Industry & Occupation
Classification
Summary
A manufacturing job that uses bleaching agents to remove pigments and dirt from synthetic fibers, achieving whitening and uniform color tones. Engages in operation of production equipment, process management, safety, and environmental conservation.
Description
Synthetic fiber bleaching workers are specialists who remove pigments and dirt structurally and superficially present in fibers such as polyester, nylon, and rayon using bleaching agents like hydrogen peroxide or sodium hypochlorite to achieve uniform whitening. Operators handle feeding raw fibers, preparing and adding bleaching agents, continuous monitoring of pH and temperature, managing residence time, and operating washing and drying processes. Quality inspections involve whiteness measurement using colorimeters and visual checks, with non-compliant products fed back into the process. Handling of hazardous chemicals, management of wastewater treatment equipment, and compliance with safety, health, and environmental conservation standards are also important tasks. Performs regular equipment maintenance and troubleshooting to balance productivity and quality.
Future Outlook
While efficiency improves with the introduction of low-environmental-impact technologies, eco-bleaching processes, and automation advancements, the demand for skilled workers with advanced safety and quality management skills is expected to remain stable.
