Donghua University Studies Aramid 1313 Fiber Debut At Expo

　　 Aramid fiber 1313 The development and application of the technology has broken the technical blockade of the United States for 40 years. Maybe you can not imagine that a yellow sheet of paper that is not amazing can withstand high temperatures above 200 degrees. It is used as insulation material for large motors and spanformer coils. This kind of paper is known as "the darling of high-performance fiber family". meta-aramid (also called Aramid 1313), it is not only light and thin, but also has high heat resistance and flame resistance. It has good textile processability and insulation performance. Firefighters wear clothes made of this material, and do not have to fear heat and fire any more. Workers wearing high voltage near the high voltage wear arc protective clothing made of this material to solve the long-term safety problems perplexing operators in the power industry. This material can also be widely used as a high-temperature filter material to clean the exhaust gas discharged from power plants and cement plants without being melted, so as to keep the air fresh and natural. The "honeycomb material" made of it can also be used as a "secondary force" of a fast train or airplane. Recently, from Donghua University Professor Hu Zuming led the team to develop the key technology of "aramid fiber and insulation materials industrialization". Shanghai Industrial Expo 。 The development of the technology has broken the technical blockade of the United States for 40 years. At present, the establishment of an aramid and insulation paper industrialization system with independent intellectual property rights has been established, and 6 national invention patents have been applied. 3 authorized items have effectively promoted the scientific and technological progress of the textile and chemical fiber industry. In the past three years, the total output value has reached 854 million yuan, 222 million yuan in profits and taxes, and 72 million 240 thousand yuan in foreign exchange earnings.

High moisture polyester fiber changes your life:

As the saying goes, "eat, wear and live", "wear" ranks the second in Chinese traditional culture. With the improvement of people's living standard, the quality of life has attracted more and more attention. Contemporary people not only pay attention to dress beautifully, but also want to dress comfortably. What kind of fabric can absorb moisture and comfort like cotton, and has the characteristics of fast drying, non crepe and non close fitting? It can be beautiful and keep the skin dry and comfortable. Recently, at the Shanghai Industry Fair, the key technology of highly conductive polyester fiber and products developed by Professor Wang Huaping of the School of materials, Donghua University, can achieve this effect, so that your life can enjoy a warm and comfortable feeling like early summer. According to the introduction, at present, through the combination of production, study and research and brand operation, the high moisture conductive polyester fiber has realized the systematic and large-scale production of fabrics and clothing. The "Cooldry" wet dry fast drying products developed by them have become famous brands both at home and abroad. They have been registered in China, Japan, the United States, Europe and other countries. The products are widely used in famous brands such as Reebok, Kappa, Hummel, Lining, Anta, JEANSWEST and other famous brands at home and abroad, and become the designated uniforms for important events such as the world cup and Olympic Games. They are exported to more than 10 countries such as Japan, the United States, Europe, Australia and so on. From January 2004 to December 2009, the newly increased production value was 824 million yuan, new profits and taxes of 265 million yuan, and foreign exchange earning more than 69 million 80 thousand dollars, which effectively promoted the core competitiveness and technological level of China's leisure sports textile fabric industry. It is understood that sportswear and sportswear made by CoolDry not only sweats like cotton, but also dries quickly, which is 25% lighter than that of ordinary polyester, and is easier and more comfortable to wear. Due to the use of special section structure and special finishing method, it can quickly release moisture from the skin, and let the outer layer of cool air penetrate into the inner layer. Many fabrics, such as silk and so on, are comfortable and light, but difficult to care. CoolDry solves this problem. Because of its good shape retention, it is very convenient to care and can be washed and dried by machine, and it is not easy to deform. At present, Donghua University has developed hundreds of fabrics with the cooperation of production enterprises, and has established a scientific and perfect special testing and evaluation system for high moisture permeability fabrics. It has formed a set of integrated technologies suitable for developing high moisture conductive polyester spinneret design and processing, fiber production and fabric structure design and addition, and product performance evaluation. The overall technical index of fiber preparation technology and fabric has reached the international advanced level.

Digital tufting carpet

Digitized tufted carpet looms make the carpet look bright. The new machine developed by Donghua University has solved a series of technical innovations to solve the key problems of the tufted carpet loom such as the weaving range, weaving accuracy, weaving efficiency, power consumption of the whole machine, and the rate of finished product. The carpet surface has no striations, and it also solves the problem of blurring of the floral shape and low resolution, and realizes the precise weaving of the pattern resolution of 1 stitches. So that the public can use high-end carpet with complex flower patterns and relief patterns.
