Reviving wool from possible moth damage I tried hard to find a relevant stackexchange site for this question and this seemed closest. 

I have a wool winter jacket that has been stored over summer and on pulling it out of the closet I discovered what looks like, I am guessing, moth damage. See below:



There are no holes but it seems the “fluff” from the yarn on the herringbone has been removed. 

Is there any way to revive the wool and return the texture to the yarn?
A quick hack would be to roughen the bare patches up with an old toothbrush or the coarse side of a velcro strip. Try to treat only the bare patches like this and be extra careful at the edges between original and damaged cloth.

I doubt that you could restore the original properties of the cloth, but that rouch treatment should make the bare patches less noticeable.
