Yarn count is a unit of measurement that indicates the thickness of the yarn. Generally, the higher the yarn count in China, the thinner the yarn. For example, 10 count yarns are much thicker than 40 count yarns. The higher the count, the finer the yarn.Like other fabrics, cotton fabrics are distinguished by their fiber quality, that is, by the count of their cotton fibers. Fabric count refers to the number of yarns in a square inch of fabric. Therefore, it is also called Yingzhi, or S for short.The count is a measure of the thickness of the yarn. The higher the count, the softer and stronger the fabric, and the thinner the fabric, the better the quality of the fabric. Combed cotton generally has 21, 32, 40, 50, and 60 cotton. The higher the count, the denser the cotton cloth, the softer and firmer it is.
1. Basic principles
Cashmere is a layer cashmere yarn of fine fluff from cashmere goats (also known as cashmere goats). The diameter of the fluff is 14-17um and the length is 30-45mm. The cashmere fiber is composed of a cortex layer and a scale layer. The annual production of cashmere goats is only about 75g without cashmere, and the cashmere produced by five cashmere goats in a year is only enough to weave an ordinary cashmere sweater.
2. From the appearance of cashmere
It has natural luster, soft and plump, soft, light, warm, slippery, elastic, good luster, and is known as "the king of fibers".
3. Cashmere fiber
The length is short, the strength is low, the scales covered by the fiber surface are thin and thin, and they are close to each other. Because the fiber has less curl than wool, and the friction coefficient is smaller than wool, the fiber is smoother, the cohesion between fibers is poor, and the shrinkage is worse than wool, but the feel is slippery.
Although the cashmere fiber has less curl, the curl depth is larger. Generally, the straightness of cashmere is more than 300%, while the 64 merino wool is only 160%. Therefore, the warmth of cashmere products is better than wool.
Under the same temperature and humidity conditions, cashmere is more hygroscopic than wool. Cashmere fibers can soak in a few seconds in water, but wool takes a few minutes. Since the world's cashmere production is only 1% of wool production, the price of cashmere is more than ten times that of wool, which is the most precious animal fiber.
Because cashmere fibers are thinner than wool, cashmere fabrics tend to pilling when worn and have poor cohesion between fibers; cashmere yarns have low strength and poorer fastness than wool, and should avoid contact with hard objects when wearing; cashmere fibers are easy to absorb moisture Insect moths should be washed and folded when stored, and placed in a suitcase with an anti-moth agent or a plastic bag with several holes.
