Magnesia (MgO) nanoparticles were produced from magnesite ore (MgCO_(3)) using ball mill. The crystalline size, morphology and specific SSA were characterized by X-ray diffraction analysis, transmission electron microscopy and Brunauer-Emmett-Teller method, respectively. MgO nanoparticle-incorporated nylon 6 solutions were electrospun to produce nanofiber mats. Surface morphology and internal structure of the prepared hybrid nanofiber mats were examined by scanning electron microscopy and high-resolution transmission electron microscopy, respectively. The fire retardancy and antibacterial activity ( Staphylococcus aureus and Escherichia coli ) of coated fabrics made from MgOylon 6 hybrid nanofiber are better than those from nylon 6 nanofiber.
