Wet Spinning of Polyacrylnitrile Fibers 

"In this video, the schematic process of wet spinning of polyacrylnitrile fibers is shown. The polymer is solved in Dimethylformamide. The solution is pumped by the syringe pump into a water bath, in which polyacrylnitrile is insoluble, so the polymer precipitates. Due to the process parameters, a fiber can be formed and taken out from the water bath. "
