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.

Application range of aramid fiber

Para-aramid has good ballistic properties and is specifically available in soft and hard structures in defense security protection. Para-aramid textile can be made into bullet-proof vest, explosion-proof blanket, or composite type with epoxy resin into hard hat, armor explosion-proof inner gasket. Para-aramid also has good laser cutting resistance, temperature resistance and abrasion resistance, and can be used as safety protective clothing in industrial production. Cotton gloves made of para-aramid can avoid damage to fingertips from laser cutting, abrasion, puncture techniques, continuous high temperature and fire in industrial production processes.

Consolidate the industrial foundation of Jiangsu high-performance fiber materials high-quality development

High-performance fibers and their composite materials are key strategic materials, and their excellent comprehensive performance has been applied in the fields of aviation, aerospace, wind power generation, rail transportation, and automobiles. For example, in the automotive field, brake pads prepared by high-performance fiber materials can reduce brake braking noise, enhance wear resistance, shorten brake distance, extend service life and reduce the number of replacements.

Where is the road to the development of China's fiber materials industry?

In 2019, China's chemical fiber production was about 5.95×107t, accounting for about 80% of the total global chemical fiber production, which is the pillar industry of the national economy. Nowadays, in the context of international textile industry redistribution of labor, China's chemical fiber industry development faces some outstanding problems, such as the quality and cost of high-performance fibers do not have a competitive advantage in the market; bio-based fiber products are produced on a small scale, high cost, and can not yet effectively replace petroleum-based fiber products. These problems restrict the sustainable development of China's chemical fiber industry, affecting the formation of the industry's international competitive advantage. But these problems are also constantly prompting us, China's fiber materials industry urgently needs to accelerate the development of advanced fiber materials, so as to drive the chemical fiber industry and the textile industry's high-quality development!

Introduction to Aramid

Aramid fiber, known as aromatic polyamide fiber, is obtained from the synthesis of aromatic diamines and aromatic dibasic acids. According to the position of the amide bond and aromatic ring linkage, can be divided into inter-aramid (also known as aramid 1313) and para-aramid (also known as aramid 1414). Para-aramid has high specific strength, high specific modulus, high temperature resistance and flame retardant and other excellent properties, and carbon fiber, ultra-high molecular weight polyethylene fiber and known as the world's three high-performance fibers.

Aramid development prospects

Since the beginning of the 21st century, China has included para-aramids and fibers as one of the key new materials for development in China, and the State Council, the National Development and Reform Commission and the Ministry of Industry and Information Technology have repeatedly included para-aramids in the list of key new materials for development.

China's aramid development status

China has started the research of meso-aramid technology since 1960s, but it has not reached the industrialization technology level because of the low level of overall chemical industry. Until 2004, Taihe New Material took the lead in industrializing meso-aramid in China, breaking the monopoly of foreign countries, and now the domestic meso-aramid has a certain scale, with a production capacity of about 12,000 tons/year, of which Yantai Taihe has a production capacity of 7,000 tons/year, second only to DuPont of the United States.

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

High-performance fiber refers to the external physical and chemical effects of a class of special fibers with special tolerance, is one of the main development direction 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 fibers are not only an important strategic material urgently needed for the development of aerospace and defense industry
