Oil agent shedding of PET fiber
Fenómeno del problema
During subsequent processing of PET fiber, the oil agent sheds and produces powder, and fly increases during weaving.
Análisis de la causa
The bonding force between the oil agent and the fiber surface is insufficient; the oil agent has poor heat resistance and volatilizes or decomposes during drawing and heat setting; application is uneven.
Solución
Select an oil agent system compatible with PET; optimize the application process (metering pump oiling); improve oil agent heat resistance.
Conclusión clave
PET fiber oil agent shedding affects the smoothness of subsequent processing.
