Cashmere is the raw material of cashmere, cashmere, the world's total output of 2% of all fiber fabrics in the world, 60% of these 2% produced in Inner Mongolia, China, that is, China is the world's largest cashmere producing areas. Cashmere sweater is characterized by: light, soft, warm and waxy, very suitable for personal wear, warmth retention, breathability, comfort are very good. Cashmere produced every year in the world, if all used for cashmere sweater, then every 5000 people in the world can share 1 pieces.
Woolen sweater raw material is sheep wool, wool unlined upper garment does not suit next wear, can have the feeling of tie person. The availability of JS to some good quality, fine wool labeled "Cashmere" to deceive consumers. Sheep are not cashmere, the so-called cashmere is only 105~115 degrees east longitude, 35~45 degrees north latitude between the Gao Hanrong goats produced. And the best wool is produced in Australia, the world's annual production of wool wool, if all made woolen sweater, then the whole world can have 2 pieces per person.
1., wool scale arrangement than cashmere tight and thick, and its cashmere cashmere than cashmere.
Curl curl is 2. smaller than the cashmere wool, cashmere fiber crimp number, crimp rate, crimp recovery rate is relatively large, suitable for processing for knitwear of comfortable, soft, good elasticity, wear comfortable and natural, and have good redox properties, especially after washing does not shrink, the type of good hand. Because of the high natural crimp of cashmere, it is arranged in spinning and weaving with good cohesion and good warmth retention, which is 1.5 times to 2 times of wool.
3. the content of cashmere is higher than that of wool, and the rigidity of cashmere fiber is better than that of wool. That is, cashmere is softer than wool.
4. the fineness of cashmere is smaller than that of wool, and the quality of its products is better than that of wool.
5. cashmere fiber fineness is uniform, its density is smaller than wool, cross section is regular circle, its product is thinner than wool products.
6. cashmere moisture absorption better than wool, can fully absorb dyes, not easy to fade. High moisture regain and relatively large resistance.
7., wool is superior to cashmere in acid and alkali resistance, and it is less damage than wool when it comes to oxidizing agent and reducing agent.
Usually 8. wool anti pilling of cashmere products than good, but felt great contraction.
Tip: market fake cashmere cashmere products mainly include: serious shortage, not enough to achieve the role of warm cashmere products; the second is shoddy, using fine wool instead of cashmere, cashmere fineness in general 13.5 microns to 15.5 microns, and the wool will be greater than the number according to the.
Two: how to identify cashmere and wool?
The high-grade cashmere products, 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 in order to reduce the cost, to deceive consumers, is unable to effectively identify the cashmere and wool for ordinary consumers, must rely on the detection of the institutions, only professionals with the microscope, through the identification of fiber surface morphology, it can be identified, so the market needs of textile testing organization identification and effective supervision of cashmere products. In the field of fiber inspection, the identification of cashmere fiber and wool produced by cashmere plants is the most recognized and most difficult testing item. A large number of fiber inspection workers have been working on the identification of cashmere fiber and wool for a long time. The same with wool cashmere fiber structure, similar chemical properties, it is because of wool and cashmere are "the same", which makes the method generally used ordinary burning method, the chemical solution method is difficult to classify and identify, at present the most effective is the microscope method. How do cashmere manufacturers rely on microscopic methods to identify fibers in order to obtain accurate results? Present is as follows:
A microscopic display of cashmere (left) and wool (right)
1. fiber analysts in the use of optical microscopy for cashmere and wool identification, you need to observe the two fiber scale structure and the overall shape to distinguish. Different from wool, the surface thickness of cashmere fiber is thinner than that of wool, and it is coated on the stem of wool, and the wool is thicker and inlaid. The density and coverage of the dry hair cashmere scales than wool, thus causing the cashmere fiber and wool different feel: cashmere fiber and wool relatively smooth feel, feel a rough. In 1983, Kush and Arns observed by scanning electron microscope (SEM): the thickness of wool end scales is larger than that of cashmere fiber, which is a great discovery. Prior to this, microscopic tests were based mainly on the difference between flake lengths. The difference between the wool and cashmere fibers under the microscope is on the right.
Later, Wortmann continues to scale thickness of 29 kinds of fiber were compared, including wool, cashmere, Iran cashmere, China cashmere, Mongolia cashmere and Ma Haimao of Afghanistan, alpaca wool, camel hair fiber. Finally, through the observation of a conclusion: if the scale thickness of a fiber is greater than 0.55 microns, should be recognized as wool; scale thickness and cashmere, special animal fibers should be less than 0.55 microns. The scale thickness of wool fiber should be larger than that of cashmere fiber, which provides strong proof for the workers who use fiber for fiber analysis.
2. because of the cashmere wool scales than thin, light under the microscope through good performance, light uniformity, fiber brightness uniformity, no shadow, no projections; and wool scale thick, uneven light, shadow and Maoganduo.
3., under the microscope, cashmere fiber scales covered with hair
