PROBLEM TO BE SOLVED: To solve the problems in which: as methods for producing a nanofiber textile product, the Melt Blown method and the ESD method have been used; but, in the Melt Blown method, fibers are formed as short fibers, and there has been difficulty in forming nanofibers; in addition, there has been a problem of being unable to mass-produce the fibers; although the ESD method has made it possible to form nanofibers, mass production is difficult, and there is concern about a safety problem because an organic solvent is used; and thus, the improvement of a nanofiber production method has been desired.SOLUTION: In the solution according to the present invention, a nanofiber generator comprises: an injection nozzle for discharging a molten polymer; an air nozzle for blowing high-speed, high-temperature air; and a heating guide member having the function of promoting drawing for the formation of nanofibers. Thereby, the further thinning of the nanofibers is made possible.SELECTED DRAWING: Figure 1 |
