China's high-tech fabric "gold wire" will be civilian

The "polyimide fiber" known internationally as "golden silk" has recently been used in the field of civilian clothing, which marks the first time in the world that this advanced material derived from the aerospace field has been applied to the people's livelihood. The apparel and textile industry has created a new class of fiber materials. From January 21st to 22nd, domestic senior outdoor professionals wore “Polyurized OR95 Apparel” made of “Polyimide Fiber” and other top outdoor brand clothing, which were carried out in the northeast of Changchun at a temperature of 20°C. The extremely cold environment experience of the day. Experience results: warmth, comfort and light performance on foot and at rest are higher than other top outdoor brand clothing.

This is also evidenced by the testing of the relevant professional departments. In the infrared contrast test of the National Infrared and Industrial Electric Heating Product Quality Supervision and Inspection Center, it shows that the warmth performance of the "polyimide fiber" warm clothing is better, so that the same tester's body temperature is higher than the same weight of the world's top fleece. Warm clothing 4-6 degrees Celsius; in the thermal performance comparison test conducted by the China Textile Products Quality Supervision and Inspection Center, the conversion warming rate of the 120 gram "polyester OR95" flakes made of "polyimide fiber" was 70.5%. The same is 120 grams of the world's top hollow polyester warm flakes (samples taken from the polar science test), the conversion rate is 64.9%; the 135g weight of the Polyurethane OR95 flakes has a conversion rate of 75%, the same The conversion warming rate of the world's top hollow polyester thermal flakes weighing 265 grams is 76.1%. Under the condition that the weight difference is nearly doubled, the polyester fiber â—‹R95 flakes made of polyimide fiber embodies the magical warmth effect. Polyimide Polyester Fiber has also passed the OEKO-100TEX Baby Ecology Confidence Textile Certification of the Swiss Textile Testing Institute in Europe, becoming a first-grade product for infants. In the "Textile Light" 2013 China Textile Industry Federation Science and Technology Progress Awards, it was voted the first prize of China Textile Industry Science and Technology Progress Award.

It is reported that polyimide fiber is a typical representative of organic high-performance fibers and has various chemical structures. Its excellent mechanical properties and thermal stability, can withstand high (low) temperature, radiation resistance, widely used in aerospace, military and environmental protection, but its production technology and products have long been used by a few foreign companies. monopoly. The Institute of Applied Chemistry of the Chinese Academy of Sciences completed the basic research of polyimide after 50 years. Shenzhen Huicheng Electric Co., Ltd. invested nearly 500 million yuan to build the world's only comprehensive polyimide production base - Changchun Gaoqi Polyacyl Imine Materials Co., Ltd. After five years, Gaoqi Company realized the industrialization of the research results of Changchun Yinghua Institute of the Chinese Academy of Sciences, and built a 1,000-ton polyimide fiber production line with independent intellectual property rights. At present, the company has produced breakthrough new materials with excellent indicators. This new material has a wide range of applications. It is used in military industry. The registered trademark is Polyester 8121, which is used for environmental protection. The industrial dust filtering of polyester has broken the monopoly of foreign technology and reversed the passive situation of high-temperature and high-end filter materials relying on imported fiber in China's large dust collectors.
