An animal fiber that tribal weavers sometimes use for a rug's foundation in place of wool, as in Gabbeh and Quchan rugs, while the pile itself stays wool. Together with mohair, camel hair and cow hair it is among the less common rug materials, seen mostly in tribal work, and it also turns up in some flat-woven kilims.
The long, silky, lustrous hair of the Angora goat. In Persian rugs it is one of several animal fibers, listed together with goat hair, camel hair and cow hair, that can serve as a material but are much less common than the usual wool, cotton and silk; this group is seen mostly in tribal rugs.
