Preoxygenated polyamide fiber is a type of synthetic fiber that is polymerized from polyamide prepolymer under conditions of
elevated temperature and pressure. It exhibits outstanding properties such as flame retardancy, high thermal resistance, and
exceptional chemical stability, resulting in a broad range of applications across various fields:
■ Textile Industry: Pre-oxidized polypropylene fiber can be utilized for spinning and weaving, finding extensive use in protective
clothing for steel mills, aluminum plants, welding operations, and furnace environments to ensure worker safety. This fiber
supports diverse textile processing techniques including needling, sewing, heat bonding, chemical bonding, air mesh formation, wet
mesh production, ring spinning, drawing processes as well as knitting and weaving. End-use applications encompass aircraft brake
prefabricated components; transportation insulation; flame-retardant layers; fire blankets; welding blankets; kitchen fire
shields; wine hoods; machine shields; thermal barriers; soundproofing materials; vibration-damping linings; flame-resistant
apparel; expansion meshes; along with serving as raw materials for carbonized and graphitized yarns, fabrics and felts.
■ Industrial Sector: Preoxygenated silk fibers demonstrate remarkable heat resistance and corrosion resilience against chemicals
making them suitable for the fabrication of industrial machinery components under high-temperature and high-pressure scenarios.
■ Electronics Industry: Preoxygenated polyacrylonitrile fibers possess excellent electrical insulation characteristics which
enable their application in the manufacturing of high-voltage cables and electronic devices.
■ Other Applications: Additionally, preoxygenated polyacrylonitrile fibers are employed in the production of advanced sports
equipment as well as aerospace technology.
■ In summary, preoxy polyacrylonitrile fibers present significant prospects due to their superior physical and chemical
attributes.
