Oil agent shedding of PET fiber
Fenómeno do problema
During subsequent processing of PET fiber, the oil agent sheds and produces powder, and fly increases during weaving.
Análise das causas
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.
Solução
Select an oil agent system compatible with PET; optimize the application process (metering pump oiling); improve oil agent heat resistance.
Conclusão principal
PET fiber oil agent shedding affects the smoothness of subsequent processing.
