How effectively can you spin carbon fiber into a thread?
I need a thread I can use in a sewing machine with as high tensile strength as possible, and my idea was to use carbon fiber roving. However, I'm not sure how I'm going to turn the thousands of individual strands into a single thread. If I used methods used on wool like a drop spindle, would the thread unwind immediately? Am I going to have to use a coating? There is plenty of information on how to spin wool, but little on synthetic fiber.

Why don't you buy industrial Kevlar thread?
I doubt you can spin it as well in your home shop and if you need "as high tensile strenght as possible" that's certainly not a solution.

Plus some new scissors.

Kevlar generally has lower tensile strength which is why I looked at Tenax first, but I might take a look and see what I can get.

Again, if you need as high tensile strength as possible I don't see how you can even consider a diy-option. I doubt you could get the necessary fabrication setup to even reach tensile strength of commercial polyester or nylon thread; not to mention reaching a substantial _consistency_ -- which certainly will be the most important aspect of your diy-thread in terms of strength. Without consistency and quality control, it will just fail at the weakest point, and then you might as well take a weaker thread and use a better sewing solution (i.e. bartacks or whatever).

Use dyneema

DENIED. ask us for help with the root problem, shithead.

Most of the fibers that can be made into a thread/yarn need to be added to grease wool in order to hold them together properly. If the fibers are long enough you can use standard cordage making techniques. If you want to purchase something instead of making it, you can try some Dyneema. It is used to make bow strings and is easy to work with, but extremely strong. You can also purchase Dyneema sewing thread (sk75).

There's a section about adding fibers to wool or making yarn from different fibers. I think google books has the 2012 version scanned. Chapter II Preparing the Fiber for Spinning. I'm, sure other yarnmaking books can also help with unusual fibers.

I have some for fly tying. Man, that shit is hard to cut. Dyneema is better for weight to strength ratio and Kevlar is only a tiny bit better for tensile strength by only a few pounds. Dyneema is super easy to work with.

You need to strach break it first, then twist it, then spin it and cost it.
Source - we make 2k filament CF threads.

Shit is hard to set up but doable

I'm a spinner and this question is deadass blowing my mind a bit. I would imagine you might be able to work it on a wheel with a high enough ratio but I doubt a spindle would get you enough twist or have enough efficiency to be able to spin it effectively. then again I've never touched carbon fiber, I'm assuming it would be somewhat like spinning silk since silk is extremely fine and slippery without the crimp that makes wool fairly grabby and easy to spin.

Why not just get carbon fiber yarn?
