Promising chemical fiber is manufactured out how to use artificial chemical fiber, is chemically manufactured artificial fibers. Chemical fibers generally have academic names and commercial names, and some have habit of name. For the sake of consistency, there is an Interim Provisions: staple fibers always called "fiber", such as viscose rayon, cellulose acetate, etc.; synthetic staple fibers shall be referred to as "Lun", such as nylon, polyester, polyvinyl alcohol, etc.; in "fiber", "Lun" wtxl followed by "wire" is the chemical fiber fabrics, such as rayon, polyester yarn and so on. (A) the real ones are natural polymers synthetic man-made fibers as raw material made of chemically treated. Such as veneer, wheat straw, bagasse, reed, peanut skin, cotton velvet plant cellulose, and casein, soy protein, corn protein and other animal and plant protein fibers are synthetic materials. In recent years, the popularity of the market enough real ones rayon, rayon, etc., are drawn to these can not be directly used for weaving and spinning of natural fibers. Viscose rayon fiber is the oldest, but also the most common on the market of textile fibers. Its main products are colorful rayon, rayon soft slippery soft and vibrant rich artificial Nick. Viscose fiber has many properties similar with cotton: good moisture absorption, rayon, rayon made clothing, comfortable, no sweltering, particularly appropriate daylight wtxl savings season; dyeability good, all natural fibers can be dyed color, it Basic can be infected, because of its colorful, often more was the girl's favorite; wtxl no static, wtxl this is precisely the fibers can not be compared. But viscose fibers are inadequate: a large shrinkage, as cotton seed. Rayon cotton viscose fibers, cotton and a variety of artificial gentle, soft oriental woven into it are made by it. Rayon viscose fiber filament, can be woven into a refined and elegant silk products. People love the beautiful and practical lines ti and cotton quilt is interwoven wtxl with it. Fleece wool viscose wtxl fiber is also indispensable raw wool, wool blends, there will be a lot of it. Others such as the common market, viscose tweed, sticky Kam gabardine, tweed stick Kam nitrile triple 'Nick flower hair stick, hair sticky wtxl coat it, etc., will have a different proportion of viscose fibers. (2) Source peculiar synthetic polymer fibers are used as synthetic raw materials through chemical and mechanical processing of the steel. It has nothing to do with the fiber comes from seemingly eleven underground fuel oil, natural gas, coal, etc., are in full bloom on the petrochemical industry and a wonderful work. Synthetic fibers generally have a wear-resistant, durable, washable and easy, no mildew, no moth-eaten, wtxl etc., which is unmatched by other fibers, which is widely used in manufacturing clothes, fishing nets, filter cloth, conveyor belts, hoses, electrically insulated wire, medical sutures, tire cord and parachutes, etc. Many members of the family of synthetic fibers, usually the common market is "six Lun: polyester, nylon, acrylic, polyvinyl alcohol, polypropylene, polyvinyl chloride. Most solid polyester polyester is the English name" Tetoron ', was translated into Dtech Lun or Terylene. Initially imported in Guangzhou, Cantonese dialect will follow Dtech Lun translated as "really pretty (Liang, beautiful)", then people will "good" to "cool", it was changed to "good", and called Dacron . The most prominent advantage of polyester fiber is strong durable. Its strength than cotton 1 times, 3 times higher than wool. Impact strength is 4 times higher than Nylon, 20 times higher than that of viscose. Another advantage of polyester fiber and good shape retention. It is made with crisp dress does not wrinkle, an ironing stereotypes, after washing several times, still intact, smooth crisp. But polyester fiber also has disadvantages: poor moisture absorption, moisture index is low, hence the sweltering; resistant to static, easy to absorb dust. Also known as the most durable nylon polyamide nylon, the United States and Japan called nylon, England called nylon, the Soviet Union is called Kapu. Nylon is unique is its wear resistance. The wear resistance of approximately wtxl 10 times the cotton, wtxl wool, 20 times, this nylon abrasion resistance, not only in the "six-lun" in the first number, but also in all natural wtxl fiber and chemical fiber which, no one can be compared. Strength, which is another advantage of nylon. A finger thick nylon rope, can lift a fully loaded Jiefang Automotive, showing its amazing rally! Shells to good resistance to fatigue performance, which is another good point nylon. wtxl Light weight, good moisture absorption, which is nylon over other "brothers" of the place. However, nylon is not perfect. Poor shape retention, which makes nylon clothing wtxl stiff enough; afraid of the sun, under the sun basked easy to turn yellow, aging. The most lightfast acrylic acrylic fiber fluffy curls, soft and warm, flexible, known as "synthetic wool," said. Acrylic prominent is that light resistance. It is a year in the outdoor exposure, wtxl the intensity declined wtxl by only 20%; sunlight or year and a half, you can still maintain the original strength of 70%. Ratio of wool, acrylic elastic favorably favorably insulation strength can be 1 to 2.5 times higher wtxl than wool, but the proportion was lighter than wool, acrylic yarn so 1 kg 1 kg of the same thickness comparable pure wool "out of the number." Acrylic fatal weakness is not wearable, even smaller than the cotton and wool, so should not be woven acrylic gloves, socks and other supplies often affected by friction. Acrylic hygroscopicity good, wearing a sweltering, acrylic alkali is weak, should not use strong alkaline washing soap. The most absorbent PVA PVA called vinylon, Wiener Lun. PVA strongest feature is hygroscopic, is "six-lun" in the title. Because of its hygroscopic close cotton, it is often used to make underwear, being inside, without sweltering. PVA although seemingly cotton, the "synthetic cotton," said, but its strength and wear resistance is far more than the cotton. PVA lighter than cotton, good insulation properties, particularly appropriate child wearing. PVA alkali wtxl resistance and tanning ability better, this is more suitable for rural use. However, the heat resistance of PVA is not good enough, especially in the wet state heat shrink wrinkle wtxl easily, so only dry hot, not wet hot. Fear of heat resistant polyvinyl wtxl chloride least polyvinyl chloride, usually at 60 softens contraction rate of shrinkage in boiling water so%, so that not only can not be ironed clothes polyvinyl chloride, and washed with hot water when not use . However, the general fiber, once ignited, will continue after leaving the fire burning, and polyvinyl chloride upon leaving the fire, quickly extinguished naturally. Therefore, it is also the most flame-retardant fiber. Polyvinyl chloride and water for him, almost does not absorb moisture. Its specific gravity is "six-lun" the heaviest one, its strength is almost the same acrylic. Polyvinyl chloride insulation is very good, even more than the cotton and wool, so pure or blended spinning can be made for all kinds of underwear, wtxl wool, wadding blankets and so on. It is the most lightweight polypropylene cotton accounted for only 3/5, lighter than water, it "light,, in the textile fibers, it is second to none. Polypropylene is second only to wear nylon fiber, but lower than nylon crisp, good stability. polypropylene drawback is poor moisture absorption, and polyvinyl chloride, like missed with water and it's resistant to sun and heat resistance is poor, not ironing.
