SPINNING APPARATUS FOR PRODUCING TWO-INGREDIENT COMPOSITE NANOFIBERS, AND METHOD FOR PRODUCING TWO-INGREDIENT COMPOSITE NANOFIBERS USING SAME

摘要

The spinning apparatus for producing two-ingredient composite nanofibers, according to the present invention, comprises: (i) a spinning tube (T) which comprises a spinning tube body (Ta) having a cylindrical or conical shape and a polygonal tubular hollow part (Tb) formed, along the length direction of the spinning tube body (Ta), inside the spinning tube body (Ta) and has a structure in which the vertex areas of the polygonal tubular hollow part (Tb) are in contact with the outer circumferential surface of the spinning tube body (Ta); and (ii) a spinning solution distribution tube (1) which is connected to the spinning tube (T), comprises a spinning solution distribution tube body (1a) having a cylindrical or conical shape, a polygonal tubular hollow part (1b) formed, along the length direction of the spinning solution distribution tube body (1a), inside the spinning solution distribution tube body (1a), and nozzles (1c) installed, along the length direction of the spinning solution distribution tube body (1a), in the respective vertex areas of the polygonal tubular hollow part (1b), and has a structure in which the vertex areas of the polygonal tubular hollow part (1b) are in contact with the outer circumferential surface of the spinning solution distribution tube body (1a). The present invention uses an electrostatic force and a centrifugal force at the same time, thus can produce two-ingredient composite nanofibers with high productivity (discharge volume), facilitates solvent volatilization and recovery, effectively prevents a (drop) phenomenon in which a spinning solution drops onto a collector in a solution state, not a fibrous state, and thereby improves the quality of a two-ingredient composite nanofiber web.
