4
Q
Wet spinning
A
Polymer solution extruded into chemical fluid which solidifies filaments.
5
Q
Dry spinning
A
Polymer solution extruded into stream of warm air
Evaporates solvent
Solidifies filaments
6
Q
Melt spinning
A
Molten polymer extruded into cold air
Cools and solidifies filaments
7
Q
Spinneret
A
Shape of filaments can vary eg)
Round - shiny
Triangular - mimic silk
To change reflection of light/insulation
