i really wanted to buy a bunch of rayon, but it seems really hard to get hold of over here in the UK, i found someone on ebay selling the balls that you speak of Jeremy, it said TIDI whatever that means, apart from that i could only find clothes made from it or swab's, are there any other country's closer to the UK that do it? that ebay one i found is $24 for a bag of 1000 i think! and then $35 for postage...
i did have the top man sedge send me a envelope of it(thankyou sedge) but it's not the same as when you can waste as much as you like..

i dont know if this has any good info for anyone, but i found this on my journeys through the web, some interesting stuff >>Viscose rayon - the oldest man made fiber - versatile fiber yarn

i liked what was said in the summary of that page

Mm? Did anyone ever do a vape comparison between the Sally's and delasco rayon?

Kiwi,

If it is Rayon Jeremy has tried it and I believe he recommends the Delasco because it is more uniform and no one so far has used it and complained of any bad taste. The Sally stuff comes in a plastic bag in a box but is not sealed.

Just wondering if those CE3 may benefit from a low(er)-res coil when wicking with rayon on stick batteries..
After working with rayon, CC from Sally's, and Tencel in my little CE3 micro tanks for a few days I've come to the conclusion that rayon won't work well in the CE3. The Tencel does a pretty good job though. The problem is not a "fault" of rayon, but more of a direct result of how well it wicks. The CE3 is normally used on a stick battery so there is no way to up the power to handle the added amount of liquid that rayon provides to the coil. (..)

Yeah, "derp!" means exactly what you think it means, in that it's the internal noise a person (well, me anyway, ever since I heard my brother say it out loud, heh) makes when they goof up.
;)


I don't know what "Derp" means but if it is anything close to what I think it means that is about how I would feel in your shoes.

I'm coming to the conclusion that boiling rayon may get things worse..

I was not having a stellar experience with rayon (boiled for some 30+ mins) until today just for kicks I've tried the same rayon 'au naturel'.. Very different story, and appreciably better results.

Possibly due to scrambled fibers, who knows, but boiled rayon seems much closer to cotton, performance wise. Still testing it, we'll see in a couple days.

Just keep in mind that Rayon specs state that is starts to break down at temperatures of 200 F and above. At 212 F I would imagine that the cellulous fiber chains start to break about and will approach the characteristics of Cotton.

Are you boil it for health concern or taste? In either case just rinsing it with warm tap water should do it.

For what it is worth I don't clean mine at all. As far as bad taste I have not experienced that. Actually yesterday I took a one inch piece right off the roll and chewed it like bubblegum for about five minutes and never did taste anything and certainly nothing more than what you taste when the Dentist packs your mouth with those cotton/rayon (whatever) rolls.

I'm really wondering if the bad taste issue some folks are getting is because the box isn't sealed in any way and there are all sorts of nasty chemicals used in the beauty shop. Simple cross contamination. So the poor sod who gets a box that's been in the path of something gets weird tastes but most get lucky and get a reasonably clean box.

Sitting down, facing forward.
Just wondering if those CE3 may benefit from a low(er)-res coil when wicking with rayon on stick batteries..

The lower the coil resistance the lower the performance from the battery. Keep in mind these batteries are 280mah at best and probably down around 200mah. When the load hits, I'm betting voltage is dropping down to 3.0 to 3.5 at best. A lower resistance coil will only make that worse. One of these days when I have nothing else to do I do want to build an "inline" adapter for these stick batteries so I can monitor current and voltage with meters instead of just guessing.

Ouch, I see.. My ego sticks from a couple years ago were in the 1Ah (nominal) neighborhood, hence the suggestion LOL

I would tend to agree with this, but it would be on a store by store basis because everything else in there is sealed for the most part, so it would depend on how many people are testing hairsprays and spilling other stuff in the store. I got mine in a pretty small Sally's that doesn't get much traffic at all, and I haven't had any problems with flavor yet.

I've been messing with Rayon for about two weeks now and while i do love it for the advantages posted in this thread the wick density is very hit or miss for me. I didn't have time to wait an hour each time for the wick to break in and honestly got real tired of opening up my kayfuns every hour to check and/or redo the wick. So i tried rolling the rayon tight instead of leaving it loose before i inserted it into the coil. I did not wet it like tencel (too messy) and i did not twist it. I just rolled it with my forefinger, middle finger, and thumb, using both hands and squeezing pretty tight until it was the same size as the coil. If it was still too thick after rolling i stretched it a little and re-rolled. After wetting, the wick has very very slight shoulders, pretty much the same size as the coil. This has worked well for me so far. After a 1.5 days of use in drippers and kayfun the wick looks to be the same width as when i first inserted it, no shrinking or expending. Coils are clean and no darkening of the wick. Wicking action seems better too but that is probably because i was using too much before.

I know this is not the consensus on how to wick Rayon but this just seems to work better for me. I was never good at cotton balls/roll either because of inconsistent density. This is why I loved KGD cotton so much. It comes in sheets so all you have to do is cut a strip the same size as your coil and you are done. Now with Ryon i just roll tight to the same size as coil and i'm done. Couldn't do this with cotton balls/roll because it would expand.

kojul,

My situation is the same as yours small store, no bad taste, actually no taste at all. However they do keep them on the lowest shelf in the store and I had to pick the box from the back of the shelf because the next one up looked like some drove over it with a truck.

Also you never know how long the stuff has been sitting in the warehouse. Most small stores don't like filling up their shelves with such giant boxes that sell for less than a two ounce bottle of hair dye. ;)

OK - maybe not a truck but it was really beat-up.

So, quick question - still playing around with the rayon, and still getting mixed results.

The awful flavor (would now say it's primarily a very bitter flavor, with some acridity as well) seemed to go away after a couple of mls, and the wicking was solid to the last drop.

Just did an A-B test using the same coil, same juice, same setup (to ensure it wasn't the coil or juice or anything), boiled organic cotton and unboiled CC straight off the roll, and the rayon definitely has a bitter, acrid flavor the cotton does not have.

When I first started using cotton, I didn't like the flavor at all, either, until I boiled it twice. Now I get nothing but clean flavor from the boiled cotton.

So my question is for those of you using CC without boiling - when you were using cotton, did you give it a good, long boil before using, or did you just wick it unboiled? Maybe the difference is that I'm just more sensitive to all wick materials. Couldn't use cotton without boiling, and the same may be true for rayon...

I noticed today my dripper was just not letting the menthol through in this peach menthol I vape, rewicked and bam....in your face menthol again.

I had ran about 8ml through it before the flavor tapered off, I think boiling the wick would degrade the flavor performance of rayon.

I haven't tried it boiled but I assume boiling it would be similar to running a lot of juice through it.

I should also mention that, once it breaks in, the flavor seems similar to cotton, but the wicking ability of rayon is much better. More flow, less absorption = less wasted juice! The rayon seems to last a lot longer than cotton, also.

And you can chain-vape it at higher power (though not necessary) with no dry hits. :)

If I could just get rid of the bitterness... :(

ultimately the pharmy balls will most likely be the cleanest route. No need to boil those. I'm still waiting for reports from those that placed orders with the two different suppliers mentioned in this thread. I'm currently using Sally's, but that just because I could shoot up the road and get it.
