| Abstract: | The spinnability of metallocene catalyzed polypropylene(miPP) and Ziegler\|Natta polypropylene(ziPP) chips was compared as spun by melt spinning process at the same spinning conditions. The effects of spinning conditions on the structure and properties of their as\|spun fibers were studied. It was found that miPP whose spinnability was profoundly affected by temperatures had fairly good spinning performance at lower temperatures; miPP wound yarn was better in tensility as compared with ziPP wound yarn; and miPP as\|spun fiber had higher orientation degree because of the narrow relative molecular mass distribution. |
