Preoxidized fiber powder

The products are made from a range of asbestos-free fibers to form yarn and cloth of various specifications., which become the skeleton material of friction sealing materials and meet the requirements of environmental protection.

Short-cut preoxidized silk fiber is made by cutting PAN-based preoxidized fiber filaments into short lengths. Being composed of equal length fluff, short fiber offers uniform dispersion, versatility of mixing methods and an easy processing step compared to longer filaments, making it an ideal solution for applications where filaments are not ideal, especially in the reinforcement of composite materials.

Special fibers have different special properties, such as strong corrosion resistance, low wear, high temperature resistance, radiation resistance, flame resistance, high voltage resistance, high strength and high modulus, high elasticity, reverse osmosis, filtration, adsorption, ion exchange, light conduction, conductivity, and various medical functions.

Most specialty fibers are made by wet spinning. Some special fiber preparation processes are more difficult, such as spinning linear or low molecular weight fibers using traditional spinning techniques, and then undergoing cyclization, cross-linking, metal chelation, high-temperature heat treatment, surface physicochemical treatment or plasma treatment to produce finished fibers; In addition, new spinning processes such as lotion spinning, reactive spinning, liquid crystal spinning, dry jet wet spinning, phase separation spinning, high voltage electrostatic spinning, high-speed airflow melting jet and special composite spinning technologies are needed; Some also utilize existing synthetic fibers to obtain various ion exchange groups through functional group reactions or convert them into special fibers.
