.f15 {FONT-SIZE: 14px; LINE-HEIGHT: 150%} A seemingly ordinary fiber rope, the maximum weight it can withstand is 8 times the same weight wire rope. Recently, the reporter learned from the Chemical Fiber Institute of Donghua University that the institute, in cooperation with China Textile Investment Corporation, mass-produced the world's most powerful fiber, high-strength and high-modulus polyethylene fibers, and broke the monopoly of the United States and the Netherlands over the long term. At present, the chemical fiber research group has launched two new projects of high-strength fibers. According to reports, the strength of high strength and high modulus polyethylene fiber is extremely high, if you use a stainless steel scissors to cut it, cut in a row after a continuous cut will passivation. The fiber can be used to make high-strength rope, fabric bullet-proof vests, bullet-proof helmets and other products in the aerospace, defense industry, agriculture, marine development and other fields with broad prospects. At the same time, the fiber has the advantages of light weight, corrosion resistance, light resistance, fatigue resistance and the like. The weight of the bulletproof protective clothing made by the bulletproof clothing is lighter and bullet-proof than the traditional bullet-proof clothes. Since 2002, China has invested the high-strength and high-modulus polyethylene fibers produced and invested by China Textile into the recovery system of the Shenzhou spacecraft, contributing to the development of the aerospace industry. According to Professor Liu Zhaofeng, the first person who completed the project of "Industrialization of High-strength and High-modulus Polyethylene Fiber", the global annual output of this kind of fiber is only 8,000 tons, which is a scarce commodity in the world. China's annual output of up to 1,000 tons, annual export revenue of more than 200 million yuan, all of its core technology from the Institute of Chemical Fiber Donghua University's achievements from. It is reported that the task force staff lasted more than 20 years, and gradually overcome from spinning to stretching a series of technical problems, and all the domestic market can purchase domestic raw materials, to achieve national product. The project won the first prize of scientific and technological progress in Shanghai, and applied for 9 patents, has authorized 6 items. It is reported that Donghua University Chemical Fiber recently aiming at high-strength aramid and PBO fiber. Both fibers are extremely heat resistant and currently only the United States and Japan are able to produce them. This project will enter the pilot phase this month.
