Beschreibung
Zusammenfassung:	Breathable non-wettable non-woven materials include a mass of melt-blown, non-woven fibers formed of a terpolymer of tetrafluroethylene, hexafluoropropylene and vinylidene fluoride monomers. Most preferably, the materials of the present invention are in the form of fabric structures which can be processed to form a variety of products for numerous end use applications, such as for garments, bandages, barrier vents, filter media and the like. In especially preferred form, the melt-blown non-woven fibers are comprised of a THV terpolymer formed of between about 30 to about 70 wt. % of teirafluoroethylene monomer, between about 10 to about 20 wt. % of hexafluoropropylene monomer, and between about 20 to about 65 wt. % vinylidene fluoride monomer.
