Experimental investigation of melt fiberization from a perforated rotor spinning machine

- Fructose fiber formation was studied experimentally on a spinning perforated rotor.
- Final fiber diameter increases with Weber number and melt superheat.
- Melt jet surface is initially smooth with a spirally shaped contour.
- During solidification, melt jets are destabilized by transversal disturbances.
- Extent of stable fiber formation zone increases with Weber and Ohnesorge number.
