The Preparation of Polypropylene/Polyvinyl Alcohol Ultra-Fine Fibers Using Melt Electrospinning Method

Abstract:

Some polymers like polypropylene (PP), polyethylene (PE), polyphenylene sulfide (PPS) are very hard to be solute in conventional solvents at room temperature, and impossible to be solution electrospun, but they can be easily fabricated into ultra-fine fibers using melt electrospinning. In this study, PP/PVA compound ultra-fine fibers were produced using mlet electrospinning. The effect of PVA content in PP/PVA compound on the properities of resultant fibers was studied. Different plasticizers were added into the compound to find the most effective plasticizer reducing the melt viscosity. It was shown that PP/PVA compound with content of 5% PVA can produce the finest fiber while adding 8% hyper-branched polyester (HBP). In addition, the resultant fibers were made into thin paper using compaction processing, and water absorbability was tested. The results were expected to be used in dyeable PP cloth production and degradable polymer paper production.
