Man Made Fibre Spinning:
The conversion of polymer into fibre is called spinning. The fibre forming substance is made temporal fluid extruded through spinneret & then return to solid state (by solidification) in fibre form.
Types of spinning:
- 1.Melt spinning.
- 2.Dry spinning.
- 3.Wet spinning.
Spinneret:
A nozzle or plate provided with fine holes or slits through which a fibre forming solution or melt is extruded in fibre manufacture is called spinneret. This is most important part of a machine. The number of holes, their size & shapes vary with the filament desired. It was invented by ozanam in 186
Shape of spinneret hole:
- Round
- Triangle
