Continuous Spun Fibers via Centrifugal Force Spinning

Centrifugal Force Spinning (CFS) provides an alternative fiber spinning method from other well-developed fiber spinning methods, and allows for quick and efficient manufacture of continuously spun fibers. In this contribution, a list of ideal polymer solution properties such as polymer entanglements, extensional relaxation time, and evaporation rate is compiled through torsional rheometry, Dripping-onto-Substrate (DoS) protocols, and thermogravimetric analysis (TGA). These properties are paired together with fiber spinning process parameters to provide an optimized processability map, predicting fiber formation and morphology. The resulting fiber morphologies are observed through SEM and the fiber mat mechanical properties are characterized.
