Conclusions
The effect of fluctuations in polycaproamide melt temperature before the spinneret on flow rate of the melt through a spinneret hole, and, consequently, on the linear density of elementary filaments, has been investigated.
It has been found that even a slight polymer melt temperature drop — even of 5°C — can lead to 12% variations in filament linear density.
