Background needs and strategic significance of the development of high-performance fiber industry


High-performance fiber refers to a class of special fibers with special tolerance to external physical and chemical effects, is one of the main development directions of the chemical fiber industry in recent years, according to the chemical composition can be divided into organic high-performance fibers and inorganic high-performance fibers. High-performance fiber is not only the development of aerospace and defense industry urgently needed important strategic materials, but also in the promotion of various strategic emerging industries and low-carbon economy, energy saving and emission reduction plays an irreplaceable role, is a reflection of a country's comprehensive strength and one of the signs of technological innovation. Since 2006, with the key support of national policy and finance, China's high-performance fiber industry has developed rapidly, establishing a more complete domestic high-performance fiber preparation technology research and development, engineering practice and industrial system, significantly reducing the gap with developed countries, effectively alleviating the The national economy and national defense construction of the urgent need for high-performance fibers.

Some factors affecting the tensile breaking strength of aramid yarns

The compressive strength of aramid yarn is high, which means that it has a very good tensile strength and is therefore commonly used in fire safety, electrical engineering construction, railway lines, petrochemical equipment and other industries. As a fiber ductile yarn, the performance of aramid yarn can take into account the requirements of various natural environments, especially in the field of cable wire to give full play to the significant advantages. Aramid wire is commonly used because it depends on its good tensile strength, then what are the elements that endanger the fracture strength of aramid wire Rashen, we simply grasp the next.
