4. Introduction
Melt spinning is the most convenient and economic
method for polymer fiber manufacturing at industrial
scales. In melt spinning, the fiber-forming substance is
melted for extrusion through the spinneret and then
directly solidified by cooling. This method of spinning
is suitable in manufacturing the polyester yarns.

5. Spinning Process
1.Polymer chips is converted to liquid just by heating.
2.The molten polymer is pumped through the spinneret
& extruded filaments are hardened into solid filaments
after emerging.
3. The molten fibers are cooled, solidified and collected
on a take up roller.
4. Stretched is applied for provides orientation of
polymer Chain along fiber axis.

8. Requirements for melt spinning
 The polymer should not be volatile
 The polymer should not decompose in the molten state and the
melting point.
 Polymer should be 30 degree centigrade less than its
decomposition temp
Special features for Melt Spinning:
 High production ( SPG. Speed 1000-2000 m/min)
 Hazard, Non Toxic
 No environment pollution.
 No solvent required .
 Heat of spinning is high.

9. Types of spinneret:
1.Round shape spinneret: The Shape of spinneret is Round.
2.Y-Shape: The shape of spinneret is like Capital ” Y”
3.Cross: The spinneret is like a cross.

10. Advantage of Melt Spinning
1.Can be used for both staple and continuous filament.
2.Direct and simple process.
3.No environment pollution.
4.High production speed (2500-3000) ft/min.
5.Low investment cost.
Disadvantage of Melt Spinning
1. Required more proper maintained of machine.
2.Heat of input is high.
