Background

The cashmere grows on the outer epidermal layer of the goat, is a thin layer of fine cashmere covered at the root of the goat coarse hair, grows out when the sunshine duration is reduced (autumn minutes), resists wind cold, falls off after the sunshine duration is increased (spring minutes), naturally adapts to the climate according to the length of the sunshine duration, and belongs to rare special animal fibers. Cashmere is so precious that it is not only due to its rare yield (only 0.2% of the total production of animal fibers in the world), but also its excellent quality and characteristics, and is considered as "fibrous gem" and "fibrous queen" in grams in trade.
