Microporous polypropylene hollow fibrous membranes may be prepared by the melt spinning and coldstretching (MSCS) or thermally induced phase separation (TIPS) method.
The results show that ASS's yield strength can be improved significantly by coldstretching technique and thus the wall thickness of pressure vessel can be substantially reduced.
