The countries that produce commercial quantities of cashmere are China with 70% of the world’s output, Outer Mongolia at 15-20%, Iran and Afghanistan at a combined 10-15%. There are some small weights of cashmere produced in the Central Asian Countries of Kyrgyzstan, Tajikistan and Kazakhstan, in Turkey, India, Australia, New Zealand and Pakistan, but these quantities are small in comparison to the 3 primary producers listed above
The annual world output is estimated at app. 7,000 tons of raw cashmere. If you are familiar with wool or cotton production worldwide and the relatively high figures associated with each, you can start to understand why cashmere is so much more expensive than those natural fibers.
Cashmere comes from a goat. The combination of dietary and geographic conditions of the Central and East Asian steppe, mountain plateaus and deserts have evolved the goats that dwell there into the most productive cashmere fiber growers in the world.
Raw (greasy) cashmere is a mixture of fine underdown (which after processing becomes commercial grade cashmere) and coarse outer guard hairs, along with dirt, sand, animal grease, vegetable matter and other impurities. The greasy cashmere can either be shorn or combed from the goats. The greasy fiber is bought in the countryside by processors and traders, from where it is shipped to dehairing (processing) mills.
Once the stock arrives at a processing mill it is generally sorted with a number of goals in mind. The first is to sort out low-grade cashmere and any synthetic contamination that is found. The stock is then baled and stored. The second sorting comes when we are ready to break down the fiber into colors - White, Light Grey, Cream and Brown. During this second sorting we will again look for any lower grade fiber or synthetic contamination that got through the first sorting
After sorting, the greasy fiber is scoured (washed) to remove the dirt, grease and other impurities. After scouring, the washed cashmere is ready for dehairing. The dehairing machines remove the coarse guard hair from the soft underdown as the co-mingled mass of fiber passes through a series of dehairing heads on the machine.
The design of the machine allows for the underdown to remain in and pass through the machine while the coarse hair is removed. Once the scoured cashmere is passed through the dehairing machinery the residual coarse hair content is brought down to standard 0.5% for weaving grade fiber and 0.2% or lower for knitting grade fiber.
Actually, the residual coarse hair content can be as high as 3% and still be called commercial cashmere. However, at 3% the end uses of the fiber are limited. The ultimate goal of any dehairer is to economically remove most of the coarse hair and impurities while not damaging the length of the underdown.
The value of dehaired cashmere is influenced by several key factors: fineness (measured in microns), length (measured in mm), and color. China produces the finest and best white cashmere in the world. Consequently Chinese cashmere commands the highest price in the market place. Mongolian cashmere, while not heavily concentrated on pure white animals, is the next most desirable as it is only slightly coarser than Chinese and has superior length. Iranian and Afghan cashmere are normally the lowest price material on the market as they are coarser, darker and shorter in length than the other two types.
Once the fiber is dehaired it is ready to be shipped to spinners, weavers and knitters around the world. For many years the 4 traditional, primary markets for cashmere production had been the USA, Europe (UK and Italy), Japan and China itself. The finished products were consumed mostly in the first three markets mentioned, with China consuming smaller amounts of its own finished goods production.
The production of finished products, both in knits and wovens has dramatically shifted to China in the last decade. The consumption of cashmere finished product by the Chinese population has also increase dramatically in the past decade as China develops a consumer middle class.
