The　spinnability　and　mechanical　properties　of　poly(propylene)　(PP)/zeolite-supported　Ag+　(zeolite-Ag)/ethylene　vinyl　acetate　(EVA)　ternary　blend　fibers　were　studied.　It　was　found　that　the　spinning　temperature　of　the　ternary　blend　fibers　was　decreased　in　the　presence　of　EVA.　The　addition　of　2　wt　%　EVA　substantially　improved　the　spinnability　of　the　blend　system　by　enhancing　its　flowability.　It　was　also　found　that　the　ternary　fiber　with　EVA(28)　(28　wt　%　vinyl　acetate　content)　showed　balanced　improvement　of　mechanical　properties　by　a　concomitant　increase　in　modulus　and　tensile　strength.　The　improvements　of　spinnability　and　mechanical　properties　suggested　that　a　core-shell　structure　of　zeolite-Ag/EVA(28)　particles,　with　zeolite-Ag　as　the　core　and　EVA(28)　as　the　shell,　was　formed　and　remained　during　the　melt-mixing　process　of　the　blended　chips　and　during　the　course　of　fiber　processing.　EVA　probably　enhanced　the　binding　between　the　zeolite-Ag　and　the　PP　matrix,　as　made　evident　in　SEM　microphotographs.　(c)　2005　Wiley　Periodicals,　Inc.
