The tencil and the alpaca look like yarn.. anyone know if they are manageable to use/unroll.. not use a specific coil diameter?
They sell the loose fiber

Thanks for the info, Bob. I have been using the rayon for a day now, and am really liking how it performs across the board. However, I am going to rewick with cotton and wait for my tencel to arrive. While we are all certainly guinea pigs as vapers, that blurb about the processing agents used in the production of rayon is enough to make me not want to use it. The tencel, from what I've gathered, goes through the same process, however is more 'eco-friendly'. That is, the process itself, what remains in the fibers is my concern. The tencel is gonna get a nice boil and dry before I use it, if I use it. Still very interested in the topic and the opinions and experience concerning the usage of these cotton alternatives.
Not sure if I would say the same chemicals are used because the whole basis of lyocell is use of non toxic amine acid solvents in the processing.
The only mentions I've found of this emitting chemicals is the parroting of that bashwar article. Which I believe is an over exagerated claim because no other claim can be found and the claimed chemical evaporates at room temperature. So I guess if you handlers it right out of mfg you may be exposed. A week later I'm guessing no trace of it.

In the TENCEL® production process (which is patented by the Lenzig Group) a non-toxic solvent which belongs to the amine oxide family is used. Close to 100% of the solvent is recovered in this production.60
Pg9 re: traditional rayon - the exposure risk is in manufacturing
"These chemicals do not remain as a residue on the fibers – the proof of this is that almost all of the viscose produced can be (and often is) Oeko Tex certified (which certifies that the finished fiber has been tested for any chemicals which may be harmful to a person’s health and contains no trace of these chemicals.)
The problem comes in disposing of these process chemicals: the sodium hydroxide *(though not harmful to humans) is nevertheless harmful to the environment if dumped into our rivers as untreated effluent. Same with carbon disulphide and, certainly, sulphuric acid. Oeko Tex certifies only the final product, i.e., the fibres or the fabric. They do not look at the production process, which can be devastating.“24"
Re: cotton pg 11
The cotton production uses 16% of the world’s insecticide consumption. This is more than any other single crop. And a lot of these chemicals run into our waterways, harming both humans and the natural environment.
Typical source of cellulose for this process is wood (like oak or birch), but also eucalyptus. Eucalyptus is a preferred source because it grows fast and thick on low-grade land, and is considered more sustainable.
