Application Summary AI generated
GB/T 39025-2020 specifies the technical requirements, test methods, inspection rules, and packaging for spun-dyed polyimide staple fibers, which are inherently colored synthetic fibers with high thermal stability and flame resistance. It is applied in the production of high-performance textiles, such as protective clothing for firefighters, industrial filtration materials, and aerospace insulation, where consistent color and durability under extreme conditions are critical. The standard ensures quality control during manufacturing and procurement for industries requiring specialized fibers that maintain color and performance after repeated high-temperature exposure.
