Drawing
The spinning fluid solidifies when it emerges from the spinnerets. There are some microfibrils in side of filament which are not very well ordered. By drawing the filament, these disordered microfibrils will become more oriented in the direction of the filament axis. The filament’s strength comes from the formation of crystalline regions within the microfibrils and their orientation along filament axis.
- Drawing of fibres : higher orientation, more crystalline
- Higher tenacity – Low elasticity
