The hair of the vicuña is sheared in pens after a traditional roundup ("chaccu"). [8] A wool with an average fiber length of 2–4 cm is obtained every other year. The weight of shorn wool hairs per animal is about 250 g every two years [9] to 450 g, [1] after removal of unwanted guard hairs from the down hair. [1]
The vicuña (Lama vicugna) or vicuna [3] (both / v ɪ ˈ k uː n j ə /, very rarely spelled vicugna, its former genus name) [4] [5] is one of the two wild South American camelids, which live in the high alpine areas of the Andes; the other camelid is the guanaco, which lives at lower elevations.
Papuan women with kinky hair. Kinky hair is a uniquely human characteristic, as most mammals have straight hair, including the earliest hominids.

Camel hair has two components: guard hair and undercoat. Guard hair is the outer protective fur, which is coarse and inflexible and can be woven into haircloth. (Guard hair may be made softer and plusher by blending it with another fibre, especially wool.) The undercoat, which is shorter and finer than guard hair, is less protective but more ...
Qiviut is produced by the muskox's secondary hair follicles, which are not associated with sebaceous glands, and therefore is a much drier fibre than wool, having only about 7 percent oils. The hair follicle density is very high (approximately 42 mm 2 [0.065 sq in]) and qiviut is shed in a tightly synchronized spring moulting period. The qiviut ...
