ABSTRACT:
A process of making a fiber includes the sequential steps of extruding as a stream solution of a polymer having a polymer concentration of 4-24 weight % into a non-coagulating fluid, stretching the stream while in the non-coagulating fluid, passing the stream through a first coagulating bath, stretching the stream in a non-coagulating fluid, and passing the stream through a coagulating bath to sufficiently increase the polymer concentration in the stream to form the fiber.
