发明名称 Air gap spinning process for aramids
摘要 An improved process for spinning aramids from solution using the air gap wet spinning method involves using a coagulant that contains 1 to 1000 ppm by weight of an organic polymer that acts as a drag reducer. Improved productivity and/or finer aramid fibers is obtained with no deterioration of fiber physical properties.
