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

[mnealtx]

Rewicked yesterday, wick that was inside of coil was pretty dark and coil was gunked up. Longer tails this time...

24 hours later.... vapor is thin again.

Going to try less in the coil and keep the tails.

Ugh...this is worse than cotton trying to find the right amount..re-reading the thread to find the recommendations about amount...

I'm *not* twisting it except enough to get it threaded into the coil. Pull tension on the strands, work until just a bit snug.

Juiced it up and (for first time) waiting to see what happens with the wick as it sits in the coil. The 'feeding side' (side I fed the wick into) has just a bit of a shoulder - could just be it's more 'poofy'. The 'fed side' (side the wick came out) has no shoulder, appears to fill the coil.

15 minutes later: No sag... gonna button it up and cross my fingers. Dropped power down to 9.5-10w

As of today, 25 people in the UK have been sent or are about to receive a rayon sample from me, I'm closing the offer now. Only because I'm knackered from scribbling addresses on jiffys and ferrying them off to the post office Share the rayon folks, let's get the word out of this great stuff.

That's very nice of you to share with so many. At least a few folks in the UK will get to try rayon.

Provided as a FYI only...

Was listening to modenvy, the weekly Vapor Joe's giveaway net broadcast, and they mentioned using rayon for wicks. Pretty much dissed it. VJ said for example what if someone in China went down to a local store and bought rayon, who knows what's in it. The whole caustic chemicals used in the making of it and how cotton is so pure, etc. Basically the silliness mentioned here that was easily rebutted.

Just wanted to say Hi and thank you all for compiling this nearly absurd amount of information. I've been lurking through here for quite awhile and the amount of research in this thread is truly impressive, and I thank you very much for doing it for me.

I received a sample of the sally's from another member, and then finally received my tidi rayon balls last night.
I couldn't be happier with the rayon.

The taste of my favorite liquids is even better.
I have found with one flavor I was disappointed I didn't like (hated in fact), decided to give it one more try on rayon before I traded it....Holy cow, it's delicious on rayon.
I'm clearly vaping a larger volume of liquid, without vaping more often. Probably ought to cut the nic back, b/c vaping less just won't happen.
Whoever said the vapor appears more like smoke - I agree with that 100%

But the biggest plus for me, is how long it lasts. I'm a lazy vapor, rewicking cotton all the time was making me a grumpy gal and there were times I wished for the ease of just buying a new pack of smokes. I abused my first protank (don't laugh, I love them for out and about) with dark sweet NETs. I couldn't believe it was still going strong after 8 tanks and had to pull it apart just to see what was going on in there. Rinsed it out, pure white with just a tiny amount of discoloration in the middle. On cotton the same liquids were completely gunked up to physically unvapable by 3 maybe 4 tanks.

I just got the tidi balls, but my first impression was that they're cleaner, tasting/smelling, especially those first couple of drags. This could all be in my head though, as that was the exact reason I was leery of buying the Sally's to begin with.

Anyways, Thank you all!!
(i do have a small mountain of them...if anyone was wanting to try the tidi balls...let me know)

R91% on provari, 1/16th ID coil at 2.1 ohms, 10 watts. Wick is pretty snug when stretched to feed it into the coil. Slight shoulder on the insertion side, but after the exit from the coil. After wetting the rayon, no shoulders and no sag. Tails trimmed equal to outside diameter of the mod, stuffed into deck touching the inside of the chimney to prevent hard bend in the wick.

What I want: The dense, moist, lung-filling hits I get when I first build the wick and juice it up.

What I got, 4 hours later: Thin, tasteless vapor.

Vapor delivery was great until it started feeding from the tank vs. what was on the wick. Gotta be something with delivery...but *what*?

Very tempted to build a 3/32 ID coil and see if that's any better for liquid delivery.

Edit: Trying this one last time with the Tencel top... wicked like cotton, just a hint of drag through the coil.

So I guess I was mistaken when I said they don't carry the CelluCotton Rayon at my Sally's. It's in a whole other spot than the rest of it, in my defense. And it only came in the HUGE boxes. There was 2 different huge ones... I got the smaller of the two and it's still insane. You guys weren't lying. Either way, I'm set for wick for a while.

