The source is different.
Cashmere and wool derive from different types of sheep: wool derives from sheep, while cashmere is from goats.
Collecting wool likes a haircut, shaving all the wool with a scissor is OK, and each sheep can produce a few kilograms of wool per year.
The cashmere grows at the root of goat husk, cashmere collection needs a special comb to comb them down, and one goat can only generate dozens of grams of cashmere.
Though fine and soft as wool is, it can not be called cashmere.
The difference between them can be clearly seen using a microscope: the diameter of cashmere is of 14 to 16 microns, more thinner than wool;
the chaff scale of wool is pointed, while it is round for cashmere; and cashmere has no medulla.
Cashmere is 1.5 to 2 times warmer than wool, and feels more silky. Slight fold will be able to resume leveling as long as hanging one night, and the cashmere products will not shrink after washing.
In addition, wool mainly comes from the southern hemisphere, such as Australia, while cashmere mainly comes from the northern hemisphere, China's production accounts for about 50% to 60% of the world with best quality. Cashmere can only be harvested in the early spring, and the production accounts for only 0.2% of the world's animal fiber production, so it is expensive.
