On November 28, 2023, JSAS, a leading Chinese manufacturer of polyimide high-performance fibers, announced:
JSAS was granted two patents by the China National Intellectual Property Administration, including one invention patent and one utility model patent.
Invention patent "A blue polyimide fiber and its preparation method". The blue polyimide fiber prepared by this method has good high-temperature fading resistance, excellent tensile strength, flexibility and elasticity.
JSAS is a national high-tech enterprise engaged in the research and development, production, and sales of high-performance polyimide fibers and their subsequent products. The company has the world's first thousand ton dry spinning polyimide fiber production line, and its projects and products passed national level appraisal in 2014. The "reactive spinning" technology is internationally leading.
The company's main products are polyimide short fibers and long filaments, which have excellent high-temperature resistance and excellent mechanical, insulation, flame retardant, radiation resistance, chemical resistance, and other properties.
Polyimide fibers and products have been widely used in fields such as high-temperature flue gas dust removal, special protection, industrial flame retardant insulation, and structural and composite materials.
The company has established research and development institutions such as provincial polyimide fiber material engineering technology research center, provincial polyimide material engineering research center, and textile industry polyimide fiber technology innovation center. It has obtained 41 invention and utility model patent authorizations, and has independent intellectual property rights for "dry spinning" polyimide fibers. It has won the second prize of the National Science and Technology Progress Award in 2016 In 2015, the China Textile Industry Federation won multiple honors including the first prize of "Textile Light" Science and Technology Progress Award.
The high-strength and high modulus series of polyimide fiber products have passed the Swiss Oeko Tex certification ® Standard 100 Confidence Textile Authorization Certification and China Chemical Fiber Industry Association Green Fiber Brand Certification.
