"P", the "polyimide fiber" known as "a href=" http://sjfzxm.com/news/index_s.asp "gold wire < /a" has been applied to the field of civil clothing recently. This marks the first time that China has applied this advanced material from the a href= "http://sjfzxm.com/ news/index_s.asp" space "/a" field to the people's livelihood for the first time in the world, and has created a new type of fiber material for the clothing and textile industry.

In from January 21st to 22nd, domestic senior outdoor professionals wore "a href=" http://sjfzxm.com/news/index_s.asp "Yi Lun OR95 < /a" dress made of "polyimide fiber" and other top outdoor brand clothing for two days of extreme cold environment in the outdoors of 20 degrees below zero in Northeast Changchun.

Experience result: warmth, comfort and light performance on foot and rest are higher than other top outdoor brand clothing.

The test of the relevant professional departments has also proved this point in < p >.

The temperature of the same experimenter is 4 to 6 degrees Celsius, which is the same as the weight of the world's top warmest clothing. In the comparative test of the thermal performance of the China textile products quality supervision and inspection center, the conversion rate of 120 grams of "polyamide fiber" made of "polyimide fiber" is 70.5%, and that of the world's top hollow polyester heat preservation floc (the sample is taken from polar examination clothes) is 64.9%. The conversion rate of the heat preservation rate of 64.9% grams is 120 kg, and the conversion rate of 135 grams of Yi Lun OR95 floc is 75%, and the equivalent heat preservation rate of the world top hollow polyester heat preservation membrane is 76.1%. In the infrared contrast test of the national infrared and industrial Electrothermal Products Quality Supervision and inspection center, it is shown that the thermal insulation performance of "a href=" http://sjfzxm.com/news/index_s.asp "polyimide fiber < /a > is better.

Under the condition that the weight difference is almost doubled, the R95 fabric made of polyimide fiber embodies the magical warmth retention effect.

The polyimide Yi Lun fiber has also been approved by the European Swiss Textile Testing Institute, OEKO-100TEX baby eco confidence textile certification, and has become a first-rate infant product.

In the "textile light" 2013 China Textile Industry Federation of science and technology progress award selection, was voted the first prize of science and technology progress of China textile industry.

< p > it is reported that polyimide fibers are typical representatives of organic high-performance fibers and have many kinds of chemical structures.

Its excellent mechanical and thermal stability can withstand high (low) temperature and radiation exposure. It is widely used in the fields of aerospace, military and environmental protection, but its production technology and products are monopolized by a few foreign companies for a long time.

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, has completed the basic research of polyimide in 50 years. Shenzhen Hui Cheng Electric Limited by Share Ltd invested nearly 500 million yuan, and built the world's only comprehensive polyimide production base, Changchun Gao Qi polyimide material Co., Ltd.

Gao Qi company has gone through 5 years to realize the industrialization of Changchun Research Institute of Chinese Academy of Sciences, and built a 1000 ton polyimide fiber production line with independent intellectual property rights.

At present, the company has produced new breakthroughs with excellent indicators. This new material is widely used in many fields. It has a special high-strength Yi Lun product used for military industry and registered trademark of Yi Lan 8121. In addition, Yi Lun, which is used to filter dust in environmental protection industry, has broken the monopoly of technology at home and abroad, reversing the passive situation of high temperature and high quality filter materials imported from China.
