Melt Spinning Process

Melt Spinning : The fiber forming material is melted and subsequently passed through the holes of a spinneret. Example ; Polyester, Nylon, Polypropylene etc.

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 Feature Of Melt Spinning :

• High production ( SPG. Speed 1000-2000 m/min)
• Hazard , Non Toxic
• No environment pollution.
• No solvent required .
• Heat of spg high.

Melt Spinning Polymer : 

Polymer	Melting Point
Nylon 6.6	264 degree Celsius
Nylon 6	220 degree Celsius
Polypropylene	167 degree Celsius
PET	264 degree Celsius
