Uneven fiber color
Sorun Belirtisi
The fiber color is uneven, with obvious color difference between batches or within the same roll
Neden Analizi
（1）The color masterbatch dispersion is uneven
（2）The spinning temperature fluctuates and the pigment thermal stability is poor
（3）The metering pump supply fluctuates
（4）Insufficient mixing during material change
（5）The pigment has insufficient heat resistance and discolors at 240-280°C
Çözüm
（1）Improve the color masterbatch dispersion and add mixing sections
（2）Stabilize the spinning temperature
（3）Stabilize the metering pump supply
（4）Fully flush when changing materials
（5）Select pigments with better heat resistance
Temel Çıkarım
Fiber color difference needs to be addressed from dispersion and temperature
