It is a method of forming fiber filaments by evaporating the solvent and winding it up.
The "dry nozzle" for synthetic fiber spinning is a method that involves dissolving a polymer (high molecular material) in a solvent to create a polymer solution, which is then extruded through a porous nozzle. This solution is dried with hot air, causing the solvent to evaporate and forming fiber filaments. It is used for materials such as acetate, spandex, and acrylic. The dry spinning nozzle requires a higher level of precision compared to other nozzles. In the case of round hole nozzles, the diameter and length of the holes are important. For shaped hole nozzles, the edge width, edge length, and configuration angle, as well as the angle and cross-sectional shape of the inlet hole, are crucial. Additionally, the share of acetate is the highest in the world. 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.
