Donghua University: Let fiber “revamp”
Liberation Daily News (Reporter Xu Min) A PBO fiber with a diameter of 1 mm can actually lift a weight of 550 kilograms, and its strength is more than 10 times that of steel wire of the same specification; adding nanomaterials to traditional fibers makes chemical fiber clothing more comfortable to wear. It is as breathable and comfortable as pure cotton clothing, and has UV resistance… Yesterday, the International Academic Conference on Advanced Fibers and Polymer Materials was held at Donghua University. A series of new scientific research results presented by the school attracted the attention of experts attending the conference.
According to experts, my country produces more than 20 million tons of chemical fibers annually, but the proportion of high-tech fibers is less than 30%. There is much to be done in scientific research. The State Key Laboratory of Fiber Material Modification of Donghua University uses high-tech means to “reshape” fibers and produce various “special functions.” Its scientific research achievements have frequently won the National Science and Technology Progress Award in recent years.
Scientific researchers are doing “addition and subtraction” on traditional fibers to make people’s clothes more comfortable. By reducing the fineness of the fiber, changing the cross-sectional shape of the fiber, or adding ingredients with special functions inside the fiber, they have successfully developed varieties such as ultra-fine polypropylene, high moisture conductivity polyester, and functional series copolyester fibers. Fabrics made of these fibers are light, soft, smooth, moisture-absorbent, perspiration-wicking and breathable, which can significantly improve wearing comfort. The research team led by Professor Zhu Meifang added nanocomposite materials to the fibers, which significantly improved the performance of chemical fibers in aspects such as breathability, antistatic, antibacterial, and warmth retention. This technology has been industrialized, with an added output value of 1 billion yuan, and won the second prize of the 2006 National Science and Technology Progress Award.
A thin fiber can be weak and boneless, or it can be extremely rigid. High-strength polyethylene fiber can be used to make high-strength ropes, fabric bulletproof clothing, bulletproof helmets, etc. It has excellent properties such as lightweight, corrosion resistance, light resistance, and fatigue resistance. It has application prospects in aerospace, national defense, agriculture, ocean development and other fields. broad. At present, the annual output of this fiber is only 8,000 tons, making it a scarce material in the world. Since the 1980s, the “Industrialization of High-Strength and High-Module Polyethylene Fiber” research group at Donghua University has carried out relevant technical research simultaneously with international colleagues, overcome a series of technical problems, and developed PBO, which is known as the “super fiber” of the 21st century. Its strength is not only stronger than steel fiber, but also stronger than carbon fiber. As a result, our country has become the third country to master this technology after the Netherlands and the United States. At present, scientific researchers from Donghua University have overcome key technical problems in the industrial production of PBO fiber and achieved small-scale trial production.
