Wet Spinning of Polyacrylnitrile Fibers

Показать описание

"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. "

I couldn't find a clearer and simple video to exhibit wet spinning - this was great!

So interesting! I was so puzzled with the term until now. I never knew this was the process for this. So amazing

Beautiful… what is the name of the machine

Simply amazing! It helped me a lot in a college project!

Is the other ways in which to precipitate the material? Like, for example, in a mold? Like, lets say you had a mold in a water bath, and you had high volume channels that you could direct the pan/dmf into- could you fill the mold?

Where could I get my hand on the spinning kit? Was it a DIY makeup? Cheers
