The mechanical properties of P. A. N fibers and Co-polymer fibers were studied, and it was shown that the Bu OH-D. M. F spinning system is an excellent method, for instance, high tenacity (>3g/den) fiber can be spun from ηsp/C=0.075 (lgr P. A. N/1, 000cc D. M. F, 30°C) polymer and the other properties are same as these of “Orlon” and “Acrilan”
