Rayon question...

[smizak]

I've started to use rayon and I've come across a term you guys use that I'm not sure about.

When you say you "thin the tails out 90%" does that mean removing wick material or simply fluffing them out?

thanx doodz

Thin or trim is done only on certain devices. To much cotton can sometimes block the holes, so its best to cut the ends of the cotton to a pointy(ish) profile. Percentage of removal is up to you to experiment with.

Removing wick material. With cotton you can pluck it out with a tweezer. Not sure about rayon though. It’s got fibersof arbitrary length

Sometimes, both. You want the wick packed tight in the coil, and if you have an RTA you need enough wick to block the juice from flooding the chamber. If you use a dripper, though, you really only need a very few, like sometimes half a dozen individual strands actually touching the deck for sufficient juice transport. The remaining 50-90% can be trimmed away right where it would otherwise bend downward toward the deck. Let me see if I can find you a picture of what I mean.

...(Edit) here is a good one from the Rayon thread:

Thanks y'all. I just fluffed it out and put a little bump on the coil ends and seems to be working well. I'm using a Smok TFV8 RBA/velocity style. I got some dry hits the last wicking when I pushed the tails straight down into the juice wells. I dig the pointed approach, will try that next.

It amazing how thin the tails are. Kinda defies logic but I've got 500ft of Cellucotton so no worries, I'll give it a shot

Yeh, but somehow it still works.

Thinning tails works (often times more with rayon) because you need your wick to have good capillary action. To thick tails will often wick less efficiently, leading to inconstant or even dry hits. A thinner wick allows the fibers to move juice to the coils more efficiently is how I understand it. Rayon shrinks when wet, so even more so, you want to be thinning, trimming on the diagonal etc. because you need your rayon tighter in the coil compared to cotton, so you will have more to trim.

I was fairly certain all my rayon builds would leak, but they didn't. Tight enough in the coil seems to do the trick. You'll get a sense for it. I use the stainless steel tweezers to thin and keep a finger on my coil so I don't pull the wick out. I will also often trim and thin AFTER I've moistened the wick with eliquid. It's messier, but it can work quite well.

Yeah, the LACK of leaking with rayon is absolutely SHOCKING. I was overwicking at first (my particular tendency) and the wick was breaking in the coil, so I had to consciously dial it back a bit, thinking the whole time, "This build's gonna leak" and it just didn't.

Best of luck,
Anna

[...] Rayon swells when wet [...]

Err...cotton expands when wet. Rayon, not so much, I thought. I was under the impression that that is why we pack it soo tight in the coil (hence, the need for thinning of the tails), because if anything, it actually compresses or perhaps just "settles" a bit once you juice it.

 

[Beamslider]

I don't thin out rayon as I found it didn't work well for me in Toptank RBA. I cut it in a triangle shape and that does sort of thin it at the bottom and it works great

No you are correct it's cotton that swells, rayon shrinks. I'll go back and edit that post (not enough coffee apparently). LOL.

Thanks for the advice homies. I re-wicked and thinned the tails while keeping a bit just off the end of the coil. What a difference, had to crank up the power to handle the amount of juice getting to the coil. No leaking, huge clouds, huge flavor.

Very good intro in this link. Got me thinking again. Thanks for that.

 

[cheech226]

i cut about 75% of the wick after it leaves the coil. i was stubborn at first and now that i do this it wicks sooo much better

 

[DaveP]

When I install the wick in the coil the tails fan out after I cut them to just touch the deck. I trim the tails with scissors to match the width of the coil on all sides (top, bottom, left, and right). That seems to work fine for my 2.5mm coils. Air flow isn't restricted and there's plenty of juice feed for my 10W coils.

I suppose I could go smaller after listening to some describe their really thin tails.

 

[stols001]

If it's working.... ?? Because one person's really thin is another person's rather thick.

There is a joke in there that I just refuse to make. LOL.
