Abstract:
Continued efforts with Profax 6523 have resulted in fibers with a tenacity of 11.5 gpd and an elongation at break in the neighborhood of 15. Spinning has been extended to the higher and lower molecular weight polypropylenes. Higher molecular weights are expected to give higher strengths experiments to date have not been of a caliber to support this hypothesis. The development of tenacity from the drawing operation has been explored over a wide range of temperatures both for polypropylene and for polyethylene. Reasonably optimum conditions have been established for both cases. Multifilament polyethylene was spun from Marlex 6002, 6009, and 6050. The maximum fiber tenacity developed by a two step drawing operation was 11.1 gpd. The higher molecular weight Marlexs gave higher tenacities. Author
