Preparation process of special fiber

2022-11-16

Most special fibers are made by wet spinning. Some special fibers are difficult to prepare. For example, the traditional spinning technology is used to spin linear or low molecular weight fibers, and then cyclization, cross-linking, metal chelation, high temperature heat treatment, surface physical and chemical treatment or plasma treatment are carried out to prepare 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; Others use existing synthetic fibers to obtain various ion exchange groups through functional group reaction or convert them into special fibers.
