Carbon fiber Carbon fiber is a microcrystalline graphite material obtained by carbonization and graphitization of organic fibers. Its microstructure is similar to that of artificial graphite and is a layered graphite structure.
Carbon fibers can be processed into fabrics, felts, mats, belts, paper and other materials. In addition to the traditional use of carbon fiber in addition to thermal insulation material, generally not used alone, and more as a reinforcing material added to the resin, metal, ceramics, concrete and other materials, constitute a composite material. Carbon fiber-reinforced composites can be used as aircraft structural materials, electromagnetic shielding electrification materials, artificial ligaments and other body replacement materials as well as for the manufacture of rocket shells, motor boats, industrial robots, automotive leaf springs, and drive shafts.
At present, the world's carbon fiber production has reached 40,000 tons/year. China's carbon fiber is in the process of industrial production, but the quality and level of products are far from those of the United States, Japan, Russia and other countries.
The English name of protein fibrin fiber is protein regenerated fiber, which is a category of man-made fibers. It refers to proteins extracted from natural substances such as milk, soybeans, peanuts, and corn as raw materials, dissolved in suitable solvents, and with different base materials. - Fibers such as viscose and PVA obtained by grafting, copolymerization, etc.
Protein fibers are soft and comfortable to wear, making them ideal for the development of new fabrics.
Since the 1990s, foreign countries have begun to extract milk protein from milk to produce "a new generation of protein fibers" - casein fiber. China has also successfully developed its own.
Protein fiber is particularly suitable for the production of underwear, it is said that there is a certain "maintenance" effect on the skin, so it is favored by many businesses. In addition, self-developed soybean protein fiber in China has independent intellectual property rights.
Fibers with fine denier per filament of 0.5 to 0.1 dpf are called ultrafine fibers. The ultra-fine denier fiber is known for its delicate and soft hand-feeling.
Ultra-fine denier fibers are used for a wide range of applications, such as thick warm clothing, such as women's short coats, coats, etc.; in the field of high density fabric products, such as raincoats, outdoor sportswear, and jeanettes, microfibre remains unique. Advantage. Microfibers are commonly used as wefts in fabrics and are also widely used in jean and velvet fabrics.
The research on ultra-fine fibers in China began in the 1970s. At present, the industrialization of ultrafine deniers has been successfully achieved.
Compact Spinning Technology Compact Spinning Technology is a new type of device developed on ring spinning machines. It adds a negative pressure fiber condensing zone in front of the drafting device of the spinning machine, reducing the number of front rollers to the point of twisting. The spinning triangle area eliminates the negative effect of the triangular area on the surface structure of the yarn, significantly reduces the yarn hairiness, increases the strength and elasticity of the yarn, and improves spinning performance and environmental cleanliness.
At present, the international compact spinning technology has entered a mature application period. Some domestic textile machinery manufacturers and scientific research institutions are also optimistic about the application prospects of this technology and have invested in R&D and learning. They have developed compact textile technologies and equipment with independent intellectual property rights.
