Abstract
A basic study of melt spinning of polypropylene is reported. This study is aimed at developing a new technology for the manufacture of fine denier polypropylene fibers for clothing end uses. It was found that the molecular weight of the polypropylene resin has-a key influence on structure development in the fiber spinline. By aiming at achieving a smectic structure of the as-spun fiber through a controlled degradation of polypropylene, we can spin fine denier good quality polypropylene fibers at temperatures below 280°C and speeds up to 2000 meters/minute.
