Not really. After I install the wick in the coil I blow off all loose stuff. Once it gets wet with juice I never have a problem with fraying.
Is no one worried about using this stuff even after boiling the one I bought when i touch it it leaves fibers all over my fingers when you cut it you can see them flying everywhere so my question is wouldn't we be inhaling this stuff? It's a nice wick don't get me wrong I get really good flavor from it but my koh gen doh gives me just as good flavor and holds way more juice I'm not here to argue with anyone I'm just looking for answers because I do like using it but I'm just worried about those fibers

Hi Mike, I don't think you have anything to worry about; but, I don't want you to take my word for it. More on this later. I've written quite a bit about this material with pointers to previous research by others when interest in this media first started last year.
Just curious though where did you hear that this material had to be boiled?
One thing you shouldn't do if you're concerned about small particles is torch it before use. This will certainly dry the material excessively and if incorrectly torched damage the media fraying it and producing the very particles you're talking about.
Secondly, is it treated or cleaned?
Let us know won't you?
I'll fill you in as you come back.
Good luck.

But if you do not torch it beforehand the ends fray excessively when you cut them? And then you cannot cut one end to a point to screw into the coil? Or am I missing something?
Mat I have experienced what you're talking about on many occasions. No you're reading right, lol. Not going nuts.
The good news is that unless the entire length of the media was exposed to moisture or excessive heating cutting a little bit away at a time generally leads you to a pristine section within an inch or so. Because usually it's moisture absorption through capillary action that causes this. And I suspect that's the cause too with overheating by torching which induces the media to breathe as it rapidly afterward cools. Any significant environmental moisture will be absorbed.
As Tim noted above then properly prepared Nextel does not fray. No further desiccation is required. It's already been kilned so practically all of the air has been evacuated from within the fiber channels. Further heating particularly in the hot (blue, 1800 deg. F) zone of a torch can damage the fibers themselves breaking them. Then you'll see a lot of particulates and yes, fraying. Now you may also mean splaying which is the de-winding of the weave. Over-dessication as well may be the reason moisture exposure has caused the tip of the media to swell loosening the weave. Then delamination of the weave may happen easily. You don't want to moisten Nextel with water but PG or preferably VG and in the process of vaping as the best way to cure this material. If you're going to moisten it at all do it with the juice you'll be vaping. However, typically it should not be necessary.
RxW slim for example can be a bit difficult to feed into 1/16". There may be slight variation in kilning and you get some splaying. Usually a narrow flat head screw driver may be used to tuck some of the splays into the coil (in the direction of rotation). Once a few get in there a little pressure as you rotate is usually adequate for the wick to proceed with the tucked ends just folding back on the wick as they proceed.
There is no other media available to vapers that behaves anything like this providing the necessary rigidity to conform to a proper coil. By this I mean one with the geometry and resistance value appropriate to its flow potential. Usually a slight deflection fit (a bit smaller than it's wet diameter). It is worth every moment spent trying to improve our methods of introduction of this media into such a coil.
Now if you despite all this can get it fed, you may find that it will eventually break in and perform. Most of the experiences I have had though with Nextel under-performing compared to cotton has been because of overheating or moisture exposure. If the kilning was done as specified and carefully as per 3M's recommendations ceramic just shines.
A sealed glass or aluminum container that's airtight is the best preservation solution as soon as you receive this media. Try not to handle it except after carefully washing and drying hands. Alcohol towelettes are excellent for this purpose as long as they're not perfumed. Just always remember that this material is extremely absorbent at the ends.
Good luck M.

mactechvpr - question. What is your opinion on the small difference between the coil being 1/16 vs.16 gauge leur needle? I use 2mm wick and the 16 gauge works well and have no problem threading thru but I was wondering if there is a perfomance difference. If so I will be more patient and thread thru a 1/16 coil if you think the smaller diameter would make better contact with the wick producing difference in flavor .
Your thoughts always appreciated!

I think it does make a difference because every other coil diameter I've tried besides 1/16 has gave me a nasty taste I think when the coil makes contact with the wick it's heating up the wick as well and that way the wick is vaporizing juice along with the coil for better flavor and more vapor I use ready x in my drippers lately and I found this to be the best setup for me I can fill up my juice well and it will vaporize all the juice in it super consistent no dry hits at all until the juice is gone 9 wrap micro coil 24guage on a 1/16th big but I angle the coils to help readyx wick better and I tuck the tails that are touching the deck kinda in between the post so they stay put it really works well View attachment 365493
Rudy, good point…the needle saved me! LOL Really, watchin' video's by vapdivrr and others last Spring making tight near contact and contact coils inspired me to quit and get to it, perfecting them.
When I did, I developed an obvious preference for anything with a good hand hold. Because as you know I recommend straining coils into adhesion with tension as a means to improve their performance and efficiency.
So, no. Not a terribly big difference between a 16th and 16 needle gauge. I would say, that both may be useful for different juices, vg/pg ratios. Experimenting with tightening the wind for better vapor is what it's all about. And it's not impossible to use that needle in a pin vise (just secure the pointy end). So if you have a few sizes you're in good shape. Keep on using your existing wind. How's that?
First and foremose I promote the technique because I know it cures a host of sins (electrically speaking) like the propensity of shorts (loose turns, legs, etc.). The very things that wreck our vape.
So have at it. Modifying resistance (temperature) is what this game's about. Knowing wind diameters makes it easier to predict and duplicate tomorrow. Just like the dial on the stove.
Have fun and good luck!

Thanks for the input Mac!
What I like about the 16g luer needle is I can hold the plastic end with my thumb & forefinger and wedge the wire right up against the lip of where the needle meets the plastic and secure it under my thumb serving as a "vice" allowing me to keep nice tension on the wraps. No "jig" needed!I come out at the same ohm reading every time. Like you said a consistent matrix point is a must, then adjustments can be made from there based on juice, flavor, vape volume etc. to suit personal preference.

Interesting!! I have never had an odd taste using RxW. I just screw it into the coil and give it a couple squonks and its ready to vape. It seems to soak up the juice very fast for me. Maybe its because I only use little 1/2" pieces in my coils. Never had to soak it, let it sit, or anything like that. I think that is part of the reason this stuff is the best, IMO....
Its even better in a BC clearo with a coil that takes advantage of it, it's explosive.

Good luck.
