Cashmere is a type of wool that is made from the cashmere fibers of the Cashmere goat, which is native to the high plateaus of Central Asia. The cashmere fibers are collected from the undercoat of the goat, which grows during the winter months to keep the animal warm. The cashmere fibers are then spun into yarn and used to create a variety of clothing and accessories, including sweaters, scarves, shawls, and blankets.

The use of cashmere wool can be traced back to ancient civilizations in Central Asia, where it was prized for its warmth and softness. In the 19th century, cashmere became more widely available and was exported to Europe and North America, where it became a popular material for high-end clothing and accessories. Today, cashmere is still considered a luxury fabric and is prized for its softness and durability.
