In this cold winter, when it comes to keeping warm, people must think of cashmere products. In fact, people often confuse cashmere with wool, mistaking it for one, but it is not. With different warmth retention, under the same coverage area, fine cashmere has a large specific surface area, and more static air can be trapped between cashmere, so it has better warmth retention. Cashmere is 8 times as warm as wool, and is lighter than wool, accounting for only one fifth of its weight. It is the best choice for winter clothing fabrics, but it is also more delicate, and its durability is lower than wool.
Different sources
Cashmere from goats is called cashmere, that is, cashmere. Cashmere is a thin layer of fine wool that grows in the outer skin layer of goats and covers the root of the coarse hair of goats. It grows in cold winter to resist the wind chill, falls off when it gets warm in spring, and naturally adapts to the climate. It is a rare special animal fiber, called soft gold.
What comes from sheep is called wool. Even though the wool is very fine, it is also called wool in the industry and profession. Wool products have the characteristics of fullness, warmth retention and comfort. The best wool in the world comes from Australia. Australian Merino wool is usually considered the best wool. Its fibers are curly, light, soft and elastic. It is suitable for making fine worsted fabrics. Since it is not advertised, it seems not quite right. I would like to share some knitwear with Qi fans, all of which are made of Australian Meileno wool.
Acquisition mode
Different wool collections are like haircuts or undressing. All wool is shaved with scissors, and the whole wool is "taken off". It's called shearing wool. Cashmere grows at the root of coarse goat hair. When it is depilated in spring, herdsmen will use special iron combs to pluck it like a comb, and it will become raw wool.
Different yields
Each sheep can produce several kilograms of wool every year, and each goat can only harvest dozens of grams of cashmere every year. In 2017, the global wool output was about 1.1 million tons, while cashmere was about 20000 tons. It can be said that cashmere has become a "luxury".
