Cashmere is a particularly rare valuable fibre. Yearly production is only 5 million kilos throughout the world.

Cashmere fibres are obtained from the fleece of a species of goat, commonly known as cashmere goats, which are bred in countries such as Iran, Russia, Afghanistan, Turkey and India. The most beautiful and prized cashmere comes from the high plains of Chinese Inner Mongolia: a harsh land with (an) extremely cold climate. Inner Mongolia Cashmere is distinguished by the fineness of the fibres (14-15 ยต) and their length and uniformity, as well as their particularly soft hand.

To protect themselves from the extreme cold cashmere goats have two coats: a top one made up of thick hairs and one next to the skin, made up of short down, very fine and warm, known as duvet. In spring the shepherds first cut the external coat with shears then collect the finer part with special long-toothed combs. The fibres from the two coats are then separated because only the duvet is actual cashmere.
