Problems solved by technology

[0002] PBO fiber is an organic high-performance fiber with four "ultra-high" properties of "ultra-high strength", "ultra-high modulus", "ultra-high heat resistance" and "ultra-flame retardancy". Textile raw materials, but the only disadvantage is that the light aging performance is poor, which makes it lose its color in the strong sunlight environment with excellent high-strength performance
