I'm seeking a {brand} name for the protective sock that goes inside polyethylene fiber duct. It's a woven hollow tube; you pull in say 6 of them, then the fiber is pulled down the middle of each sock. This not only protects fiber from abrasion but also tangles with adjacent fiber bundles.
I can picture it, but my Googlefu is weak, and I can't find a noun, brand name or supplier.
