Melt spinning of polypropylene |
摘要 |
A process of melt spinning polypropylene the improvement comprising adding to the polypropylene before it is melt spun, a small proportion of a polymer capable of forming an anisotropic melt in the temperature range at which the polypropylene may be melt spun and then melt spinning the polymers together at a wind up speed of less than 1000 meters per minute whereby in the process there is a suppression of wind up speed compared with the process carried out in the absence of the added polymer.
