Cashmere is a layer of fine wool from cashmere goats (also known as cashmere goats), with a diameter of 14- 17um and a length of 30-45 mm Cashmere fiber is composed of cortex and scales, and its cross section is oval-cylindrical. One cashmere goat can only produce about 75 grams of cashmere a year, and five cashmere goats can only produce enough cashmere to weave an ordinary cashmere sweater a year.
? The appearance has natural luster, softness, richness, softness, lightness, warmth, smoothness, elasticity and good luster, and it is known as the "king of fibers".
? Cashmere fiber is short in length and low in strength, and the scales covered on the fiber surface are thin and close to each other. Because the crimp number and friction coefficient of fiber are less than wool, the fiber is smoother, the cohesion between fibers is poor, and the felting shrinkage is worse than wool, but it feels smooth and waxy. Although the crimp of cashmere fiber is small, the crimp depth is large. Generally, the straightness of cashmere is over 300%, while the wool of 64 Merino sheep is only 160%, so the warmth retention of cashmere products is better than that of wool.
Under the same temperature and humidity conditions, cashmere absorbs moisture more easily than wool. Cashmere fibers can be soaked in water in a few seconds, while wool takes several minutes. Because the output of cashmere in the world is only 1% of that of wool, the price of cashmere is more than ten times that of wool, and it is the most precious animal fiber. Because cashmere fibers are thinner than wool, cashmere fabrics are easy to pilling when worn, and the cohesion between fibers is poor; Compared with wool, cashmere yarn has low strength and poor fastness, so contact with hard objects should be avoided when wearing it. Cashmere fiber absorbs moisture easily and is easily eaten by insects. When you put it away, you should wash it and fold it, and put it in a suitcase with moth-proofing agent or a plastic bag with several holes.
? The correct identification method is generally just softer and smoother. Consumers complain that the so-called "coat" worth thousands of dollars is suspected to have quality problems. This can only be done through physical and chemical tests. After sampling, observe the film on the projector to see if there is cashmere. The "sheep hair" on the market has nothing to do with cashmere. "Sheep wool" is actually wool. The fineness of wool is 20-40mm and the length is 50-200mm, but it is a little thinner than ordinary wool. Sheep only produce wool, not cashmere. The so-called "wool quilt" products should be treated as "fake and genuine". It is cashmere that smells when burned, and the ashes can be twisted into powder.
