vape, as the only safe thing going into your lungs is AIR. But between smoking and vaping, I'm happily taking my chances with vaping, and I'm awed by the tech advances that make it better and better, rayon being one of them. It works great, it's somewhat organic, not plastic, takes a lot of effort to burn and doesn't shoot shards into my lungs, so I'm happy. Now to get all these tank manufacturers to stop using polycarbonate on everything...

I would venture to say - This is the most researched wicking material of all time.

Research all the way down to the molecular level..

(You don't want to know what I stumbled accross about cotton. You don't.... (I'll just say possibly DM's are what you see under magnification) not to mention something else in china)

Ok, I've spent the weekend testing rayon fibers and ramie..

The rayon I've got from the UK came in two types, rayon top and crimped fiber, quite different to each other.

The top variety looks very similar to ramie, or hemp sliver (and possibly cellucotton), while the crimped one is a tangled mess of fibers, like what you may rip out of a cushion

To sum it up both of them work quite well, even though I have to agree with Jeremy: the med bottle rayon I have is in another league.. And by far.

These fibers are rougher, and less densely packed, than medical grade rayon - they work, nonetheless, but to a lesser degree than I expected..

Paradoxically - I was expecting the other way around, for some reason - the 'crimped' fiber seems to wick slightly better than the rayon top; when wet it becomes almost transparent, while the top maintains a more withe-ish color, provided that matters.

It must be noticed that I've boiled the rayon for some time before using it, like I'd have with hemp.

All in all yes I'm satisfied with this rayon but I will definitely pursue the med-grade rayon option

Sorry about the lengthy post.

 

[stashbldr]

the paranoia over safety just makes me snicker a little bit.

Yep, me too ... I always get a laugh out of people asking "is this material safe, is this liquid safe" .... heck we have NO CLUE if vaping itself is even safe! We're pretty sure it's safer than the cigarettes we smoked .. but no one has PROVEN anything about vaping is safe! Meanwhile, I will continue to vape myself silly using only RAYON!

Proof was never mentioned. "generally regarded as safe" is not even close to saying something has been proven

...maybe I misinterpreted what you were inferring

 

[stashbldr]

..maybe I misinterpreted what you were inferring

Yeah ... I am "inferring" that unless people have "proof" that those other wicking materials are "safe" they need to quit asking us for proof that rayon is safe.

I thought I was the only one that did that but I never would have admitted it until I read your post.

Okay, thanks to a bad rinse (drain got it) I didn't get the pics I wanted of an RDA wick that was thinning on me.

Noted issue was the slow dissolve of the Sally's from high acidic juice (best guess) over a week long period. (was able to use up some juice I like without it going to zero taste on me thanks to Rayon fwiw) Moderate use ~15 ml. This was interspersed with clearing the wick with pure VG and non-flavor most VG for probably another 15 ml.

Wick was burned many times (like extreme dry hits from triggers firing while standing, etc) ... The burnt portion I expected to see when I first pulled it out a little wasn't there at all. All I can surmise is that I vaped the burnt portions. Again, this would be nothing in comparison to the amount of paper I've smoked over the years.

Coil in question is about 1.5 mm, .5 ohm, 28 ga ... no crazy watts, just cheap mech mods. Straight drops from 4.2 to about 3.5 volts.

Did one test build to see what it would take to set it on fire on another device (yeah, we're allowed to do it) ... Its not that hard is all I can say. Compared it with cotton. Much easier to clean up. Actually the cotton made me pitch the coil as I didn't/wont try and get that carbon off.

Sorry no pics, I never think about them when I'm doing this stuff.

Has been used in 7 devices so far. No major issues cept the break in tasting awful to me. Not just coil tasting. Closer to the dry hit. Which after some playing around I think is just all the micro fibers burning off on the coil at first.


Just some random feedback on the potential breakdown aspect of the material over time. Not a health worry note at all for those who skim, just that the material may breakdown and should be tested for this as part of the analysis on your setups/juices.

Need a control now of a pure VG, no nic setup. Need a matching RDA, mod, etc first.

 

[JimzDogz]

Lets not get too defensive when people inquire about safety. I'm sure they are only concerned about their health and ours. I know it can be frustrating having the same questions posed and the same skepticisms voiced repeatedly. But new things are sometimes scary and some folks just need a little more assuring than others.

Probably should have changed the wick after the free fire.

Rayon is known to biodegrade faster than cotton. But holds up to things such as bleach and other chemicals better than cotton. I even saw a rayon cloth for use in aircraft work. It's possible that Acid could attack the fiber I would have to look into it. But being that you dry burned the wick we can't make a determination.

 

[Jdbaker82]

Nah, nobody has given any thought to that at all. Nobody in this thread bothered to read the thread and just went for it.

that's what it looks like to me just a little research tells me this stuff is very toxic....
