Abstract: The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the morphology of which is controlled by the use of a polymer additive to form a polymer blend with polyacrylonitrile, which is then subjected to certain coagulation and washing conditions. The present disclosure also relates to carbon fibers produced by processing the polymer fibers made.

Abstract: The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the properties of which are controlled by certain parameters of the process, such as the amount of jet stretch, the amount of wet stretch, and the amount of hot stretch employed. The present disclosure also relates to a process for producing carbon fiber from such polymer fibers.
