It is used for rayon and other materials by separating from the solidified liquid and fiberizing.
The "wet nozzle" for synthetic fiber spinning is a method where polymers (high molecular materials) are extruded from the nozzle to discharge the spinning dope into a coagulation liquid, causing solidification or regeneration through contact with the coagulation liquid, and then separating from the coagulation liquid to form fibers. It is used for rayon, vinylon, acrylic, and others. For more details, please download the catalog.

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.
