Preparation and Performance Study of Melt-blown Non-woven Fabric with High Barrier Properties
This article utilized metallocene polypropylene(mPP)for controlled degradation to prepare specialized materials suitable for melt blown processing technology.The results have shown that melt blown nonwoven fabrics prepared by mPP have better filtration performance than the melt blown nonwoven fabrics prepared by Ziegler Nata catalyzed isotactic polypropylene(znPP),thanks to their finer and more uniform melt blown fibers and excellent and stable polarizing performance.Melt blown non-woven fabric prepared by mPP without polar additives exhibits excellent polar performance,mainly due to its higher surface resistance,stronger hydrophobicity,and smaller crystal size and faster crystallization rate of mPP material for melt blown non-woven fabrics.
