- Description
-
Aramid pulp is the product of microfibrillation of para-aramid fiber filaments. In the process of microfibrillation, due to the special mechanical action, the surface of the filament is partially destroyed, forming a large number of dendritic microfibers connected with the precursor. Therefore, aramid pulp not only has the high strength of aramid filament, but also has a high specific surface area.
Aramid pulp is mainly used to produce high-performance friction materials and gaskets.

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.
