I have similar photos from Stephen Birkett's website. They show quite clearly that the fibers are not, in fact, hollow, at least to my eye. The link from the wiki article on wool, saying its fibers are hollow, sends you to a web page that does, indeed, say that Angora wool (rabbit) fibers are hollow. I was unable to see any evidence on that page to back up the statement with respect to sheep's wool. I saw various references in various places to the fact that the interior of the fibers absorbs water, up to 30% by weight, stuff I had read about before. Reasons why wool clothes were used so much, to keep you warm even in the wet. Regards, Fred Sturm fssturm at unm.edu "Travel is fatal to prejudice, bigotry, and narrow-mindedness."
