Embodiment Construction

[0047] like figure 1 , Figure 5 As shown, the nanofiber production apparatus 100 of the present invention includes: a nanofiber production apparatus 10, which is equipped with a solution ejection nozzle 11 for ejecting a polymer solution obtained by dissolving a raw material polymer in a volatile solvent, and a high-pressure high-temperature The hot air ejection nozzle 12 of high-speed gas; the box body 60, which allows the nanofibers produced by the nanofiber production device 10 to freely float; Suction trap. In the nanofiber manufacturing device 100 of the present invention, between the nanofiber generating device 10 and the nanofiber collecting surface 51 of the nanofiber collecting device 50, at least one nanofiber nozzle for suppressing generation by the nanofiber generating device 10 is provided. The flow path restraining mechanism 90 for the straight flow of outflow. As a result, the flying of the nanofiber ejection flow in a straight line is suppressed, and the fl...

Abstract

[PROBLEM] To produce nanofiber sheets that are homogeneous over the entire surface of the sheets. Furthermore, to prevent a polymer solution that fails to become nanofibers in a fiber generation device from turning into droplets or small polymer masses that fly straight toward a nanofiber collection device, thereby avoiding directly hitting a nanofiber collecting surface of the nanofiber collection device. [SOLUTION] A nanofiber production apparatus provided with: a nanofiber generation device equipped with a liquid discharge nozzle for discharging a polymer solution in which a polymer has been dissolved in a solvent, and a hot air discharge nozzle for discharging a high-temperature, high-speed gas at high pressure; and a collection device for suctioning and collecting nanofibers generated by the nanofiber generation device. A flow path suppression means is provided between the nanofiber generation device and the nanofiber collection device, said flow path suppression means causing the nanofibers generated by the nanofiber generation device to float so that the flow of nanofibers generated by the nanofiber generation device do not directly fly straight into the nanofiber collection device.

Description

technical field [0001] The present invention relates to a nanofiber production device and a nanofiber production method for producing nanofibers from a polymer solution. In particular, it relates to a nanofiber production device and a nanofiber production method for producing nanofibers from a polymer solution obtained by dissolving a base polymer in a solvent. More specifically, the present invention relates to a nanofiber sheet production device and a nanofiber sheet production method for producing a homogeneous nanofiber sheet from a polymer solution obtained by dissolving a base polymer in a solvent. Background technique [0002] In this specification, the term "nanofiber" refers to manufactured fibers having a fine diameter of several nanometers to several hundreds of nanometers in average fiber diameter, and also includes aggregates thereof in which the fiber diameters are appropriately distributed. [0003] In addition, in this specification, specifically, a melt obt...
