Morphology structure study of polypropylene hollow fiber membrane made by the blend-spinning and cold-stretching method

摘要

This paper proposes one of simplest ways to prepare polypropylene/easy hydrolytic degradation polyester (PP/EHDPET) microporous hollow fibers by blend spinning and cold stretch process. And it details and investigates the structure properties of as-spun fibers, micropore formation mechanism, and pore structure of the hollow fiber membranes by the scanning electron microscope.