Lying? I think pretty much everyone was saying one box and you're pretty well good for the rest of your life...

I meant, weren't lying. My bad.

 

[mykereid]

I think some of the problems are related to the juice you use with it. I've had problems with a 67PG/33VG mix, but all other combinations I've tried (mostly 50/50) have worked great.

So what's the trick with cc and kayfuns? I keep getting dry hits.

I found out how durable the rayon really is today, I set my Nemesis down unlocked...when I picked it up it had already stopped firing but was still quite hot, the battery was dead and the Kayfun was empty. I disassembled the KF apart expecting to find a pretty nasty wick, but to my surprise the rayon showed no discoloration or any sign of burning...pretty much looked like any other slightly used rayon build...pretty tough stuff.

No worries - confused me for a minute, is all.

You can do like other folks have mentioned and leave whatever is left to your kids as part of your estate....

Thanks for sorting this out for me gents.

I did the same thing, same experience as well except my battery wasn't dead and the Russian wasn't empty. Device was so hot it burned my hand when I picked it up.

I posted about it somewhere in this thread.

So rayon seems like it's really exploding next to Japanese cotton. Anyone compared the two?

What's the safety consensus with rayon?

Whenever I read uninformed crap like this I reply with Jeremy's Oeko-Tex Post. It's what sold me on trying it in the first place. Unfortunately many people like this guy VJ wouldn't bother to dig through this 300 + page thread for info. That post also talks about how organic cotton is approved to be processed with sodium hydroxide. So the "purity" claim is somewhat moot when you also consider how it is grown too.

Also, "people in China" buy Rayon regularly assuming women exist there. Last time I checked, women in China also need Tampons brah.

I don't know my chemistry, but if Sodium hydroxide, carbon disulfide, and sulfuric acid are found on the finished Rayon product, wouldn't women be having more trouble down there? There may be better reasons for me to put faith into Oeko-Tex's claim that the finished product does not contain traces of these chemicals. Although for a simpleton like me it makes sense.

I've tried both. I've personally found nothing special about the Japanese cotton... and I love all things Asian.

This may or may not be interesting, just putting it out there.

I changed the rayon in my Origen. What's of note is that these both came out of the same atty, same (colored, amber colored) juice, same life-span, both (vertical) coils combined giving 0.69 ohm, and each one being the same resistance of about 1.4 ohms). I knew that one coil had more rayon in it, and although it worked fine, I wanted to see what the effect was.

After a quick rince:

Although it is not "scorched" by any means - and I did have a few almost bone-dry hits - there is a bit more coloring on the bigger wick (wicks are still wet from the rinse BTW). Not sure if it proves anything, but for me I now went with "smaller" wicks like the top one.

Also, for people having trouble with Kayfuns/Russians: I make sure the coil itself has enough rayon, but I do cut the hanging part into a V down to the deck, so that there's just a small area touching the deck, and I also make sure it is stuck to the inside wall, and at no point blocks or even obscures (view from top with half chimney on) the juice channels. Theory behind it is that a) you do need to touch all sides of the coils (I use 3mm coils), but because it wicks so fast, you don't need a lot picking up the liquid. I am using 60/40 ish VG/PG, and I do make sure I don't totally overfill (leaving a good air bubble) and create a vacuum from the start by having a few tokes without firing. After that, I can not create a single dry hit or gurgling, even with 15 second drags. This is both with the original kfl+, two ehpro clones, and a Kebo Russian91.

Another thing: the outside of the coils stays much cleaner/shinier, like they had just been installed, and cleaner than after a dry-burn. I suppose it's similar to what happens (or doesn't happen) inside the coils.

Finally, and this may not be a rayon but a Sally's thing: I decided to boil it in batches (d'oh), as I don't know in what environment the "open" boxes have been stored.

I believe Pbusardo is suppose to be reviewing Rayon, Japanese Cotton and several other wicking material this week to see which is the best. His buddy Demetri just did a reviewed an innokin dripper and used rayon.
