Cashmere raw materials and their quality characteristics
I. Domestic cashmere raw materials and their quality characteristics (1) Classification of Cashmere Raw Materials Cashmere raw materials can be divided into two types of live cashmere and non-living cashmere according to the different production methods. 1, live cashmere Live cashmere includes live sheep fleece, live lamb shear and live sheep shearing. 1 Live sheep fleece, commonly known as “original velvet†and “live sheep scratchâ€, is the fluff that is removed from the body of the sheep when the goat naturally dehairs in late spring and early summer. Mostly in the shape of a lumps, with catching flowers; in the natural state, the velvet is round-headed, and the velvet is separated into bovine snakes; the surface hairs in the pile are twisted into filaments and woven into each other, commonly known as spiders. Hair"; feel smooth, color is positive, shiny, oily. In addition to the sheep's production areas, breeds, and color, sheep's fleece is divided into the main plush and two velvet. Head velvet - refers to the raw cashmere that is caught in time when the fluff is just beginning to separate from the skin on the side of the body. Its fiber is longer, the impurity content is lower and the quality is better. Two velvet - is from the cashmere ewes in the late gestation period when the ewes in the late pregnancy, lambs should not be early fleece, and frail and sick animals who passed the fleece season only to catch down the original cashmere. This type of fluff has a long time on the sheep, and the pollution is serious. The impurity rate is high, and the fluff is naturally detached or damaged. The fibers are short and contain a lot of thick and long medullary hair, and the quality is poor. The cashmere rate of live sheep fleece is generally around 50%. Because of the different techniques and finesse of fleece and the steel wire claws used for fleece, the raw cashmere contained coarse yarns and the impurity content is also different. Therefore, the cashmere rate and the impurity content of different raw cashmeres vary greatly.

This type of production is still used in individual areas, and the characteristics of cashmere produced are: short fiber length, half scattered state, and no clumps. Because some of the cashmere is left on the sheep, the production of cashmere is reduced. In some areas, due to various reasons, the fleece season was delayed and the cashmere fell off on its own to form a rust sheet, which was called "old velvet." This type of velvet is intertwined with each other, has poor oiliness, contains more coarse hair, darkness, low strength, and poor quality. 3 Goats live shearing, foot refers to cashmere goats once cut hair after fluff. Specifically, the number of days after fleece is used to cut the hair, and it should be determined according to the local warming conditions to prevent goats from freezing. Because this hair is cut off from the living sheep, it is also commonly known as "live sheep shear." Goat live shearing has a low velvet rate, typically 0.2%-2%; the fibers are also shorter. However, since the villi are not contaminated by chemical drugs, their elasticity and strength can be maintained well, and the villi hair has a higher quality of depilation. 2, non-live cashmere Non-live cashmere includes leather shears, leather nap, skin fleece, and leftovers.

However, the scraps and scraps are generally treated with chemical drugs. The color and strength of the velvet are less than that of live shearing. 2 skin nap, including: dry velvet, ash, melamine, medicine, and water fading. These four types of velvet are tanneries that use lime, hot water or chemical drugs to fade from the skin. Dry embossed refers to the use of sodium sulfide and hydrated lime to remove fluff from goatskin and remove the coarse hair. Its characteristics are: It is in sheet form, with velvet, dark and shiny, oil-free, poor resistance. Grey linting—refers to the velvet that fades when soaking goatskin with lime during tanning. Its characteristics are: most of the plush mixed into a block, short fibers, poor pull, velvet, shiny dry, oil-free. The soup is puddled - the fluff which pulls down the fluff from the hot water. Its characteristics are: fiber adhesion winding, poor luster, hair astringent, velvet, flaky. Moisture - is a kind of drug-fainting, that is, when the fluff is exfoliated, the skin is first covered with chemical drugs, and immediately the water is used to wash away the drug. Its purpose is to protect the hairy peaks of hairs and reduce the damage of chemical drugs to facilitate the production of pens. Therefore, the water wadding is better than the velvet quality of the medicine. 3 leather fleece, including rawhide fleece and mature skin fleece. Hide fleece refers to the velvet that is caught from goatskin. Its characteristics are: short fiber, containing less coarse hair, catching flowers clearly, catching eye round, dark luster, poor oil. Cooked leather fleece refers to the fleece that is grasped from cooked goatskin. Its characteristics are: short and hairy astringent, clean, catch the flowers clearly, scratching the eye round, with nitro or slightly acid, non-oily.

The number of waste pencils in the pen line is small, because it has already removed the long hair needles, so the cashmere rate is higher and can reach more than 70%. The raw materials are generally derived from water dehairing and live sheep shearing. Fluff waste refers to raw materials that can be reprocessed in the waste generated during fluff processing. It mainly comes from the short velvet contained in the soil lost from the bottom of the opener and the gruff waste (commonly known as "gross") still containing a small amount of short velvet collected in the bottom of the velvet machine. Its wool content is extremely low and its fiber length is short. (2) Cashmere raw materials still used in small amounts for cashmere processing of cashmere 1, floe. Commonly referred to as "velvet cover", refers to the flannel of the fluffed clothes. Due to the varying length of time, the quality varies greatly. Its characteristics are: fleece is flaky, dark or dull gloss, sweaty, with thread, poor oil or no oil. 2, oily. Features Adhesive fluffy hair, hard hair, dull, dull, oily. The formation of fluff is mainly due to the following reasons: When fleece is produced, it is caused by the application of vegetable oil on the claws of the wire; when the goat has a skin disease, various oily ointments and syrups are applied to the goat to treat the disease, contaminating the body of the sheep. Forming fleece. 3, cashmere velvet. Fleece cut from the affected area of ​​a sheep suffering from dermatophytosis. It is characterized by mixed with exfoliated resin-like secretions, dander, villi, and sometimes a hard mass. Goat ticks are caused by fungus and other ectoparasites such as cockroaches, cockroaches, and fleas on the skin of goats. At present, administering a medicinal bath to goats can eliminate the ectoparasites of goats, especially ticks. In addition to lump velvet block and fiber adhesion, the gloss and strength of cashmere are also affected. After lightly chopped cashmere has been washed, the wool in the adhesive state can be loosened, but the severed bristle pieces cannot be removed, causing difficulty in processing such as carding.

Classification and Quality Characteristics of Imported Foreign Cashmere The countries that produce cashmere in the world mainly include China, Iran, Mongolia, Afghanistan, Turkey, and the former Soviet Union. Cashmere imported into China from abroad can be roughly divided into three categories. 1. The goat wool imported by Mongolia and the former Soviet Union is commonly referred to as "coarse and fine detail." It contains a high amount of cashmere, but the hair is thicker. 2. Cashmere goats in Iran and Afghanistan, commonly known as "Ginsihair." Its species and quality are similar to cashmere in southern China's Xinjiang and Tibet, with little difference. 3. The angora goat hair produced in Ankara, Turkey, is commonly known as “mohairâ€. The hair is slender, strong and shiny, but the hair is thick.
