Polymerization Saponification Worker (Synthetic Fiber Manufacturing)
じゅうごうけんかこう（ごうせいせんいせいぞう）
Industry & Occupation
Classification
Summary
Production engineering position that operates polymerization reactions and saponification processes to manufacture polymer raw materials for synthetic fibers.
Description
Polymerization saponification workers manufacture polymers, which are raw materials for synthetic fibers. They charge monomers and catalysts into the reactor, control temperature and pressure to advance the polymerization reaction. Afterward, they add neutralizing agents to the polymer and perform saponification to remove residual acetic acid. They handle a wide range of tasks including monitoring temperature and pressure during reactions, quality inspection via sampling, equipment cleaning and maintenance, and safety management, with requirements for stable process operation and product quality assurance.
Future Outlook
With increasing environmental regulations and energy-saving demands, process optimization and automation are advancing, requiring advanced control skills and digital adaptation capabilities.
