Carbon fibers are classified into PAN-based and pitch-based according to the raw materials.
The wet spinning nozzle for synthetic fibers is classified into PAN (polyacrylonitrile) type and pitch (such as coal tar) type based on the raw materials. About 90% of the carbon fiber market is PAN type. PAN-based carbon fibers are obtained by carbonizing PAN precursors (polyacrylonitrile fibers) and possess high strength and high modulus properties. The wet spinning method involves fiber formation from the spinning dope in a coagulation liquid, allowing for a higher number of holes per unit area of the nozzle compared to dry and wet spinning methods.

Company information
About 70 years ago, when synthetic fibers were still considered "imported goods," Nippon Nozzle succeeded in producing nozzles for rayon manufacturing, taking a significant step towards the domestic production of synthetic fibers. Currently, in the synthetic fiber industry, we hold a 15% share of the global market, and our top-class technology is widely recognized worldwide. This is a proud achievement, but it is the result of the steady accumulation of diligent research and development, all stemming from a direct challenge to meet user needs.
