Whilst the Cashmere Goat and the Yak are shorn, the camel sheds its fleece to be gathered. The most important aspect of the production of Cashmere, Yak or Camelhair production is the dehairing process. Up to 60% of the raw fibre is what is called 'Guard Hair", this is the outer layer of hair that protects the animals from their environment. The fibres we refer to as Cashmere, Yak or Camel in yarn terms is in fact the innermost fleece, there to keep the animal warm. The outer Guard hair thus has to be separated from the inner fleece though an extensive mechanical carding process.
