Abstract

Disclosed herein is a method for manufacturing a composite fiber filter having high efficiency and high functionality, the method comprising: melt-spinning microfiber yarns on a forming rod, which is made of a conductive material, grounded at one end thereof and rotatably driven, using a melt-spinning device, to form on the forming layer a microfiber layer consisting of the microfiber yarns; and electrospinning on the microfiber layer an electrospinnable polymer solution having a given dielectric constant, using an electrospinning device, so as to form on the microfiber layer a nanofiber layers consisting of nanofiber yarns, wherein the microfiber yarns of the microfiber layer and the nanofiber yarns of the nanofiber layer contain silver nanoparticles so as to have an antibacterial function.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a filter unit, and more particularly to an apparatus and method of manufacturing a composite fiber filter having high efficiency, high-functionality and antibacterial activity by combining nanofibers with microfibers.[0003]2. Background of the Related Art[0004]Generally, most microfibers are manufactured through spinning processes such as melting spinning, dry spinning or wet spinning, that is, by extruding and spinning a polymer solution through fine holes by mechanical forces. However, the microfibers manufactured in this manner have a diameter of about 5-500 μm and it is difficult to manufacture nano-scale fibers having a diameter of less than 1 μm. Accordingly, with a filter made of such microfibers, micrometer-sized contaminant particles can be filtered out, but it is in fact impossible to filter out nanometer-sized fine contaminant particles.[0005]Thus, various methods for manufact...
