What are you trying to make with the Zorb. I too looked it up and it looks as though it can be used as a diaper liner too. I can't tell from pictures just how thick it is. It does seem to be quite absorbent. I would think however that the fibers are getting stuck in you mat because it is not a woven fabric. I would brush you mat well and wash out the fibers gently. I would also clean out your blades from the fibers that can collect in there.
