Fiber diameter fluctuation along the length direction
Fenómeno do problema
The fiber diameter fluctuates along the length direction, the thickness is uneven, exceeding the allowable deviation of the standard
Análise das causas
（1）The spinning temperature fluctuates and the melt viscosity changes
（2）The metering pump supply is unstable
（3）The spinning speed fluctuates
（4）The cooling conditions are unstable (air temperature/air speed)
（5）The spinneret hole diameters are inconsistent
Solução
（1）Stabilize the spinning temperature
（2）Ensure stable supply of the metering pump
（3）Stabilize the spinning speed
（4）Stabilize the cooling air temperature and air speed
（5）Check the uniformity of the spinneret hole diameters
Conclusão principal
Fiber diameter requires stable spinning parameters
