Wool is wool from sheep.
Cashmere is a thin layer of fine cashmere that grows on the outer surface of goats and is hidden in the roots of goat hair. It is a rare special animal fiber. Naturally adapted to the climate, naturally falling off.
In addition, cashmere sweaters are more expensive than wool sweaters because:
Scarce cashmere production
Due to the scarce production of cashmere, each goat only harvests tens of grams of cashmere, and an average of 5 cashmere can make a cashmere sweater. Therefore, the fabric is very luxurious and is called "soft gold", and each sheep can be cut each year. A few kilograms of wool.
Skin-friendly
Cashmere fibers are composed of scales and cortical layers, without medulla layers, which are very delicate. For wool, the edges of the scales are thick and not very clear, the sides have serrations protruding outwards, and the scales have a rough surface. Therefore, wearing a wool sweater alone can be a bit stingy, and cashmere can be worn directly. , Stimulate blood circulation and help reduce fatigue.
Different hygroscopicity
Cashmere is more hygroscopic than wool. Cashmere sweaters have the strongest water absorption among all textile fibers, with a moisture regain of more than 15%.
Different thermal performance
Under the same coverage area, the finer cashmere has a larger specific surface area, and there can be more static air trapped between the cashmere, so it has better heat retention. The cashmere is 8 times warmer than wool, and it is lighter than wool, and only weighs It is one-fifth, but it is also more delicate, and it is less durable than wool.
Some people also say that pure cashmere and pure wool are easy to pilling and feel bad.
In fact, 100% pure cashmere and pure wool are pilling. Because the cashmere sweater surface fluff formation mainly depends on the number of short fibers and the degree of shrinking. The more short fibers, the stronger the fleece, the more fluff, the softer the hand, the lower the firmness and wear resistance.
