Many people think that cashmere is fine wool, but not the same, cashmere is different from wool. Cashmere is grown on goats and wool is grown on sheep. A: The difference between cashmere and wool 1. Wool scales arranged closer and thicker than cashmere, the cashmere than its large cashmere. 2. The curl of wool is less than the curl of cashmere, the number of curls of cashmere fiber, the curling rate and the curling recovery rate are both large, so it is suitable to be processed into full-knit, soft and elastic knitwear, comfortable and natural to wear, and Good reduction characteristics, especially after washing does not shrink, good shape retention and so on. Due to the high natural curl of cashmere, arranged closely in the weaving of spinning, good cohesion, so warm and good, 1.5 times to 2 times the wool. 3. Cashmere cortex content higher than wool, cashmere fiber rigidity is better than wool, that cashmere softer than wool. 4 cashmere fineness of the unevenness than the small wool, the appearance of the quality of their products better than wool. 5. Cashmere fiber fineness uniform, its density is smaller than the wool, the cross-section of the rules for the round, the products lighter than the wool products. 6. Cashmere hygroscopic than wool, can fully absorb the dye, not easy to fade. Residues high, the resistance is relatively large. 7. Wool acid, alkali resistance than cashmere good, case of oxidants and reducing agents also less damage than cashmere. 8. Usually anti-pilling wool products than cashmere products, but felt shrinkage. Tip: fake cashmere products on the market mainly include: a serious shortage of cashmere, not enough to achieve the effect of cashmere products warm; followed by shoddy, the use of fine wool instead of cashmere, cashmere fineness of 13.5 microns in general .5 microns, while the wool is greater than this data. Second: How to identify cashmere and wool Cashmere products, high-grade, and with the popularity of cashmere products, some manufacturers in order to obtain high profits in the production of cashmere products, the incorporation of wool fiber to reduce costs and deceive consumers, for Ordinary consumers are unable to effectively identify cashmere fibers and wool must rely on the appropriate testing agencies, only professionals with the help of the microscope, through the identification of fiber surface morphology, can be identified, so the market needs of textile testing agencies Cashmere products for effective identification and supervision. In the field of fiber testing, the identification of cashmere fiber and wool is recognized as the most technically difficult test items. A large number of fiber testing workers have long been engaged in cashmere fiber and wool identification technology research. The same structure and the same chemical nature of cashmere fiber and wool, precisely because of the "same" of wool and cashmere fiber, it is very difficult to distinguish and distinguish by common methods such as combustion method and chemical dissolution method. At present, the most effective method Is a microscope method. How to rely on microscopy to identify fibers for accurate results? Are described below: 1. Fiber analysis workers in the use of optical microscopy for cashmere and wool identification, the need to observe the structure of the two kinds of fiber scales and the overall shape to be distinguished. The difference is that with the wool, cashmere fiber surface thickness than wool thin, mostly ring-shaped coating on the hair shaft, while the thick wool was inlaid. And the density of cashmere covered by the scales is smaller than that of the wool, resulting in the different handfeel of the cashmere fiber and the wool: the cashmere fiber has a smooth hand feeling and the relatively hand feeling of the wool is relatively rough. In 1983, Kush and Arns observed with a scanning electron microscope (SEM) that the edge thickness of the wool tip was significantly larger than that of the cashmere fibers, a significant finding. Prior to this, the microscopic examination was mainly based on the difference between scale lengths. Wortmann Wortmann continued to compare the thickness of the scales of 29 different fibers, including wool, Chinese cashmere, Iranian cashmere, Afghan cashmere, Mongolian cashmere and mohair, Alhur Paka hair, camel hair and other fibers. Finally, we conclude by observing that if a fiber has a flake thickness of more than 0.55 μm, it should be considered as wool, while the scale thickness of a special animal fiber including cashmere should be less than 0.55 μm. Wool fiber flake thickness should be greater than the cashmere fiber, which provides a strong proof of the use of microscopy for fiber analysis workers. 2. As the cashmere scales than wool thin, light transmission through the microscope under a good, uniform light, uniform fiber brightness, no shadow, no protrusions; and wool scales thick, uneven light transmission, hair dry and more Shadow sense and protrusion. 3. Under the microscope, cashmere fiber scales coated hair shaft tightly, Qiaojiao very small, relatively smooth and paste; and wool due to thicker scales lead to Qiaojiao, surface protrusions more, the lack of a sense of smoothness. 4. Cashmere scales longer, spaced, arranged less than the density of wool, the coefficient of friction between the scales is small, so after washing down wool than good; and wool is poor. 5. Cashmere fiber hair dry uniform, little twist, deformation; and wool fiber uneven hair, twist more. 6. Due to the uneven distribution of cortex on both sides of cashmere, curl than wool curl. Three: How to distinguish between cashmere sweater, sweater and cashmere sweater Cashmere sweater is woven into cashmere products. Because cashmere fibers are shorter than fine wool and thinner than fine wool, they are usually spun into 80-120 fine yarn, so the fabric is particularly soft, has good warmth and elasticity, and is particularly comfortable to wear. After adding a small amount of nylon, cashmere sweater more wear-resistant. Cardigan is knitted with knitted wool products. Knitted velor wool and pure acrylic and other varieties, is composed of two single yarn together. Raw materials for fine wool, wool into a thin and soft velvet, the quality is better, and the cashmere sweater is difficult to distinguish, or even mistaken for cashmere sweater. Fleece is made of fine wool and coarse wool knit wool knit. Fine wool yarn used in the smaller, coarse wool wool fiber slightly thicker. Regardless of fine wool or coarse wool yarn, the raw materials are generally sheep wool products. In addition, there are pure acrylic or wool blended velvet woven shirt clothing, but also has a sense of hair, bright and beautiful.
