Guanaco Fibre

Zoological Information

  • Lama guanicoe is commonly known as Guanaco.
  • It belongs to the family Camelidae.
  • Guanacos are artiodactyls of medium to large size, characterised by long necks and feet with two toes.
  • The lifespan of guanacos is 20-25 years.
  • In pre-Columbian cultures, guanacos were considered a source of meat and fibre.

Habitat and fibre production

  • Guanacos are semi-captive animals from the South America.
  • In the early 1530s, around 30-35 million guanacos were recorded residing on the South American continent.
  • Following that time frame, there was a significant decline in the guanaco population due to a gradual rise in hunting for both their meat and fleece.
  •  The guanaco was included in the CITES (Convention on International Trade in Endangered Species of Wild Flora and Fauna). Consequently, following this designation, guanaco fibre was acquired by capturing them passively during the shearing season and subsequently releasing them.
  • These wild animals live in dry, semi-dry, mountainous regions of the South American continent, such as Peru, Bolivia, Ecuador, Colombia, Chile, and Argentina.
  • The annual production of guanaco hair fibres is around 1.5-2 tons and the yield per animal is up to 0.7-1 kg.
  • It has two layers of coat known as guard hair and inner coat.
  • The guard hairs are coarser and thick, and the inner hair fibres are fine and soft.

Features

  • The physical structure of the guanaco hair fibres makes it look soft and lustrous giving it a high visual appeal.
  • Its colour varies slightly, spanning from light brown to dark cinnamon and obtaining fibres of a faint grey to white from the neck to the stomach area.
  • The fleece is incredibly soft and smooth, containing 10-20% beard hairs and 50% medullated fibres, which means they have a central hollow or pithy core.
  • It has fewer scales than sheep’s wool.
  • It is much softer, less scratchy, and easy to handle.
  • It is three times warmer than wool and is finer than cashmere.
  • It does not shrink during washing or processing.
  • After the undercoat is spun, the high-quality fibre surpasses alpaca and ranks just below pure vicuna fibre in terms of quality.
