NOZZLE AND HOLE STRUCTURE OF A MANUFACTURING DEVICE OF PREPARING FORTHE NANOFIBERS

摘要

A structure for a spinning nozzle and an air injection port is provided to improve the spinning effect through air injection and prevent solution beads from being formed, by improving the structure of the air injection port. A plurality of spinning nozzles(22) are arranged along a length of an air injection body(24). Air injection ports(24a) are arranged at both sides of each spinning nozzle along the length of the air injection body. Each of the air injection ports is formed in a long slit shape along a width of the air injection body. A lower end of the spinning nozzle is protruded from lower ends of the air injection ports. The spinning nozzle and the air injection body with air injection ports constitute a spinneret(20). Further, a baffle plate(25) is contained in a manufacturing device of preparing ultra fine nanofibers in order to form a minus pressure by forming a close space with air jetted from the air injection ports.
