ABSTRACT:
Polymer fibers are made from a solution of polymer in solvent by subjecting the solution to shear forces in a confining space by introducing a gas stream into the space in a manner to create a rotary gas flow therein and to cool the solution to a temperature at which polymer precipitates from the solution in the form of fibers.
