Careful!  These may not be the best scarf material.  They might be carcinogenic.

Well it seems to compare them to asbestos.  And asbestos is only dangerous in a powder form.  Such a scarf would be made of long threads so you're not likely to inhale something dangerous.

Surgoshan:
Except that microscopic particles of asbestos escape from the material it's made of, which is a possibility with a thread of nanofiber.

However, carbon nanotubes are, at the moment, still only being considered for microchip purposes, as I understand it.  I don't think anyone's made a nanotube even microns long, let alone long enough to weave into yarn.

Is it cold in here?:
Last year some University of Cincinnati researchers announced having created nanotubes almost two centimeters long.

You are now free to call me a nerd.

Surgoshan:
That is impressive.  Weavable?  Because if they can be woven, we're talking space elevators.
