Once the polymerization has occurred it is forced into a cast to form a ribbon

Once the ribbon has cooled it turns to hard chips, once completley dried the chips are then melted and spun.

The melted fibers are put in spinnerets and cool upon hitting the air and are wound onto cylinders

The fiber has now been heated and stretched to about five times its original size. It is now ready to be cut and sold.
