What aspects of rayon did you find disagreeable? What is your 1st choice for wick material?
No, I always used cotton so guess I'm just used to it. I wanted to at least try the rayon, but didn't like how it vaped for me. I only used it once so may give it another go later on. I just like my cotton.

Whats awesome about rayon is this:
You know that tank that you need to stuff the wick holes with cotton to prevent a leak? But at that point the cotton won't wick?
Not so much with rayon. I wicked my griffin 25 down past the holes and to the bottom of the channel...big no no for the griffin but it worked. Why? Better material. You can stuff it tight and it will wick and you can get loose and it won't leak.

If you've tried it and didn't like it, you probably didn't use enough. I have to grab my coils with one hand and pull the rayon with the other to keep my legs straight. Either that or twist the entire piece to make it smaller and pull it.
Now that you have a giant wad of wick on either end you need to cut away every extra bit that you don't need to plug the channel. Getting rid of the excess will eliminate any taste of the rayon.

Whwn I first used it I looked at my tank and thought "Wow, that's what my juice tastes like!"

I've never tried rayon, so I have a question: what about leaking?
In my experience - more cotton is better. I mean 3 mm coil (even if I vape at 9 W) and long tails, so that chamber is mostly filled with cotton. When wicked in this manner, non of my tanks leaks, not at all (Kafun 4, 5, mini 3, Taifun GT2, Serpent Mini, Subtank). Can trimmed tails prevent leaks?
I have a couple Kayfun Lites and a Subtank Mini that I wick with rayon. For the Subtank, I trim it on a diagonal like this so it just loosely covers the holes in the chamber when I slide the barrel down on top of it:

It does cover the holes completely but only very loosely, it's not "packed" or "plugged" in any sense.

In the Kayfuns, I trim away the top maybe 60-70% of the thickness of the wick with a kind of "square" cut, horizontally almost right up to the coil and then trim it away with a vertical cut, leaving only a thin little tail which I then "glue" into place with a few drops of e-liquid before I screw on the barrel. The tails are sort of "plastered" to the side of the positive block and just barely brushing up against the deck, nowhere near the juice inlet channels and there is still plenty of open airspace inside the chamber.

I won't say "never" but I only rarely get any leaking this way and it usually seems to be caused by having the coil set down low too close to the airhole. Generally lifting it up by a hair and re-wicking in the same manner will solve the issue.

Agreed on the pack rayon tight technique combined with heavy haircut on tails. I trim with goal of hollowing center and leaving long strands on those contacting coil. IMO as MTL hitter, if coil is properly wicked and trimmed the loud sizzle and pops vanish and vape iis full while practically inaudible.

Hey,

It's counterintuitive when you've used cotton - but like I say, use so much in the coil you think it has to be too tight, and so little in the tails that you think it's got to leak.

Rayon can hold a leak with half, or less, the material of cotton. It holds the juice better. Using too much in the tails or on the deck will slow the feed of juice. Not only that, but rayon feeds the coil with juice faster so it need more juice flow. It doesn't absorb like a sponge(cotton) it transports juice to the coil. Ideally you use about the least amount needed in the tails to prevent leaking. Each atty is different it's all trial and error. 50% trim of the tail density is a good starting point if your lost.

Most cases of negative inclinations to rayon are due to improper use. Not enough rayon in the coil and or full cotton type tails.

There is a few day adjustment to the increased amount of atomized liquid particles. More base, nic, and flavor molecules are atomized. It's like you were in a cloud competition till you adjust. Rayon provides a wetter vapor with less burning. It is a different vape.

Having tried rayon for the first time about 3 weeks ago I am now using it exclusively and would be happy to give my stash of JC to anyone who wants it. I wick with rayon exactly like I wicked with JC. I don't try and to fit it in the coil tightly but when I do I don't worry about it because if it will fit it will work. Leaking with my RTA's has been less of a problem than with JC though maybe I'm just getting better at wicking is all. I can't tell if it wicks faster than JC but it certainly wicks as quick and dry hits have not been a problem at all. Finally and this was the selling point for me was that I detect no taste from it. My juices all seemed to taste better, cleaner, more flavorful. I even compared it to JC in the same type atty with the same juice at the same time and the lack of that typical cotton taste was noticeable and in fact I was surprised at how bad the JC actually tastes and how much it impacts the juice taste. Having started on JC I never noticed it before but like anything else now I can't not taste it so definitely no more JC for me.

If it's dense enough in the coil and the tails are trimmed right, you'll notice it wick faster.

If you put a blob of VG on cotton it will sit there for quite sone time. 5 seconds, maybe 10 before it's fully absorbed.
Do the same thing on rayon and it dissappears almost instantly.

If your coils are really dence with gobs of surface area and you chuck a ton of power at them, you can watch giant air bubbles shoot out of the juice holes right after you hit it. When I was using cotton it would be many smaller bubbles over several seconds.

If you do get a bit of a breakin taste then your atty is wicked wrong. The rayon doesn't expand like the cottons so you have to have it fairly snug in the coil. Rayon is great stuff especially after to remove it from the crispy cocooned coil and notice thats its still quite clean and not burnt, its a very robust wicking material.

Ever use Kotex Us?
Compared to Cellucotton it has a break in no matter how you use it but the fibers are much finer and it wicks crazy fast.
You can get around the taste by trimming the tails appropriately, priming them with juice and just let them sit over night.

If I cared enough, I'd boil them in distilled water in the crockpot over night.
Actually that might make them even fluffier...hmmm.

Ehh I've done extreemly tight wicking, relatively loose wicking, and in the middle with rayon.

I always seem to have the burnt bandaids taste for about 10-15 puffs. After that however, its flavor town.

But man that breakin flavor haunts my nightmares.

Try to put the deck on a mod and drip on the wire coil and pulse it briefly each time you drip to prime the wick from the center out. It will take a number of pulses to get it fully primed and those will be all those funky tasting first hits you would normally get if you just soaked the wick and stuck it in your tank.

This is with a squonk box actually. I just keep it completely submerged for probably 20 to 30 seconds.

I also just started using rayon several weeks ago and mixed on results. The wicking is phenominal compared to cotton and it is true that the tails have to be just right to prevent over or under wicking and you need to really stuff your coils, Thank you all for the tutorials and info. The problem I have run into after getting the wicking sorted out and dialed in is I have had to cut my nic down by 2/3 rds and my flavors in half. Even at this mix I can really taste my nic, sort of an aftertaste, not necessarily while taking a drag off my vape. I am vaping Vapor Tek premium at 3 mg. now and can still taste. Any body else getting this issue >? With cotton my nic was up to 15 mg. and had no taste, but I was using more flavor and maybe thats whats at work here. It just seemed like it tasted better with less flavor in the rayon wicked rtas but maybe higher flavor was really masking the nic.

I flavor at under 20% and my nic is 2mg.
I don't think we are using the same sort of builds if you were up to 15mg. But even using Nude Nicotine at 2mg, even on my bigger builds I can't taste the nic.
I've got to really turn things up to get a good TH.
Who is your Nicotine vendor?
With rayon I've found you need quality nic or the off taste is amplified.
I'd recommend Nude's Smooth line of nic salts.

I have been using STMs with .5 ohm rbas 10 - 15mg. and using Vapers Tek premium nic. My nicotine is 3 years old but kept frozen in proper 30 ml. bottles so should be fresh still. I have Nude nic in one of my freezers and will have to try that in few days and let you know if anybody is interested? It is Nude Armour version 2 I think with the argon gas added on top and is only a year old.
