Preparation of Fibers by Melt-Spinning

The simplest method of melt-spinning is to melt the polymer in a test tube, dip a glass rod in the melt and pull it out slowly. The threads obtained in this manner are short and irregular so that they are not well suited for subsequent investigations. 

Much better for melt-spinning are extruders. There are miniature versions available that allow a controlled manufacture of fibers even with a few grams of polymer.
